Description: The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the "Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" “Standard” (http://pubs.usgs.gov/tm/11/a3/). Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit (6th level) for the entire United States. Some areas may also include additional subdivisions representing the 14- and 16-digit hydrologic unit (HU). At a minimum, the HUs are delineated at 1:24,000-scale in the conterminous United States, 1:25,000-scale in Hawaii, Pacific basin and the Caribbean, and 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards (NMAS). Higher resolution boundaries are being developed where partners and data exist and will be incorporated back into the WBD. WBD data are delivered as a dataset of polygons and corresponding lines that define the boundary of the polygon. WBD polygon attributes include hydrologic unit codes (HUC), size (in the form of acres and square kilometers), name, downstream hydrologic unit code, type of watershed, non-contributing areas, and flow modifications. The HUC describes where the unit is in the country and the level of the unit. WBD line attributes contain the highest level of hydrologic unit for each boundary, line source information and flow modifications.

Description: 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 information. Given the scope of the project, the existing Northeast Aquatic Habitat Classification System (Olivero and Anderson 2008) and GIS map (NHD Plus V1. 1:100,000) was used as the foundation. Resources were not available for remapping at a finer scale or reanalyzing the detailed stream and river types in the region, although a new tidal stream and river class was developed as part of this simplification project. The simplification method was developed with guidance from a steering committee of state freshwater ecologists. The steering committee recommended using a simplification framework based on the NY Freshwater Blueprint (White et al. 2011). To keep the number of regional types to a manageable number yet still maintain key ecological information, we developed a 58 type simplification that used size, gradient, geology, temperature, and tidal classes. However, the above five variables were not used to define every habitat type. For example, headwaters through small rivers were split using size, gradient, geology and temperature, while medium to large rivers were only split by gradient and temperature. Tidal habitats were split by three size classes. This simplification yielded a set of stream and river types that many felt would be useful to agencies and managers across the region. For the general audience of the habitat guide, the 58 types were further collapsed into 23 major types. The 23 major types were created by collapsing the geology classes for headwaters through small rivers and collapsing the gradient classes for medium to large rivers. Although the expected natural community types within the various geology classes of headwaters through small rivers will vary, particularly among the macroinvertebrate and aquatic plant communities, we wanted to focus the general audience on the more dominant patterns of size, gradient, and temperature for headwaters through small rivers. Similarly for medium to large rivers, we focused on the dominant patterns of size and temperature variation within these larger rivers. The habitat guide maps still show the finer distribution of the full 58 types using different colors for geology types within headwaters-small rivers and different colors for gradient classes for medium-large rivers, however the accompanying habitat guide descriptions, associated species, and condition statistics reflect patterns across the simplified 23 types.

Description: The USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public land and voluntarily provided private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastre Theme (https://communities.geoplatform.gov/ngda-cadastre/). The PAD-US is an ongoing project with several published versions of a spatial database including areas dedicated to the preservation of biological diversity, and other natural (including extraction), recreational, or cultural uses, managed for these purposes through legal or other effective means. The database was originally designed to support biodiversity assessments; however, its scope expanded in recent years to include all public and nonprofit lands and waters. Most are public lands owned in fee (the owner of the property has full and irrevocable ownership of the land); however, long-term easements, leases, agreements, Congressional (e.g. 'Wilderness Area'), Executive (e.g. 'National Monument'), and administrative designations (e.g. 'Area of Critical Environmental Concern') documented in agency management plans are also included. The PAD-US strives to be a complete inventory of public land and other protected areas, compiling “best available” data provided by managing agencies and organizations. The PAD-US geodatabase maps and describes areas using over twenty-five attributes and five feature classes representing the U.S. protected areas network in separate feature classes: Fee (ownership parcels), Designation, Easement, Marine, Proclamation and Other Planning Boundaries. Five additional feature classes include various combinations of the primary layers (for example, Combined_Fee_Easement) to support data management, queries, web mapping services, and analyses. This PAD-US Version 2.1 dataset includes a variety of updates and new data from the previous Version 2.0 dataset (USGS, 2018 https://doi.org/10.5066/P955KPLE ), achieving the primary goal to "Complete the PAD-US Inventory by 2020" (https://www.usgs.gov/core-science-systems/science-analytics-and-synthesis/gap/science/pad-us-vision) by addressing known data gaps with newly available data. The following list summarizes the integration of "best available" spatial data to ensure public lands and other protected areas from all jurisdictions are represented in PAD-US, along with continued improvements and regular maintenance of the federal theme. Completing the PAD-US Inventory: 1) Integration of over 75,000 city parks in all 50 States (and the District of Columbia) from The Trust for Public Land's (TPL) ParkServe data development initiative (https://parkserve.tpl.org/) added nearly 2.7 million acres of protected area and significantly reduced the primary known data gap in previous PAD-US versions (local government lands). 2) First-time integration of the Census American Indian/Alaskan Native Areas (AIA) dataset (https://www2.census.gov/geo/tiger/TIGER2019/AIANNH) representing the boundaries for federally recognized American Indian reservations and off-reservation trust lands across the nation (as of January 1, 2020, as reported by the federally recognized tribal governments through the Census Bureau's Boundary and Annexation Survey) addressed another major PAD-US data gap. 3) Aggregation of nearly 5,000 protected areas owned by local land trusts in 13 states, aggregated by Ducks Unlimited through data calls for easements to update the National Conservation Easement Database (https://www.conservationeasement.us/), increased PAD-US protected areas by over 350,000 acres. Maintaining regular Federal updates: 1) Major update of the Federal estate (fee ownership parcels, easement interest, and management designations), including authoritative data from 8 agencies: Bureau of Land Management (BLM), U.S. Census Bureau (Census), Department of Defense (DOD), U.S. Fish and Wildlife Service (FWS), National Park Service (NPS), Natural Resources Conservation Service (NRCS), U.S. Forest Service (USFS), National Oceanic and Atmospheric Administration (NOAA). The federal theme in PAD-US is developed in close collaboration with the Federal Geographic Data Committee (FGDC) Federal Lands Working Group (FLWG, https://communities.geoplatform.gov/ngda-govunits/federal-lands-workgroup/); 2) Complete National Marine Protected Areas (MPA) update: from the National Oceanic and Atmospheric Administration (NOAA) MPA Inventory, including conservation measure ('GAP Status Code', 'IUCN Category') review by NOAA; Other changes: 1) PAD-US field name change - The "Public Access" field name changed from 'Access' to 'Pub_Access' to avoid unintended scripting errors associated with the script command 'access'. 2) Additional field - The "Feature Class" (FeatClass) field was added to all layers within PAD-US 2.1 (only included in the "Combined" layers of PAD-US 2.0 to describe which feature class data originated from). 3) Categorical GAP Status Code default changes - National Monuments are categorically assigned GAP Status Code = 2 (previously GAP 3), in the absence of other information, to better represent biodiversity protection restrictions associated with the designation. The Bureau of Land Management Areas of Environmental Concern (ACECs) are categorically assigned GAP Status Code = 3 (previously GAP 2) as the areas are administratively protected, not permanent. More information is available upon request. 4) Agency Name (FWS) geodatabase domain description changed to U.S. Fish and Wildlife Service (previously U.S. Fish & Wildlife Service). 5) Select areas in the provisional PAD-US 2.1 Proclamation feature class were removed following a consultation with the data-steward (Census Bureau). Tribal designated statistical areas are purely a geographic area for providing Census statistics with no land base. Most affected areas are relatively small; however, 4,341,120 acres and 37 records were removed in total. Contact Mason Croft (masoncroft@boisestate) for more information about how to identify these records.

Description: This dataset represents dam and road stream crossings in the northeastern United States (ME, NH, VT, MA, CT, RI, NY, PA, NJ, DE, MD, VA, WV, DC). This data was complied as part of the North Atlantic Aquatic Connectivity Collaborative (NAACC) for the 2016 version of the Northeast Aquatic Connectivity anlaysis (http://maps.freshwaternetwork.org/northeast). The road-stream crossing data in this dataset compiled by the NAACC (https://streamcontinuity.org/) and its contributors. Dam data was compiled for the original Northeast Aquatic Connectivity study (http://rcngrants.org/content/northeast-aquatic-connectivity) and revised based on input from the Northeast Aquatic Connectivity project workgroup, updates from state dam databases, and removals from American River's dam removal database (https://www.americanrivers.org/threats-solutions/restoring-damaged-rivers/dam-removal-map). Both road-stream crossings and dams were spatially linked to flowlines in the USGS National Hydrography Plus (NHD-Plus) v2 1:100,000 stream dataset. These barriers form the primary input dataset for the 2016 version of the Northeast Aquatic Connectvitiy analysis. (http://maps.freshwaternetwork.org/northeast). To this barrier dataset, 38 ecologically-relevant metrics were calculated and used in the barrier prioritization.

Description: This dataset represents dam and road stream crossings in the northeastern United States (ME, NH, VT, MA, CT, RI, NY, PA, NJ, DE, MD, VA, WV, DC). This data was complied as part of the North Atlantic Aquatic Connectivity Collaborative (NAACC) for the 2016 version of the Northeast Aquatic Connectivity anlaysis (http://maps.freshwaternetwork.org/northeast). The road-stream crossing data in this dataset compiled by the NAACC (https://streamcontinuity.org/) and its contributors. Dam data was compiled for the original Northeast Aquatic Connectivity study (http://rcngrants.org/content/northeast-aquatic-connectivity) and revised based on input from the Northeast Aquatic Connectivity project workgroup, updates from state dam databases, and removals from American River's dam removal database (https://www.americanrivers.org/threats-solutions/restoring-damaged-rivers/dam-removal-map). Both road-stream crossings and dams were spatially linked to flowlines in the USGS National Hydrography Plus (NHD-Plus) v2 1:100,000 stream dataset. These barriers form the primary input dataset for the 2016 version of the Northeast Aquatic Connectvitiy analysis. (http://maps.freshwaternetwork.org/northeast). To this barrier dataset, 38 ecologically-relevant metrics were calculated and used in the barrier prioritization.

Description: This dataset represents dam and road stream crossings in the northeastern United States (ME, NH, VT, MA, CT, RI, NY, PA, NJ, DE, MD, VA, WV, DC). This data was complied as part of the North Atlantic Aquatic Connectivity Collaborative (NAACC) for the 2016 version of the Northeast Aquatic Connectivity anlaysis (http://maps.freshwaternetwork.org/northeast). The road-stream crossing data in this dataset compiled by the NAACC (https://streamcontinuity.org/) and its contributors. Dam data was compiled for the original Northeast Aquatic Connectivity study (http://rcngrants.org/content/northeast-aquatic-connectivity) and revised based on input from the Northeast Aquatic Connectivity project workgroup, updates from state dam databases, and removals from American River's dam removal database (https://www.americanrivers.org/threats-solutions/restoring-damaged-rivers/dam-removal-map). Both road-stream crossings and dams were spatially linked to flowlines in the USGS National Hydrography Plus (NHD-Plus) v2 1:100,000 stream dataset. These barriers form the primary input dataset for the 2016 version of the Northeast Aquatic Connectvitiy analysis. (http://maps.freshwaternetwork.org/northeast). To this barrier dataset, 38 ecologically-relevant metrics were calculated and used in the barrier prioritization.

Description: The U.S. Geological Survey (USGS) produced a comprehensive database of digital vector shorelines by compiling shoreline positions from pre-existing historical shoreline databases and by generating historical and modern shoreline data. Shorelines are compiled by state and generally correspond to one of four periods: 1800s, 1920s-1930s, 1970s, and 1998-2002. Each shoreline may represent a compilation of data from one or more sources for one or more dates provided by one or more agencies. Shoreline within the Long Island Sound was selected for the Living Shorelines memo.

Description: Boat launches are state, municipal, local, or privately owned sites that provide boating access to coastal waters, lakes, ponds, and rivers. Sites may be ramps suitable for trailered orcarried-in boats, or landing facilities. Locations only suitable for shoreline fishing access andnot boat put-in were not included in this dataset.This dataset is comprised of individual datasets provided by various sources in the northeastern U.S. Boat launch specific data was extracted from the source data, duplicate records were removed based on point location accuracy and data acquisition date, and datasets were merged into a single regional product. Points outside a 10km coastal buffer were eliminated. Based on source data, this product may not indicate private or public access for a given launch site and users are advised to determine accessibility prior to using a site.
