The editor’s alternative is the article by Christianson et al.:   “Estimating true density in giant, alpine herbivores utilizing Google Earth imagery”

Dependable estimates of inhabitants dimension and density are important for each analysis and administration, but very troublesome to attain. That is notably true for wide-ranging species in distant, hard-to-access areas. On this paper, Christianson et al. describe a easy and cost-effective method to estimate abundance of enormous, conspicuous mammals in open habitats utilizing   freely   accessible   Google   Earth  satellite tv for pc imagery. They used an unbiased double-observer protocol to estimate elk  Cervus elaphus  density in Yellowstone Nationwide Park, USA.

Whereas Yellowstone elk have been the topic of quite a few research, density estimates have been restricted to their extra accessible,  lower-elevation winter vary; the distant and huge  Alpine summer time vary nonetheless that had by no means been systematically surveyed. Related survey protocols might be helpful additionally for different giant species, particularly when excessive detectability within the open permits for prime precision of density estimates, as was the case for Yellowstone elk.
