The Historical Complexity of Tree Height Growth Dynamic Associated with Climate Change in Western North America

The effect of climate on tree growth has received increased interest in the context change. However, most studies have been limited geographically and with respect to species. Here, sixteen species western North America were used investigate response trees Forest inventory data from 36,944 stands established between 1600 1968 throughout summarized. height (top at a breast-height age 50 years) healthy dominant co-dominant was related annual summer temperatures, Palmer Drought Severity Indexes (PDSIs), establishment date (ED). Climate-induced patterns then tested determine links spatial environment (geographic locations soil properties), species’ range (coastal, interior, or both), traits (shade tolerance leaf form). Analysis performed using linear mixed model (total species) general (species scale). Climate change globally beneficial, except for Alaska yellow-cedar (Chamaecyparis nootkatensis (D. Don) Spach), magnified coastal-ranged, high-shade-tolerant, broadleaf species, mostly northernmost extents these ranges. Nevertheless, more complex properties. A decline some observed higher latitudes elevations possibly cloudiness, precipitation, drought (in interior areas). These results highlight spatio-temporal complexity recent global
