As reported by Sue Arnold in the Independent, the NSW Scientific Committee has rejected a nomination to list koalas around Port Stephens as an endangered population.
According to Sue ” . . . The Turnbull Government is overseeing a thoughtless extinction plan, dressed up as conservation, in which the koala will not survive.
While the Scientific committee’s determination acknowledges the population fits the criteria for listing as an endangered population. Under a previously unpublicised intergovernmental MOU this is now not possible, as per the following quote from the determination.
” . . . 18.Under clause 2.2 of the Intergovernmental memorandum of understanding relating to the agreement on a common assessment method for listing of threatened species and threatened ecological communities (CAM MOU 2015), a population of a species is not eligible to be listed as threatened if the species is separately listed as a threatened species under the Environment Protection and Biodiversity Conservation Act 1999.”
Probably not co-incidentally, the NSW and Federal governments are now seeking ” feedback on five-yearly implementation reviews of RFAs and how to extend them for an additional 20-year term.”
The website goes on to suggest ” . . . Consultation will enable a full appraisal of the current RFAs covering the Eden, North East and Southern regions of NSW. It will also drive optimal implementation of new agreements, including what we can learn from our experience over the past 20 years.”
Regrettably, personal experience suggests forests managers have learned very little at a regional scale and this appears to be the situation throughout NSW.
For koalas in the Murrah Flora Reserves, the major issue should be trying to keep trees alive. Unfortunately , along with the rest of the NSW government the OE&H and FCNSW have a blockage when it comes to what trees grow in – soils.
What they rely on is the less than current information, some of which is in the table above, from a paper, Forestry’s holy grail, titled Nutrient inputs from rainfall in NSW (Turner, Lambert and Knott, 1986). The fundamental argument in this paper is that virtually all the nutrients eucalyptus forests require fall with rain from the sky. So the loss of soil from erosion and dispersion won’t be an issue for hundreds of years.
Regrettably, this argument doesn’t really hold water, pardon the pun. The Calcium inputs from Mogo (4.2 kg haˉ¹ yrˉ¹), the closest station to the Murrah flora reserves, suggests 168 kgs of the nutrient would be deposited over a 40 year logging rotation. However a simple calculation for compartments logged in 1994, to be included in the reserve management plan comments, found around 1.4 tonnes of Calcium per hectare were likely to be removed or burned.
The replacement time for this volume Calcium from rainfall is 333.33 years. Of course this is before accounting for Sodium inputs, that counter the positive influence of calcium.
