Xerces has programs encouraging golf courses to plant pollinator habitat in their margins, etc.  That may not be the best approach.  To keep everything green, dense turf, a carpet-like outdoor habitat, many courses make heavy use of chemicals, including fertilizers, pesticides - both herbicides and insecticides.  Some are built on old industrial sites - the pig's ear to a silk purse approach.  That can have a real downside if the industrial contaminants haven't been removed.   Not only can this pose a health hazard, but sometimes one get amazing side-effects.  One course built over a waste site, more or less capping the crude with a clay layer.  On hot days, after watering or a rain storm, the turf would separate and bubble up due to the gases from the waste.
