Bear Island is not all that farmable being composed of topsoil on bedrock. The effects of the famine are here as well. The bugbear population has been held in check and is not expanding. Wildlife is present but in lower sustainable numbers given the barreness of the vegetation and prey.As to farming - anything large scale is out. Small scale plots would need to be defended against the bugbears and natural predators such as deer, rabbits and the like. Plant and go will not work.Also usable water is a concern. It may be surrounded by seawater, but you can't water crops with seawater. The island does have several natural springs and small streams, brooks and a few small marshes and lakes but no major fresh water ways to be easily used with out significant infrastructure. Drilling wells in bedrock is something a dwarf might tackle but not most others.
