Abstract: As the climate changes, human land use may impede species from tracking areas with suitable climates. Maintaining connectivity between areas of different temperatures could allow organisms to move along temperature gradients and allow species to continue to occupy the same temperature space as the climate warms. We used a coarse-filter approach to identify broad corridors for movement between areas where human influence is low while simultaneously routing the corridors along present-day spatial gradients of temperature. We modified a cost–distance algorithm to model these corridors and tested the model with data on current land-use and climate patterns in the Pacific Northwest of the United States. The...

The Aquatic Core Networks, Unstratified is comprised of unstratified versions of Lotic Core Areas and Lentic Core Areas. These datasets are one of two versions of aquatic core areas that are part of a suite of products from Nature’s Network (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. Although the stratified version “Aquatic Core Networks” is considered by the planning team to be the primary version for users, this unstratified version is also made available for reference and use.These and other datasets that augment or complement the Aquatic...

Freshwater Resilience, Highest and High, Watersheds for Complex and Non-complex Stream Networks, Northeast U.S. is one of a suite of products from the Nature’s Network project (naturesnetwork.org).As growing human populations increase the pace of climate and land use changes, estimating the resilience of freshwater systems will be increasingly important for delivering effective long-term conservation. A region-wide analysis of freshwater stream networks was developed by Mark Anderson and associates at The Nature Conservancy (Anderson et al., 2013) to estimate the capacity of each network to cope with climatic and environmental change. The analysis centered on the evaluation resiliency: characteristics that may...

Contributing to a core component of the Nature’s Network, the Western Pennsylvania Conservancy conducted an analysis on species-habitat associations data to develop a measure of overall species importance, summarized across all species, for each habitat class in the Northeast. This project extended the Habitat Associations project, in which the North Atlantic Landscape Conservation Cooperative partnered with NatureServe to produce a tabular dataset linking set of terrestrial and aquatic habitat layers with NatureServe element occurrence data for over 600 species of greatest conservation concern identified by states in FWS Region 5. Results data from the analysis were delivered in tabular format and joined to the...

Concerns about the influence of climate change on biota have emerged over the past decade, and responses in species populations and distribution patterns have already been documented (Parmesan 1996, Thomas and Lennon 1999). Current climates and communities will not simply migrate, but rather will re-form in novel ways over time (Fox 2007; Hunter et al. 1988; Williams and Jackson 2007). Due to the uncertainty of future climatic patterns and species responses, enduring features of the landscape (geophysical settings) are appropriate targets of assessment, planning, and conservation (Anderson and Ferree 2010, Beier and Brost 2010, Brost and Beier 2012; Hunter et al. 1988). Only recently have enduring features been...
We will develop SMART-SLEUTH, an advanced spatially explicit modeling framework designed to augment the current SLEUTH model with sophisticated smart-growth capabilities. Based on the latest version of SLEUTH, we will create an open-source GIS-enabled software package that will implement SMART-SLEUTH with advanced modules and tools for evaluating, predicting, and visualizing smart growth scenarios and outcomes. In this software package, a more user friendly Graphic User Interface (GUI), a multi-level automatic calibration approach built on machine learning algorithms, and new spatial landscape metrics for quantifying land change patterns will provide enhanced support for complex model configuration, calibration,...
The Nature Conservancy (TNC) recently completed an unprecedented assessment of almost 14,000 dams in the Northeastern United States. The Northeast Aquatic Connectivity (NAC) project allows fisheries managers and other interested parties to assess dams at multiple scales based on their potential to benefit anadromous and resident fish species if removed or bypassed. This work has continued, with support from NOAA and USFWS, in the Chesapeake Bay watershed, where data refinements and further analysis have produced a web map and tool that allow users to interactively prioritize dams for mitigation at multiple scales and with varying criteria.The Southeast Aquatic Resources Partnership (SARP) has recently completed...

A website with links to the Landscape Conservation Cooperative (LCC) Integrated Data Management Network (IDMN) final report as well as individual LCC websites. The IDMN worked with over 20 organizations over two years to bring coherence to the LCC information management landscape. Specifically, the IDMN Network tried to address ways LCC partners implemented the basic building blocks of data management. Issues addressed included building and sharing science products with partners, securely storing those data for the long term, and evaluating ways to get those outputs to cooperators and eventually the public. Over the course of the IDMN project, the scope was expanded to address ways to track projects that produced...

This dataset was last updated 02/2017. This version includes a new tidal restrictions metric that assesses the effect of undersized culverts and bridges on tidal regime.The previous version (3.1) was updated on 05/2016 by incorporating a revised version of the land cover classification, DSLland Version 3.1, developed by UMass, which included the addition of The Nature Conservancy’s Northeast lakes and ponds classification.This dataset depicts the ecological integrity of locations (represented by 30 m grid cells) throughout the northeastern United States based on environmental conditions existing in approximately 2010. Ecological integrity is defined as the ability of an area (e.g., local site or landscape) to sustain...

This dataset represents a species distribution model for least tern (Sternula antillarum) on New Jersey’s Atlantic coast and was created as part of the Protection of Critical Beach Habitat project. In addition to least tern, this project includes species distribution models for piping plover (Charadrius melodus), least tern (Sternula antillarum), and American oystercatcher (Haematopus palliatus). All species models can be found in the Data Basin gallery Protection of Critical Beach-nesting Bird Habitats in the Wake of Severe Coastal Storms.Species distribution modeling was conducted to examine the influence of landscape scale variables and beach management strategies on bird breeding habitat suitability. The probability...
We will develop an approach to identify fire refugia in Rocky Mountain ecosystems of the U.S. and Canada then test the function of refugia for biodiversity conservation under current and future climate/fire scenarios. Our products will be designed to inform decision-making in land/easement acquisition, identification of critical areas for maintaining landscape and process connectivity/permeability, and extension of the temporal context for spatial conservation decision making. The approach will be testable for transferability to other locations and ecosystems.

Population fragmentation compromises population viability, reduces a species ability to respond toclimate change, and ultimately may reduce biodiversi ty. We studied the current state and potential causes offragmentation in grizzly bears over approximat ely 1,000,000 km of western Canada, the northern United States(US), and southeast Alaska. We compiled much of our data from projects undertaken with a variety of researchobjectives including population estimation and trend, landscape fragmentation, habitat selection, vital rates, andresponse to human development. Our prim ary analytical techniques stemmed from genetic analysis of 3,134 bears,supplemented with radiotelemetry data from 792 bears. We used 15 locus microsatellite...

Much remains unknown about the genetic status and population connectivity of high-elevation and high-latitude freshwater invertebrates, which often persist near snow and ice masses that are disappearing due to climate change. Here we report on the conservation genetics of the meltwater stonefly Lednia tumana (Ricker) of Montana, USA, a cold-water obligate species. We sequenced 1530 bp of mtDNA from 116 L. tumana individuals representing “historic” (>10 yr old) and 2010 populations. The dominant haplotype was common in both time periods, while the second-most-common haplotype was found only in historic samples, having been lost in the interim. The 2010 populations also showed reduced gene and nucleotide diversity...

Climate change impacts many species through shifts in habitat. The intensity of this impact will depend on the dispersal rates of the species, the patchiness of the environment, and the velocity of habitat change. Here we examine how dispersal affects projected future habitat availability for a threatened carnivore, the fisher (Pekania [Martes] pennanti). We used non-invasive genetic sampling to detect fisher across their historical distribution in Montana and Idaho. This survey included 4846 non-invasive hair snares, of which 288 identified fishers through mitochondrial DNA analysis. We modeled the distribution of fisher across western Montana and northern Idaho using a suite of vegetative, topographic, and climatic...
