- Abstract:
-
DEP maintains a Stream Network data layer that is a subset of the USGS 1:24,000 high-resolution National Hydrography Dataset (NHD). In Version 3.3 of the Landscape Project, stream and water body centerlines from the NHD Streams 2002 data layer are used to represent freshwater mussel habitat.Water body centerline and stream centerline data are valued exclusively by freshwater mussel species occurrence areas while other aquatic species habitats are represented with polygons from the Species-Based Habitat layer. In order to form representative "patches" of habitat from the NHD Streams 2002 layer, centerlines were broken at the following points:The confluence of two or more streamsThe inflow/outflow of a water bodyStretches of stream intersected by a mussel SOA are valued as habitat. All valued streams are buffered by 0.75 kilometers upstream and downstream. The 0.75 kilometer distance is chosen as a conservative buffer estimate because scientific literature, which is based largely upon larval transport by host fishes, indicates that if there are two occurrences within two kilometers of each other (assuming unsuitable habitat between), these occurrences should be considered as part of the same local population (NatureServe 2011). In the cases where stream buffers of separate occurrences of the same species met, either upstream or downstream, the stream segments between those occurrences are also valued for that species. In addition, in cases where dams are barriers the extent of stream valued was limited.
- Purpose:
-
The Landscape Project was designed to provide users with peer-reviewed, scientifically sound information that transparently documents threatened and endangered species habitat. Landscape Project data are easily accessible and can be integrated with the planning, protection and land management programs of non-government organizations and private landowners and at every level of government- federal, state, county and municipal. Landscape maps and overlays provide a basis for proactive planning, such as the development of local habitat protection ordinances, zoning to protect critical wildlife areas, management guidelines for imperiled species conservation on public and private lands, and land acquisition projects.
Most importantly, the information that is readily available in the Landscape Project can be used for planning purposes before any actions such as proposed development, resource extraction (e.g. timber harvests) or conservation measures occur. The maps help increase predictability for local planners, environmental commissions, and developers and help facilitate local land use decisions that appropriately site and balance development and habitat protection. The Landscape Project maps allow the regulated public to anticipate potential environmental regulation in an area and provide some level of assurance regarding areas where endangered, threatened or species of special concern are not likely to occur, affording predictability to the application and development process. Thus, Landscape Project maps can be used proactively by regulators, planners and the regulated public in order to minimize conflict and protect species. This minimizes time and money spent attempting to resolve after-the-fact endangered and threatened species issues.

In August 2010, NJDEP completed the statewide attribute transfer of the USGS 1:24000 high-resolution National Hydrography Dataset (NHD) to the 2002 Waterbody and Stream Network data layers. This data is a subset of the complete NHD geodatabase and includes only features within New Jersey borders. The NHDWaterbody2002 layer combines NHDArea and NHDWaterbody feature classes. The NHDStreams2002 includes only the NHDFlowline feature class for New Jersey.
Digitizing of this data was initially done by Aerial Information Systems, Inc., Redlands, CA, under direction of the New Jersey Department of Environmental Protection (NJDEP), Bureau of Geographic Information System (BGIS).
Conflation of USGS 1:24,000 High resolution NHD attributes was done by Data Enhancement Services, LLC (DES) partnered with Civil Solutions. This statewide conflation of NHD High resolution information was completed in 2010. All QA/QC was done by NJDEP, Bureau of GIS and USGS.

Rank 1 is assigned to species-specific habitat patches that meet habitat-specific suitability requirements such as minimum size or core area criteria for endangered, threatened or special concern wildlife species, but that do not intersect with any confirmed occurrences of such species (see Appendix V for descriptions of all habitat-specific suitability requirements). Rank 1 habitat patches without documented occurrences are not necessarily absent of imperiled or special concern species. Patches with a lack of documented occurrences may not have been systematically surveyed. Thus, the Rank 1 designation is used for planning purposes, such as targeting areas for future wildlife surveys.

In Version 3.3 a species-based habitat method is implemented by associating each species with a specific set of LULC classes according to the habitat needs of the species. Detailed LULC class delineations allow for an accurate representation of imperiled and special concern species habitat by providing ENSP biologists with the ability to designate a specific set of LULC classes for each individual species-feature label combination. Each species-habitat association is developed by performing a review of scientific literature and/or from information obtained through ENSP research and expert opinion. In addition, a special analysis of the LULC for species and their feature label components was used to guide the selection of particular LULC classes for the creation of species-specific patches of habitat (Appendix IV).
In order to create species-based patches of habitat, the relevant LULC polygons from the Landscape base layer are combined into a potential habitat layer specific to each species-feature label. Spatially explicit species occurrence data that meet the criteria required for inclusion in the Landscape Project are then exported from the Biotics database and a species occurrence area (SOA) is applied for every feature label assigned to a species. SOAs are then overlaid onto species-specific habitat patches and patches are classified, or valued, based on the status of the species present as follows:
Rank 5 is assigned to species-specific habitat patches containing one or more occurrences of wildlife listed as endangered and threatened pursuant to the Federal Endangered Species Act of 1973.
Rank 4 is assigned to species-specific habitat patches with one or more occurrences of State endangered species.
Rank 3 is assigned to species-specific patches containing one or more occurrences of State threatened species.
Rank 2 is assigned to species-specific habitat patches containing one or more occurrences of species considered to be species of special concern. Rank 1 is assigned to species-specific habitat patches that meet habitat-specific suitability requirements such as minimum size or core area criteria for endangered, threatened or special concern wildlife species, but that do not intersect with any confirmed occurrences of such species (see Appendix V for descriptions of all habitat-specific suitability requirements).
Rank 1 habitat patches without documented occurrences are not necessarily absent of imperiled or special concern species. Patches with a lack of documented occurrences may not have been systematically surveyed. Thus, the Rank 1 designation is used for planning purposes, such as targeting areas for future wildlife surveys.
A SOA will value habitat that it overlays only if that habitat is appropriate for the species. Habitat patches ranked 2, 3, 4, or 5 intersect with or contain at least one documented SOA. Since imperiled species are typically not abundant across the landscape, a single occurrence may represent a significant portion of the local population and often indicates the presence of a larger population within a habitat patch. The Landscape Project habitat patch mapping approach is designed to capture and represent the habitat needed to support the local population indicated by the individual SOA.
In the delineation of Species-Based Habitat, each species-feature label combination is grouped into a Patch Type, or category that describes the method employed to form the valued habitat area from polygons in the Landscape base layer. In addition, for each LULC class selected for a particular species-feature label combination, a LULC Treatment, or rule, is applied that determines how polygons of a LULC class will interact with a SOA and/or with polygons of other LULC classes in order to construct patches of habitat. The four general patch types are described below and the LULC Treatments are defined in Appendix V. For those species-feature label combinations that utilize variations, or subtypes, of the four general types, an explanation of the subtype is also included within Appendix V.
Each species-feature label combination is grouped into one of the following patch type categories.
Limited Extent polygons from a select set of LULC classes are valued upon intersection with a SOA. Once the valued habitat area is identified, any internal holes or gaps containing polygons of selected LULC classes are also valued if they are completely enclosed by, and contiguous with, the valued area.
Contiguous Area polygons from a select set of LULC classes are dissolved/combined into contiguous areas and valued upon intersection with a SOA.
Cardinal-Proximate polygons from an initial, or cardinal, set of LULC classes are valued upon intersection with a SOA and then polygons from a second, proximate set of LULC classes are valued based on a spatial relationship (e.g., adjacency) with polygons from the cardinal set of LULC classes and/or a SOA. Once the valued habitat area is identified, any internal holes or gaps containing polygons of selected LULC classes are also valued if they are completely enclosed by, and contiguous with, the valued area.
Stream Centerline stream centerlines are valued upon intersection with a SOA. In Version 3.3 of the Landscape Project, only freshwater mussel species utilize the Stream Centerline patch type, described more thoroughly in the next section.
DEP maintains a Stream Network data layer that is a subset of the USGS 1:24,000 high-resolution National Hydrography Dataset (NHD). In Version 3.3 of the Landscape Project, stream and water body centerlines from the NHD Streams 2002 data layer are used to represent freshwater mussel habitat.
Water body centerline and stream centerline data are valued exclusively by freshwater mussel species occurrence areas while other aquatic species habitats are represented with polygons from the Species-Based Habitat layer. In order to form representative "patches" of habitat from the NHD Streams 2002 layer, centerlines were broken at the following points:
The confluence of two or more streams
The inflow/outflow of a water body
Stretches of stream intersected by a mussel SOA are valued as habitat. All valued streams are buffered by 0.75 kilometers upstream and downstream. The 0.75 kilometer distance is chosen as a conservative buffer estimate because scientific literature, which is based largely upon larval transport by host fishes, indicates that if there are two occurrences within two kilometers of each other (assuming unsuitable habitat between), these occurrences should be considered as part of the same local population (NatureServe 2011). In the cases where stream buffers of separate occurrences of the same species met, either upstream or downstream, the stream segments between those occurrences are also valued for that species. In addition, in cases where dams are barriers the extent of stream valued was limited.
