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...

Water resource managers rely on hydrologic planning and decision-making models to understand and evaluate current and future water operations in the face of endangered species needs, drought, and climate change. Current climate change projections, such as those used in the West-Wide Climate Risk Assessment programs, are trending toward more extreme instances of drought within the Southern Rockies LCC region. Accurately estimating agricultural water consumption both under present conditions and under modeled future scenarios will help water resource managers project how much water might be available for allocation toward current ecological projects. It will also improve their understanding of the challenges a more...

By collaborating with water managers and combining climate modeling and paleoclimate methods, the project team will incorporate prediction tools to assess risk of extreme wet/dry climate conditions for the next 10-15 years (i.e. decadal prediction). Our target area is the Wasatch Range Metropolitan Area that includes Salt Lake City one of the largest population centers within the Southern Rockies LCC. We will focus on projecting future water availability and quality with a specific goal for decadal prediction. The project team has partnered with numerous water agencies in the Wasatch Range who have made in-kind contributions towards this project. This partnership guarantees that the results will be disseminated,...

Streamflow and basin-characteristic data are needed for a variety of scientific and managerial applications, including estimation of flow in ungaged basins and hydro-ecological classification of rivers. These data are collected by a variety of organizations, usually on a state-by-state basis. The existing network of streamflow gaging stations within the SRLCC provides much useful data. However, because it is not feasible to operate gaging stations at all locations where planning, structure design, or water-management decisions will be made, resource managers, scientists, and stakeholders need a reliable means to project information from gaged to ungaged locations using standard statistical techniques. The spatial...

The Gunnison Climate Working Group is a chartered partnership of 14 public and private organizations in Colorados Upper Gunnison Basin. The Southern Rockies LCC (SRLCC) funded The Nature Conservancy to complete a comprehensive vulnerability assessment identifying species and ecosystems most at risk from climate change. The assessment included a set of habitat adaptation strategies for priority species, such as the Gunnison sage-grouse. As a final product, local demonstration projects were designed and installed.The financial support and partnership provided by the SRLCC was critical to the Gunnison Climate Working Groups success and progress towards addressing climate change. As a direct result of the SRLCC involvement,...

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?...

This project aims to improve seasonal water supply forecasts on the Upper Rio Grande River basin and, in doing so, help to minimize the substantial costs associated with erroneous forecasts and related sub-optimal allocations of water for surface irrigation, groundwater recharge and endangered specifies management. Erroneous seasonal water supply forecasts in the Upper Rio Grande River basin have a profound impact on water management, agricultural production and economic vitality.The specific goals of this project are to: Develop state-of the art precipitation and snowpack monitoring products through the use of experimental radar, surface observations and land data assimilation systems Improve the spatial and...

The project will result in recommendations for a decision support platform that links coarse and fine scale tools and for improving the Colorado River Simulation System (CRSS) as the central analytical tool for basinwide water supply planning. The work will largely be accomplished by assembling an exceptionally qualified team in cross-disciplinary, water management decision support systems, in the CRSS, and in two finer scale water management decision supports within the basin and by responding to an advisory group oflead water management agencies.The project will immediately build on the Colorado River Basin Water Supply and Demand Study being led by the U.S. Bureau of Reclamation, will extend the interface between...

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...

Rivers in the SRLCC differ from one another in flow characteristics, levels of regulation, and vulnerability to wildfire; characteristics that will be influenced by climate change (Seager et al. 2007, Mortiz et al. 2012). An understanding of how changes in streamflow and wildfire frequency will affect structure of live and dead woody vegetation is needed to for managers assess the vulnerability of riparian obligate species to climate change. We are developing stochastic transition models for cottonwood trees and snags along the Middle Rio Grande by modifying Lytle and Merritts (2004) stage-structured cottonwood population model. By incorporating influences of flood and wildfire into stage transition rates, we can...

The overall project goal is to understand and model the watershed impacts of forest restoration actions (thinning, prescribed fire) and climate change on the hydrologic function, particularly with respect to (1) changes in soil moisture and water yield during snowmelt, (2) inter-annual and directional changes in stream water quality, and (3) the resulting impacts on watershed management for wildlife species threatened by disturbance and climate change.Specifically, we will: use known relationships of forest structure on snow-water equivalent (SWE) values and processes of sublimation (ablation), infiltration and run-off in the Jemez Mountains of northern New Mexico to model forest-stand restoration prescriptions,...

Land managers have incorporated threats to biodiversity for nearly two decades, but very few efforts have included threats from future conditions and fewer still have assessed vulnerability to climate change. This project will address two themes: 1) providing foundational information about habitat fragmentation and connectivity and 2) identifying the degree of vulnerability of key habitats to climate change.For development of understanding broadextent, a landscape-level pattern of climate change is an important complement to approaches to estimate rangeshifts for certain key focal species. Ecological system types (i.e. coarsefilters) are widely used in conservation planning because they contain valuable resources...

Information on the sources of sediment production and amount is necessary to better understand the relationship between landscape-scale ecosystem drivers (fire, large-scale invasive species removal, recreation, oil and gas development, and grazing) and sediment loading in rivers, streams, and reservoirs. An improved understanding of the sources of sediment production and the contribution of each source to total sediment load would enable resource managers to better locate and design conservation strategies to reduce sediment loading, and improve water quality, native fish habitats, and upland vegetation cover.This project will conduct an erosion and sediment supply analysis in a portion of the Upper Green River...
