Therefore, the ecology of this large forest biome is y o u n g e r than any other (Takhtajan, 1986). The distribution of species, and the species composition of stands are strongly influenced by t o p o g r a p h y and soils. I m p o r t a n t genera include Abies, Betula, Larix, Picea, Populus, and Salix. Picea and Larix commonly occur on poorly drained lowland soils. Pines c o m m o n l y occupy well-drained u p l a n d soils, whereas Populus, Abies, Salix, and certain species of Picea occur on the finer-textured upland soils.

However, an area notable for such forests is the n o r t h w e s t coast of the United States, represented by Seattle (Fig. 1c), which has cooler s u m m e r s than the temperate d e c i d u o u s zone, w a r m e r w i n t e r s m t h e average m i n i m u m t e m p e r a t u r e for any m o n t h is never below z e r o - - a n d a different precipitation pattern. Highest precipitation is in the winter months, with very little d u r i n g the p e r i o d of highest evaporation, so significant water deficits a n d r e d u c e d tree growth d u r i n g s u m m e r are the n o r m .

Kikuzawa (1991), using a cost-benefit analysis, demonstrated that "evergreeness" should have a bimodal distribution with peaks at low latitudes (tropics) and high latitudes (boreal). His general biogeographical distribution pattern agrees well with observed vegetation patterns, except in two regions. First, although temperate forests occur predominantly from 30 ~ to 55 ~ latitude, broad-leaved evergreen species dominate forested landscapes in the southern hemisphere, whereas broad-leaved deciduous tree species predominate in the n o r t h e r n hemisphere.
