Healing the planet: Conservation of the world`s tropical forests
Hubbell, Stephen P. .
Understanding tree species' rarity in tropical forests and its implications for conservation .
Tropical lowland wet forests contain an extraordinary diversity of tree species, but most of these species are rare to exceedingly rare, occurring at adult densities of only a few adult trees per square kilometer. The global network of large, permanent tropical forest plots contains over 4.5 million trees of approximately 8,500 tree species, representing about 10% of the known tree species in the tropics. However, half of these tree species collectively make up less than 1% of the individuals. What is poorly known is the extent to which locally rare species are also globally rare. This paper considers the implications of rarity for the conservation of tropical forest tree diversity.
