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...
Abstract Unpaved forest roads remain a pervasive disturbance on public lands and mitigating sediment from road networks remains a priority for management agencies. Restoring roaded landscapes is becoming increasingly important for many native coldwater fishes that disproportionately rely on public lands for persistence. However, effectively targeting restoration opportunities requires a comprehensive understanding of the effects of roads across different ecosystems. Here, we combine a review and a field study to evaluate the status of knowledge supporting the conceptual framework linking unpaved forest roads with streambed sediment. Through our review, we specifically focused on those studies linking measures of...
The Northeast Regional Conservation Framework Workshop (“Albany II”) was held in Albany, New York on June 14-16, 2011 with eighty-six (86) participants, representing a cross-section of 13 state agencies, six federal agencies and 12 nongovernmental organizations or universities. The workshop was convened and sponsored jointly by the Northeast Association of Fish and Wildlife Agencies (NEAFWA) and the Landscape Conservation Cooperatives (LCCs) in the Northeast Region. The specific objectives of the workshop were to: Review, synthesize, evaluate, and present Regional Conservation Needs (RCN) and initial LCC projects completed or underway; Increase understanding and engagement by state and other conservation partners...

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...

Background Streams and rivers are an important environmental resource and provide water for many human needs. Streamflow is a measure of the volume of water carried by rivers and streams. Changes in streamflow can directly influence the supply of water available for human consumption, irrigation, generating electricity, and other needs. In addition, many plants and animals depend on streamflow for habitat and survival. Streamflow naturally varies over the course of a year. For example, rivers and streams in many parts of the country have their highest (peak) flow when snow melts in the spring. The amount of streamflow is important because high flows can cause erosion and damaging floods, while very low flows...

This dataset consists of the current distribution (2000s) of mangrove forests in the southeastern U.S. This dataset was created from the current best available mangrove data on a state specific basis. Florida mangrove data was extracted from Florida Landuse Land Cover Classification System (FLUCCS). For Louisiana, we used observations of mangrove stands from aerial surveys by Michot et al. (2010). Mangrove presence in Texas came from maps produced by Sherrod & McMillan (1981) and the NOAA Benthic Habitat Atlas of Coastal Texas (Finkbeiner et al. 2009). Please note that this map depicts the distribution of mangrove forests and not mangrove individuals. More detailed information on this dataset is available in Osland...

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their...

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...

Information on the nature and distribution of permafrost is critical to assessing the response of Arctic ecosystems to climate change, because thawing permafrost under a warming climate will cause thaw settlement and affect micro-topography, surface water redistribution and groundwater movement, soil carbon balance, trace gas emissions, vegetation changes, and habitat use. While a small-scale regional permafrost map is available, as well as information from numerous site-specific large-scale mapping projects, landscape-level mapping of permafrost characteristics is needed for regional modeling and climate impact assessments. The project addresses this need by: (1) compiling existing soil/permafrost data from available...
This work provides a flexible and scalable framework to assess the impacts of climate change on streamflow and stream temperature within the North Atlantic Landscape Conservation Cooperative (NALCC) region. This is accomplished through use of lumped parameter, physically-based, conceptual hydrologic and stream temperature models formulated in a hierarchical Bayesian framework. This allows for model predictions of streamflow and temperature at ungaged locations and a formal accounting of model estimate uncertainty at each location, something not previously achieved in these models. These environmental models will also link seamlessly with the land use and fish models. The final products of this project will provide:...
