The influence of recent climate change on the world’s biota has manifested broadly, resulting in latitudinal range shifts, advancing dates of arrival of migrants and onset of breeding, and altered community relationships. Climate change elevates conservation concerns worldwide because it will likely exacerbate a broad range of identified threats to animal populations. In the past few decades, grassland birds have declined faster than other North American avifauna, largely due to habitat threats such as the intensification of agriculture. We examine the effects of local climatic variations on the breeding performance of a bird endemic to the shortgrass prairie, the Lark Bunting (Calamospiza melanocorys) and discuss...

Playa wetlands on the west-central Great Plains of North America are vulnerable to sediment infilling from upland agriculture, putting at risk several important ecosystem services as well as essential habitats and food resources of diverse wetland-dependent biota. Climate predictions for this semi-arid area indicate reduced precipitation which may alter rates of erosion, runoff, and sedimentation of playas. We forecasted erosion rates, sediment depths, and resultant playa wetland depths across the west-central Great Plains and examined the relative roles of land use context and projected changes in precipitation in the sedimentation process. We estimated erosion with the Revised Universal Soil Loss Equation (RUSLE)...

Article Abstract: Although riparian and aquatic ecosystems make up a small fraction of the area in arid and semi-arid lands, they are critical for the survival of desert life. There are, however, few compendia of efforts to define the quantity of water needed to maintain these ecosystems and understand the risks and stressors to them. Through our analysis we found that 62% of the rivers examined in the deserts of the U.S. and Mexico have had just one study over the past four decades and 67% of studies used qualitative methods. Furthermore, only one-third of the 312 species catalogued in our work have been studied more than once and only 5% have been considered five or more times. The most common risks or stressors...

This dataset was developed by the Crown Managers Partnership, as part of a transboundary collaborative management initiative for the Crown of the Continent Ecosystem, based on commonly identified management priorities that are relevant at the landscape scale. The CMP is collaborative group of land managers, scientists, and stakeholder in the CCE. For more information on the CMP and its collaborators, programs, and projects please visit: http://crownmanagers.org/This geodatabase contains all freely available spatial information on trails accessible by All-Terrain-Vehicles (ATV’s) as well as utility and logging cutlines in the Crown of the Continent area. Due to the free nature of the data, it is of mixed quality...

Active coal mine operations in the East Kootenay region of SE British Columbia. This dataset was compiled from Teck Resources and ESRI google Earth 2013 imagery. This dataset was developed as part of the Crown Managers Partnership on going effort to develop seamless transboundary datasets across the Crown of the Continent Ecosystem.

Our primary goal for this dataset was to obtain the population and number of dwellings at the finest common scale possible. Because the Canadian government first began to collect the pertinent census information at our desired scale in 2006, we used 2006 as the baseline for this product on the Canadian CCE. However, because (1) U.S. Census takes place every 10 years, and (2) our desired baseline date for the protocol was 2000, the census 2000 blocks were used on the U.S. CCE. This dataset was developed by the Crown Managers Partnership, as part of a transboundary collaborative management initiative for the Crown of the Continent Ecosystem, based on commonly identified management priorities that are relevant at the...

British Columbia, Alberta and Montana land ownership data.This polygon dataset represents an up-to-date picture of land management and ownership across the crown of the continent ecosystem. This dataset represents the federal, provincial/state, and local government agencies responsible for managing land. This dataset also shows the private land, private conservation lands, and land held by Plum Creek Timber.The Alberta Data was acquired from AltaLIS for parks and protected area data, and Alberta Sustainable Resource Development for the remaining public and private lands. The Reservations in Alberta were derived from a map created by the Miistakis institute. The BC data was provided by the BC Ministry of Forests,...

This layer respresents First Nations Reservations that occupy area in the Crown of the Continent Ecosystem or occupy area within a 50 kilometer buffer surrounding the border. The data is derived from Alberta and British Columbia data from GeoGratis, which was created in 2003 and revised in 2015; and Montana data from the US Bureau of Land Management (BMSC).

This categorical CWD raster was developed from a project-wide CWD raster. For each of the five fracture zones, the CWD raster was partitioned into zone-specific, 10 equal-area class map, ranging from low CWD to high CWD.

Ten focal species cost-weighted distance (CWD) surfaces from WHCWG (2010) were combined into a single categorical raster for this project. The source focal species were: western toad, northern flying squirrel, wolverine, Canada lynx, American marten, mountain goat, American black bear, elk, mule deer, and bighorn sheep.

This cost-weighted distance (CWD) raster was developed from a generalized shrub-steppe and grassland (SSGL) species guild resistance model based on 20th percentile of resistance values for the five statewide analysis (WHCWG 2010) focal species in this biome, including sage-grouse, black-tailed jackrabbit, white-tailed jackrabbit, badger, and sharp-tailed grouse.

Habitat similarity index (HSI) values for greater sage-grouse across their western range. HSI values represent the relationship of environmental values at map locations to the multivariate model of minimum requirements for sage-grouse dened by land cover, anthropogenic variables, soil, topography, and climate.

Understanding a species’ behavioral response to rapid environmental change is an ongoing challenge in modern conservation. Anthropogenic landscape modification, or “human footprint,” is well documented as a central cause of large mammal decline and range contractions where the proximal mechanisms of decline are often contentious. Direct mortality is an obvious cause; alternatively, human‐modified landscapes perceived as unsuitable by some species may contribute to shifts in space use through preferential habitat selection. A useful approach to tease these effects apart is to determine whether behaviors potentially associated with risk vary with human footprint. We hypothesized wolverine (Gulo gulo) behaviors vary...
