Install rope bridges between canopies
A replicated study in 2008–2011 of five rope bridges at four sites along a highway through woodlands in New South Wales, Australia (Goldingay et al. 2013) found that rope bridges were used by six mammal species. Bridges were used by squirrel gliders Petaurus norfolcensis (44 records at two bridges), feathertail gliders Acrobates pygmaeus (nine records at three bridges), common ringtail possums Pseudocheirus peregrinus (seven records at one bridge), common brushtail possums Trichosurus vulpecula (33 records at two bridges), sugar gliders Petaurus breviceps (15 records at two bridges) and black rats Rattus rattus (19 records at two bridges). Two rope bridges across the highway (42–75 m long) were monitored at one site. Single bridges (each approximately 50 m long), crossing creeks underneath the highway at each of two sites, were monitored. At the fourth site, a rope bridge was suspended from a series of poles along a 70-m-long land bridge over the highway. Sites were up to 270 km apart. Bridges, erected in 2004–2008, comprised rope mesh either laid flat or formed into tunnels. They were monitored by 1–3 camera traps/bridge for 42–503 nights/camera.
