Abstract

Although botanists have been actively collecting in Utah for well over a century, the distribution of many plants are as yet imperfectly known. This is, in part, due to the scattered nature of Utah herbarium material. Also the terrain of the state has impeded collection in more rugged and remote areas. The present study gathers together the data from the major collections of native Utah trees and clarifies our present understanding of tree distributions in the state. The older collection records have been extensively supplemented by the field work of the author and other botanists.

The great diversity of environments due to geography, physiography, and climatic features of Utah has resulted in an interesting tree flora of fifty species and at least three naturally occurring, recognized hybrids. Although a majority of Utah's trees are mountain species, a number are strictly desert plants restricted to the Virgin or Colorado River drainages.
