Snowy Mountains residents are now being given the opportunity to glimpse what local wildlife gets up to when there's no one around.
To mark the beginning of Science Week, the Office of Environment and Heritage released the preliminary results of a major state-wide project.
The project, known as WildCount, is a long-term, fauna monitoring project which uses remotely located motion-sensitive cameras to record fauna within almost 150 parks and reserves across the Great Eastern Ranges.
The early results include almost 400,000 digital images of animals in the wild, available for viewing on Flickr.
OEH Chief Executive, Sally Barnes, says it's crucial the observation work continues over a long period.
"It's too early to tell just what changes might be occuring among the various species being recorded, but it's important work that needs to be continued," she said.
"With time, the data collected to identify trends in species patterns can be linked to patterns in other variables such as land use, and climate change that will ultimately help us in our management of the NSW environment."
Among the many images, there are some interesting scenes including three images of a Lyrebird attacking a snake, interactions between wallabies and their young, and a new record for the endangered Brush-tailed Rock-wallaby.
