Spotlighting is a widely used method to survey a range of nocturnal mammals, birds, reptiles and frogs. In Australia, spotlighting can be particularly useful for determining presence and density of otherwise elusive arboreal marsupials such as gliders, koalas and possums, nocturnal birds including owls, and nocturnal reptiles and frogs.
As with remote camera surveys, spotlighting has a relatively low invasive impact on target, and other, species and can be extremely useful for surveying species where remote camera survey detection is unlikely – such as nocturnal arboreal species which use the high canopy like greater gliders.
Spotlighting transects are often used to provide an accurate assessment of population changes in mammal populations for conservation and management purposes.
Spotlighting transects or strips are commonly run in conjunction with call playback. Call playback is a technique useful for detecting the presence of a variety of species, including owls, mammals and frogs.
Treetec is in a position to be able to provide both the ecological expertise, and equipment necessary, for both spotlighting and call playback for a variety of species. We are also able to run these surveys in combination with thermal imaging survey, if required.
