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?...

The University of California, Davis in partnership with the Navajo Nation is partnering with the Southern Rockies LCC to provide estimates of habitat connectivity for focal species on the Navajo Nation and adjacent lands that the tribe wishes to incorporate into planning and implementation of adaptive management. The project will derive habitat variables as inputs for connectivity models, and model outputs likely will include habitat quality and conductance. Species-specific models will be mathematically integrated to permit probabilistic statements about simultaneous connectivity for two or more species. The spatial data developed on wildlife distributions and habitat to model connectivity and, ultimately, viability...

Museum of Northern Arizona, Inc. will leverage tools previously developed by the Springs Stewardship Initiative to help resource managers in the southwestern U.S. collect, analyze, report upon, monitor and archive the complex and interrelated information associated with springs and spring-dependent species in the region. The information will be compiled and made readily available online. The Museum will further develop interactive online maps and climate change risk assessment tools of springs-dependent sensitive plant and animal species.

The purpose of this data set is support resource allocation decisions (i.e. where to invest conservation effort) within the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative. The Condition Index ranks pixels (250-m) according to how well they meet the Desired State for the Grasslands habitat system, which is described qualitatively and quantitatively in the GCPO LCC’s draft Integrated Science Agenda (v4). Higher values indicate sites closer to the Desired State. Value of 1 indicates areas appropriate for restoration but currently under an alternative land use (i.e. potential habitat). Please see PDF file in the Forested Wetland folder in the Blueprint Gallery at https://gcpolcc.databasin.org/ for...
Static flood inundation boundary extents were created along the entire shoreline of Lake Ontario in Cayuga, Jefferson, Monroe, Niagara, Orleans, Oswego, and Wayne Counties in New York by using recently acquired (2007, 2010, 2014, and 2017) light detection and ranging (lidar) data. The flood inundation maps, accessible through the USGS Flood Inundation Mapping Program website at https://www.usgs.gov/mission-areas/water-resources/science/flood-inundation-mapping-fim-program, depict estimates of the areal extent and water depth of shoreline flooding in 8 segments corresponding to adjacent water-surface elevations (stages) at 8 USGS lake gages on Lake Ontario. This item includes data sets for segment A - Lake Ontario...

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...

Despite the lack of surface flows, the Colorado River riparian corridor in Mexico has proven to be ecologically resilient. Floods in the 1980s and 90s in the region brought back large swaths of native riparian habitat, which still persist today in some areas along the river. Because the historic floodplain is extremely important for agricultural production and therefore the local economy, habitat maintenance must be integrated with continued utilization of lands and water for this purpose.The riparian, marsh, and open-water areas found in Reach 4 provide critical habitat for both migratory and resident riparian bird species. Due to its ecological importance, the riparian corridor and Reach 4 in particular have been...

This decision support tool provides spatially explicit information pertaining to modeled wildlife connectivity value across major roads, total wildlife mortality counts along major roads, carnivore mortality counts along major roads, the extent to which wildlife connectivity value and road mortality align, and potential priority sites for mitigation of road impacts on wildlife from diverse stakeholder perspectives. In the report accompanying this map document, we also discuss potential opportunities for diverse stakeholders (including departments of transportation, state and federal land managers, land trusts, citizen groups, and conservation organizations with a variety of missions) to engage in and contribute...

The North Pacific Forest Landscape Corridor and Connectivity Project utilized a landscape connectivity simulator (UNICOR) and a genetic simulation program (CDPOP) to model the functional (dispersal and genetic) connectivity in the North Pacific Landscape. The outputs from these programs indicated areas with high potential for landscape and genetic isolation and low probability of dispersal and colonization. In addition, this project was designed to provide spatially-explicit predictions of current and potential future patterns of fragmentation, prioritization of keystone corridors for protection and enhancement, and identification of places that may require habitat restoration or assisted migration to maintain viability....

This dataset features inundated areas connected to the main channel at discharges from 15,000 cfs to 95,000 cfs. The spatial extent for floodplain inundation modeling in the lower Trinity River was from Romayor, Texas, to approximately Moss Bluff, Texas. River sections were modeled using steady flow conditions. For the upper section, discharge and stage were both available for the two gages (Romayor USGS 08066500 and Liberty USGS 08067000). For the lower section, the Moss Bluff gage (USGS 08067100) is tidally-influenced, so gage height didn’t correspond to upstream changes in discharge. To model river stage specific inundation for the upper section, discharge for each Landsat 8 overpass date was entered as the upstream...

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...
