Manly Vale Public School upgrade threatens local extinction of endangered species

Manly Vale Public school is praised as being an innovative pioneer in regards to teaching their students the importance of the environment and sustainability. One of the reasons this school is able to to achieve such success in this area is because of its location. The school is located next to well kept remnant bushland which forms a linkage to Manly Dam Reserve which has further linkages that reach Garigal National Park and beyond. This unique setting allows students of Manly Vale Public School to immerse with the Australian wilderness and learn about the plants and animals which dwell there. This is a crucially important experience for children to have during their development. This enables them to form an early respect and understanding of the natural heritage of Australia, as well as a toolkit for survival and an early embodiment of adventure and joy of the wilderness.

Despite boasting being one of the few school in Sydney lucky enough to be surrounded by pristine Sydney sandstone woodland and being the forefront in primary education of sustainability, the department of education have decided to expand the school in a very unsustainable manner. Much of the  4.37 hectares of bushland proposed for “removal” will be on Department of Education land including the schools own “nature area”- used to teach generations of children about the environment. Clearing for the Asset Protection Zone requires compulsory acquisition of land into  Condover and Manly Dam Reserves. The latter being a living memorial to those who served in two world wars.

Now lets make this clear, I’m not against the expansion. I want this school to expand so it’s environmental education can reach more students. However, it can expand it’s facilities in a much more sustainable way. In this article I will describe what animals and plants of interest call this bushland-to-be-developed home and the inherent threats these species face.

The threatened Red-crowned Toadlet is the first in line to be completely wiped out from this area if this development proceeds. As I have described in the Backyard Conservation Fact Sheet for this species, the Red-crowned Toadlet is vulnerable to development which occurs on the ridge top above where they live. This is because Red-crowned Toadlets are always found on sandstone slopes in trickling tributaries and soaks. Development which occurs on the ridge top causes altered storm water regimes which always causes surplus of water discharges down these trickles and soaks which end up washing away the nests of these rare frogs.

Red-crowned Toadlets are usually only found in large reserves and national parks, so the fact that they are occurring in this comparatively small tract of bush next to Manly Vale Public School is a testament to how healthy and biodiverse this bush patch is. The proposed expansion of the school sees buildings to be constructed on the ridge above the known Red-crowned Toadlets populations and alarmingly close. These population will unfortunately be entirely extirpated from this bushland if the proposed development proceeds.

Eastern Pigmy Possum (Cercartetus nanus)

As with the Red-crowned Toadlets, the Eastern Pygmy Possum also faces local extinction if the current proposal is allowed to go through. The Eastern Pygmy Possum (the one depicted in the cover photo) is one of the smallest possums in the world and is just an adorable animal. Unfortunately often comes out second best in the face of urban expansion. In the case of Manly Vale, the remnant bushland next to the school appears to contain one of the most urban situated populations, which just further highlights how valuable and diverse this relatively small strip of bushland is. Experts have said that this population appears to be the remnant stronghold for pygmy possums in Manly Vale. Any further encroachment can and will eliminate pygmy possums from this area and surrounding areas.

Powerful Owl chick

Powerful Owl chick. These birds threatened and naturally rare. They are very picky in choosing their nesting hollow. Cutting down a chosen nesting tree will eliminate them from the surrounding landscape.

There are many more animals at threat  from the proposed expansion, including Bandicoots, Edichnas and Wallabies, but I have just touched on the threatened rare species. There has even been Powerful Owls found nesting on site. In addition to the threatened animals that face local extinction, there are also potential for threatened plants occurring on this site which also face annihilation. The plants include the Sunshine Wattle (Acacia terminalis spp. terminalis), Pimelea curviflora var. curviflora, Seaforth Mintbush (Prostanthera marifolia), and  Tetratheca glandulosa. This surprisingly diverse little bush hosts a wide array of many other  plants which once again highlight just how biodiverse it is. Thanks can be given to the hard working bush regeneration volunteers of this area which have labored thousands of hours keeping this bush clean and weed free. Unfortunately the proposed development would see all this work undone.

The fact is that there is enough space on school grounds which don’t contain bush to start development there. The proposed bush smashing can be undone with a smarter, more sustainable and less fragmenting development design. Any decrease in the destruction of Sydney sandstone woodland is huge in conserving the nature in Sydney as this biome is constantly under threat because it is situated in the most urbanised area of Australia. This is a very similar to a case to the Spring Gully threat. Both of these land clearances are proposed to be occurring within Sydney sandstone woodland, and in both instances we need to realise that we cannot negotiate the already limited pristine bushland within the Sydney region. There are always smarter and more sustainable ways of achieving development.

Overall we need to understand that we live in an age with an ever expanding population and thus very limited resources. Our strength is being the most intelligent species in the world. We need to use this intelligence and realise that unsustainable destruction of nature will only have negative compounding influences in the future. If the directors of the expansion of Manly Vale Public School can’t wake up and see just how unsustainable and unproductive the proposed development is, they will undo all the good work this school has been striving to achieve in the fronts of sustainability, the environment and the very future of the next generation of innovators and pioneers.
