I'm fairly new at GIS and am using ArcMap to calculate the population density of lizards on an island. On our island, we have about 80 trees, and each tree is mapped as a polygon on a single layer. We have a database of several thousand lizards that we have captured on these trees (and noted capture location). Our goal is to add the lizards to the map to calculate density across the island. Right now, we have attributes for each tree that are #males, #females, #total, which we hoped would give use the ability to calculate both density and sex ratio.
Can we use these attributes to calculate density of specific areas with a given kernel size? Based on what I've read, it seems like you might only be able to calculate density of lines and points.
