This dataset represents the prevalence of tamarisk as mapped along the Colorado River bottomland from the Colorado state line (San Juan and Grand Counties, Utah) to the southern Canyonlands NP boundary, as of September 2010. photos, this cover layer reflects conditions that existed when the imagery was collected (September, 2010). This mapping was conducted as part of the Colorado River Conservation Planning Project, a joint effort between the National Park Service, The Nature Conservancy, US Geological Survey, Bureau of Land Management, and Utah Forestry Fire and State Lands.

This dataset represents the prevalence of tamarisk (tamarisk penalty) as mapped along the Colorado River bottomland from the Colorado state line (San Juan and Grand Counties, Utah) to the southern Canyonlands NP boundary, as of September 2010. Traditional image interpretation cues were used to develop the polygons, such as shape, size, pattern, tone, texture, color, and shadow, from high resolution, true color, aerial imagery (0.3m resolution), acquired for the project. Additional, public available aerial photos (NAIP, 2011) were used to cross-reference cover classes. As with any digital layer, this layer is a representation of what is actually occurring on the ground. Errors are inherent in any interpretation of ground qualities. Due to the "snapshot" nature of the aerial photos, this cover layer reflects conditions that existed when the imagery was collected (September, 2010).

This is a fire risk model for riparian trees on the Colorado River bottomland in Utah. The model incorporates the prevalence of riparian trees and tamarisk, and proximity to human caused ignition sources (campgrounds and roads). See Open File Report, Rasmussen and Shafroth, Colorado River Conservation Planning, for geoprocessing details.

This dataset represents the relative abundance of non-native, woody cover types in vegetation patches, as mapped from high resolution imagery from 2010.

This is a fire risk model for riparian trees on the Colorado River bottomland in Utah. The model incorporates the prevalence of riparian trees and tamarisk, and considers only natural fire ignitions (lightning).
