説明

<jats:p>Leaf area of nature coniferous forest communities of western Oregon appears to be related primarily to site H<jats:sub>2</jats:sub>O balance rather than characteristics of tree species composing the community. Leaf areas were determined for stands in communities ranked along measured gradients of precipitation and evaporative potential. Nine coniferous and 1 deciduous tree species were found in the various stands along these gradients. Leaf areas of these stands were linearly correlated with a simple site H<jats:sub>2</jats:sub>O balance index computed from measurements of growing season precipitation, open pan evaporation, and estimates of soil H<jats:sub>2</jats:sub>O storage. Species composition had no apparent influence on the relation between community leaf area and site H<jats:sub>2</jats:sub>O balance.</jats:p>
