Set of test parameters for representing channel habitat complexity at low flow (2010, 2,410 cfs at Cisco).

Model of habitats for rocky fringe snakes
thumbnail
Revised model for rocky fringe snakes 8-6-2013
thumbnail
This is a model showing general habitat diversity, including both the structural and cover type diversity. See Open File Report, Rasmussen and Shafroth, Colorado River Conservation Planning for geoprocessing details.

A model of bat feeding habitats
thumbnail
A model of habitats for bat feeding.
thumbnail
This map shows stillness of water near bank vegetation within 15 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 publically 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.
thumbnail
These layers show the relative abundance of native, non-native and tree cover types as mapped for the Colorado River Conservation Planning Project. Relative abundance (Dominant, Common, Mapped by Sparse and Not Mapped) is determined by the listing of cover types per patch.
thumbnail
Opportunities for bat watering at high and low flows.
thumbnail
This is a habitat suitablilty model riparian understory species in the Colorado River bottomland in Utah. The model incorporates the density of shrubs, the number of shrub species present, and the stillness of adjacent 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 proximity to human caused ignition sources (campgrounds and roads). See Open File Report, Rasmussen and Shafroth, Colorado River Conservation Planning, for geoprocessing details.
thumbnail
This set of maps shows relative habitat diversity (complexity) as it relates to the number of different dominant cover types are found in 1 hectare, and the number of structural types found in 1 hectare. Component layers are included, as are layers of channel boundaries, reaches, and bottomland kilometers.
thumbnail
This set of maps shows relative habitat quality for snakes that prefer the rocky outside margin of the bottomland area. Component layers (type and count of cover types, distance to bottomland boundary and distance to permanent water) are included, as are associated layers of channel boundaries, reaches, and bottomland kilometers.
thumbnail
This is a model of the relative costs of restoration for of vegetation communities of the Colorado River bottomland in Utah. The model incorporates the prevalence of woody and herbaceous non-native species, difficulty of access to bottomland areas, and presence of woody and/or herbaceous non-native speices. See Open File Report, Rasmussen and Shafroth, Colorado River Conservation Planning for geoprocessing details.
thumbnail
This is a model of the potential for natural recovery in vegetation communities of the Colorado River bottomland in Utah. The model incorporates the prevalence of native species, areas inundated in high flow conditions, and the prevalence of non-native species. See Open File Report, Rasmussen and Shafroth, Colorado River Conservation Planning for geoprocessing details.
thumbnail
This set of maps shows relative habitat quality for species that prefer open areas. Component layers (herbacoeus areas, distance to high water) are included, as are associated layers of channel boundaries, reaches, and bottomland kilometers.
thumbnail
Models of understory and overstory habitats, with alternate models with tamarisk penalties for each.
thumbnail
Fish comments from Expert Workshop. Does not include fish use. That layer is separate.
thumbnail
This is a habitat suitablilty 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.
thumbnail
This is a habitat suitablilty 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.
