To examine potential influence of tributaries on riparian habitat complexity along ~216 km of the Colorado River in Utah and ~300km of the Dolores River in Colorado and Utah, we first classified fluvial features and land cover of the bottomland on remotely sensed imagery. We then examined riparian and geomorphic patterns within the near channel zone with variably-sized spatial units. We used supervised image classification to create a 2-m resolution map of the primary land cover types within bottomlands of the Colorado and Dolores rivers, including two anthropogenic classes, four vegetation classes, bare ground, water and shadow. We selected these cover classes as major vegetation and land cover types that could...

We will develop an approach to identify fire refugia in Rocky Mountain ecosystems of the U.S. and Canada then test the function of refugia for biodiversity conservation under current and future climate/fire scenarios. Our products will be designed to inform decision-making in land/easement acquisition, identification of critical areas for maintaining landscape and process connectivity/permeability, and extension of the temporal context for spatial conservation decision making. The approach will be testable for transferability to other locations and ecosystems.FY2013Objectives:The proposed project will provide a science application for focused resource conservation by developing and testing the concept of refugia...

Stream flow in the Colorado River and Dolores River corridors has been significantly modified by water management, and continued flow alteration is anticipated in future decades with projected increases in human water demand. Bottomland vegetation has been altered as well, with invasion of non-native species, increases in wildfire and human disturbance, and currently, rapid shifts in riparian communities due to biological and mechanical tamarisk control efforts. In light of these conditions, land managers are in need of scientific information to support management of vegetation communities for values such as healthy populations of sensitive fish and wildlife species and human recreation. We propose to address these...
