Libraries, 2017) Hatcher, Emma; Young, Nicholas; Evangelista, Paul; Vorster, Tony; West, AmandaAn ArcGIS created Mapbook atlas of the results of modeling riparian vegetation across the Colorado River Basin. The atlas includes an overview of the Colorado River Basin with these model results as well as an indexed tile-by-tile map of the results for a more detailed view. Detailed methods can be found in Woodward et al. (In prep).Item Open Access 2016 riparian vegetation within the Colorado River Basin(Colorado State University. Libraries, 2017) Evangelista, Paul; Woodward, Brian; West, Amanda; Vorster, Tony; Young, Nicholas; Girma, Rebecca; Hatcher, Emma; Carroll, Sarah; Vashisht, Amandeep; Tilakamonkul, Chanin; Campbell, EmilyGeoTiff raster of 2016 riparian vegetation within the Colorado River Basin. This map was created from a random forest model developed in Google Earth Engine.Item Open Access Mapbook atlas of tamarisk occurrence for 2016 for select Landsat scenes(Colorado State University. Libraries, 2017) Evangelista, Paul; Young, Nicholas; Vorster, Tony; West, Amanda; Woodward, Brian; Mayer, Timothy; Hatcher, Emma; Girma, Rebecca; Carroll, Sarah; Vashisht, Amandeep; Tilakamonkul, Chanin; Campbell, Emily; Vahsen, Megan; Carver, Daniel; Sullivan, Julia; Martinez, AudreyAn ArcGIS created Mapbook atlas of the results of modeling tamarisk occurrence in select scenes in Colorado River Basin for 2016. The atlas includes an overview of the Colorado River Basin with these model results as well as an indexed tile-by-tile map of the results for a more detailed view.Item Open Access Elevation (10 meter) for Colorado River Basin(Colorado State University. Libraries, 2017) Evangelista, Paul; West, Amanda; Young, Nicholas; Vorster, Tony; Girma, RebeccaThis elevation layer, which is part of the National Elevation Dataset (NED), is available from the USGS National Geospatial Program. It has a 10 meter resolution and covers the Colorado River Basin.Item Open Access Map of tamarisk occurrence in Landsat scenes across Colorado River Basin from 2005 to 2007(Colorado State University. Libraries, 2017) Evangelista, Paul; Girma, Rebecca; Young, NicholasAn overview map of tamarisk location data between 2005-2007 that fell within WRS2 Landsat scene extents that overlap with the Colorado River Basin.Item Open Access Valley bottom extraction tool results for Colorado River Basin(Colorado State University. Libraries, 2017) Evangelista, Paul; Woodward, Brian; West, Amanda; Vorster, Tony; Young, Nicholas; Girma, Rebecca; Carroll, Sarah; Vashisht, Amandeep; Tilakamonkul, Chanin; Campbell, Emily; Hatcher, EmmaValley Bottom Extraction Tool (V-BET) was used to spatially define riparian corridors based on topography and vegetation. The V-BET algorithm was applied to all streams and rivers present within the Colorado River Basin (CRB) that were less than or equal to Strahler stream order "3" (USGS National Hydrologic Database, 2016), thereby capturing the extent of valley bottoms and riparian corridors along the majority of large streams and rivers within the expansive CRB network.Item Open Access 2006 riparian vegetation within the Colorado River Basin(Colorado State University. Libraries, 2017) Evangelista, Paul; Woodward, Brian; West, Amanda; Vorster, Tony; Young, Nicholas; Girma, Rebecca; Hatcher, Emma; Carroll, Sarah; Vashisht, Amandeep; Tilakamonkul, Chanin; Campbell, EmilyGeoTiff 30 meter raster of 2006 riparian vegetation within the Colorado River Basin. This map was created from a random forest model developed in Google Earth Engine.Item Open Access Tablet field data collection (shapefiles)(Colorado State University. Libraries, 2017) Vorster, Tony; Evangelista, Paul; West, Amanda; Young, Nicholas; Sturtevant, Robert; Mayer, Timothy; Woodward, BrianThese shapefiles contain the 3,493 species occurrence and absence records for Russian olive and tamarisk represented in the Tablet Data Collection csv file. These are organized by location.Item Open Access Cover field data collection(Colorado State University. Libraries, 2017) Evangelista, Paul; Young, Nicholas; Vorster, Tony; West, Amanda; Woodward, Brian; Mayer, Timothy; Girma, Rebecca; Carroll, Sarah; Vashisht, Amandeep; Tilakamonkul, Chanin; Campbell, Emily; Hatcher, Emma; Vahsen, Megan; Carver, Daniel; Sullivan, Julia; Martinez, AudreyThese 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.Item Open Access Tablet field data collection (csv)(Colorado State University. Libraries, 2017) Vorster, Tony; Evangelista, Paul; West, Amanda; Young, Nicholas; Sturtevant, Robert; Mayer, Timothy; Woodward, BrianThis dataset contains 3,491 species occurrence and absence records for Russian olive (Elaeagnus angustifolia) and tamarisk (Tamarix spp.) along rivers within the Colorado River Basin in Arizona, California, Colorado, Nevada, New Mexico, and Utah.Item Open Access Mapping native and non-native riparian vegetation in the Colorado River Watershed(Colorado State University. Libraries, 2018-10-24) Evangelista, Paul, author; Young, Nicholas, author; Vorster, Tony, author; West, Amanda, author; Hatcher, Emma, author; Woodward, Brian, author; Anderson, Ryan, author; Girma, Rebecca, authorUsing remote sensing to map riparian vegetation, particularly single species such as tamarisk and Russian olive, requires georeferenced occurrence locations with estimations of foliar cover to train remote sensing-based models. This report details on the data, resources, methods and results to developing riparian vegetation, tamarisk and Russian olive distribution models along the Colorado River and its’ main tributaries. Change in riparian vegetation for Colorado River Basin was analyzed, finding an overall increase in riparian vegetation between 2006 and 2016. Also, an evaluation of the change map in known regions of tamarisk management showed that our models did identify a substantial decrease in tamarisk. The results of this study are a promising next step for project partners to utilize remote sensing to monitor the efficacy of management efforts throughout the Colorado River Basin and inform future management strategies.
