Hello everyone,

I'd like to ask about the best sampling design or method to record species occurrences (I'll used the occurrences data for species delimitation analysis)

The species I want to study has only 7 occurrences so far (from herbaria specimens record) but I think there are more since I found several populations outside the specimens' localities.

In several researches that I read, some put study area in grid and then surveyed the area in which the species was likely to be found. Is it robust enough?

Thank you in advance
