Regional gradient analysis and spatial pattern of woody plant communities in Oregon forests
Ohmann JL and Spies TA. 1998. Regional gradient analysis and spatial pattern of woody plant communities in Oregon forests. Ecological Monographs. 68(2):151-182
Knowledge of regional-scale patterns of ecological community structure, and of factors that control them, is largely conceptual. Regional- and local-scale factors associated with regional variation in community composition have not been quantified. We analyzed data on woody plant species abundance from 2443 field plots across natural and seminatural forests and woodlands of Oregon to identify and quantify environmental, biotic, and disturbance factors associated with regional gradients of woody species composition; to examine how these factors change with scale (geographic extent) and location; and to characterize and map geographic patterns of species and environmental gradients.
