Abbas Naqibzadeh

Dear Dulan Jayasekara;

For small-scale modeling, you need to categorize environmental variables based on the species under study, using local data appropriate to the scale and species, i.e. less class distance, local climate, and so on.

Dulan Jayasekara

Dear Abbas Naqibzadeh , I do agree.

Thanks Yurii Moskalenko it will be quite useful.
