摘要: Creating, restoring, and sustaining forests in urban areas are complicated by habitat fragmentation, invasive species, degraded soils. Although there is some research on the outcomes of reforestation plantings during first 5 years, little longer term outcomes. Here, we compare successional trajectories restored unrestored forest sites 20 years after initiating restoration. The located within Rodman's Neck area Pelham Bay Park, northeast corner Bronx New York City (NYC), U.S.A. Compared with sites, saw improvements species diversity, greater structure complexity, evidence regeneration retention native tree sites. In addition, found differences restoration depending level intervention: clearing exotic shrubs vines planting trees improved diversity canopy closure to a extent than exotics alone, mechanical removal plants further measures restoration, such as regeneration. results this study suggest that goal sustainable ecosystem dominated other plant may not be achievable without continued human intervention site. these indicate approach adopted NYC's practitioners moving site toward more desirable vegetative community species.
