Abstract: | Land-use allocation has important implications for the conservation and management of tropical forests. Peru’s forestry regime
has recently been reformed and more than 7 million ha has been assigned as forest concessions. This potentially has a drastic
impact on the land-use practices and species composition of the assigned areas. Nevertheless, the environmental variation
found within the concessions and the process applied to delimit them are poorly studied and documented. Thus, it is difficult
to estimate the biological impacts of forestry activities in concessions or plan them sustainably. This paper reveals the
characteristics of the current concession allocation in Loreto, Peruvian Amazonia, using environmental and access-related
variables and compares the concessions to other major land-use assignments. The work draws on a number of data sets describing
land-use, ecosystem diversity, and fluvial network in the region. According to our data, certain environment types such as
relatively fertile Pebas soils are overrepresented in the concessions, while others, like floodplain forests, are underrepresented
in comparison to other land-use assignments. Concessions also have less anthropogenic disturbance than other areas. Furthermore,
concessions are located on average further from the river network than the other land-use assignments studied. We claim that
forest classification based on productivity, soil fertility, accessibility, and biodiversity patterns is an achievable long-term
goal for forest authorities in Peru, and in many other tropical countries. We present a rough design of a geographic information
system incorporating environmental, logging, and access-related data that could be applied to approach this goal in Peru. |
