GIS certificate programs. Worth it?

I’m looking at ecology/biology MS graduate programs for the fall of 2020. Lately I’ve been thinking that I would love to pursue ecology with some sort of GIS component. I have a pretty good background in GIS already as well as research biology and would love to combine them for a career in conservation.

I was wondering if I should look into GIS certificate programs alongside my focus in ecology/biology graduate programs or if it would be more beneficial to find faculty that directly integrate GIS into their ecological research. Would either of these tactics be helpful, or would me already having an undergraduate minor in GIS be enough? Thank you!!
