The coastal forest of Gabon abounds in monospecific secondary Aucoumea klaineana stands derived from natural regeneration after shifting cultivation. This paper aims to describe the changes in the structure and dynamics of these stands with age. It then assesses the impact of selective thinning i...

Costs of applying silvicultural treatments prescribed to increase yields of timber and non-timber forest products from natural forests should be calculated differently for industrial logging companies, private non-industrial forest owners, and community based forest management operations. For for...

To mimic catastropic disturbances which have favored the establishment of natural stands rich in mahogany (Swietenia macrophylla), two 5000 square meter clearings were established in each locations using each of three treatments: complete felling; slash and burn; machine-clearing with uprooted al...

Short-term growth responses in individuals of four commercial tree species (Laetia procera, Simarouba amara, Tapirira guianensis, and Vochysia ferruginea) were evaluated one and two years after `liberation thinning' in a young (4.5-year-old), dense secondary forest stand located in an agricultura...

Four years of annual diameter measurements of 75 big-leaf mahogany (Swietenia macrophylla King) trees in natural forests in northwestern Belize were analyzed to determine growth rates. Mean diameter increment among the sample trees exceeded 1 cm y-1, with slightly higher growth rates among trees ...

The most important timber species in Neotropics, mahogany (Swietenia macrophylla) is still harvested from natural forests. The difficulty of ensuring its regeneration in logged-over forests was a primary reason for listing this species in CITES appendix II in 2003, requiring producer countries to...

The annual diameter measurements four years of 75 big-leaf mahogany (Swietenia macrophylla King) trees in natural forests in northwestern Belize were analyzed to determine growth rates. Mean diameter increment exceeded 1 cm year-1, with slightly higher growth rates in trees > 50 cm dbh. Inter-ind...

Inclusion of improved forest management as a way to enhance carbon sinks in the Copenhagen Accord of the United Nations Framework Convention on Climate Change (December 2009) suggests that forest restoration will play a role in global climate change mitigation under the post-Kyoto agreement. Alth...

Reduced-impact logging (RIL) and conventional techniques (CNV) were compared in a mixed dipterocarp hill forest in East Kalimantan in three blocks of about 100 ha each. Damage was evaluated using pre- and post-harvesting assessments in 24 one-hectare sample plots. RIL techniques nearly halved the...
