Is it possible to estimate population density from line transect encounter data with no distance metric, simply frequency of encounter data?
I have several years of encounter data for spoor on a network of transects in an isolated National Park. The data do not include a distance metric (therefore the programme Distance doesn't work), but are simply record the frequency and location of encounters along a network of transects. The study species has a home range of approximately 1km2, is it possible to estimate population density from these data? Thank you!
