Year 11 Geography Excursion to Hills Forest Discovery Centre

By Sarah Wayner

Recently the Year 11 Geography students went to Hills Forest Discovery Centre in Mundaring to investigate the scale of spatial impact that bushfires and phytophthora dieback can and do have upon our environments.

Each presents a significant natural and ecological hazard respectively, and both are highly relevant to our hills environment. We examined key factors that influence how these hazards spread and spent time mapping fire predictions for fires that have occurred in the Perth hills area. Students also spent time examining the challenges in reducing the spread of dieback and explored ways to mitigate against the devastation that dieback can bring to an ecosystem. A highlight of the day was injecting Jarrah trees with phosphite to provide a nutrient boost in an effort to stathe off dieback. This involved drilling a small 1cm hole on an angle, twisting the syringe into position and releasing the injection so that the tree through photosynthesis began drawing out the phosphite into its system.

A huge thank you goes to Mr C and Peter at Hills Forest Discovery Centre for their incredible knowledge and willingness to share their experiences with us.
