|Abstract: ||We assessed tree species density and diversity in 12 1-ha plots in four forests of the Albertine rift, western Uganda. There were 5747 trees of diameter ≥ 10 cm in 53 families, 159 genera, and 212 species. Density ranged between 344 and 557 trees ha−1 (average 479 trees ha−1). Tree species diversity was highest in the Bwindi and Budongo forests. The Euphorbiaceae family was the most species rich (25 species) followed by Rubiaceae and Meliaceae with 16 species each. Canonical Correspondence Analysis (CCA) showed that major gradients in environmental variables influenced tree species distribution. Sample scores on ordination axes 1 and 2 were strongly correlated with pH and altitude, respectively. Correlated with rainfall and other soil factors, pH and altitude are presumed to be among the most important in influencing the distribution of tree species in the Albertine rift forests. Strategies that take account of variations in pH and elevation are required to conserve tree species in forests of the Albertine rift.|
