Environment and History in a Rich Mesic Forest in Western Massachusetts 1999-2001

In rich mesic forests, modern vegetation varies among primary versus post-agricultural, secondary forests, in part as a result of differential rate and ability of forest herbs to colonize after disturbance. Species with seeds lacking morphological adaptations for dispersal (barochores) and those which produce seeds with elaisomes to encourage ant dispersal (myrmecochores) may remain less frequent in secondary forests for decades or more.
