This dataset contains thespecies richness (total number of CEs) value for each 5th level HUC was calculated using the fine-filter. CE richness for the terrestrial EI was calculated by summing the number of fine-filter terrestrial CEs occurring in each HUC based on the distribution outputs used for the fine-filter CE analysis. These species included the grizzly bear, greater sage-grouse (GRSG), golden eagle, mule deer, elk, bighorn sheep, Canada lynx, American marten, and the wolverine CEs in the Middle Rockies ecoregion.

We investigated the dynamics of canine distemper virus (CDV) in grizzly bears (Ursus arctos) and wolves (Canis lupus) of the Greater Yellowstone Ecosystem (GYE) using serological data collected from 1984 to 2014. 565 sera samples were obtained from 425 unique grizzly bears (134 females and 291 males) from 1984 to 2014 and 319 sera samples were obtained from 285 unique wolves (130 females and 155 males) from 1996 to 2014. Here we provide the unique identifier for each individual, the species and sex, the date the individual was captured, the estimated birth year and age, and the CDV antibody titer results based upon serum neutralization assays.

The Randomized Shortest Path (RSP) raster delineates potential dispersal paths for male-mediated gene flow between grizzly bear (Ursus arctos) populations in the Greater Yellowstone Ecosystem (GYE) and the Northern Continental Divide Ecosystem (NCDE). A RSP algorithm was used to estimate the average number of net passages for all grid cells at a spatial resolution of 300 m in the study region which spans parts of Montana, Idaho, and Wyoming. RSP rasters identify potential movement paths for 3 levels of random deviation determined by the parameter Θ (i.e., Θ = 0.01, 0.001, and 0.0001) for bears moving from an origin to a destination node. Lower values of Θ result in greater exploration and more random deviation around...

In May 2014, the GNLCC Steering Committee approved two pilot projects explore approaches to landscape-scale coordination to enhance science-based management across the GNLCC. The two ‘Shared Landscape Outcomes’ pilots were designed to assess and focus on specific pairs of a GNLCC Goal and a priority landscape stressor (as defined in the Strategic Conservation Framework) and focus the approach at the entire GNLCC scale. The two pilot projects focused on (1) the Connectivity goal and Land Use Change stressor (described here) and (2) the Aquatic Integrity goal and Invasives stressor and (see: http://greatnorthernlcc.org/PTS/prj_report.html?PRJ_ID=403 )Connectivity Pilot:Wildlife species are becoming increasingly isolated...

Digital coverage created by buffering all motorized routes (open roads, restricted roads, railroads, and motorized trails) by 500m and clipping to the Grizzly Bear Management Unit (BMU) boundaries.
The Madison Valley is an important wildlife linkage zone between core habitats at the center of the Greater Yellowstone Ecosystem (GYE) and habitats at the western edge of the GYE and beyond. This report identifies lands in the Madison Valley watershed which are significant for conservation based on the common occurrence of key threats to wildlife and their critical habitats and migration corridors. The species emphasized in this report - grizzly bear, wolverine, and pronghorn antelope - were selected for their need to move across or along the valley to maintain traditional migration routes, enable genetic exchange across the valley, or expand into unoccupied habitat. The selected species are also intended to serve...

Landscape simulation modeling will be used to develop detailed management guidelines for restoring and sustaining whitebark pine under future climates, accounting for the principal stressors that threaten its persistence (exotic disease infections, mountain pine beetles, and fire exclusion policies). We will build on existing work, including the 2012 publication A Range-Wide Restoration Strategy for Whitebark Pine Forests and existing simulation areas within critical whitebark pine habitat. This project will create a robust and trans-boundary set of management tools for creating resistant and resilient whitebark pine forests within the Rocky Mountains, USA and Canada.FY2013Objectives:We propose to use FireBGCv2...

Establishing connections among natural landscapes is the most frequently recommended strategy for adapting management of natural resources in response to climate change. The U.S. Northern Rockies still support a full suite of native wildlife, and survival of these populations depends on connected landscapes. Connected landscapes support current migration and dispersal as well as future shifts in species ranges that will be necessary for species to adapt to our changing climate. Working in partnership with state and federal resource managers and private land trusts, we sought to: 1) understand how future climate change may alter habitat composition of landscapes expected to serve as important connections for wildlife,...

The Grizzly Bear Recovery Zone (GBRZ) for the Greater Yellowstone Ecosystem (GYE) delineates the area inside the GYE where demographic and habitat criteria were applied, monitored, and evaluated to achieve recovered status of the Yellowstone grizzly bear population. The GBRZ was established by the U.S. Fish and Wildlife Service (USFWS) in 1993 as part of the Recovery Plan for grizzly bears in the lower 48 conterminous United States. The recovery zone boundary identifies the known distribution of bears at that time and encompasses seasonal habitats needed to support a recovered population. The GYE recovery zone spans portions of Montana, Idaho and Wyoming and includes parts of 5 National Forests (Beaverhead-Deerlodge,...
The grizzly bear distribution boundary represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2004-2018. The distribution boundary was delineated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation. The boundary was delineated by the Interagency Grizzly Bear Study Team (IGBST) using an interpolation method based on grizzly bear telemetry and GPS locations as well as verified observations and signs of grizzly bears inside the Greater Yellowstone Ecosystem during 2004 to 2018.

We evaluate mortalities for population segments within the DMA by deriving estimates of total mortality for independent-age (≥2 years old) females and independent-age males, including estimates of unknown/unreported mortalities based on Cherry et al. (2002). We then determine the total annual mortality rate for these segments as a percent of their respective population estimates. For dependent-age bears (<2 years old), we determine the percent of human-caused mortality relative to size of the population segment but do not include estimates of unknown/unreported mortality. Mortality data in this data release represent the individual records documented by the Interagency Grizzly Bear Study Team on an annual basis....

This project aims to provide large landscape practitioners of the U.S. Northern Rockies with a decision support tool for prioritizing conservation action to mitigate road impacts on wildlife corridors. We will overlay analyses of corridor network centrality with analyses of wildlife-vehicle collision risk to identify where high-importance corridors meet high-impact road segments. Our findings will establish a rigorous, transparent basis for focusing road mitigation efforts where they will yield the greatest benefits to region-wide connectivity, and will be conveyed in the form of web-based map tools, a comprehensive written report, and a workshop for large landscape practitioners.Objectives:The primary objective...

The Conservation Strategy Management Area (CSMA) is an area within which a delisted Yellowstone grizzly bear population was managed with the objective to maintain a stable to increasing population. The CSMA was formalized in the 2007 Federal Rule (72 FR 14866) which removed the Yellowstone distinct population segment from Federal protection as a threatened species under the Endangered Species Act. The CSMA was delineated as the area from within which the Yellowstone grizzly bear population size was estimated and sustainable mortality thresholds and demographic criteria were applied. The decision to replace the CSMA boundary with the Demographic Monitoring Area was first approved by the Yellowstone Ecosystem Subcommittee...
For several decades, grizzly bear (Ursus arctos) populations in the Greater Yellowstone Ecosystem (GYE) and the Northern Continental Divide Ecosystem (NCDE) have increased in numbers and range extent. Whereas the NCDE population is contiguous with grizzly bear populations in the Canadian Rocky Mountains, genetic evidence suggests the GYE population remains isolated. Recent analyses indicate the effective population size of GYE grizzly bears has increased and is approaching levels needed for long-term viability. With only ~110 km distance separating current estimates of occupied range for these populations, the potential for immigration into the GYE from an NCDE migrant, or vice versa, is likely greater now than...
The Heart of the Rockies Initiative (HOTR), on behalf of its High Divide Collaborative partners, seeks support to identify and evaluate future landscape configurations that address the needs of local communities while conserving the High Divides unique landscape resources. In this landscape we emphasize wildlife connectivity between large protected core areas: Yellowstone, the Crown, and central Idaho (See attached map). This project builds on our prior GNLCC-funded project to deliver the latest science in connectivity and climate response and earlier stakeholder identification of lands of high conservation value (HOTR 2010). This project takes the next step by coupling socio-economic data and trends with conservation...
