Fuel reduction strategy

On Sunday 24th November Johno and I drove up the Trig Point track from Burgess Lane access from Boyes Road to Baranduda Regional Park. A fuel reduction burn had taken place in autumn 2012 on the high (southern) side of the track leaving the low (northern) side of the track unburnt.

On the ground the difference in vegetation was pronounced

It looks as if the burn off on the high side has resulted in more vigorous wallaby grass regrowth and flowering – and its tempting to conclude therefore making the fire risk worse. But the real purpose of the fuel reduction burn is to minimise the likelihood of a fire wicking up the loose and highly flammable bark on stringybark and to a lesser extent box trees potentially leading to a crown fire – upon examination of the blackened tree trunks in the photo below it would appear that this outcome has been achieved.

But the real purpose of the trip was to collect seed pods from the silky swainsona sericea plants we have been monitoring over the last 5 years. More about the outcome of that in the next blog entry.
