This dataset represents the number of mesic shrub species (averaged per 1.0 ha) 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. 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 a penalty for tamarisk abundance (averaged per 1.0 ha) 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. 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 a map showing distances from the Colorado River bottomland boundary between the Utah Colorado border and the upper pool of Lake Powell, Utah (146 miles). The bottomland boundary was mapped from publicly available NAIP imagery flown on June 28, 2011, and from project imagery flown in 2010. The bottomland boundary includes tributary channels and associated alluvial deposits, as those features are part of potential project areas and are important for habitat. The boundary extends only a short distance up larger tributaries (e.g. Dolores and Green Rivers)

This is a habitat suitability model for bat watering in the Colorado River bottomland in Utah during high flow conditions. The model combines the presence of preferred slow water channel types (backwaters, isolated pools and tributary mouths), with cover types amenable to bat overflights and drinking 'on-the-wing'. See Open File Report, Rasmussen and Shafroth, Colorado River Conservation Planning for geoprocessing details.
thumbnail
This is a model showing estimated habitat suitability for open land (grassland) species, or those that burrow, or prey on species that burrow. The model incorporates two factors: the relative abundance of non-woody cover types and the distance from high water.
thumbnail
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). See Rasmussen and Shafroth, Colorado River Conservation Planning, for geoprocessing details.
thumbnail
This is a habitat suitability model for riparian overstory species in the Colorado River bottomland in Utah, and includes a penalty for abundance of tamarisk which may limit habitat quality. The model incorporates the prevalence of trees, complexity of woody structure, quality of canopy, and tree patch size. See accompanying publication for data processing details.
thumbnail
This dataset represents the average number of cover types listed per patch, as calculated within a 50 sq meter radius. 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 native species 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. 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 is a habitat suitability model for riparian overstory species in the Colorado River bottomland in Utah. The model incorporates the prevalence of trees, complexity of woody structure, quality of canopy, and tree patch size. See accompanying publication for data processing details.

This dataset represents the penalty for thin canopy trees 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....

This maps shows the distances away from the channel boundary of the Colorado River mainstem between the Utah Colorado border and the upper pool of Lake Powell, Utah (146 miles). The channel boundary was mapped from public available NAIP imagery flown on June 28, 2011, when the river flow was 886 m3/s at the Cisco gage. The channel is subdivided into channel types: main channel, secondary channel, backwater, isolated pool and tributary channel.

This map shows habitats within 50 m of the channel boundary (2011) of the Colorado River mainstem between the Utah Colorado border and the upper pool of Lake Powell, Utah (146 miles). The channel boundary was mapped from public available NAIP imagery flown on June 28, 2011, when the river flow was 886 m3/s at the Cisco gage. The channel is subdivided into channel types: main channel, secondary channel, backwater, isolated pool and tributary channel.

This dataset represents the relative abundance of non-native, herbaceous cover types in vegetation patches, as mapped from high resolution imagery from 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 maps shows distances away from the channel boundary of the Colorado River mainstem. The channel boundary was mapped from public available NAIP imagery flown on June 28, 2011, when the river flow was 886 m3/s at the Cisco gage. The channel is subdivided into channel types: main channel, secondary channel, backwater, isolated pool and tributary channel. Closer to the channel often non-preferred habitat for burrowing; 50-100 m is moderately non-preferred; >100 m preferred.

This dataset represents the average number of woody cover height classes listed per patch, as calculated within a 50 sq meter radius. 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 set of maps shows relative habitat quality for bat watering. Component layers (distance to water, vegetation cover types, open flight areas) are included, as are complementary layers of channel boundaries, reaches, and bottomland kilometers.
thumbnail
Vegetation and water surface cover was mapped for the entire Colorado River bottomland within the project area (Utah/Colorado border to lower boundary of Canyonlands National Park) using high resolution photographs flown in September of 2010. Vegetation cover was mapped initially by the National Park Service and heavily edited for use in the project. Channel mapping was initially done by John Dohrenwend, with polygons heavily edited for use in the project. Cover was identified as most prominent (Dominant), next most prominent (Common), next most prominent (Present) and last most prominent (also Present). Codes for cover types and cover type descriptions are available within the dataset and metadata.
