I have been wondering about this for some time. Often i will come across water dragons in places where there is no water (e.g. Alexander headland) and other times i come across a nice body of water, but never see any water dragons. (think about all the small lakes on campus).
I want to use GIS style mapping in R or other wise to overlay the distribution of water dragons with surface features. The comparison i want to make, is a water dragons preferring habitats on the edge of water bodies, or are water dragons just preferring areas of a steep slope (which just happen to be associated with water bodies, or both?
