Note: Biome and ecoregional
statistics were gathered using the WWF
Terrestrial Ecoregions GIS Database (Olson, D. M.
and E. Dinerstein. The Global 200: Priority Ecoregions
for Global Conservation. Annals of the Missouri Botanical
Garden 89:125-126.). For the purposes of current assessment
we combine several biomes together: dense tropical and
subtropical forests (group of the tropical and subtropical
moist broadleaf forests, tropical and subtropical dry
broadleaf forests and tropical and subtropical coniferous
forests biomes); temperate broadleaf and mixed forests
(group of the temperate broadleaf and mixed forests
and temperate grasslands, savannas and shrublands biomes),
boreal forests (group of the boreal forests/taiga and
tundra biomes), tropical and subtropical woodlands and
savannas (group of the tropical and subtropical grasslands,
savannas and shrublands, flooded grasslands and savannas
and Mediterranean forests, woodlands and scrub biomes).
The temperate coniferous forests and montane grasslands
and shrublands biomes are used as in WWF database.
