Teacher guide to Namoi ‘special place’ Visiting the site Site 4: Quipolly Dam, Werris Creek, Quirindi This document provides information for an excursion to Quipolly Dam. It covers safety aspects, getting to the location, accessing the trail through the reserve, and the stopping points for various activities. The activities and associated tasks given here are included in the education package; all the tasks to be undertaken during a visit to a site are suitable for inclusion in a field trip to Quipolly Dam ‘special place’. 4.1 Safety in the bush Safety concerns for Quipolly Dam, and potential remedies, are listed in Table 4.1. Table 4.1 Potential hazards and remedies Potential hazard Traffic (where activities are undertaken close to the road) Drowning (some stops are near a large body of water) Snake bite Biting and stinging insects Prickly pear and tiger pear Falling branches Trips and falls Sun exposure Dehydration Remedy Exercise caution near roads Be alert near the dam edge and spillway Bandages and first aid knowledge Anti-bite cream Antiseptic cream Exercise caution during windy periods First aid kit Sun protection (e.g. hats, sunscreen) Carry sufficient water Wear appropriate clothing for the excursion. Wearing proper footwear and long pants in the bush lessens the chance of injury from bites and falls, and can even help to limit the amount of venom entering your body if you are bitten by a snake. Quipolly Dam provides drinking water to Werris Creek; therefore, it is covered by a drinking water risk management plan, to prevent contamination. Various activities are prohibited at the dam (including swimming and camping) to help preserve the water quality. Please ensure that 1 no one enters the water or disposes of any garbage into the dam: this could be your drinking water! 4.2 Tracking, travel and amenities Tracking Download the Quipolly Dam.kmz file to your smart device (see Task 1.1 in Activity 1 for instructions on using Google Earth). Use your smart device to track your location as you travel through the area and undertake the activities (the Quipolly Dam.kmz file includes relevant map locations). When you set out, set the device to locate your position. On the journey, pass the device to a student and ask the student to navigate to your first stop. Internet access is available for most of the locations; however, a black spot where no service is available may affect the sites around Stop 3, or is at least likely to be a problem when moving between Stops 1–3 and Stops 3–4 (Fig. 4.1). Take a hand-held GPS with the latitude and longitude of the various stopping points installed, and a printed copy of this document on the field trip. Refer to Table 4.2 for information about stops, points of interest (POIs) and suggested activities or tasks. Figure 4.1 Mobile phone coverage for Quipolly Dam The pin indicates the position of Stop 1, and the white area indicates where there is no service for part of the ‘special place’ study area. Directions and parking From Quirindi High School, drive 10.5 km north on the Borah Creek Road to Lowes Creek Road junction (or, from Werris Creek, drive south on Werris Creek Road for about 15 km, turning left onto Lowes Creek Road and continuing on to the Borah Creek Road junction). Continue east along Lowes Creek Road past the old Quipolly Dam to reach the first stop (Fig. 4.2). Lowes Creek Road is an unsealed road that can accommodate traffic in both directions, but take care when passing oncoming traffic. Stops 1–4 (past old Quipolly Dam) – continue along Lowes Creek Road (from the Borah Creek Road junction) for about 4 km east of the junction between Borah Creek Road and Lowes Creek Road (just past the Whispering Pines Bush Retreat). The bus can park on the verge, or the northern side of the track near the stops. Stop 5 – head south along Lowes Creek Road to the new Quipolly Dam. 2 Return to Quirindi via Borah Creek Road, or include optional Stop 6 and POI13 by returning along Lowes Creek Road and then to Quirindi via Werris Creek Road (~ 16 km). Figure 4.2 Google map directions to Quipolly Dam sites (A = Quirindi, C = new Quipolly Dam, B = Stop 1). Parking for Stops 1, 2 and 4 is on the verge of the road or off road on the track. A parking and pick-up point is available at Stop 3. Parking for Stop 5 is available at the new Quipolly Dam amenities area. Amenities Toilets and picnic shelter (Fig. 4.2) are available about 400 m east of the new Quipolly Dam wall. Figure 4.3. New Quipolly Dam amenities 4.3 Undertaking activities At each stop or POI, check your position on your smart device or printed copy. 3 Table 4.2 Quipolly Dam stops and points of interest Stop (S) or point of interest (POI) Location Activity or task S1 Parking area – off road on side track, just past Whispering Pines Bush Retreat. Pull off the road onto the verge at the location marked on the map, or park off road on the dirt track near the transect stop; check your position on your smart device or printed copy. Stop 1 – walk to transect area. S2a S2b Drive to the furthest stop to the east of old Quipolly Dam. The GPS waypoints provided locate the white pegs for the beginning and end of each of the transects: Begin Transect 1 (peg) End Transect 1 (peg). Using the GPS or printed map, walk west through the bush, parallel to the creek and road for 0.8 km (not on the road). Identify and record native plants, weeds, traditional use Aboriginal plants, animal scats and habitat. Meet the bus at the road at Stop 3. Walk west of the transect site to POI2 (use your smart device or printed map). POI2 Quipolly Creek Continue walking west to POI3 and POI4. POI3 Dense white cypress pine POI4 Walking track to creek POI5 Quipolly Creek Optional bus parking site, and pick up point. More active students can, if they wish, continue walking westward along the creek to the bird hide (~ 0.7 km) for continued observations. S3 POI6 Lowes Creek Road S4 Old Quipolly Dam, Lowes Creek Road Yellow box woodland Set up the transect between the posts. Use the surveying methods to determine the structure of the vegetation, and think about how the structure could change over time (as plants mature or if there is disturbance such as fire). Start activities: • 1 (Task 1.5) On this random • • • • • 2 (Task 2.2) 3 (Task 3.3) 4 (Tasks 4.2, 4.3) 5 (Tasks 5.2, 5.3) 6 (Task 6.5) meander, use the pictorial guides to identify and record key plants of the area, and record your findings in the Random meander observations datasheet. Look for labelled plants (blue = exotic, yellow = native). Possible site for Activity 7 (Tasks 7.3, 7.4); however, complete this activity before setting up any transects, to minimise disturbance. Answer Questions 4.1–4.3. General observation (plants are labelled): Grassy yellow box woodland, creek flat or riparian zone – riparian zone discussion. Mixed age trees, grassy with scattered shrubs. Look for weedy species here and mark them off in the Random meander observations datasheet. Discussion point – thick white cypress pine and a clear absence of an understorey. Answer Questions 4.4 and 4.5. Optional walk to weedy creek. Observe weedy creek line and dense white cypress pine regrowth. Potential pick-up point for end of Activity 1 (Task 1.5) random meander observations. General observation – weedy blackberry – dense growth that is difficult to eradicate. Optional stop – bird hide to view water birds. Look for the black swan, Australasian grebe, Eurasian coot and hardhead duck, as well as two ducks listed as vulnerable: the blue-billed duck and the 4 POI7 POI8 S5 POI9 Old Quipolly Dam wall Lowes Creek Road Lowes Creek Road Lowes Creek Road POI10 Lowes Creek Road POI11 Lowes Creek Road POI 12 Lowes Creek Road (wall of new Quipolly Dam) S6 POI13 Lowes Creek Road Lowes Creek Road freckled duck. Also keep an eye out for white-bellied sea-eagles; these are known to nest in the area of the old Quipolly Dam. General observation point. Thick white cypress pine – drive by observation. Toilet and picnic facilities – walk to dam wall from here. White box trees. Discussion point – coolatai grass invasion Note: do NOT walk through the grass – this is a listed weed and if you walk through it you may spread it. Examples of tumble-down red gum, white cypress pine and narrow-leaf ironbark (species that are likely to have been part of the flora of the surrounding area before it was cleared for agriculture); conglomerate rock here provides an example of Permian-Carboniferous geology. General observation point. Answer Question 4.6. Optional stop or drive by – shrubby white box woodland. Optional stop or drive by – coolatai grass invasion. Notes: The stops and points of interest are marked on the Google Earth file Quipolly Dam.kmz. Continue to use your smart device to track to your activity sites. Encourage students to discuss the importance of a riparian zone. Question 4.1: Does the riparian zone look healthy? (i.e. is there healthy vegetation, limited bare earth visible and few weeds?) Question 4.2: What is the quality of water in the creek? Question 4.3: Can you see any problems or issues at this section of the creek? For example: – Is there soil erosion along the creek edge? – Are there any indicators of flooding or fast moving water events in the past? (This will be shown by fallen trees, lots of smooth, rounded rocks and so on.) – Is the riparian zone weedy? (If so, the benefit of soil binding can be outweighed by the lack of diversity caused by the weed taking over an area and outcompeting native plants. Some water weeds can become so thick that waterways are choked – even to the point of inhibiting aquatic animals and plants that would naturally occur.) Question 4.4: What is the problem with limited or no ground cover? Answer: Soil erosion, which is especially a problem on slopes. Unlike the eucalypts and many native shrubs that have evolved with fire, cypress pine (as a conifer) is sensitive to fire. Question 4.5: What would happen if a fire went through and killed the cypress pines on the slopes? Answer: Fire is a complex topic but, put simply, fire-sensitive plants would be killed (including most weeds) and fire-adapted native plants (e.g. wattles, eucalypts, native peas and grasses) that have evolved with fire would regenerate more quickly. Many native plants with fire-adapted strategies benefit from fire. For example, mature wattle plants could be killed by fire; however, the wattle seeds will survive in the soil and germinate after fire. Eucalyptus trees have areas protected under the bark (lignotubers) that can re-sprout juvenile foliage if the canopy is damaged. The absence of fire favours regeneration of cypress pine, both species becoming dominant in areas across the north-west slopes that 5 were once cleared for grazing. Regrowth of white cypress pine becomes ‘locked up’, resulting in thick stands of stunted trees that inhibit understorey growth. Question 4.6: What can you do to help stop the spread of coolatai grass? Answer: Identify and report any sightings to your local council. Keep your vehicles clean to avoid seed dispersal. Teacher note: The control and management of weeds could be part of a post-activity discussion. 6
