Abstract: | Suburban forest fragments often experience heavy recreational and waste disposal use, with considerable damage to the vegetation.
To suggest strategies for conservation of the forest flora, spatial distributions of human impact were described in 40 fragmentary
stands in northern New Castle County, Delaware. The distribution of human impact showed a significant bias to the forest edge,
with 95% of localized damage occurring in the first 82 m. Forms of impact related to lawn maintenance fell significantly closer
to the edge than impacts related to recreation and showed the strongest edge orientation. Edge distances of campsites, vandalized
trees, and firewood gathering were negatively correlated with distance to the nearest graded road, indicating the importance
of road access. Several forms of impact were also clustered near footpaths, although distance to paths was independent of
edge distance in all cases. In terms of penetration of the forest and severity of damage, human impact greatly exceeds natural
edge effects reported for this community. These findings suggest that damage may be minimized by limiting road access and
avoiding the creation of small forest fragments. |
