The researchers propose instead to move animals between forest fragments to increase genetic diversity within the central groups.
Secondary forests may also buffer edge effects around mature forest fragments and increase connectivity between them.
So this study suggests that by providing other bee species, forest fragments near crop areas can help keep the pollination going.
The maples take enthusiastically to both the forest fragments and the deforested patches between.
