As reported in the Bega District News, this week the Forestry corporation and the OE&H released their long awaited final draft working plan, for the Murrah flora reserves.
According to the plan ” . . . The aim is that with the cessation of forestry and some specific management actions, koala recovery in the Murrah Flora Reserves and adjacent forest can be realised over time. This will be tested in the long term by monitoring and evaluation within an adaptive management framework.”
Regrettably, the OE&H’s adaptive management framework has some significant limitations. In particular the need to maintain the illusion, when prescriptions are followed, it regulates a sustainable logging industry. Hence the only referenced sentence on soils is ” . . . The steeper slopes are susceptible to erosion if disturbed (Tulau 1997).”
On forest condition the plan indicates ” . . . Mid storey structure and composition varies across the reserves, with a key management issue being the extent of black she-oak regrowth and other disturbance-generated tree and shrub species. These contribute to increased vertical fuel loads and prevent germination and regeneration of preferred koala species, particularly woollybutt.”
Another issue that could prevent the germination and regeneration of preferred koala species is soil loss and the associated reduction in soil fertility. For example, the harvesting plan for compartments 2080 and 2081, in Mumbulla SF and dated 11-8-1994, estimated an average of about 9.5 c/m of sawlogs and 85 tonnes of pulplogs per hectare would be removed in the operation. However, the estimated soil loss from the operation, only provided for cpt 2180, was 132.8 tonnes per hectare.
I recently revisited the vast area burned in the Cuttagee catchment, to get some shots of brown and dry vertical fuel loads, now some months after the fire. Coincidentally, I came across two of the recently established research plots. As indicated in the photo above, this one is on relatively flat ground. Some silvertop-ash and all the black she-oak have been cut down and placed into piles. Retained trees are mostly silertop-ash, a couple of spindly stringy-barks and a hickory wattle.Walking around the plot it was clear that all of the silver-top ash have coppiced, with multiple stems growing from the stumps. In addition there are dozens of hickory wattle seedlings in the plot. Both of these outcomes will increase vertical fuel loads, although unlike forest around the plot, these fuel loads won’t be brown and dry.
In the second plot below, on a steep slope, three large woollybuts have been retained during logging and it appears all of the regrowth trees were black-oak. These have been cut down and placed as one would make a bonfire. It appears attempts were made to burn the bonfire, although the timber was clearly too wet to burn. Hickory wattle seedling were also evident in this plot, although there were fewer than the first plot, perhaps due to erosion of the exposed soils.
Forestry and the OE&H are accepting comments on the plan until January 31, 2018.
