Asexual reproduction has been observed to be more frequently associated with marginal habitats orwith higher levels of disturbance. Here we examined frequencies of clonal reproduction across populations ofFagus grandifolia witll varying levels of disturbance and habitat quality. We used ISSRs to identify clonalgenotypes at each of five sites. Three of the sites were typical temperate habitats with relatively lowdensities of stems and were below 1,100 m, and two sites were above 1,370 m, possessed a high density ofstems, and were characteristic of sub-alpine beech gap populations. The frequency of clonal reproductionvaried substantially across sites and appears to be greater where disturbance is more severe.
