Description:

Abstract:

Essential Fish Habitat (EFH) is defined as those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity (16 U.S.C. 1802(10)). Waters include aquatic areas and their associated physical, chemical, and biological properties that are used by fish and may include aquatic areas historically used by fish where appropriate; substrate includes sediment, hard bottom, structures underlying the waters, and associated biological communities; necessary means the habitat required to support a sustainable fishery and the managed species' contribution to a healthy ecosystem; and spawning, breeding, feeding, or growth to maturity covers a species' full life cycle.
This particular layer represents an overlay of EFH polygons for numerous species. The Nature Conservancy obtained individual EFH layers from NOAA. This layer does not represent EFH for individual species but rather the number of overlapping EFH in any given location. The following species are included:
American Plaice, Atlantic Cod, Atlantic Halibut, Atlantic Herring, Atlantic Sea Scallop, Atlantic Wolffish, Barndoor Skate, Black Sea Bass, Bluefish, Butterfish, Clearnose Skate, Haddock, Little Skate, Longfin Inshore Squid, Mackerel, Monkfish, Northern Shortfin Squid, Ocean Pout, Offshore Hake, Pollock, Quahog, Redfish, Red Crab, Red Hake, Rosette Skate, Scup, Silver Hake, Smooth Skate, Spiny Dogfish, Surfclam, Summer Flounder, Tilefish, Thorny Skate, White Hake, Windowpane Flounder, Winter Flounder, Winter Skate, Witch Flounder, and Yellowtail Flounder. Note that these environmental data and related items of information have not been formally disseminated by NOAA and do not represent and should not be construed to represent any agency determination, view, or policy.

Purpose:

Originally developed for the Mid-Atlantic Regional Council on the Ocean (MARCO) web mapping portal to demonstrate where there are numerous overlapping EFH designations.

Data_Quality_Information:

Attribute_Accuracy:

Completeness_Report: Only the 39 species managed by NMFS in the Northeast and Mid-Atlantic are included.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Feature class geometry is based on 10 minute by 10 minute grid squares. Note that biological/ocean current data by their very nature are considered dynamic, which should be understood when considering the positional accuracy of vector digital objects representing these resources.

Process_Step:

Process_Description:

The Nature Conservancy received EFH data from NOAA with attributes for each individual species and for each species life stage for most species. The attribute table was edited in Excel to include only a single attribute for each species indicating the life stages present where applicable. A sum of all species present at a given location was also calculated. A species was counted in this sum if one or more life stages were present.
