This dataset represents the variety (count of unique classes within 0.5 ha) of vegetation communities, river channel and bare areas (often sand bars) 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...

We mapped surface water from high resolution photography taken on September 16, 2010, at a stream flow of 96.5 m3/s (3,410 ft3/s, Cisco gage). We subdivided surface water into six categories: primary channel, secondary channel, split flow channel, backwater, isolated pool, and tributary channel, similar to that of fish habitat methods used extensively in Oregon. Channel types that are not primary channel are considered ‘off-channel’.

This is a habitat suitability model for bat feeding in the Colorado River bottomland in Utah. The model incorporates distance to water, stillness of adjacent water, and the variety of dominant cover types within 0.5 ha radius. See Open File Report, Rasmussen and Shafroth, Colorado River Conservation Planning for geoprocessing details.

This dataset represents relative patch size of riparian 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. 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 snakes that prefer the rocky boundaries of the bottomland of the Colorado River in Utah. The model incorporates distance to water, distance to the bottomland boundary, diversity of woody cover, and diversity of cover types within a 50 sq meter areas. See Open File Report, Rasmussen and Shafroth, Colorado River Conservation Planning for geoprocessing details.

With the help of local and regional natural resource professionals, we developed a broad-scale, spatially-explicit assessment of 146 miles (~20,000 acres) of the Colorado River mainstem in Grand and San Juan Counties, Utah that can be used to support conservation planning and riparian restoration prioritization. For the assessment we: 1) acquired, modified or created spatial datasets of Colorado River bottomland conditions; 2) synthesized those datasets into habitat suitability models and estimates of natural recovery potential, fire risk and relative cost; 3) investigated and described dominant ecosystem trends and human uses, and; 4) suggested site selection and prioritization approaches. Here, we make available...

This data set shows the extent of the Colorado River Conservation Planning project bottomland area as delineated by topography and vegetation, The bottomland area is subdivided into 1 km polygons measured from the upstream project boundary.

This map shows areas covered by the high flow 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. Area not covered by 2011 flow is represented by bottomland boundary.

This dataset represents the density of mesic shrub cover (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 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.

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.
