The two arguments above have a rough parallel in ecology:
- Leaf litter is dangerous fuel which builds up and needs to be destroyed by burning.
- Leaf litter is important insect habitat, which reduces itself via invertebrate activity and natural decomposition. Burning destroys invertebrates and inhibits the process whereby litter turns into soil.
Which one of these is true? That’s a discussion we’d like to see.
In the mean time, one thing we can be sure of is that ecological concerns are not central to the practice of fuel reduction. Although managers have tried to be consultative on ecological effects in their burns, the fact that they are obliged to burn large areas prevents them from really engaging with ecological values. The Conversation article makes a point made many times before:
‘Early Australian colonists recorded many Australian forests as park-like with open understoreys.
‘This reflected First Nations’ care for country. In southwest Australia, as in many parts of the continent, Indigenous fire use was precise and focused. Unlike prescribed burns, Indigenous practitioners did not attempt to burn vast areas at once.’ (Fobif emphasis)
The upcoming Helge Track fire is 344 hectares. The adjacent Wewak Track block, due for burning next year, is 470 hectares. Together, that is a vast area of land in our region, probably the biggest area ever burnt in this way. We believe it’s impossible to look after ecological values in such an area.
