Abstract:
Contrary to the general trend in the tropics, forests have recovered in Puerto
Rico from less than 10% of the landscape in the late 1940s to more than 40%
in the present. The recent Puerto Rican history of forest recovery provides
the opportunity to study the ecological consequences of economic globalization,
reflected in a shift from agriculture to manufacturing and in human migration
from rural to urban areas. Forest structure rapdly recovers through secondary
succession, reaching mature forest levels of local biodiversity and biomass
in approximately 40 years. Despite the rapid structural recovery, the legacy
of pre-abandonment land use, including widespread abundance of exotic species
and broadscale floristic homogenization, is likely to persist for centuries.
