The download for this dataset includes TNC’s full Northeastern Aquatic Habitat Classification System: stream size, stream temperature, stream gradient, stream geology, lakes and catchments. This dataset represents the results (9/30/2008) of the Northeastern Aquatic Habitat Classification System (NAHCS) GIS map for streams and rivers. This classification focused on mapping a stream habitat types across 13 northeastern states (ME, NH, VT, MA, CT, RI, NY, NJ, PA, MD, DC, DE, VA, WV). Stream and river centerlines were extracted from the USGS National Hydrography Dataset Plus (NH-Plus) 2006 1:100,000 data. These reaches were attributed and placed into classes representing their biopysical setting in terms of stream...
Point nesting data, Environmental Sensitivity Index (ESI) importance and nesting areas and sightings per unit effort (SPUE) for the three species of turtles - Green sea turtle, Leatherback turtle, and Loggerhead turtle.
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.

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...

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...

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...
Includes: Seasonal data on Zooplankton - biomass data were obtained from the COPEPOD database (NOAA) for 1977-2007, Chlorophyll - measured to determine phytoplankton concentration, Sea Surface Temperature - data were extracted from three dimensional climatologies representing 28 years from 1980 - 2007, averaged, and interpolated with ordinary kriging to produce a smooth surface, and Stratification - data helps describe the physical environment of the water column near the surface. These data help to understand the seasonal patterns of mixing and stratification that help to determine areas of high productivity and benthic-pelagic coupling.
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.

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)....
Ecological Marine Units (EMUs) are the three-way combination of physical variables - depth, sediment grain size, and seabed forms. The breaks in bathymetry and substrate grain size are based on the ecological thresholds revealed by the benthic organism relationships. Download includes: Bathymetry, Benthic Habitats, Benthic Sediment, Ecological Marine Units, Seabed Forms, and Ecoregional Boundaries.
This report describes an effort of a team of 60 scientists led by The Nature Conservancy (TNC) to identify the places where nature’s own natural resilience is the highest. Thanks to the land’s diverse topography, bedrock, and soil, these climate-resilient sites are more likely to sustain native plants, animals, and natural processes into the future, becoming natural strongholds for diversity. To map their locations, The Nature Conservancy-led team used over 70 new and comprehensive datasets to find places that are buffered from the effects of climate change because the site offers a wide range of micro-climates within a highly connected area. In 2015, the results were published in a leading conservation science...
In the Northeast United States region, efforts are underway to better organize and integrate marine ecosystem data to support ocean planning and management efforts. An important step in this process is translating existing data to a common language so that heterogeneous data can be viewed in a common framework region-wide to better facilitate decision-making.In September 2013, the Northeast Regional Ocean Council Habitat Working Group agreed that crosswalking (i.e., translating) existing seafloor habitat data to the Federal Geographic Data Committee (FGDC)-approved United States Coastal and Marine Ecological Classification Standard (CMECS) should be a priority. At that time, the work presented here was already well...
