M. Peinado et al., PHYTOSOCIOLOGICAL, BIOCLIMATIC AND BIOGEOGRAPHICAL CLASSIFICATION OF WOODY CLIMAX COMMUNITIES OF WESTERN NORTH-AMERICA, Journal of vegetation science, 8(4), 1997, pp. 505-528
In this study, combining the Braun-Blanquet phytosociological approach
with numerical methods (cluster analysis and principal coordinate ord
ination), woody climax associations of western North America are descr
ibed, ranging from NW Baja California (Mexico) to Alaska (USA), and in
cluding some interior zones of Idaho and Montana (USA), Alberta, Briti
sh Columbia and the Yukon Territory (Canada). 95 floristic association
s are identified, and each is characterized by floristic combination,
biogeographical range, and bioclimatic conditions.
