The NSW government has released its draft Coastal Integrated Forestry Operations Approval (IFOA) , being the protocols and conditions for coastal public forest logging, over the next 20 years. While there is a public consultation period, until 5pm 29 June 2018. I expect the draft is pretty well set in stone.
As I understand it the government believes it has a good understanding of koalas on the north coast. However on the south coast koalas are a ” . . . Threatened species requiring the development of site specific biodiversity conditions.” Of course the notion that conditions have to be developed is far too complex for Forestry Corporation, so surveys for koalas are only required in Glenbog and Glen Allen state forests in the Eden region. Both of these forests are on the tablelands and both are pretty well completely trashed.
In the Southern region, koalas surveys are required in Tallaganda, Badja, Dampier, Moruya, Wandella and Bodalla State Forests. As previously reported Dampier and Moruya state forests are where FCNSW has recently burned several thousand hectares. A request for detail ( compartment numbers) on the areas burned has been sent to Forestry, but there is, as yet, no response.
Researchers down in Victoria have been looking into the thermal qualities of man made and natural hollows used by native species.
The man made ones, generally constructed out of plywood, have been found to have poor thermal capacities. That is they get too cold in winter and too hot in summer. On the other hand, hollows in trees are far less variable, staying warmer in winter and cooler in summer. The researcher made some prototypes using a chainsaw.
So I had a try at making a little one, as indicated in the photo, from part of a smallish tree trunk that recently fell on the road. In essence it is a section of trunk cut length ways and a cavity is then cut into its center. A 3.5cm diameter hole provides access to the cavity, when the two pieces are screwed together. It is a relatively simple process, although best for those experienced in using a chainsaw.
