The Gunnedah Koala Conservation Plan, released last year, said the loss of habitat remains the most serious threat facing koalas today.
The plan said historically, the loss and fragmentation of habitat was a significant factor in the decline of koalas.
“During the 1986-87 survey of the distribution of koalas in NSW, most koala records were from private or leasehold lands where they are particularly vulnerable to habitat loss and fragmentation.
“The 2006 community-based survey confirmed that the centres of populations identified in the 1986-87 survey remain the same, and that the bulk of the koala population resides on private or leasehold lands.
“As a result of clearing, much of the remaining habitat now occurs in isolated fragments.”
