In the drier, mid- and low-elevation portions of the Southern Rockies LCC, Fremont cottonwood represents the only native vegetation of tall stature, and cottonwood-dominated woodlands provide critical habitat for a large array of neotropical migratory birds and other animals. These woodlands likely dominated alluvial reaches of all streams where a snowmelt-driven spring flood was the major factor driving geomorphic and vegetation dynamics. These woodlands were also among the first habitats to undergo transformation as the regions land and water resources were developed.The PI coauthored a paper (Andersen et al. 2007) on assessing the amount of native Fremont cottonwood forest remaining on floodplains in 26 subbasins...

Colorados Front Range represents a region of the Southern Rockies LCC that is both ecologically and economically significant. It is home to the majority of Colorados residents, including the major population centers of Denver, Fort Collins, Boulder, and Colorado Springs, and provides critical ecosystem services such as clean and abundant water, wildlife habitat, recreation opportunities, and aesthetic values to the rest of the state. Ponderosa pine (Pinus ponderosa) dominated forests span the majority of the Front Range mountains and foothills, covering approximately 700,000 acres of the Front Range landscape between 5000 and 8500 ft elevation. The lower-montane zone ponderosa pine forests (~5500-7000 ft) form the...

In the desert Southwest, changes in species composition, abundance, and distribution that may occur with climate change have significant implications for management of natural resources. These changes include: the extirpation or introduction of species, losses of biodiversity, shifts in structure and function of ecosystems and the services they provide, changes in wildlife habitat, invasion of non-native species, and changes in fire regimes. For planning, mitigation, and adaption, land managers would be greatly aided by knowing, in advance, which plant species, functional types, and assemblages will change in response to climate change so that monitoring and mitigation measures can focus on those resources.

This project will build an SR LCC catalog inside of the USGS-sponsored ScienceBase scientific data and information management platform, provide the ability for partner organizations to maintain and contribute to an SR LCC0specific work environment in ScienceBase, and provide stewardship and data integration coordination for the SR LCC partners.FY2012This project will build an SR LCC catalog inside of the USGS-sponsored ScienceBase scientific data and information management platform, provide the ability for partner organizations to maintain and contribute to an SR LCC0specific work environment in ScienceBase, and provide stewardship and data integration coordination for the SR LCC partners.

The purpose of this agreement is to initiate SRLCC-wide data discovery, cataloging, and general GIS analysis to characterize the landscape across the SRLCC geographic area. The SRLCC has identified the need for a data management activity to support all aspects of data discovery, dissemination, cataloging, and analysis. An existing agreement between FWS and the USGS provides for an SRLCC catalog inside the U.S. Geological Survey-sponsored ScienceBase scientific data and information management platform and provides the ability for partner organizations to maintain and contribute to this work environment. Initial information and data discovery process will compile existing resources in the ScienceBase SRLCC data portal...

Streamflows in late spring and summer have declined over the last century in the western U.S. and mean annual streamflow is projected to decrease by six to 25% over the next 100 years. In arid and semi-arid regions of the western US, it is likely that some perennial streams will shift to intermittent flow regimes in response to climate-driven changes in timing and magnitude of precipitation, runoff, and evaporation. The project will address the following two research question: how will small stream (1st-3rd order) low flow hydrology be impacted by predicted longer, drier summers in the Upper Colorado River Basin under climate change and in turn, what will be the resulting impacts on riparian plant communities?...

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...
