Booming deer populations on some Gulf Islands are driving away songbirds and leaving the area susceptible to invasion by foreign species, says a recent study.
Following hunting bans on many small islands in the 1970s, deer populations grew. People began feeding deer, which compounded the problem. Now residents of at least one island are looking at sterilization as a control measure, but are getting little support from the provincial government.
I'll post my own synopsis of this study--it is quite good.

I've included a picture from the study that shows vegetation on low, medium, and high deer density islands.
