Endangered and threatened plants of Utah are evaluated as to their distribution in phytogeographic subdivisions, substrates, plant communities, elevations, and geological strata. The phytogeographic subunits were partitioned and comparisons made of distribution as outlined for the parameters cited above. A predictive model is suggested based on the nonrandom distribution of endemic plant species.
