Montana Department of Fish, Wildlife and Parks (MTFWP) has been involved with developing a crucial areas statewide Decision Support System (DSS) since 2008 in parallel with activities from the Western Governors Association (WGA). In April, 2010, the Crucial Areas Planning System (CAPS) was released. Also in 2010, the WGA provided funding to the 18 western states to begin developing DSSs for crucial areas among and between the 18 western states. MTFWP will be piloting a transboundary DSS for fish, wildlife, and habitats along the Idaho-Montana Divide, beginning in July 2010. MTFWP will also participating in a dual role of advisory and collaboration with the Washington, Oregon and Idaho Columbia Plateau pilot project.This...

We propose an international partnership to facilitate the identification of habitat connectivity conservation opportunities and implementation of connectivity projects in the transboundary area of Washington and British Columbia. The project will engage a transboundary subgroup of the WHCWG co-led by experts from both Washington and British Columbia to: (1) summarize and interpret our statewide and Columbia Plateau ecoregional products (see www.waconnected.org), as well as provincial products, with the objective of highlighting general connectivity patterns and to define where and how to focus our operational-scale transboundary habitat connectivity analyses; (2) establish subregional teams to collaborate on finer-scale...

This project will focus on analysis of 10 years of GPS telemetry data for 60 grizzly bears across the threatened and fragmented trans-border grizzly bear subpopulations in the Cabinet, Yaak, Purcell, and Selkirk Mountain (Proctor et al. 2012) with a goal to identify areas of high quality core habitat and understand the ecological characteristics that underpin habitat use. We will use Resource Selection Function habitat-use models for partitioned by sex and in each of 3 seasons to capture the variation of bear habitat use. We will also work to integrate our results to inform wildlife and land managers on where to concentrate their management efforts by season to promote population health and resilience in both the...

Our goal was to predict road culvert passability, as defined by culvert outlet drop and outlet water velocity, for three fish swimming groups using remotely collected environmental variables that have been shown to influence the passability of road culverts.We generated four boosted regression tree models, one for road culvert outlet drop and one each for the three culvert outlet water velocities, and predicted the probability of impassable road culverts on low-order streams based on the models. Independent variables in the modelsincluded the upstream area draining to the culvert, slope at the culvert, stream segment gradient and stream reach gradient.Gradient of the stream segment was the most important predictor...

Northern Great Lakes forests represent an ecotone in the boreal–temperate transition zone and are expected to change dramatically with climate change. Managers are increasingly seeking adaptation strategies to manage these forests. We explored the efficacy of two alternative management scenarios compared with business-as-usual (BAU) management: expanding forest reserves meant to preserve forest identity and increase resistance, and modified silviculture meant to preserve forest function and increase adaptive capacity. Our study landscapes encompassed northeastern Minnesota and northern Lower Michigan, which are predicted to experience significant changes in a future climate and represent a gradient of latitude,...
Estimation of connectivity for multiple species could increase the efficiency of resource management and elucidate trade-offs among maintenance of connectivity for different taxa. We identified potential areas of high connectivity for 5 species of mammals on the Navajo Nation and adjacent lands in Utah, Arizona, and New Mexico, USA: mountain lion (Puma concolor), mule deer (Odocoileus hemionus), desert bighorn sheep (Ovis canadensis nelsoni), American black bear (Ursus americanus), and pronghorn (Antilocapra americana). These species were identified by the Navajo Nation as relevant to the benefit of their present and future generations. We used telemetry data to calculate utilization distributions, derive model...

Resilience concerns the ability of a living system to adjust to climate change, to moderate potential damages, to take advantage of opportunities, or to cope with consequences; in short, its capacity to adapt. In this project we aim to identify the most resilient examples of key geophysical settings (e.g. sand plains, granite mountains, limestone valleys, etc.) in New york State to provide conservationists with a nuanced picture of the places where conservation is most likely to succeed over centuries.The project had three parts: 1) identifying and mapping the geophysical settings, 2) developing a quantitative estimate of resilience for each setting based on landscape complexity and permeability, and 3) identifying...

These data represent a potential Conservation Target (CT) of PFLCC's Priority Resource (PR) "Connectivity." This layer shows the overlap of PFLCC's Connectivity Priority Resource (PR) with Florida's Priority Ecological Areas (PEAs), representing the quality of hubs in the PR. The number and configuration of hubs is a potential conservation target for this PR. PEAs are areas of statewide ecological significance that are based on established GIS data for identifying areas important for conserving biodiversity and ecosystem services. PEAs are the base building block of the Florida Ecological Greenways Network that are used to help identify large, intact, and potentially functionally connected natural and semi-natural...
This broad-scale landscape connectivity dataset identifies areas likely to facilitate ecological flow—particularly movement, dispersal, gene flow, and distributional range shifts for terrestrial plants and animals—over large distances and long time periods. Similar to the local permeability analyses (3km radius, Buttrick et al. 2015), this analysis is not species-specific. Rather, it focuses on structural connectivity of natural lands, with resistance to movement modeled as a function of landscape naturalness. This map does not incorporate projections of future climates, nor does it address connectivity for aquatic species. The results identify broad, intact areas where movement of terrestrial organisms is largely...

Biologists, engineers, planners and land managers from nine public agencies have worked together since 2004 to identify large blocks of protected habitat, the potential wildlife movement corridors through and between them, the factors that could possibly disrupt these linkage zones and opportunities for conservation. Recognizing that habitat connectivity is a landscape issue involving multiple land jurisdictions, this workgroup has engaged in unprecedented cooperation and facilitated discussions and partnerships to help ensure a unified approach to wildlife linkage conservation and management. This reinforces the commitment to and efficiency of wildlife connectivity measures undertaken by all stakeholders, using...

When the Earth experiences changes in its climate, wildlife respond by moving – species adjust their ranges to track changes in climate, moving out of areas that become too hot or otherwise inhospitable, and moving into areas that become newly hospitable. However, climate change is now proceeding so quickly that it is becoming difficult for species to move fast enough to keep pace. In addition, today’s landscapes feature significant barriers to movement presented by human land uses (e.g., roads, cities, farms). Such is the case in the region around the border of Washington and British Columbia, where increasing development pressure and limited coordination of land and wildlife management across the border pose a...

Conclusions: Although there was not a detectable decrease in bird communitiy species richness resulting from experimental forest fragmentation, community structure was altered, and maintaining connections between fragments significantly mitigated these effects. Thresholds/Learnings: Synopsis: This study examined the effects of forest fragmentation on the richness, diversity, turnover, and abundance of breeding bird communities in old boreal mixed-wood forest by creating experimental forest fragments of 1, 10, 40, and 100 ha. Connected fragments were linked by 100 m wide buffer strips. The study detected no significant change in species richness as a result of forest harvesting, except in the 1 ha connected fragments...
