Teacher’s pack for delivering educational fieldwork at Oxwich National Nature Reserve (NNR). This pack is aimed at Key Stage 2 although much of the material is relevant for Key Stage 3 and can be easily adapted. Many of the activities and resources can be adapted to meet the needs of different abilities within the classroom. The pack includes an investigation into the habitats and the organisms living within Oxwich NNR which can be undertaken by a class as part of their Science and/or Geography enquiry and investigation. The pack is matched to the National Curriculum for Wales 2008, the National Curriculum for England 2007 and the Skills Framework for 3-19 year olds in WalesWelsh Assembly 2008. The unit is also matched to ESDGC- A Common Understanding for Schools. Welsh Assembly 2008 It is primarily Geography focused but is cross curricular. There are strong curriculum links with Science, English, Maths, PSE, ICT and other curriculum areas. Teachers are encouraged to undertake the whole scheme of work for students to gain a full understanding of all the methodologies. However, the pack is designed so teachers can select individual lessons, activities or resources to meet their curriculum and the individual needs of their students. Visits to Oxwich are free and can be undertaken by any competent teacher. Please contact the Countryside Council for Wales (CCW) for more details, 0845 1306229 or Dawn Thomas of Nature days 01792 392919. Page 3 All resources are available on disk available from the warden of Oxwich and Nature days naturedays@reynoldston.com Site information. Oxwich National Nature Reserve can be reached by the minor road off the A4118 west from Swansea. Grid Reference: SS 500 864 Postcode: SA3 1LS Map of location. Swansea Facilities. The site has a large car park owned by the Penrice Estate which does charge. There are toilets on the beach which are open during the summer months. There are also City and County of Swansea toilets located along the road towards the Oxwich Bay hotel which are open throughout the year. These can be accessed from the beach through the sand dunes. There is no permanent CCW presence at Oxwich NNR or any information centre. For information on the site please contact CCW head office at Bangor on 0845 1306229 or contact Dawn Thomas of Nature Days 01792 392919 naturedays@reynoldston.com There is a shop opposite the car park which is open during the summer season which sells refreshments. There is no shelter on the dunes. There is some shelter at the back of the site in the woodland. Parts of the reserve are open access, while other areas are open to groups by arrangement only, such as the freshwater marsh across the road from the car park. Page 4 In Oxwich village there are numerous campsites and a hotel with a restaurant. Frequently asked questions. 1. Where has the visitor centre gone? It was removed in 1995 for a number of reasons including loss of staff and relocation to the central Swansea, We hope that it will be replaced in due course. 2. Can anyone visit the nature reserve and where can we walk? Everyone is welcome to the nature reserve and you can walk wherever you like on the dunes, beach and through both woodlands [Nicholaston and Oxwich] but access to the marshes is permissive and can be dangerous. Is camping allowed on the dunes or beach ? 3. There is no camping allowed anywhere on the beach nor within the nature reserve boundary. What does SSSI mean? Site of Special Scientific Interest. The purpose of SSSIs is to safeguard, for present and future generations, the quality, diversity and geographic range of habitats, species, geological features throughout Wales. 4. 5. What is the rarest thing in Oxwich? We have many rare or uncommon species in the reserve, Vertigo angustior (Narrow mouthed whorl snail) Purple gromwell (flower found in Crawley Bluff) Vernal Colletes (mining bee) Dune Gentian (Gentianella uliginosa) and possibly Bittern. 6. Why do you cut trees? We cut deciduous scrub from the dunes and slacks because it dries out the dunes and overshadows flowering plants. 7. What do the horses do? They graze the sand dunes and keep down the vegetation allowing the smaller plants to flourish and hopefully increase the general biodiversity. 8. Is pond dipping allowed? There are a few areas where this is possible, teacher supervision is always recommended. 9. Do we need to contact anyone before we visit and who do we contact? You must contact the Countryside Council For Wales on 0845 1306229 so we can advise on any health and safety issues, events or any other relevant information. Or Dawn Thomas on 01792 392919 dawn.thomas@naturedays.co.uk Page 5 10. When is the best time to visit? Between June and August, when most of the flowers and butterflies are flourishing. But the reserve has field work opportunities in all seasons and is less busy out of season. Background to Oxwich National Nature Reserve. History. Oxwich Bay has been made by the sea washing away the soft shale rocks that lie in between the harder limestone headlands at either side of the bay. This has taken millions of years. The sea has also brought the sand which forms the beach and the dunes. The limestone on each headland was formed from mud and the remains of sea animals settling on the sea bed. Over millions of years this sediment forms rocks which may be thousands of metres thick. The rocky shore on the west side is formed by pieces of limestone from the cliffs on that side. The bay at one time stretched further inland all the way to the back of the reserve Ships used this inlet as a harbour. Over time about 25,000 years ago the tide built up a shingle bank which was covered with windblown sands to form the present sand dunes. Formation of the Fresh and Salt water marshes. The lagoon trapped behind the sand dunes eventually silted up with sand blown in from the dunes and beach to create a fresh water and salt water marsh. In 1750 Thomas Mansel Talbot , the then owner of Penrice Estate built a sea wall to the north of the dunes enclosing the salt marsh. He then dug an ornamental lake which ran the length of the marsh and an extensive system of drainage channels that took away the water which flowed into the marsh from streams. The land was converted into rough pasture used for grazing cattle. This area was used to grow corn and for grazing until the 1950s. Neglect in maintaining the drainage channels led to the creation of an extensive reed bed. Management. Oxwich is a National Nature Reserve, (NNR) and a Site of Special Scientific Interest, (SSSI). The reserve was established in 1963 through a management agreement with Penrice Estate and by 1983 most of the area was purchased by the Nature Conservancy Council, now the Countryside Council for Wales. Oxwich was designated a NNR because it has one of the richest varieties of coastal habitat in Britain. The combination of rocky and sandy shores, sloping headlands and cliffs, sand dunes and marshes support an exceptional variety of wildlife. Over six hundred kinds of flowering plants alone have been found. One of the reserve's key characteristics is how, in its current form, it is very much the result of both natural processes and man's influence. The two main aims of the reserve are: 1. To protect, maintain and, if possible, enhance the wildlife and outstanding features. 2. To allow as much public access as is compatible with the primary aims of conservation and research. There are a number of threats to Oxwich NNR. •Erosion –blowouts. People lighting fires on the fore-dunes and footpath erosion which exposes the sand to the wind which then removes the sand from the system •Scrub and bracken invasion – due to natural dune succession (Psamosere) more and more non specialist plants grow on the stable dunes. This is due to the natural process of succession and less grazing by rabbits and stock. Page 6 •Reduction in sediment supply – due to dredging off the coast at Helwick Bank. •Tipping and litter – from the many visitors (250-300,000 visitors a year). Page 7 If preservation of the rare and highly adapted plants and animals is to succeed at Oxwich then the different habitats must be nurtured and managed. If the dunes are allowed to turn into woodland then the sand dune plants will be lost. The rangers at Oxwich are busy managing the site to ensure the number of different plants is maximised. They do this by; • Picking up litter • Creating paths and viewing platforms and guided walks to accommodate people. • Careful monitoring of species and communities to see what is growing where. • Bracken bruising with a roller to try to slow the growth of bracken. • Removing scrub and trees growing where they shouldn’t be on the dunes, especially in the dune slacks, (slacks are where the level of the ground is lower that the water table and so are much wetter than the surrounding dunes). • Grazing the meadow and dunes with ponies to help keep the scrub away. • Digging new slacks. • Clearing the overgrown plants so that there is some open water in the reed bed. Habitats found within Oxwich NNR. One of the main reasons for Oxwich being made a National Nature Reserve is the presence of a mosaic of different habitats within a relatively small area, about 200 acres. These include a calcium-rich dune system with dune slacks and salt marsh, freshwater lakes and marshes and adjacent wooded areas on limestone slopes as well as the sandy shore and rock pools. Strandline. Created from the flotsam and jetsam washed up by the sea at high tide. When the tide recedes back out to sea objects are left at the top of the beach creating a line of stranded material both natural and manmade. This strandline provides an unlikely habitat for a small number of adapted species. Since the sand is very unstable there are no living plants capable of growing here. The basis of all the food chains on the strand line is the rotting seaweed brought in by the tide. A large population of sandhoppers lives on this dead and decaying seaweed and these in turn are eaten by the rare strandline beetle. Sandhoppers are popular prey for turnstones, rock pipits and sandpipers foraging on the strandline. The contents of the strandline can provide clues to the animals that live in the sea, what they look like, the type of eggs they lay and sometimes even how they die. Marine and land animals, such as sea birds and foxes, may scavenge on the strandline, and the decaying debris blown up the beach may eventually become soil to support sand dune plants. Sandy shore. The sandy shore looks like a barren habitat once the sea has receded and exposed its vast extent. No plants or seaweed can hold on to the moving sand and the animals living here must survive on the tiny algae and bacteria and bits of dead and decaying matter hidden between the grains of sand. But hidden underneath the sand are creatures which burrow down into the sand to avoid the sea birds. Worms such as Lugworms live in ‘U’ shaped burrows 20-40cm deep. At the surface the head end of the burrow is marked by a small saucer-shaped depression in the surface of the sand. The tail end lies 2-3 inches from it and is marked by a highly coiled cast of sand. The lugworm lies in this burrow with its head at the base of the head shaft, swallowing sand from time to time to eat the algae found within it. Birds such as the curlew have evolved a curved beak to enable them to reach the worms as they lie in the bottom of their burrow. Oystercatchers probe wet sand for cockles and tellin, using their long red beaks. Plovers and other waders with short beaks catch shrimps and other small crustaceans at shallow depths in the sand. Page 8 Rocky shore. Tide changes twice a day bring in plankton, which are tiny microscopic plants, the basis of the food chain. Rock pools are natural aquaria left behind when the tide recedes and pools of sea water are left trapped between the rocks. These are home to any sea creature left stranded by the tide. Most of these animals must adapt to live in these pools which may dry up in the sun. They also need to avoid being eaten by predators such as seagulls. Most animals in the rock pool stay safe by having a shell which they can hide inside when the tide retreats and stay locked to the rock’s surface so that birds cannot get at their soft bodies. Limpets and winkles graze on algae found on the rock when the tide is in and are protected from drying out and from predators when the tide goes out. The rocks also provide a home for seaweed holds fast to the rocks so as not to get washed away. Once the tide is out shore crabs hide beneath the seaweed looking for food to eat. Crabs have a protective shell, exoskeleton, around their whole body as well as claws to defend themselves. All these animals wait for the tide to cover them so that they can breathe the oxygen in the water and also eat. Sand dunes. The sand dunes contain a number of different areas formed by a process called succession. This variety of areas supports a remarkable range of plants and animals. The dune slacks, for example, support large numbers of orchids in spring and early summer. Grey dunes Fore dunes Embryo dunes Dune slack Dune grassland Dune slack Woodland Sea Formation of sand dunes. • The sand moves until it meets a slight obstruction, such as a clump of grass, which deflects the wind and allows the sand grains to drop • Thus a slight mound or hummock is created • Wind moves sand up to the top of the pile until the pile is so steep it collapses under its own weight and falls down the leeward side called the slip face • The collapsing sand comes to rest when it reaches just the right incline angle to keep the dune stable • This angle is called the angle of repose and is usually 30-34 degrees Scientific studies have demonstrated that Marram Grass can die if walked over 10 times. Page • 9 The embryo and fore dunes. The embryo dunes are directly behind the beach and the sand here is very unstable and constantly blown by the wind or falls down the dunes by gravity. These dunes build up to become larger fore dunes inland of the embryo dunes. Plants such as marram grass are adapted to live in these conditions by growing through the sand when they are buried and by having very long roots to access the water deep under the dunes. Their leaves are also rolled so that they do not lose much fresh water. • • Marram roots can grow up to 7cm in 10 days. Marram can survive when buried by 1 metre of sand per year. When it rains on the fore dunes it very quickly soaks down into the sand too deep for most normal plant roots to reach. Some plants found here look more like cacti with fleshy leaves which hold onto fresh water, e.g. Sea sandwort. At Oxwich NNR the embryo dunes are being destroyed by visitors and are only properly forming at the far end of the beach by Nicholaston Pill. The dune slack. Behind the fore dunes the surface of the sand dips down to below the water table, i.e. where the underground fresh water lies. This makes the area much wetter than the surrounding dunes. In winter the slack can even flood to form a pond. Plants that live here are different from those on the dunes because they are not adapted to living in dry areas. Creeping willow is found in abundance here and is a much larger woody shrub than the plants found on the rest of the dunes. Red poplar leaf beetles (they look like large ladybirds with no spots) can be found feeding on the willow leaves and the common lizard favours this lush, damp habitat, which provides them with food in the form of invertebrates, shelter, warmth and fresh water. The grey dunes. The largest dunes are found near the back of the dunes and have far less open sand. These have a layer of soil on top which holds the rain and makes it a damper and richer place for plants to live than the fore dunes. These dunes are much more stable and plants like marram grass grow only in small patches. Plants like mosses fill the gaps between other plants, e.g. stone crop and fescue grass. These dunes are less exposed to wind and the plants do not have to be so well adapted to drought to live here. Dune grassland. Inland of the dunes lies a dune grassland. This looks very similar to normal grassland or field, but there is still a lot of sand beneath the thin layer of soil. The soil has changed as you more inland and what started as an alkali soil is slightly acid. The variety of plants that grow here is large and if the area is not grazed or mowed shrubs and then trees will grow here and it will become a woodland. Plants such as orchids, cowslips, and buttercups grow here and provide food for butterflies and bees. Page Reedbed. 10 Woodland. The climatic climax habitat, the final habitat at end of succession, of the sand dune system is a woodland. At this point in succession the habitat has reached a steady state and the conditions are less variable and more stable. The woodland inland of Oxwich sand dune is not very large because there is a freshwater marsh and reedbed where it would be otherwise. The wooded cliffs are composed mainly of oak and ash, but also include wild service trees and wych elm. The trees found in the woodland are elm, sycamore, oak, birch, and ash. Inland of the woodland at Oxwich NNR lies an extensive reed bed. Species of plant to be found there are common reed, yellow iris and bulrush. The main reed bed extends for some one hundred acres, making it one of the largest in Gower. The reeds make a perfect habitat for nesting birds. Large numbers of warblers come to breed in the springtime, cetti’s warblers, reed warblers and bitterns. Otters also visit and swim in the area of open freshwater. Freshwater marsh. The freshwater marsh is made up of a raft of Sphagnum (bog) moss floating on six foot of fresh water. It is a very dangerous place to visit since there are gaps in the moss which are in open water. Bog moss acts like a sponge and soaks up as much as 20 times its own weight in water, thus helping to keep the bog surface wet. The marsh has no soil so all the plants living there grow on top of the moss and when the moss dies more grows on top of it. The plant absorbs all the nutrients found in rainfall by exchanging them for hydrogen ions. Hydrogen ions are acidic and they help to increase the acidity of the water on the bog. Pond. Within the freshwater marsh lie areas of open water. These ponds are home to a whole range of aquatic animals such as waterboatmen, damselfly nymphs, (juveniles), frogs and newts. Their depth varies and are usually covered in vegetation which provides food and shelter for the animals living there. Page 11 Saltmarsh. By Nicholaston Pill the sea covers the rivers banks and adds salt and mud to the habitat on either side of the river. These saltmarshes contain species of plants which can tolerate being covered with salt water. Plants found here include Sea Lavender and Sea Puslane. These are adapted to the conditions found in the saltmarsh are usually fleshy like cacti so that they do not get dehydrated, (loose freshwater), by the salt water. Oxwich saltmarsh is not a very suitable place for data collection as the sea does not cover it very often so it does not have all the plants and animals you would expect in a saltmarsh.

Follow Code of Good Practice for Field Study Visits. Page 16 Additional notes: Page 17 Safe field techniques Code of Good Practice for Field Study Visits. Know the Site. The visit leader, whether an independent provider or a teacher, should know the site well and be aware of any risks and know how to deal with them. Read site specifications, talk to the landowner, visit the site in advance and prepare a risk assessment. Be aware that some sites are not suitable in certain weather conditions or at certain times of day year e.g. rock pooling at high tide, fresh water marsh after very wet weather. Liaise with the landowner Seek permission if you plan to leave footpaths, carry out any activities other than walking or leave semi-permanent devices. If you spot hazards or anything that concerns you, or if your students produce good data, let the landowner or site manager know. Oxwich is owned by Countryside Council for Wales, contact details in Appendix C. Be prepared Ensure that visit leaders are suitably qualified and trained and make sure that emergency procedures, site permissions, adult to pupil ratios and parental consents are in place. Prepare alternative activities and routes in case of unexpected changes and take emergency contact details, a charged mobile phone, spare clothes and extra drink and food. Leave as you find Always leave habitats as you find them: put animals, rocks, logs, etc. back in their exact locations; take care not to damage pond banks when carrying out pond dipping, etc. Be aware that many species are protected by law and should never be picked up or removed from site, if you are unsure do not pick up or remove. Where taking samples is permitted, these should be limited and, where appropriate, returned. Be Green Encourage awareness of wider environmental impacts; consider the mode of transport you use, remove and, if possible, recycle litter found and waste created. Page If you are unsure or require extra guidance in undertaking field study visits contact the site warden who will be able to advise you or provide a guided tour of the site. 18 Follow the Countryside Code • Be safe, plan ahead and follow any signs • Leave gates and property as you find them • Protect plants and animals and take your litter home • Keep dogs under close control • Consider other people Scheme of Work Lessons to prepare and undertake educational visits at Oxwich NNR, focusing on planning an investigation.

Activities Prior to the field visit students in the class design a route through the sand dunes to visit various interesting aspects such as all the habitats. Measure the distance on the map along the route. In the field students each has a map which they orientate . Following the map they need to walk to the highest sand dune they can see. On top of the sand dune use the panorama photo sheet and the map of local area to label the landscape features that they can see. Follow your route through the sand dunes and use pacing to measure the actual distance. Or, Learn how to use a compass and follow the compass trail for Oxwich NNR. Find an open space and create a grid to teach grid references with numbered corks and tape measures. Play battleships. Prior to the visit create questionnaires to see how far visitors have come to visit Oxwich NNR. Interview people by the car park, on the beach and in the sand dunes. See how far they have travelled and where they have visited in the reserve. Count the number of visitors as you walk along your route through the sand dunes. Compare your measured route distance to your route on the map. How similar are they? Write an account of your walk through the sand dunes and link the description to the location on the map. Discuss how easy it was to follow the map in the field. Why was it harder/easier than you thought? Graph your visitor questionnaire results.

Draw a graph showing the relationship between distance from car park and number of visitors. Is there a pattern in the results. Can you explain the pattern? Learn how to use a compass and describe the route you took on your trip with compass bearings and distances, e.g. start from the far North East corner of the car park. Travel 100m on a bearing of 280 (NE). Stop at the information point. Art - To use the environment at Oxwich NNR to find different colours and inspire creativity. Create art using objects found in the environment. Create an artist’s pallet using samples of colours from the reserve. Create your own paints using the plants of the reserve. From on top of a high sand dune an overview of the landscape is explained so that the pupils can draw an outline of the landscape.

Find objects with different textures. Experiment with making rubbings of them. Collect items from the strand line for a hanging mobile. Create a whole class piece of art by drawing a circle and each student builds a small sculpture around the outside of the circle. 33 They should use a variety of materials e.g. sustainable materials. Page pollination. Undertake an investigation into which colour insects like best. Look at the camouflage colours of the animals found in the sand dunes, compare them to the plant and environment colour. Place sheets of different coloured paper outside in the sun. Cut some into different shapes including flower shapes. Count how many insects visit each colour in 10 minutes. Is there a pattern? Create your own camouflage creature and hide it in the school grounds. Use the colours found within the school ground to inspire painting. Repeat the paint pallet and compare the different colours from the different locations. Create sculptures out of objects found in the school grounds, e.g. twigs, leaves, mud, stones. Make mobiles using willow circles to dangle objects found around the grounds. Create a huge piece of art on the school field which can be seen from a distance using flour, chalk or small stones or shells. Look up Andy Goldsworthy on the internet and use his designs to inspire creativity in the class. Create a sculpture trail in the school grounds with sculptures hidden along the way. Label the sculptures or create a visitor’s guide to the sculpture trail. Create a texture hunt. The class takes rubbings of a number of objects located around the school, e.g. bark, leaves, plaques. The rubbings are numbered and another class must try to find where all the rubbing came from by making their own rubbings. Page 34 Detailed lesson plans for specified field days at Oxwich NNR. Lesson 9: Scientific investigation and geographical enquiry field day. Aim: To gather data from at least two habitats to enable a comparison of the organisms living within them. Hypothesis: What is the difference between the animals and plants living in the different habitats at Oxwich NNR? This field day can be the culmination of the first 8 pre- visit scheme of work lessons. These involve the completion of the worksheet “My investigation at Oxwich NNR “ prior to the visit to plan the investigation. Choose two or more habitats from the list of habitats found in Oxwich NNR. Terrestrial Habitats: Sandy shore Strandline Sand dune Meadow Grassland Woodland Freshwater marsh* Not suitable for data collection at Oxwich. Salt marsh* Not suitable for data collection at Oxwich. Aquatic habitat: Pond Marine habitat: Rock pool Research each habitat and use the information you have found to fill in the investigation sheet in class before you arrive at Oxwich NNR. Use the map to locate a site for data collection for each of your habitats. A group size of two or three would be best, taking it in turns to write the data down and look and count. How to undertake fieldwork countryside Council for Wales Page Method for terrestrial habitats. 1. Place four bamboo canes in a square in one of the habitats. 1m x1m bamboo canes are suitable for all the terrestrial habitats except the woodland. For the woodland lie 5m X 5m tape measures on the ground for the trees and use the 1m2 bamboo canes for the undergrowth. 2. Count the number of different plants in the square and fill in the data collection sheet of the diversity and key species. 3. Catch any animals, (mini beasts) found in the square and write down the number of different animals and the key species. 4. Do this a number of times, say 10 times. 35 At each of the habitats collect data on the animals and plants found in each using the investigation data collecting sheet on page 43 – 46. Oxwich NNR 5. Identify what you have caught and count the number of different specimens and name the key species. Use the animal identification guide found in the appendix. 6. Walk to your next habitat and repeat the process. To reduce the need to carry excessive equipment larger group sizes are needed. Also the room around the pond is limited. Pond dipping could be done either side of the boardwalk if there is a lot of water in the marsh. Make sure all dippers lie down. One bucket per 5 children. Method for aquatic habitat. 1. Fill a bowl with pond water. 2. Lie down on the bank with a net. Sweep the net just under the water’s surface in a horizontal figure of eight, motion. 3. Make four sweeps of the same length. 4. Empty the net into the bowl of water. Try the sweep again, but this time in open water away from the pond plants. 5. Sort out the mini beasts catching them with a white spoon and a paintbrush. Treat all living creatures with respect, please be gentle! 6. Identify what you have caught and count the number of different specimens and name the key species. Use the Pond Survey worksheet and Pond ID guide that can be found on pages 55 and 55 and in the appendix. ∞ Children can work in pairs of larger groups, keep the class close, set clear boundaries and ensure they know what the return call is. Method for marine habitat: Rocky shore. 1. Fill a bucket with sea water. 2. Find a suitable rock pool and search within the pool, under the rocks and hanging on the rocks for animals and plants. 3. Identify what you have caught and count the number of different specimens and name the key species. Use the rock pool animal identification guide in the appendix.

Page Name of animal Oxwich NNR Investigating microclimate/environmental factors. Aim: Measure the different environmental conditions found within each habitat to identify why the habitats differ. Groups of 5 or 6 can be accommodated as each student can undertake a different measurement. If the children have created their own meters then they can all do the readings at the same time. Groups may be limited by the amount of equipment such as thermometers. Method: Microclimate can be measured in a number of habitats and compared. Microclimate along a transect, from the front of the dunes to the woodland ,can also be investigated. Factors to measure: Air temperature – Affected by degree of shading from trees. Wind speed – Affected by vegetation and landscape, such as hills. Humidity – Affected by amount of vegetation and moisture in the air or locally, e.g . pond. Soil temperature – Affected by degree of exposure to sunlight and shading. Soil texture – Affected by amount of sand and organic matter. Soil pH – Affected by amount of organic matter. Water content of the soil – Affected by the amount of sand in the soil and organic matter. Organic content – Affected by amount of vegetation. Infiltration rate – Affected by the amount of sand and organic matter. How to undertake fieldwork countryside Council for Wales Page Wind speed – Using a wind meter, take wind speed at arms length above head or at ground or vegetation height. Humidity –Wet the cloth of the wet bulb on the whirling hygrometer swing above head for a minute. Read off the two readings from the dry and wet thermometer. Use chart to work out % humidity . Soil temperature – Place thermometer on surface of soil or 5cm down into the soil. Leave to settle before reading. Soil texture – take a sample of soil and moisten. Use soil texture sheet to work out texture. Soil pH – Mix soil with distilled water and Barium sulphate to settle soil. Add indicator solution and wait for colour change. Water content of the soil – Use a moisture probe or collect a sample, weigh it then place in a cool oven, 1000C. Once dry reweigh and work out the % water content using this equation. Weight loss from drying X100 Fresh soil weight Organic content – Using the soil you have dried in an oven weigh the soil then place in a hot oven until all the organic matter is burnt off. Infiltration rate – Place into the soil a can open at both ends as deep as it will go. Fill the can with 100ml of water and time how long it takes for the water to be absorbed into the ground. 60 Methods: Each factor can be measured in different habitats by each group filling in the worksheet on page 58. Or a transect, line, from the beach to the back of the dunes, can be walked with measurement taken at each different microclimate using sheet on page 60. Oxwich NNR Equipment: Thermometer or temperature probe. Soil thermometer, (a thermometer in aluminium case) Hygrometer, (measures humidity) Universal indicator solution, or pH meter, Distilled water, Barium Sulphate, Pot, A tin can open at both ends, Measuring jug, Stop watch, Wind meter or homemade wind gauge, or windmill. Soil texture card, Access to an oven, Weighing scales. Each factor can be measured using low tech equipment or it may be estimated. As long as a difference between the two habitats can be observed an absolute value is not necessary. Post visit work: Page 61 Look at the data the class has collected and describe and explain any patterns in the data. Is there a difference between the micro climate or soil in the different habitats? Draw graphs to show these differences visually – bar graphs are best, kite graphs are very good but a bit beyond KS2. Graph each variable you measured in both the habitats so you can compare the results. Discuss why conditions are different in the two habitats and try to explain the measurement found with the observation made in the habitats. Evaluate you fieldwork. What was difficult? What was easy? What would you change? Are your results reliable? What other fieldwork could you do in the future at Oxwich which would support your data?

Aim: To discover the feeding relationships found in the different habitats. Small groups of 2 or 3 for collecting animals, or a whole class can work together to create one big food web with all the children being animals and wool being held by each to show links. Method: Visit a number of different habitats and collect the animals living there either in pots or through visual observation, e.g. birds, faeces, tracks. In each habitat write down the animals you have found. Method for grassland. 1. In grassland find an area with tall grass but few spiky plants like bramble, which snag on the nets. 2. Spread out and allow the children to walk through the long grass sweeping the net from side to side in front of them as they walk. 3. Stop and look into the net to see what you have caught. The flies will fly off so try to close the net and stop them. 4. Encourage any large animals to crawl into a pot so that they can be identified using the ID guides. 5. Put the animals back in the grass and let your partner have a go. 6. Do not leave animals in pots for too long as they will die. Method for and woodland. 1. Find a tree with very hanging branches or one branch with hangs low. 2. Spread out a double bed sheet and have the class all hold it out straight, like a parachute. 3. The children may want to put hoods up if they are standing under the tree. 4. Manoeuvre the class until the sheet is directly below the branch. 5. On the count of 3 shake the branch very vigorously for as long as you can. 6. Keep the sheet still and see what animals you have caught. 7. Let them crawl into pots if they need identifying. Method for aquatic habitat. 1. Fill a bowl with pond water. 2. Lie down on the bank with a net. Sweep the net just under the water’s surface in a horizontal figure of eight, motion. 3. Make four sweeps of the same length. 4. Empty the net into the bowl of water. Try the sweep again, but this time in open water away from the pond plants. 5. Sort out the mini beasts catching them with a white spoon and a paintbrush. Treat all living creatures with respect, please be gentle! 6. Identify what you have caught and count the number of different specimens and name the key species. ∞ Page 65 Method for marine habitat: 1. Fill a bucket with sea water. How to undertake fieldwork countryside Council for Wales Oxwich NNR 2. Find a suitable rock pool and search within the pool, under the rocks, under seaweed and hanging on the rocks for animals. Using the animals found within the different habitats create food chains and webs. In the field give out picture cads of each of the animals you have found today. Use the information on the card to create a food chain in small groups. Link the animals together using wool and clothes pegs. Try to join all the chains together to make a food web. Use wool in the field and create a huge food web connecting a number of habitat’s species together. You can use the pictures from the identification guides or cards, or children just name animals they have found on the site. Place one person in the middle of the circle. They are the tree. Everyone in the circle chooses an animal they have seen today. Give the tree some wool and see if you can connect each animal to the tree and to each other. You can add non living things also like water and sunlight. Get the tree to pull on all its strings to see who will be affected if something happens to the tree. Once everyone has felt the pull cut the tree down, or take away all the water and see what happens to the food web. Once it has collapsed allow the children to put pressure on the left over resources by pulling the wool out until it snaps. Make sure the children do not tie the wool around their fingers only hold the wool, and use wool as it will break. Equipment: Terrestrial habitat. 1. Data collection sheet – 1 per person. 2.

Aim: To discuss the threats to Oxwich NNR and try to arrive at some solutions. Method: Find a footpath close to the car park and close to the beach. Measure the width of the footpath. • Choose a 50 metre stretch of footpath. Divide a class of 30 into 5 groups. Each group will need a set of equipment. Space groups out at equal intervals along the footpath. • Using a tape measure, measure width of footpath and mark out 2 metres on either side of the footpath to form a transect, (a transect is a line along which you take measurements), across the footpath. • Place the quadrat at 5 points on the transect - in the middle of the footpath, at the footpath edges and both ends of the transect. At each point measure the vegetation height and vegetation cover (how much of the quadrat is covered in plants). Fill in the worksheet “Human impact on Oxwich NNR, data collection sheet“ on page 72. Transect Path edges Left end of transect Left edge of path Middle of path Right edge of path Right end of transect Find another footpath close to the first one which is covered in cockle shells. Measure the width of the footpath. Walk away from the car park along the front of the dunes. Every 5 minutes stop and measure the width of the path. Complete the worksheet on footpath erosion page 71. At the same time another group within the class counts the amount of litter in the area and another group the number of visitors in the area. When you reach the furthest point from the car park, before you turn back repeat the transects. On your way back take a walk around the reserve and jot down on the collection sheet the threats to Oxwich NNR which you observe. How to undertake fieldwork countryside Council for Wales Oxwich NNR Page Post visit work: Individual groups report on their findings and complete a master data sheet Draw bar graphs to represent the data. X axis distance from car park Y axis % of vegetation cover, height of vegetation categories. Bar graphs can also be drawn for the footpath width, litter and visitors. A scatter graph could be draw to show the relationship between footpath width and number of visitors, or number of visitors and amount of litter. Discuss what patterns the graph shows. What do the results show? Why is the pattern like this? Why do you think this pattern exists? How could the footpath be improved to be made more sustainable? Design a poster informing visitors to Oxwich of the threats their actions may have to the reserve and how they can help protect it. 73 Equipment: Tape measures – 1 per group.

Aim: To use the environment at Oxwich NNR to find different colours and inspire creativity. The class can work individually or in small groups. Method: Distribute small pieces of card with double sided sticky tape on. Peel off and see how many colours you can collect. Only take very small samples of each colour and be careful not to harm the plants, especially the orchids. Create your own paints using the plants of the reserve. Pick a sample screw it up into a ball and then rub the plant onto some paper until the colour is transferred. Try to find different shades of green – (grass), black – (charcoal), yellow – (dandelion) , pink – (valerian) . BE AWARE that there are some prickly plants – dewberry – looks like bramble, Sea holly – looks like holly. Sea spurge has a nasty latex inside it that can irritate the skin. From on top of a high sand dune an overview of the landscape is explained so that the pupils can draw an outline of the landscape. The students record the colours of the various parts of the view for later watercolour work back at school. Alternatively colour the picture using natural paints. Invertebrates can be caught and their colours recorded for later use looking at pollination and adaptation. On the beach make sculptures. These could be of creatures you have seen on the beach such as crabs or mermaids. Work in groups and allow the groups to create half the sculpture and then swop over and the other team finish the sculpture. Find objects with different textures. Experiment with making rubbings of them. Try to guess the object from the rubbing. Collect items from the strand line for a hanging mobile. Tie string to a piece of driftwood and collect shells with holes in, seaweed and other objects. BE AWARE that sharp objects can be washed up. Try to only collect natural objects. 77 Create a whole class piece of art by drawing a circle and each student builds a small sculpture around the outside of the circle. It could be a pile of stones cemented together by sand, or a pattern made by different coloured stones or shells. How to undertake fieldwork countryside Council for Wales Page Equipment: Cards with double sided sticky tape on. Oxwich NNR Pencils. Paper. String. Pots. Colours Page 78 Post visit work: Colour the outline of the landscape created on the dunes using watercolours. Look at the colours of the insects you found, is there a pattern? Is there a relationship between the insect’s colour and where it was found? Investigate the relationship between plant colour and pollination. Undertake an investigation into which colour insects like best. Look at the camouflage colours of the animals found in the sand dunes, compare them to the plant and environment colour. Place sheets of different coloured paper outside in the sun. Cut some into different shapes including flower shapes. Count how many insects visit each colour in 10 minutes. Is there a pattern? Create your own camouflage creature and hide it in the school grounds. Use the colours found within the school ground to inspire painting. Repeat the paint pallet and compare the different colours from the different locations. Create sculptures out of objects found in the school grounds, e.g. twigs, leaves, mud, stones. Make mobiles using willow circles to dangle objects found around the grounds. Create a huge piece of art on the school field which can be seen from a distance using flour, chalk or small stones or shells. Look up Andy Goldsworthy on the internet and use his designs to inspire creativity in the class. Create a sculpture trail in the school grounds with sculptures hidden along the way. Label the sculptures or create a visitor’s guide to the sculpture trail. Create a texture hunt. The class takes rubbings of a number of objects located around the school, e.g. bark, leaves, plaques. The rubbings are numbered and another class must try to find where all the rubbing came from by making their own rubbings. How to undertake fieldwork countryside Council for Wales Oxwich NNR Geography at Oxwich NNR. Aim: To experience using and following a map and to calculate distances. Use of co-ordinates and four-figure references. Method: Prior to the field visit students in the class design a route through the sand dunes to visit various interesting aspects such as all the habitats. Measure the distance on the map along the route. In the field students each has a map which they orientate . Following the map they need to walk to the highest sand dune they can see. On top of the sand dune use the panorama photo sheet and the map of local area to label the landscape features that they can see. Follow your route through the sand dunes and use pacing to measure the actual distance. Or, Learn how to use a compass and follow the compass trail for Oxwich NNR. Find an open space and create a grid to teach grid references with numbered corks and tape measures. Play battleships. Prior to the visit create questionnaires to see how far visitors have come to visit Oxwich NNR. Interview people by the car park, on the beach and in the sand dunes. See how far they have travelled and where they have visited in the reserve. Count the number of visitors as you walk along your route through the sand dunes. Equipment: Map of Oxwich – 1 per student, Either OS map or drawn map, pages 80 –84. OS map of surrounding area. Ruler – 1 per student. Compass – optional. Panorama photo sheets – page 78. Numbered corks 0 – 10 X 2 Two 10m tape measures. Questionnaires. Risk assessment: When interviewing visitors ensure the children work in groups and a teacher is always close by. Also try to undertake interviews when visitor numbers are high so that the class is less intimidating to a small number of visitors. How to undertake fieldwork countryside Council for Wales Oxwich NNR Page 79 Post visit work: Compare your measured route distance to your route on the map. How similar are they? Discuss how easy it was to follow the map in the field. Why was it harder/easier than you thought? Write an account of your walk through the sand dunes and link the description to the location on the map. Make your own version of a map of Oxwich and key. Add the photos you took on the field trip to the map. Make a movie in “movie maker” of the photos of the sites you visited on Oxwich NNR. Add a soundtrack of the children narrating the day. Create a visitor’s guide to Oxwich NNR with a map and details of places to visit on the reserve. Graph your visitor questionnaire results. Bar graph or pie chart of distance visitors have travelled. Line graph of distance travelled and where they have visited on the reserve. Is there any pattern in the results? Draw a graph showing the relationship between distance from car park and number of visitors. Is there a pattern in the results. Can you explain the pattern? Compass trail for Oxwich NNR. 1. Start from the far northeast corner of the car park. 2. Travel 100m on a bearing of 280 (NE). Stop at the information point. 3.
