Estimating the density of the Greater Glider in the Strathbogie Ranges

The report documenting the findings of the 2017 Strathbogie Forest Greater Glider surveys, conducted by DELWP’s Arthur Rylah Institute, has finally been released.

ARI report front cover

Main findings:

  • The Strathbogie Forest supports a large and regionally important population of Greater Gliders.
  • The Greater Glider population in the Strathbogie Forest has not suffered the declines that have occurred in the Central Highlands and East Gippsland, reinforcing the conservation importance of the Strathbogie Forest population.
  • Government data shows that many parts of the Strathbogie Forest support Greater Glider numbers that exceed the high-density threshold that would lead to forest protection in other parts of the state.

Summary of results (in italics):

  • Greater Glider population in Strathbogie Forest is ca. 70,000 individuals.
  • The detectability of individual Greater Gliders is low, suggesting that raw spotlight counts may greatly underestimate densities.
  • The three surveyed coupes (Barjarg Flat, Mr Hat and Tartan) have a Greater Glider population of ca. 500 Greater Gliders.
  • Greater Gliders in the Strathbogie Forest occur at densities of 2 to 4/ha. [Extrapolating, nine remaining coupes (370 ha) on the TRP have a Greater Glider population of 740 to 1480 individuals.]
  • Generally, hollow-bearing trees were larger in coupes (mean DBH 118 cm), than outside coupes (mean DBH 89 cm), [suggesting that logging coupes are targeting higher conservation value areas of forest].
  • Higher numbers of Greater Gliders were found on transects with large trees, particularly trees >100 cm DBH.
  • The results of the study indicate that higher quality habitat for Greater Gliders includes areas containing a high proportion of Blue Gum and Mountain Gum and with a high proportion of trees larger than 100 cm DBH.

Hey Dan Andrews – hands off Mr Hat!

And the other eight coupes due to be logged in the Strathbogie Forest – 369 ha in total.

Strathbogie Forest TRP coupes detail

The two coupes recently logged (underlined) and remaining nine coupes on the chopping block.

You’ve already logged some of the highest conservation value forest left in the entire Strathbogie Ranges and it looks like Mr Hat and Tartan coupes are next, yet both have been shown by government surveys to have high numbers of Greater Gliders. Scientific research has repeatedly demonstrated that healthy, intact, carbon-dense forests are one of the best and most cost-effective defenses available to avert dangerous climate change, yet native forest logging continues, here in the Strathbogie Forest and across Victoria.

Government policy on logging native forests is completely out of step with regional Victorian’s opinion and values. And that’s certainly true in the Strathbogies!

 

Mr Hat coupe is on the east side of Stan’s Tk in the Parlour’s Creek catchment, to the north-east of Parlour’s Creek coupe (logged in 2017). And it’s adjacent to Stan’s coupe, (logged in 2009). Government surveys found the equivalent of 20, 12 and 10 Greater Gliders per kilometer (equiv.) in the three survey transects – detection rates that protect  forest from logging elsewhere in Victoria!

Protecting the Strathbogie Forest

A vision for the future

The Strathbogie Forest has been ignored for too long. The Victorian Government has the opportunity to capitalize on the strong community support and compelling weight of policy, which underpin the significant benefits of protecting the Strathbogie Forest.

Though modest in size, the statewide significance of this forest is now beyond argument. Its protection in a conservation reserve is urgently required for meeting National Reserve System targets, Victorian Government protection commitments and for the survival of iconic national and state endangered fauna species.

Report coverForest protection will provide, not only significant biodiversity outcomes, but demonstrable support for regional communities, a genuine commitment to people caring about nature, improved visitor experience, and increased tourism opportunity. Regional communities and businesses want protection of the natural environment and the benefits of sustainable economic development, particularly the burgeoning economies around nature-based tourism – these will return real benefits to regional Victoria.

Local communities and many thousands of Regional Victorians are calling on the Victorian Government to protect the Strathbogie Forest as a conservation reserve.

… and cut for firewood.

Barjarg Flat coupe contained some of the highest quality forest left in the entire Strathbogie Ranges and was home to the highest ever documented Greater Glider numbers in Victoria. So, how does the Victorian government manage habitat of this EPBC Act and FFG-listed species? Easy – they let Vicforests loose. Continue reading
