Tidal marshes serve a variety of important functions valued by Maine communities. Unfortunately, tidal marsh habitats are highly vulnerable to damage or loss from sea level rise. Scientists expect marsh habitats will be more frequently flooded in the future and marsh vegetation lost or significantly altered as a result. Salt marshes do, however, have the ability to ‘migrate’ landward with sea level rise-induced changes in shoreline position. The potential and ability for marsh migration is crucial to sustaining these important ecosystems and their functions for the future.

NOTE: The data are available online four times based on four different attributes (the current, plus 2 degrees C, plus 4 degrees C, and plus 6 degrees C probability of occurrence), the dataset is the same and the download includes the layer files for all the attributes, you do NOT need to download the data more than once.

The zipped folder attached to this entry is an archive of the work of the *Connect the Connecticut* "core team," which met from 2014 to 2016. The archive includes records of the meetings of the core team including associated presentations and decisions. The core team also worked under two sub-teams, the Aquatics team and the Terrestrial team; records of these teams are also included in the archive.

Probability of Development, Northeast U.S. is one of a suite of products from the Nature’s Network project (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.

Large forest blocks are important features on the landscape and worthy of conservation attention. Maintenance of large blocks of intact habitat is perhaps the most oft recommended biodiversity conservation strategy. We created a map of large forest blocks by selecting all of the forest formations from the Ecological Systems dataset and converting this raster coverage into a polygon coverage using ArcMap. We then used the area function within the resulting attribute table to calculate areas of forest habitats across the state.

This dataset represents untransformed average annual daily traffic (AADT), or vehicles per day, throughout the Northeastern United States circa 2010.

Detailed documentation for the methods to derive the dataset are available from the Ancillary Data document: http://jamba.provost.ads.umass.edu/web/LCC/AncillaryData.pdf

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.

Soil pH measures acidity, which affects nutrient uptake by plants. The most common soil laboratory measurement of pH is the 1:1 water method. A crushed soil sample is mixed with an equal amount of water, and a measurement is made of the suspension. For each soil layer, this attribute is actually recorded as three separate values in the database. A low value and a high value indicate the range of this attribute for the soil component. A "representative" value indicates the expected value of this attribute for the component. For this soil property, only the representative value is used.

This dataset measures the total amount of above-ground live biomass in forested systems, which is an important attribute of forested communites and an indicator of successional development, and an important habitat attribute for many forest-associated wildlife species. The dataset is derived from a combination of remote sensing products derived from multi-temporal Landsat TM data and Forest Inventory and Analysis (FIA) plot data and forest succession models derived from FIA plot data.

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.

These datasets are a depiction of the potential capability of the landscape throughout the Northeastern United States to provide suitable future conditions for the 29 representative species using 2080 climate projections with the 2010 landscape. These products are intended to isolate the effect of climate change on the species distribution by not incorporating urband growth into the future landscape. The data are intended to be used in conjunction with the landscape capability datasets, for each respective species, based on environmental conditions existing in approximately 2010.

This dataset was last updated 05/2016. This version was updated using DSLland Version 3.1. The update to DSLland Version 3.1 from Version 3.0 is the addition of a lakes and ponds classification.

The download for this dataset includes the full Northeastern Aquatic Habitat Classification System (NAHCS): stream size, stream temperature, stream gradient, stream geology, lakes, and catchments.

This online database (https://www.streamcontinuity.org/cdb2/naacc_search_crossing.cfm) serves as a common repository for road-stream crossing assessment data assembled by the North Atlantic Aquatic Connectivity Collaborative (NAACC). Both a network of partners and a source of shared resources, the NAACC offers a collaborative framework for taking on the critical task of assessing and upgrading the hundreds of thousands of outdated road-stream crossings across the region that represent barriers to wildlife movement

The three components of benthic data used for creation of the Ecological Marine Units (EMUs) and the Benthic Habitat Types (combinations of EMUs considered with their species assemblages)
 for the Northwest Atlantic Marine Ecoregional Assessment.

Download includes: Bathymetry, Benthic Habitats, Benthic Sediment, Ecological Marine Units, Seabed Forms, and Ecoregional Boundaries.

This is a 30 meter grid that maps upland and wetland wildlife habitats/ecological systems for the Northeastern US, including all 13 states from Maine to Virginia, west to New York, Pennsylvania and West Virginia, and for the Maritime provinces of Canada (Nova Scotia, Prince Edward Island, and New Brunswick) and southeastern Quebec. Mapped habitat types are drawn from the Northeastern Terrestrial Habitat Classification System (NETHCS) and from some ecological system types identifed by Canadian ecologists as being unique to Canada.

NOTE - This map contains two datasets: "Important Anadromous Fish Habitat, Northeast U.S." and "Atlantic Salmon Rearing Areas, Maine"

The Prioritization Tool is a web application for identifying the best opportunities to restore rare and threatened habitats for Species of Greatest Conservation Need (SGCN) and other species in the Northeast. The goal underlying the development of the restoration tool was to identify areas of degraded habitat having high restoration potential, which if restored would contribute to the network of connected, intact, and resilient sites for biodiversity conservation mapped by Nature’s Network.

Soil depth (cm) affects communities primarily because shallow soils (usually on steep slopes or ridgetops) limit deep-rooted plants. A "restrictive layer" is a nearly continuous layer that has one or more physical, chemical, or thermal properties that significantly impede the movement of water and air through the soil or that restrict roots or otherwise provide an unfavorable root environment. if no restrictive layer is described in a map unit, it is represented by the ">200' depth class, This attribute is actually recorded as three separate values in the database.
