The Nature Conservancy - Great Lakes Program is leading the development of a scalable (Great Lakes wide, individual lake basin, to coastal reach within a lake basin) rule-based spatial model for ranking the relative importance of coastal lands and waters as habitat for migrating birds. Results will guide conservation actions including land acquisition, land and water management and restoration, and development of wind energy facilities. Specifically, the team will: 1) refine, create and integrate migratory bird stopover habitat models which depict the distribution of potential stopover sites along or near the shorelines of Lakes Michigan, Huron, Erie, and Ontario; and, 2) develop an online portal that will deliver...

Sediment accumulation threatens the viability and hydrologic functioning of many naturally formed depressional wetlands across the interior regions of North America. These wetlands provide many ecosystem services and vital habitats for diverse plant and animal communities. Climate change may further impact sediment accumulation rates in the context of current land use patterns. We estimated sediment accretion in wetlands within a region renowned for its large populations of breeding waterfowl and migrant shorebirds and examined the relative roles of precipitation and land use context in the sedimentation process. We modeled rates of sediment accumulation from 1971 through 2100 using the Revised Universal Soil Loss...

These data were developed to support an effort to characterize migration strategies in the U.S. Great Plains and Canadian Prairies and to explore sources of heterogeneity in their migration strategy, including space use, timing, and performance. Data come from locations and other information related to 58 marked Whooping Cranes (Grus americana) from 2010–2016. These data represent basic information about migrations of marked whooping cranes, including dates of initiation and termination of migration, time in migration, distance of migration, number of stopover sites used, and other metrics. Also included are data related to individual sites used by whooping cranes during migration.

The whooping crane (Grus americana) is a bird species in North America currently protected under federal endangered species legislation in the United States and Canada. The only self-sustaining and wild population of whooping cranes nests in and around Wood Buffalo National Park near the provincial border of Northwest Territories and Alberta, Canada. Cranes from this population migrate through the Great Plains of North America and winter along the Gulf Coast of Texas at Aransas National Wildlife Refuge and surrounding lands. These data support efforts to delineate a migration corridor for this population that can be used for conservation planning activities, including targeting conservation, mitigation, and recovery...

Rehabilitation of about 7 miles of dike for the B-Q Canal; creating a grass bank at Cokeville Meadows NWR; planting and weed control will restore 1,300 acres of irrigated hay meadows on the Refuge that are currently unproductive; monitoring elk movement east of NWR. This project will improve irrigation efficiency and flooding of approximately 1,300 acres of hay meadows that are currently unproductive. These improvements will increase nesting habitat for the...
Playas and other wetlands within the Great Plains Landscape Conservation Cooperative (GPLCC) provide essential habitat for many wetland-dependent vertebrate species and are especially important as migration and wintering areas for waterfowl and shorebirds. Playas in the GPLCC are at risk of unsustainable sediment accumulation, reduced inundation frequency, and declining hydroperiods due to agricultural intensification and a changing climate with expected decreases in annual precipitation, changing precipitation patterns, and higher summer temperatures. We propose to project distribution shifts and/or range reductions of several focal migrating shorebird, waterfowl, and waterbird species in response to climate change,...

Full life-cycle vulnerability assessments are identifying the effects of climate change on nongame migratory birds that are of conservation concern and breed in the upper Midwest and Great Lakes region. Full life-cycle analyses are critical, as current efforts likely underestimate the vulnerability of migratory land birds due to a focus on assessing only one component of the annual cycle. The approach provides a framework for integrating exposure to climate changes, sensitivity to these changes, and the potential for adaptation in both winter and summer seasons, and accounts for carry-over effects from one season to another. The results of this work will inform regional management by highlighting both local and...

Advancement in Geographical Information System (GIS) data development, management, and analysis has allowed conservation practitioners to apply ecological theory into conservation delivery at broad landscape scales. This project demonstrated that process with the creation of Decision Support Tools (DST) to guide on-the-ground habitat delivery to those areas on the landscape that, if managed, will provide the greatest biological return for the conservation dollar invested. This project focused on the habitat needs of Sandhill cranes and waterfowl, as a guild, during spring migration. Understanding the species habitat relationships for these priority species/guild will allow the conservation community to more effectively...

Data files in this data series represent migrating bird count and habitat information collected during 1989, 1991, 1993, and 1994 field seasons at 13 riparian sites along the San Pedro River and its tributaries in southeastern Arizona, USA. At each site observations were made at up to 20 points, separated by 100 m arrayed along the riparian zone. Observation periods started at 20 minutes after sunrise, lasted for 7 minutes at each point and were completed within 4 hours. Bird detection and species identification were based on visual sighting, song, and call. Recorded observations were the number of individuals of each detected species detected using each detection method at each point and site within specified distance...

Climate change poses major challenges for conservation and management because it alters the area, quality, and spatial distribution of habitat for natural populations. To assess species’ vulnerability to climate change and target ongoing conservation investments, researchers and managers often consider the effects of projected changes in climate and land use on future habitat availability and quality and the uncertainty associated with these projections. Here, we draw on tools from hydrology and climate science to project the impact of climate change on the density of wetlands in the Prairie Pothole Region of the USA, a critical area for breeding waterfowl and other wetland-dependent species. We evaluate the potential...

Wind power is a promising clean energy technology that has grown rapidly in recent years (EIA 2013). In spite of its environmentally friendly reputation, industrial wind energy generation can have serious impacts on wildlife. Bat and bird collision fatality rates have been alarmingly high at some wind farms. Proper siting of wind facilities may help minimize collision impacts as the wind energy industry continues to grow. Bat and bird fatality rates vary greatly among sites; however, there is no reliable method for assessing collision risk prior to development. My goal was to develop a method for predicting fatality rates based on nocturnal activity patterns measured by ground-level recording of bat and bird calls....

Migratory birds are important for recreation and tourism, contributing to a vibrant birdwatching industry in Alaska. Every spring, hundreds of birds migrate to their summer breeding grounds in Alaska and northern Canada. Their arrival is timed with the height of the spring green-up of plants, which provide the food necessary for birds to reproduce and raise their young. However, over the last fifty years, warming temperatures in Alaska as a result of climate change have prompted an earlier transition from winter to spring. The purpose of this project was to examine whether there have been changes in the timing of spring green-up in recent years (1985-2009) and, if so, whether migratory birds are adapting their migration...

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...

Migratory birds are responding to changes in climate in complex and sometimes unpredictable ways. The timing of breeding and migration typically coincide with the periods of peak food availability; however, these peaks are shifting as temperatures and precipitation patterns change, resulting in a mismatch in the timing of key events. The degree to which this mismatch is impacting migratory birds varies among species and regions, creating a major source of uncertainty for managers. The goal of this project is to develop tools to support migratory bird management decision-making in the face of uncertain future climate and land use conditions. In order to identify and implement the most effective management strategies,...
