After a bushfire there are a range of environmental impacts. Over time the landscape will recover (and some native plants actually need fire for their seeds to sprout) but some elements may need monitoring or some human help. Some links and information are provided below.
Post Bushfire Weed Control Program
Weeds are an expected environmental issue following a bushfire. The Shire is planning to purchase an aquatically approved herbicide for fire-affected property owners to use. Please read the Post Bushfire Weed Control Program information sheet prior to ordering.
Some native animals that were injured during the fire may not be found immediately. Take great care if handling any wildlife, and phone the WA Wildcare Helpline for advice if you are not sure what to do - phone 9474 9055.
Erosion and sediment control
Ground left bare after fire can be vulnerable to erosion. Soil and ash washing downhill can cause a lot of issues in dams and watercourses. There is more information on the impacts of the fire on water sources in the Shire's Health page
. The information sheet below lists some options to limit erosion and sediment problems.
Eastern States Wattles
If there were Eastern States Wattles nearby you may see a lot of their seedlings come up after the fire. They are easier to remove while they are young, before they grow into dense ‘thickets’. The Shire has a free booklet on local weeds called ‘Plants out of Place’ as well as a short guide to Eastern States Wattles.
Seedlings for Landcare
After a very hot fire, few plants survive and the seed bank in the soil may be depleted. If there are areas where you want to re-plant native seedlings (such as for creek or slope stabilisation) then a range of plants are available through the Shire’s annual Seedlings for Landcare program. Photos and information about most of the seedlings can be found in the Landscape and Revegetation Guidelines, also available as a printed book.
Local Flora and Bushlands
You may see some unusual plants appearing after the fire. They could be fire-sensitive orchids or other native plants – there is a free wildflower book available from the Shire to help identify them. If you are concerned that they are new or unusual weeds you can also use the MyPestGuide
service from the Department of Primary Industries and Regional Development (DPIRD).
Important habitat for native animals was lost in the fire, including large old habitat trees with hollows. Installing nest boxes is one way to quickly restore homes for hollow-dependent birds and other animals to nest. Boxes can be professionally made, part of a community program, or DIY – but different species have different needs.
Aboriginal Heritage Sites
Some areas or places are protected as significant cultural sites under the Aboriginal Heritage Act 1972. You need written approval for any work or disturbance within the boundary of a registered Aboriginal heritage site.
