Fire & Biodiversity - One Positive Story.

The Swamp Bush-pea is listed as a rare species for Victoria. You wouldn’t think this to be so when so much of the plant is in flower at present within the Bunyip State Park – or at least in parts that were burnt in the fires on Black Saturday, 7th February 2009.

Undoubtedly, uncontrolled fire can eliminate a plant species from a local area. An invertebrate, herbivore or bird species that has some dependency on such a plant might also disappear or have its population severely depleted. Also undoubtedly, many native plants need a regime of fire to ensure their very survival. It seems Pultenaea weindorferi is one such species.

Apart from the pea flowering in such profusion on the Button Grass plain, a fellow ‘explorer’ just leaving as I arrived at the start of the walk the other day, reported seeing a Southern Emu-wren, a Beautiful Firetail and an Olive Whistler. I lucked out on all three. I just might try again soon.
