Retain wildlife corridors in logged areas
A replicated study (year not stated) of forest at 49 sites in Victoria, Australia (Lindenmayer et al. 1993) found that linear corridors of unharvested trees retained after tree harvesting operations supported seven species of arboreal marsupial. From 402 tree hollows surveyed, 69 arboreal marsupials were recorded, at 54 trees. Greater glider Petauroides volans and mountain brushtail possum Trichosurus caninus were the most frequently recorded species, accounting for 78% of observations. Sites were chosen where forest had regrown for around 50 years, following wildfires in 1939, and then been felled years <4 years before mammal observations, but leaving a linear strip. Strips were 125–762 m long and had average widths of 30–264 m. Forty-three strips comprised Eucalyptus regnans stands and six were of Eucalyptus delegatensis. Strips had 1–29 trees with hollows. Marsupial occupation of tree hollows was determined by direct observations.
