These georeferenced data were collected and complied as part of a project to map riparian vegetation, tamarisk occurrence and Russian olive occurrence in the Colorado River Basin.The tamarisk & Russian olive data is mainly collected in Colorado, Utah and Arizona. Sampling is done opportunistically as land ownership, access, and logistics allow.Users of these maps and other analysis products are solely responsible for interpretations made from these products. The Natural Resource Ecology Laboratory makes every effort to ensure this map is free of errors but does not warrant the map or its features are either spatially or temporally accurate or fit for a particular use. The Natural Resource Ecology Laboratory provides this map without any warranty, either express or implied.Natural Resource Ecology Laboratory (NREL)These shapefiles contain 353 species occurrence and absence records for Russian olive (Elaeagnus angustifolia) and tamarisk (Tamarix spp.) along rivers within the Colorado River Basin in Arizona, Colorado, Nevada, and Utah.ZIPXMLShapefileengfield datariparian vegetationInvasive speciesDatasetThe material is open access and distributed under the terms and conditions of the Creative Commons Attribution Share-Alike International License (http://creativecommons.org/licenses/by-sa/4.0/).
