Teacher guide to Namoi ‘special place’ Visiting the site Site 1: Black Jack State Forest, Gunnedah This document provides information for an excursion to Black Jack State Forest. It covers safety aspects, getting to the location, accessing the trail through the reserve, and the stopping points for various activities. Choose some activities from the education package. Make sure you leave time for free exploring; all the tasks are suitable for inclusion in a field trip to Black Jack State Forest. 1.1 Safety in the bush Teachers will be required to undertake their own safety assessment for a class visit. Some safety concerns for Black Jack State Forest, and potential remedies, are listed in Table 1.1. Table 1.1 Potential hazards and remedies Potential hazard Traffic (where activities are undertaken close to the road) Snake bite Biting and stinging insects Prickly pear and tiger pear Falling branches Trips and falls Sun exposure Dehydration Remedy Exercise caution near roads Bandages Anti-bite cream Antiseptic cream, pliers Exercise caution during windy periods First aid kit Sun protection (e.g. hats, sunscreen) Carry plenty of water – none is available on site Wear appropriate clothing: wearing sturdy, preferably ankle-high shoes or boots and long pants in the bush lessens the chance of injury from bites and falls, and can even help limit the amount of venom entering the body in the event of snake bite. 1.2 Tracking, travel and amenities Download the Black Jack SF.kmz file to your smart device (see Task 1.1 in Activity 1 for instructions for using Google Earth). Use the smart device to track your location as you approach the site and undertake the activities (the Black Jack SF.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. 1 Internet access may not be available in all the locations at the site, so take a printed copy of this document on the field trip, and refer to Table 1.2 for information about stops (S), points of interest (POIs) and suggested activities or tasks. Directions and parking From Gunnedah, drive southwest on the Wandobah Road. Travel 3.8 km and turn left into Booloocooroo Road. After 2.2 km, turn left and travel east for about 1 km of unsealed road to the Black Jack State Forest gate (Fig. 1.1). Walk the 700 m to the survey area (Task 1.5 in Activity 1 can start here), or drive to the transect site if necessary. Figure 1.1. Google map of directions to drive from Gunnedah to Black Jack State Forest. Parking is available either at the gate, S1 or 700 m into the forest along the southern boundary (depending on conditions). Getting to the study site Two observation stops are included along the southern boundary of Black Jack State Forest. The first is located just inside the forest gate, and the main study site is about 700 m along the southern boundary. Check these locations on your smart device. 2 Amenities There are no amenities at this site. The closest public toilets are located within the Gunnedah Showground at the corner of Wandobah Road and South Street, on the southern outskirts of Gunnedah. Also, no water is available at Black Jack State Forest, so be sure to bring plenty with you. 1.3 Undertaking activities At each stop or POI, check your position on your smart device or printed copy. Table 1.2 Stop (S) or point of interest (POI) Black Jack State Forest stops and points of interest Location Activities and tasks S1 Black Jack State Forest Gate parking area; park here if walking in to survey site General discussion about weed invasion into the forest and answer Questions 1.1–1.3, below Start activities: • 1 (Task 1.5) random meander. Start completing the Random meander observation datasheet from Activity 1 – Record sheet; identify weeds and native plants using the pictorial guides and look for plants with labels (blue = exotic, yellow = native). • 6 (Task 6.6) from gate to transect site. POI1 Coolatai grass invading at gate into forest Stop and look at weeds. POI2 Mother of millions invading forest Stop and look at weeds; mother of millions was once a garden plant but is now a weed. POI3 Area of white cypress pine regrowth S2 If driving, pull off the track – this is the parking area for the main survey area; check your position on your smart device or printed map POI4 Scar tree Stop and look at the cypress regrowth, which is periodically managed by a thinning program. Over time, without thinning or fire the stand continues to thicken and the understorey vegetation layers will disappear. As a conifer, this pine is sensitive to fire, unlike the eucalypts and many shrubs that have evolved with fire; however, there is no evidence of fire at this ‘special place’. Answer Question 1.4, below. Potential site for Activity 7 (Tasks 7.3, 7.4). Continue activities: • 1 (Task 1.5) • 6 (Task 6.6) Potential site for Activity 7 (Tasks 7.3, 7.4); however, complete this activity before setting up any transects, to minimise disturbance. General observation and of scar tree. Contrast land management differences between Kamilaroi culture and European methods. 3 Stop (S) or point of interest (POI) Location S3a S3b The GPS waypoints provided locate the white pegs for the beginning and end of each of the transects: Transect 1 west end Transect 1 east end (The first transect position is about 50 m away, and the second about 100 m away from S2) S4a S4b Transect 2 east end Transect 2 west end POI15 Kangaroo grass area Activities and tasks Grassy white box woodland Set up the transect between the posts. Choose a survey method to determine whether this transect is grassy white box woodland or shrubby white box woodland, and think about how the structure could change between the two transects. Combined with the survey at S4, this activity allows you to see how the vegetation structure changes from shrubby to grassy woodland in the absence of fire (i.e. fire prevents the establishment of a shrubby layer by killing shrub seedlings and promoting the growth of native grasses). Discuss the importance of this area for the environmental services it provides to local landholders and the broader community. Start activities: • 4 (Tasks 4.2, 4.3) • 2 (Task 2.2) • 5 (Tasks 5.2, 5.3) • 3 (Tasks 3.3, 3.4) • 6 (Task 6.5). Shrubby white box woodland – see notes for S3 Continue activities: • 4 (Tasks 4.2, 4.3) • 2 (Task 2.2) • 5 (Tasks 5.2, 5.3) • 3 (Tasks 3.3, 3.4) • 6 (Task 6.5). Optional observation point Potential site for Activity 7 (Tasks 7.3, 7.4) Notes: The stops (S) and points of interest (POI) are marked on the Google Earth file Black Jack SF.kmz. Continue to use your smart device to track to the activity sites. Question 1.1: How might weeds disperse into the native vegetation? Answer: Wind, animals, vehicles and illegal dumping. Question 1.2: Where are most of the weeds concentrated and why? Answer: Weeds mostly occur along the edges of state forest boundaries. They are easily dispersed from disturbed areas that surround the forest, being deposited along tracks from vehicles, or illegally dumped along tracks or near the boundaries. Question 1.3: What can you do to help stop the spread of weeds? 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 discussion after the visit. Question 1.4: What would happen if a fire went through and killed the cypress pines on the slopes? Answer: Fire is a complex topic; however, put simply, fire-sensitive plants, including most weeds would be killed and fire-adapted native plants (e.g. wattles, eucalypts, native peas, grasses) that have evolved with fire would regenerate more quickly. 4 Question 1.5: What evidence is there that traditional Aboriginal life had a lower impact on the land than modern day land use methods? What was the key tool of the Aboriginal people? Answer: Scar trees are a result of where a traditional tool was harvested from a tree. The tree is left in place to continue to live to provide other environmental services, from shade to fire wood and even oxygen to breathe. Modern European land use contrasts greatly in that vegetation is removed or greatly altered to provide a landscape suitable for purposes such as agriculture. Aboriginal knowledge of the landscape, seasons and bush food provided tremendous advantage for survival. Teacher note: 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. The absence of fire favours regeneration of cypress pine and hop bush, both species that are becoming dominant in areas across the north-west slopes that were once cleared for grazing. White cypress pine regrowth becomes ‘locked up’, resulting in thick stands of stunted trees that inhibit understorey growth. 5
