The Yukon North Slope is an arctic “hot spot” of climate change-induced effects with profound significance for the Inuvialuit and the larger region. In 1984, the Inuvialuit entered into a land claim agreement – the Inuvialuit Final Agreement (IFA) – with the governments of Canada, Yukon and Northwest Territories. A co-management body formed to make a plan, which was developed in 2003 but never ratified and is now considered out-of-date. Round River Conservation Studies is assisting WMAC(NS) in the collection, development and synthesis of spatial data, models and analyses of cultural and ecological values of the YNS.The project is a collaboration among the NWB LCC, Round River Conservation Studies, and the Arctic...

Climate change vulnerability assessments are commonly used to identify species or populations at risk from global climate change, but few translate impact assessments to climate change adaptation actions. Furthermore, most climate change adaptation efforts emphasize where to implement management actions, whereas timing remains largely overlooked. The rate of modern climate change introduces urgency in evaluating whether delaying conservation actions compromises their efficacy for reaching important conservation targets. We evaluated the importance of multiple climate change adaptation strategies including timing of actions on preventing extinctions for a threatened climate-sensitive species, the Eastern Massasauga...

We used publically available data on duck breeding distribution and recently compiled geospatialdata on upland habitat and environmental conditions to develop a spatially explicitmodel of breeding duck populations across the entire Prairie Pothole Region (PPR). Ourspatial population models were able to identify key areas for duck conservation across thePPR and predict between 62.1 – 79.1% (68.4% avg.) of the variation in duck counts by yearfrom 2002 – 2010. The median difference in observed vs. predicted duck counts at a transectsegment level was 4.6 ducks. Our models are the first seamless spatially explicit modelsof waterfowl abundance across the entire PPR and represent an initial step toward jointconservation...

In practice, there are a number of challenges associated with formal consideration of the environment in water planning in large parts of the Desert LCC region. In Arizona, for example, there is no legal requirement to include the environment in water management or planning efforts (Megdal et al. 201 0). Therefore, there is little incentive to develop the additional tools and resources required to include the environment as a water demand sector. Appropriate inclusion of the environment into water planning requires conducting planning at a scale and geography that matches regional hydrology rather than political boundaries. Therefore, without explicit policy guidance from state government, regional stakeholders...

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...
Hawaiian forest birds are imperiled, with fewer than half the original >40 species remaining extant. Recent studies document ongoing rapid population decline and project complete climate‐based range losses for the critically endangered Kaua’i endemics ‘akeke’e (Loxops caeruleirostris) and ‘akikiki (Oreomystis bairdi) by end‐of‐century due to projected warming. Climate change facilitates the upward expansion of avian malaria into native high elevation forests where disease was historically absent. While intensified conservation efforts attempt to safeguard these species and their habitats, the magnitude of potential loss and the urgency of this situation require all conservation options to be seriously considered....

The potential ecological and economic effects of climate change for tropical islands were studied using output from 12 statistically downscaled general circulation models (GCMs) taking Puerto Rico as a test case. Two model selection/model averaging strategies were used: the average of all available GCMs and the average of the models that are able to reproduce the observed large-scale dynamics that control precipitation over the Caribbean. Five island-wide and multidecadal averages of daily precipitation and temperature wereestimated by way of a climatology-informed interpolation of the site-specific downscaled climate model output. Annual cooling degree-days (CDD) were calculated as a proxy index for air-conditioning...
AbstractContext Conservation planning is increasingly using ‘‘coarse filters’’ based on the idea of conserving ‘‘nature’s stage’’. One such approach is based on ecosystems and the concept of ecological integrity, although myriad ways exist to measure ecological integrity.Objectives To describe our ecosystem-based index of ecological integrity (IEI) and its derivative index of ecological impact (ecoImpact), and illustrate their applications for conservation assessment and planning in the northeastern United States.Methods We characterized the biophysical setting of the landscape at the 30 m cell resolution using a parsimonious suite of settings variables. Based on these settings variables and mapped ecosystems, we...
Open canopy conditions in southeastern pine (Pinus spp.) forests were historically maintained by frequent fire and other disturbances, without which midstory hardwoods create closed canopy conditions limiting value of pine stands for many endemic, disturbance-adapted species. Intensively managed pine forests, which comprise 19% of forests in the southeastern U.S., can emulate historical open pine conditions, providing appropriate vegetation structure and composition for many endemic species. However, exact mechanisms for producing and maintaining open pine conditions and subsequent effects on biodiversity have not been examined across regions and stand ages. To better inform managers about options for providing...

Governmental and nongovernmental organizations charged with managingnatural resources increasingly emphasize the need to work across jurisdictional boundaries.Their challenge is to manage shifting resources under rapidly changing climate andland-use scenarios. Scientists, resource managers, and conservation planners, and theirorganizations and agencies routinely collaborate on projects to solve specific problems.Cooperative frameworks to programmatically address complex social–environmental issuesand develop shared research, planning, and implementation priorities are relatively new.One such framework includes 22 Landscape Conservation Cooperatives that encompass the US, Caribbean countries, and bordering regions...

Throughout the Caribbean, conservation is ecologically, politically, and sociallychallenging due to a number of factors including globalization, climate change, loss ofbiodiversity, and the spread of invasive species. Relationships between organizations andinstitutions that govern the region’s natural and cultural resources are key to conservationsuccess as partners work to implement plans to meet science, capacity, and informationneeds. However, the complex challenges involved in conservation work and tenuous relationshipsamong organizations can result in a “knowing–doing gap”. Empirical evidencefrom 130 Caribbean conservation organizations indicates that barriers to bridging this gapare lack of information and...

This study quantitatively explores whether land cover changes have a substantive impact on simulated streamflow within the tropical island setting of Puerto Rico. The Precipitation Runoff Modeling System (PRMS) was used to compare streamflow simulations based on five static parameterizations of land cover with those based on dynamically varying parameters derived from four land cover scenes for the period 1953-2012. The PRMS simulations based on static land cover illustrated consistent differences in simulated streamflow across the island. It was determined that the scale of the analysis makes a difference: large regions with localized areas that have undergone dramatic land cover change may show negligible difference...

Executive summary: Tamarisk control and removal has become a priority of riparian ecosystem management, due in part to its potential negative impacts on stream flow and groundwater recharge. Among the most controversial, and potentially most effective tamarisk control approaches is the introduction of the tamarisk leaf beetle, Diorhabda carinulata. The beetle has spread throughout virtually the entire upper Colorado River Basin, established major populations at Lake Mead in 2012, and is now poised to expand into the lower Colorado River Basin concordant with documented evolutionary change in beetle developmental response that may enable survival in southern regions. Superimposed on this direct plant/herbivore relationship...

Dozens of species of landbirds, such as warblers, hummingbirds, and orioles, migrate through the Northeastern United States from their summer breeding grounds in the U.S. and Canada to their nonbreeding grounds as far south as South America. During the migration period, birds must find habitat where they can stop, rest and replenish their energy reserves. Conservation efforts are increasingly focused on identifying stopover sites that are important for sustaining migratory landbird populations. This project builds upon prior work by the University of Delaware and USGS to use weather surveillance data and field surveys to map and predict important migratory bird stopover sites.This project was co-funded by through...
