While habitat selection and population estimates are well documented for spring migrating birds in the central Platte River system, little information or monitoring efforts on the North Platte River exist, particularly for the multiple priority bird species known to be present. Most conservation partners deliver habitat programs in the region with limited information and a lack of a landscape prioritization tools. In order for conservation delivery to be more effective and efficient in utilizing limited funds, a decision support tool is critical so that priority species habitat needs are being addressed through appropriate restoration/management strategies in the correct geography at multiple scales. We propose...

Comprehensive wetland inventories are an essential tool for wetland management, but developing and maintaining an inventory is expensive and technically challenging. Funding for these efforts has also been problematic. Here we describe a large-area application of a semi-automated processused to update a wetland inventory for east-central Minnesota. The original inventory for this area was the product of a laborintensive, manual photo-interpretation process. The present application incorporated high resolution, multi-spectral imagery from multiple seasons; high resolution elevation data derived from lidar; satellite radar imagery; and other GIS data. Map production combined image segmentation and random forest classification...
The Florida Fish and Wildlife Conservation Commission (FWC) has been heavily involved in contributing to and shaping the three LCC’s that include Florida, with special emphasis on the Peninsular Florida Landscape Conservation Cooperative (PFLCC), which falls entirely within the state of Florida. Substantial resources from multiple partners will be required to establish and maintain the PFLCC. FWC will partner with the Service and through this Cooperative Agreement will work in collaboration with the Service to assume roles and responsibilities of the Science Coordinator and Communication Coordinator for the PFLCC.These products represent the cooperative agreement and award letters for the ongoing support for the...

Under this agreement, the Mr Hankla developed and facilitated implementation of pilot programs addressing the conservation objectives of the PFLCC within the economic sideboards and regulatory constraints impacting private landowners. These pilot programs are applicable to a range of landowners (owners of both large and small parcels), and a diversity of land management and land use interests from high intensity agriculture and development to low intensity grazing and forestry.
The mountain parks of the North Coast and Cascades Network (NCCN) span a gradient of urban influence, and a west-east precipitation gradient. Because of these gradients, network parks and areas within may respond differently to certain stressors (e.g., atmospheric deposition of contaminants), while responding similarly to others (e.g., global climate change). This collaborative project with Central Washington University (CWU) involves continuation of long-term monitoring of precipitation chemistry in Mount Rainier National Park (MORA)), and the analysis of surface water samples, to better understand the relationship between natural processes and perturbations. By sampling on a continuous basis with consistent techniques,...

This project generated a series of freely available datasets that provide projections of climate change at appropriate spatial scales that can directly address specific management questions. These climate change projections are the result of “downscaling” output from global climate models (GCMs) that formed the basis of many conclusions in the Intergovernmental Panel on Climate Change (IPCC) Assessment Report 5 (AR5). The datasets include projections of climate variables in addition to daily temperature and precipitation such as surface winds, humidity, and solar radiation that are needed in hydrologic and ecological modeling. Two products, one at a 4-km resolution and the other at a 6-km resolution, covering the...

When climate models are developed, researchers test how well they replicate the climate system by using them to model past climate. Ideally, the model output will match the climate conditions that were actually recorded in the past, indicating that the model correctly characterizes how the climate system works and can be used to reliably project future conditions. However, this approach assumes that models that reliably project past climate conditions will accurately predict future climate conditions, even though the climate system might have changed. This research contributes to generating more reliable local-scale climate projections by testing the assumption that the climatological relationships which existed...

The Colorado River is the dominant water source for the southwestern United States, crossing through seven states before reaching Mexico. The river supplies water to approximately 36 million people, irrigates nearly six million acres of farmland within and beyond the basin, and contributes an estimated 26 billion dollars each year to the region’s recreational economy. Yet the Colorado River’s water supply is already fully allocated, meaning that the economic and environmental health of the region is closely tied to the river’s streamflow. Climate projections for the Southwest show a future marked by chronic drought and substantial reductions in streamflow. The region has already been impacted by climate change,...

Coral reefs provide numerous ecosystem goods and services critical to human well-being (e.g., protection from storms and floods, food, income, recreation, and cultural practices), but they are threatened by growing human pressures and climate change. Resource managers must make complex decisions when developing adaptation plans that are cost-effective and maintain coral reef functions while still allowing for human use and development. Through this project, scientists developed a decision-support tool for managers to (1) identify the areas that provide the most critical coral reef services (i.e., supply the most value to humans) as well as the areas of reef most threatened, and (2) compare the effects of reef management...

For thousands of years, Pacific lamprey and Pacific eulachon have been important traditional foods for Native American tribes of the Columbia River Basin and coastal areas of Oregon and Washington. These fish have large ranges – spending part of their lives in the ocean and part in freshwater streams – and they require specific environmental conditions to survive, migrate, and reproduce. For these reasons, Pacific lamprey and Pacific eulachon are likely threatened by a variety of climate change impacts to both their ocean and freshwater habitats. However, to date, little research has explored these impacts, despite the importance of these species to tribal communities. This project will evaluate the effects of...

This project links climate, hydrological, and ecological changes over the next 30 years in a Great Basin watershed. In recent years, climate variability on annual and decadal time scales has been recognized as greater than commonly perceived with increasing impacts on ecosystems and available water resources. Changes in vegetation distribution, composition and productivity resulting from climate change affect plant water use, which in turn can alter stream flow, groundwater and eventually available water resources. To better understand these links, project researchers implemented two computer-based numeric models in the Cleve Creek watershed in the Schell Creek Range, east of Ely, Nevada. The application of the...

Species that inhabit the arid Southwest are adapted to living in hot, dry environments. Yet the increasing frequency and severity of drought in the region may create conditions that even these hardy species can’t survive. This project examined the impacts of drought in the southwestern U.S. on four of the region’s iconic species: desert bighorn sheep, American pronghorn, scaled quail, and Rio Grande cutthroat trout. Grasping the impacts of drought on fish and wildlife is critical for management planning in the Southwest, as climate models project warmer, drier conditions for the region in the future. Species are known to respond to environmental changes such as drought in different ways. Often, before changes...

This project will assess the accuracy of climate drivers (precipitation and temperature) from different sources for current and future conditions. The impact of these drivers on hydrologic response will be using the monthly water balance model (MWBM). The methodology for processing and analysis of these datasets will be automated for when new climate datasets become available on the USGS Geo Data Portal ( http://cida.usgs.gov/climate/gdp/). This will ensure continued relevancy of project results, future opportunities for research and assessment of potential climate change impacts on hydrologic resources, and comparison between generations of climate data. To share and distribute the results with scientists and...

How can the public discover opportunities for participation in USGS scientific research? What citizen science projects are currently active within the USGS? How may PIs increase public engagement in and awareness of their citizen science projects? To address these questions, a web application leveraging existing Community for Data Integration (CDI) and USGS work was created to allow unprecedented public access to USGS citizen science project metadata and highlights of key science outcomes. Such an application enables, for the first time, high-visibility, unified open access to information about projects and practices related to citizen participation in USGS research. The need for such information was identified...
A number of monitoring method and protocol libraries are currently in existence. Although these systems have been tailored to certain disciplines or research foci, the underlying principles, mechanisms, and processes have commonalities that could facilitate synthesizing content and information. The Protocol Library project consists of modifying and thus extending the capabilities of the existing NEMI methods compendium. To accomplish the task of incorporating a broad array of protocols, NEMI developers have conducted user requirement queries of protocol owners. In addition, protocol owners have been asked how they would prefer to access the data. Input forms have been created to accommodate the desires of protocol...

The Prairie Pothole Region spans parts of North and South Dakota, Minnesota, Montana, Iowa and south-central Canada and contains millions of wetlands that provide habitat for breeding and migrating birds. Because it is the continent’s most important breeding area for waterfowl, conservation and management largely focuses on protecting habitat for nesting ducks. However, other wetland-dependent birds also rely on this region, and it is important to understand the degree to which habitat conserved for ducks provides habitat for other species, and how the quality of this habitat will be affected by climate change. Project researchers tested whether waterfowl are effective representatives, or surrogates, for other wetland-dependent...

The Bird Conservancy of the Rockies will use, combine and optimize an array of remote sensing techniques to identify the most efficient process that characterizes grasslands and level of shrub component in those grasslands. The project will classify a pilot area, the Janos Grassland Priority Conservation Area, which contains the majority of the Janos Biosphere Reserve, using a variety of remote sensing approaches. In the process they will identify the best techniques for decomposing grass-shrub intermix at low densities and identify the best approaches for large scale application of remote sensing to classify the desert grasslands and shrublands.
