The USGS Southeast Ecological Science Center (SESC) Nonindigenous Aquatic Species (NAS) database provides records of sightings and capture data of non-native (introduced) aquatic species over the entire the United States (Benson 1999). For areas within the SALCC region, the NAS currently contains records dating back to 1885 for over 200 nonindigenous plant and animal species. This project seeks to utilize these data along with new GIS-based data on current and future (e.g. SLEUTH) landscape and climate parameters to develop models of invasive species introductions and dispersal across the SALCC region. Both multi- and single species models will be considered in these analyses. We will then utilize a formal decision-analytic...
There are myriad barriers to aquatic connectivity beyond dams, with culverts at road crossings primary among them. UGA will lead the effort to develop a database of these non-dam blockages and model the likelihood that each is a barrier to fish movement, including mussel hosts. This process, described in more detail below, will result in a GIS point layer with numeric attributes that describe the likelihood that any given crossing is a blockage to fish passage. This data will be incorporated into the dam database to produce a database of all known and potential barriers in the region. This unified database will form the unit of analysis for the subsequent connectivity assessment in which each of the barriers will...
The South Atlantic LCC is seeking technical assistance in the testing process for their newly chosen terrestrial natural resource indicators (http://www.southatlanticlcc.org/indicators). For each ecosystem and the three indicators within each ecosystem, South Atlantic LCC staff and collaborators are seeking to answer the following: 1) How well does each indicator represent a variety of organisms and ecological attributes within the ecosystem and throughout a major portion of the LCC? What does it miss? 2) How well does combination of three indicators within each ecosystem represent a variety of organisms and ecological attributes within the ecosystem and throughout a major portion of the LCC? What do they miss?...

Currently, maintaining appropriate flows to support biological integrity is difficult for larger riverine ecosystems. Climate change, through increased temperature, reduced rainfall, and increased rainfall intensity, is expected to reduce water availability and exacerbate the maintenance of ecological flows in the Arkansas-Red River basin. Understanding the nexus among climate change effects on streamflow, water quality, and stream ecology for watersheds in the Arkansas-Red River Basin can be achieved using currently existing science and technology. This nexus approach will strengthen adaptive-management strategies that focus on shared ecosystem conservation watershed targets. This approach will provide natural-resource...

Within the time frame of the longevity of tree species, climate change will change faster than the ability of natural tree migration. Migration lags may result in reduced productivity and reduced diversity in forests under current management and climate change. We evaluated the efficacy of planting climate-suitable tree species (CSP), those tree species with current or historic distributions immediately south of a focal landscape, to maintain or increase aboveground biomass, productivity, and species and functional diversity. We modeled forest change with the LANDIS-II forest simulation model for 100 years (2000–2100) at a 2-ha cell resolution and five-year time steps within two landscapes in the Great Lakes region...
This project used species distribution modeling, population genetics, and geospatial analysis of historical vs. modern vertebrate populations to identify climate change refugia and population connectivity across the Sierra Nevada. It is hypothesized that climate change refugia will increase persistence and stability of populations and, as a result, maintain higher genetic diversity. This work helps managers assess the need to include connectivity and refugia in climate change adaptation strategies. Results help Sierra Nevada land managers allocate limited resources, aid future scenario assessment at landscape scales, and develop a performance measure for assessing resilience.

This project will develop a flexible geographic information system (GIS)-based database (GIS-Hydroads) that can be integrated with a regional hydrologic model developed at the University of Washington (UW) to aid in decision making related to road infrastructure (initially culverts) associated with flooding risks under climate change. GIS-Hydroads will be designed in a modular fashion in collaboration with the National Park Service (and the US Forest Service), and be expandable with future technical capabilities and transferable throughout the western US. Proof-of-concept applications of GIS-Hydroads will be presented in a representative basin along the west slope of the North Cascade mountains of Washington, where...

Sea level rise caused by climate change is an ongoing phenomenon and a concern both locally and worldwide. Low-lying coastal areas are particularly at risk to flooding and inundation, affecting a large proportion of the human population concentrated in these areas as well as natural communities-particularly animal species that depend on these habitats as a key component of their life cycle. While more local, state, and federal governments have become concerned with the potential effects that predicted sea levels will have on their communities and coastal landscapes, more information is needed on the potential effects that changes in sea level will have on coastal habitats and species.

Prairie ecosystems and the grassland birds that rely on them for habitat may be particularly vulnerable to rapid changes in climate. Extensive portions of prairie have already been lost due to agriculture and urbanization, and as a result grassland birds have declined more than any other bird group in the last four decades. Now, climate change could exacerbate existing threats to these birds as temperatures in certain prairie ecosystems are expected to rise and extreme weather events, such as drought, could become more common. The goal of this project was to develop a framework to identify demographic sensitivities and assess the vulnerability of grassland bird species to future climate change. To do so, the researchers...

While 21st century temperatures are projected to increase in Puerto Rico and the broader U.S. Caribbean (whose geography is contained within the Caribbean Landscape Conservation Cooperative, or CLCC), the low variability and already high annual average temperatures suggest that the largest climate-related impact on ecosystems and water resources is more likely to be through changes in the timing, pattern, and availability of moisture. The development of adaptation strategies that respond to anthropogenic climate change for the CLCC, and particularly for Puerto Rico, is currently hindered by the lack of local-scale climate scenarios that resolve the complex topographical and meso-scale climate features that will...

Executive Summary: Evolution of policies that guide operation of individual reservoir systems begins with a relative flurry of activity associated with building of dams. Over perhaps a ten year period, operations are proposed in anticipation of construction, implemented when a dam is complete, and then modified as the effects, capabilities, and limitations of the project become better understood. After these initial adjustments, the policy process slowly begins to simmer. Operational changes are the driven by short-term influences that are largely episodic (e.g. droughts and floods) and long-term influences (e.g. social and economic factors) that affect operations more gradually.

The importance of riparian ecosystems in semiarid and arid regions has generated interest in understanding processes that drive the distribution and abundance of dominant riparian plants. Changes in streamflow patterns downstream of dams have profoundly affected riparian vegetation composition and structure. For example, in the southwestern United States, flow regulation has contributed to the replacement of many riparian forests historically dominated by the native Populus fremontii (Fremont Cottonwood) and Salix gooddingii (Goodding’s Willow) by the exotic species Tamarix spp. (Salt Cedar). The proposed project will help guide reservoir release decision making to enhance downstream recruitment of native cottonwood...

The focus of the first Midwest Urban Conservation Workshop was to understand the challenges stakeholders are facing, define the needs for collaboration and best management practices, establish a platform for conversation focusing on learning from each other and creating an opportunity for collaboration on new initiatives through a collective impact. The workshop was framed around the idea of making a collective impact, as what happens upstream directly affects what happens downstream. Over 40 participants included scientists, urban planners, and state, federal, private and nonprofit organizations with interests in creating a network of professionals interested in the value of our waterways. We envision a world where...

Unconventional oil development in the Bakken shale region has increased rapidly as a result of new technologies. This region also supports a particularly high density and diversity of grassland bird species, which are declining across North America. We examined grassland bird response to unconventional oil extraction sites (i.e. developed with hydraulic fracturing and horizontal drilling) and associated roads in North Dakota. Our goal was to quantify the amount of habitat that was indirectly degraded by oil development, as evidenced by patterns of avoidance by birds. Grassland birds avoided areas within 149 m of roads (95% CI: 4 – 294 m), 267 m of single-bore well pads (95% CI: 157 – 377 m), and 150 m of multi-bore...

The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. NLCD supports a wide variety of Federal, State, local, and nongovernmental applications that seek to assess ecosystem status and health, understand the spatial patterns of biodiversity, predict effects of climate change, and develop land management policy. However, access to NLCD products for the USGS community and the public is a concern due to large file sizes, limited download options, and the expectation that users must download and analyze multiple land cover products in order to answer even basic land cover change questions. Therefore, the goal of the NLCD Evaluation, Visualization...
FY2013The increase in large wildfires at a time when habitat for Greater Sage Grouse and other species dependent on big sagebrush has also increased has led to substantial needs for big sagebrush seeds. Significant decisions on which sagebrush seed to use and on management treatments that affect competing herb layers on the same restoration sites affect the trajectory of habitat.This project will evaluate how seed source, specifically genotype and climate-of-origin, interact with landscape-scale and replicated treatments (fencing, herbicide application, mowing, and seeding).

A recent (2008-2012) outbreak of Geometrid moths has decimated subsistence berry harvest in South Central Alaska. This project will develop a risk model to predict where subsistence berry plants will be most resistant to Geometrid attack. The model will be used to identify areas where berry improvement silvicultural treatments are most likely to be successful.
