[R-sig-Geo] diversity zones

> I am trying to create a diversiy zones based on tree species distribution,  from neighboor analysis. I identify the 20th neighboor from each one of my tree species, and counted the richness associated to each one. I also have the associated distance to each kth tree... So, my study area is 100x100 m..As I want zone areas, how can I divide this area, so it can represent the richnees found? From 265 species, I am interested to do this for 30 one, generating maps for each one.
