There is a need to understand how alteration of physical processes on the Rio Grande River have impacted aquatic biota and their habitats, and a need to predict potential future effects of climate change on biotic resources in order to prescribe research and management activities that will enhance conservation of aquatic species. We propose a project with the goal of developing monitoring recommendations and identifying research needs for aquatic ecological resources in the Big Bend region of the Rio Grande. This goal will be targeted by synthesizing and analyzing available data and literature for aquatic species in the project region. In particular, we will work to develop time series of abundance and population...

FY2014Although the future of sage grouse depends on the future of sagebrush, we have limited ability to anticipate impacts of climate change on sagebrush populations. Current efforts to forecast sagebrush habitat typically rely on species distribution models (SDMs), which suffer from a variety of well-known weaknesses. However, by integrating SDMs with complementary research approaches, such as historical data analysis and mechanistic models, we can provide increased confidence in projections of habitat change. Our goal is to forecast the effect of climate change on the distribution and abundance of big sagebrush in order to inform conservation planning, and sage grouse management in particular, across the Intermountain...

Greater sage-grouse genetic connectivity is essential to the species persistence across the Great Northern landscape; without such connectivity the greater sage-grouse may suffer the same fate as many other related species of grouse, which disappeared from the middle and eastern portion of the United States due to loss of habitat coupled with inbreeding depression. To prevent isolation in the face of energy development and other landscape changes it is essential that we evaluate both fine-scale connectivity and assign relative importance to different leks (breeding populations) on the landscape. This massive task cannot be accomplished with existing tools and maps; fortunately, advanced molecular genomic analyses...

FY2010In addition to regional Science and Traditional Ecological Knowledge projects that the Great Basin LCC (GBLCC) supports, GBLCC staff lend technical expertise to a range of projects and have contributed to important regional publications on a range of subjects. These publications range in type from textbooks, to management-oriented science and conservation plans, to scientific papers and have covered subjects like wind erosion following fire, soil microbiota response to drought, plant community resilience to invasive species, and alpine plant communities. In many cases these publications form foundations for scientifically-informed management strategies across the Great Basin.

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,...

The proposed large-scale collaborative research project will provide the first thorough assessment of the effects of pion-juniper woodland treatments on the Pinyon Jay, a species undergoing rapid population declines according to the BBS. The results of this multi-state study will provide land management agencies critical information about impacts of woodland management on the species and significant, novel data about habitat use and specific habitat preferences. These data will allow land managers to better understand the needs of the species and inform how future management practices can be implemented to reduce or mitigate negative impacts. Without these data, land management agencies and the conservation community...

FY2011Aspen populations are in decline across western North America due to altered fire regimes, herbivory, drought, pathogens, and competition with conifers. Aspen stands typically support higher avian biodiversity than surrounding habitats, and maintaining current distributions of several avian species is likely tied to persistence of aspen on the landscape. We are examining effects of climate change on aspen and associated avian communities in isolated mountain ranges of the northern Great Basin, by coupling empirical models of avian-habitat relationships with spatially-explicit landscape simulations of vegetation and disturbance dynamics (using LANDIS-II) under various climate change scenarios. We are addressing...

In response to the rapid and dramatic hydroecological deterioration of the Rio Grande through Big Bend, the Big Bend Conservation Cooperative (BBCC), a multi-disciplinary group of natural resource agencies, research institutions, and conservation organizations have been organizing and implementing a wide range of river rehabilitation, scientific research activities and climate change initiatives. More recently, the Basin and Bay Expert Science Team, part of an environmental flows initiative by the state of Texas, is using best available science to recommend environmental flow regimes for the major rivers of Texas. Limited understating of the sediment dynamics of the Rio Grande and riparian vegetation change hinders...

Existing stream temperature data were compiled from numerous federal, state, tribal, and private sources to develop an integrated regional database. Spatial statistical models for river networks were applied to these data to develop an accurate model that predicts stream temperature for all fish-bearing streams in the US portion of the GNLCC. Differences between model outputs for historic and future climate scenarios were used to assess spatial variation in the vulnerability of sensitive fish species across the GNLCC.FY2011Objectives: Develop a regional stream temperature model that incorporates important climate drivers, wildfire/riparian conditions, and geomorphic factors; Use the model to understand and predict...
