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...
Marine Mammal data: assessed, combined and converted from seasonal species sightings into 10-minute squares. Individual grids were then multiplied by 1000 and divided by seasonal effort grids previously generated by the U.S. Navy. The resulting sightings per unit effort (SPUE) grids were used to identify important areas within the Ecoregion for each species.

To create a wall-to-wall surface of landscape permeability we used the software CIRCUITSCAPE (McRae and Shah 2009), an innovative program that models species and population movements as if they were electric current flowing through a landscape of variable resistance. Circuit modeling is conceptually aligned with the concept of landscape permeability because it recognizes that movement through a landscape is affected by a variety of impediments, and it quantifies the degree and the directional outcomes of the compounding effects. One output is a “flow” map that shows the behavior of directional flows and highlights concentration areas and pinch-points.The results can highlight locally and regionally significant places...

Consistent and accurate landscape datasets are important foundational products for ecological analyses and for understanding and anticipating the effects of climate change on forested, agricultural, and freshwater systems across the U.S. and Canada. The objective of this project was to extend an existing terrestrial habitat map of the north Atlantic U.S. to Atlantic Canada and southern Quebec, using and modeling field-collected data combined with national and provincial datasets. This GIS map 1) provides a foundation upon which further research, such as species vulnerability analyses, can advance, 2) allows each relevant state and province to identify terrestrial habitats consistently across borders, 3) allows for...
Includes: Coastal Habitat, Coastal Marine Ecological Classification Standard (CMECS), Shoreline Units - represents a parsing tool to help compare and contrast geographies with the understanding that boundary changes, or splitting/lumping of areas may be desirable when developing conservation approaches at more localized geographies, Coastal Vulnerability Index (CVI) - provides insight into the relative potential of coastal change due to future sea-level rise, and Eelgrass.

These datasets are part of a suite of products from the Nature’s Network project. 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. The data depict the relative resilience or vulnerability of every coastal site to six possible scenarios of sea level rise (1 to 6 feet). Other data from this project are available in the Nature’s Network gallery: https://nalcc.databasin.org/galleries/8f4dfe780c444634a45ee4acc930a055.

Species richness of large pelagic fish - The richness of target species values were calculated to outline the diversity of the species in each ten minute square. The essential fish habitat (EFH) metrics were developed to understand how much of the region is considered EFH and to identify points were EFH for the target species overlapped. The persistence score identifies which target species were observed in the same ten minute square over time. The days fished metrics were calculated to understand the distribution of gillnet, longline, and bottom longline fishing trips.

The objective of this classification was to create a simplified set of stream and river habitat types based on the Northeast Aquatic Habitat Classification System (Olivero and Anderson 2008) and GIS map for 13 northeastern states (ME, NH, VT, MA, RI, CT, NY, PA, NJ, DE, MD, VA, WV, and DC.) that could be used in the Northeast Stream and River Habitat Guide (available at http://nature.ly/HabGuide). The goal was to collapse the existing 258 types down to ~25 types for reporting in the habitat guide. The habitat guide contains a description of each stream and river type, a distribution map, a photo, associated common and rare species, a crosswalk to state aquatic community types, and a summary of current condition...
Resilience concerns the ability of a living system to adjust to climate change, moderate potential damages, take advantage of opportunities, or cope with consequences; in short, the capacity to adapt. The Nature Conservancy’s resilience analysis develops an approach to conserve biological diversity while allowing species and communities to rearrange in response to a continually changing climate. - See more at: http://nature.org/TNCResilience Eastern Division scientists analyzed 393 million acres of land for resilience, stretching from Florida to Maine and adjacent areas of Canada (NOTE - The dataset included in the download was clipped to the Northeast (Region 5), for the original data see: https://nalcc.databasin.org/datasets/c57ec56be4524d81af3491747c865d29)....

Sea levels are expected to rise by one to six feet over the next century, and coastal sites vary markedly in their ability to accommodate such inundation. In response to this threat, scientists from The Nature Conservancy evaluated 10,736 sites in the Northeast and Mid-Atlantic for the size, configuration and adequacy of their migration space, and for the natural processes necessary to support the migration of coastal habitats in response to sea-level rise. The resulting resilience dataset is intended to help natural resource managers, conservationists, and others identify resilient lands for protection and restoration across the North Atlantic coast, and has been integrated into the Nature’s Network conservation...

Landscape permeability is the ability of a land area to allow organisms to move and disperse, equivalent to what some authors call “habitat connectivity.” This project evaluated and mapped the relative landscape permeability for terrestrial organisms across the eastern United States and southeastern Canada, taking into account features that impede natural connectivity such as roads and other development. The analysis assigned locations to categories of diffuse flow (intact, permeable areas that facilitate high levels of dispersal), concentrated flow (large quantities of flow are concentrated through a narrow area), constrained flow (low permeability, with flow following a weak reticulated network), or blocked flow...
