It would seem to me a limited number of species is better than none.  I have always suspect (on rare occasions this hypothesis been somewhat confirmed) that when or if you can convince farmers to allow a few weeds and flowers along the margins of fields that honeybees do better over the long run.  If you do the math and calculate the land mass devoted to these margins it is not a inconsequential number.  Certainly the relationship between possible forage areas to hives works out better for folks who operate smaller number of hives per yard (which as far as I know tends not to be the case of many commercial bee keepers).
