Hello Laurie and others,

A similar style of burning is probably required to maintain the native grasslands on the Nifold Plain of Lakefield National Park and Princess Charlotte Bay on the east coast of Cape York Peninsula (as well as other coastal grasslands on the Cape and around the gulf). Melaleucas appear to be steadily increasing in distribution on these grasslands. Queensland parks is well aware of the importance of this problem in Lakefield and they are attempting to manage it. I studied the finches in Lakefield NP and at Pormpuraaw (west coast of Cape) between 1998 and 2000.

These grasslands support Cape York Star Finches (N.r. clarescens), Pictorella Mannikins, Grass Owls, Red-backed and Red-chested Buttonquails among other things. The other important factor with the change in burning regimes in northern Australia is the change in grass species composition that has taken place in northern Australia. For example, the spread of Flinders Grass on Cape York which chokes out the native grasses which provide food for finches, parrots and quail.

John McAllister's explanation for how the grasslands existed before man's interference is very interesting and makes some sense to me. Of course, it doesn't help actually manage what is there now. We can't very easily go back to what the situation was before European interference.

Its probably also worth mentioning that for maximum retention of biodiversity you are going to require different fire regimes for different areas. What the CORRECT fire regime for a particular area is going to depend on which species you are looking to support or encourage and it is probably inevitable that you are going to disadvantage other species (whether on purpose or not). Not to mention the human safety and political reasons that have already been discussed. There may not be a perfect answer.

Cheers

Mick

From memory, they need periodic hot burns to stop the maleleucas taking over their environment, and to stop the butcherbirds picking them off at their nest hollows [in the termite mounds]

Regards, Laurie.

Hello all,

I recently read the report of the Golden-shouldered Parrot Recovery Team. a part of their explanation of the birds problems is very much related to lack of burning as well as lots of other things. for anyone interested in more on this burning debate it would be a worthwhile read.
