Summary

This dataset presents observations and measurements of riparian plant invasion, community composition, and environmental conditions at 238 bridge crossings in four western USA river basins: the Colorado Headwaters, upper/middle Rio Grande, upper Arkansas River, and South Platte River (281,946 square kilometers). The 238 sites are a stratified random sample of all bridge crossings in the river basins, with roughly equal numbers of sites in landscapes dominated by (1) urban and residential (developed) land-use, (2) agricultural (cultivated) land-use, and (3) undeveloped land cover. The dataset includes field observations of stem counts for three non-native riparian woody plant taxa (Tamarix ramosissima x T. chinensis hybrids - tamarisk [...]

Purpose

These data were collected to increase knowledge of the frequency, abundance, rank dominance, size class distributions, and spatial distributions of Tamarix ramosissima x T. chinensis hybrids, Elaeagnus angustifolia, and Ulmus pumila in riparian ecosystems in the western USA. In addition, the dataset was created to identify environmental conditions associated with invasion by these three non-native taxa, with a particular focus on land-use conditions.
