Summary

We developed habitat suitability models for occurrence of three invasive riparian woody plant taxa of concern to Department of Interior land management agencies, as well as for three dominant native riparian woody taxa. Study taxa were non-native tamarisk (saltcedar; Tamarix ramosissima, Tamarix chinensis), Russian olive (Elaeagnus angustifolia) and Siberian elm (Ulmus pumila) and native plains/Fremont cottonwood (Populus deltoides ssp. monilifera and ssp. wislizenii, Populus fremontii), narrowleaf cottonwood (Populus angustifolia), and black cottonwood (Populus balsamifera ssp. trichocarpa and ssp. balsamifera). We generally followed the modeling workflow developed in Young et al. 2020. We developed models using five algorithms with [...]

Purpose

(1) to provide information and documentation on the potential distribution of tamarisk, Russian olive, and Siberian elm in the conterminous western USA, (2) to compare the potential distributions of these invasive riparian trees to potential distributions of dominant native riparian cottonwoods, and (3) to evaluate risks of future or undetected invasion by tamarisk, Russian olive, and Siberian elm in major watersheds of the western USA.
