We explored the effect of tree species richness on tree volume productivity at the global scale using repeated forest inventories from 777,126 permanent sample plots in 44 countries containingmore than 30 million trees from 8737 species spanningmost of the global terrestrial biomes.
Balancing forest conservation with resource extraction by local people is challenging. In the mountain forests of Bwindi Impenetrable National Park in Uganda, this was addressed by permitting regulated access to certain forest products in specific areas by authorized local people.
Monitoring of environmental parameters is one of the highest priorities in the evaluation of environmental status of water resources and in environmental protection policy.
Vultures provide critical ecosystem services, yet populations of many species have collapsed worldwide.
Four species of African vultures have been recategorized as Critically Endangered, and two as Endangered, on the IUCN Red List. Their declining status is attributed partly to the impacts of widespread poisoning.
Six out of seven vulture species whose global ranges lie largely or wholly within Africa are listed as globally threatened.
Most Parus species live in the tropics or subtropics, and are likely to show life history traits associated with relatively high survival and low fecundity. Based on a 15-year study, we provide the first detailed account of the life history traits of an equatorial Parid, the Stripe-breasted Tit P.
Uganda is losing biodiversity at an alarming rate. Habitat change and direct exploitation by humans are among the most important reasons for this crisis. Forest wildlife is particularly affected with a need for harmonious living through collaborative forest management.
Trade and use of Non-timber forest products (NTFPs) has often been suggested as a means through which forest dependent people can improve their livelihoods to overcome poverty. Many projects have indeed promoted trade and use of NTFPs as a means of achieving development and conservation goals.
Local communities who live close to protected tropical forests often depend on them for woodfuel, their main source of energy. The impacts of fuelwood extraction in humid forests are rarely studied, yet the extraction of wood for fuel can impact forest structure, function and biodiversity.
