- Abstract:
-
Conservation Focal Areas are key geographic areas for the conservation of wildlife in New Jersey. These are the portions of the landscape regions that are of particular conservation interest to the Division of Fish and Wildlife (DFW) and its conservation partners because they have important habitats and species assemblages, and represent the best opportunities for protecting, restoring, and sustaining New Jersey's wildlife diversity. They also include important opportunities for habitat connectivity, a critical factor in increasing resilience in a changing landscape. DFW will use CFAs to further identify geographically-based threats to New Jersey’s wildlife habitats and develop actions that will address those threats. In addition, DFW will regularly review and improve CFA maps as new data become available and as new insights are shared by the public and conservation partners.
- Purpose:
-
To address broader scale planning needs, the Division of Fish and Wildlife, with input from partners, identified Conservation Focal Areas (CFAs) in New Jersey. CFAs are specific areas of New Jersey’s geography that feature some of the state’s highest value habitats and present important opportunities for effective conservation action. They will allow for the consideration of threats and actions from a geographic perspective that will benefit key wildlife habitats generally and, in turn, virtually all Species of Greatest Conservation Need (SGCN). Further, CFAs include important opportunities for habitat connectivity, a critical factor in increasing resilience in a changing landscape. With their rich mix of important habitats and diverse species assemblages, CFAs are designed to represent some of the best opportunities for protecting, restoring, and sustaining New Jersey’s wildlife diversity.

- Enumerated_Domain_Value_Definition:
-
The Cape May Peninsula Mosaic CFA extends the length of Cape May from the western portion of peninsula up to the north and northwestern boundaries of the Cape May National Wildlife Refuge. It is bounded on the west by the Delaware Bay shoreline between Cape May Canal and Bidwell Creek. The CFA’s habitats are mostly forest, but include shrub, field, and marsh edge. This CFA is particularly important for southbound migratory birds that are funneled into it by prevailing winds. It also supports the majority of the state’s eastern tiger salamander and southern gray treefrog populations.
Habitats on the peninsula are quite fragmented by development and roads, although blocks of land are conserved under state and federal ownership. Many habitats are impaired by invasive plant species that have crowded out native food and cover plants. Conversion of habitat to development threatens the viability of the peninsula as a migratory bird stopover, making beneficial management of remaining parcels important.
This CFA encompasses 4% of the Delaware Bay Landscape Region at 10,393 hectares including 10,097 hectares of terrestrial habitats and 296 hectares of aquatic habitats.

- Enumerated_Domain_Value_Definition:
-
The Delaware Bayshore Marshes CFA’s southern boundary is Bidwell Creek, north of which it extends north and west to the Delaware Bay Landscape Region’s northwestern edge. This CFA includes several disjunct sections, broken at the mouth of the Cohansey River to recognize the contiguous Cohansey River delta and Lower Cohansey River Watershed CFA’s characteristic agricultural-woodland-marsh delta. It is also interrupted to recognize the contiguous Maurice River from its mouth to its upper reaches in the Maurice River Watershed CFA. The Delaware Bayshore Marshes CFA consists primarily of a mixture of low salt marshes and high salt marshes with mudflats and muddy tidal creek shores that are significant for breeding and wintering bald eagles, northern harriers, ospreys, and nesting and wintering waterfowl.
In general, the habitat condition is good, but this system is still recovering from decades of alteration for salt hay production. Formerly impounded salt marshes exhibit land subsidence that can make the marsh more vulnerable to sea level rise. The combination of past human activities, storm effects, and eroding shorelines have resulted in high salt marshes becoming low salt marshes, and the system is vulnerable to accelerated tidal flooding.
This CFA encompasses 13% of the Delaware Bay Landscape Region at 30,267 hectares including 25,736 hectares of terrestrial habitats and 4,531 hectares of aquatic habitats.

- Enumerated_Domain_Value: Delaware Bayshore Forests CFA
- Enumerated_Domain_Value_Definition:
-
The Delaware Bayshore Forests CFA includes the many tracts of wetlands and upland forests that are immediately inland of the Delaware Bayshore Marshes CFA. This CFA is disjunct, interrupted by the Maurice River Watershed CFA, and contains a significant amount of protected land and some of the largest contiguous forest tracts outside of the Pinelands.
These forests are the stronghold for many forest-dependent species, including barred owls and red-shouldered hawks.
In general, the condition of forests in this CFA is good, providing a mixture of forest ages and structure, and a variety of types, from Atlantic white cedar and red maple wetlands to mixed pine-hardwood uplands. Forest management has been very limited, and the primary silviculture focus has been reacting to forest pests like gypsy moth (in the 1990s) and southern pine beetle (in the 2000s). Fragmentation is a threat to this CFA’s important core forests, but to a lesser degree than in some other CFAs.
This CFA encompasses 7% of the Delaware Bay Landscape Region at 16,986 hectares including 16,325 hectares of terrestrial habitats and 661 hectares of aquatic habitats.

- Enumerated_Domain_Value: Lower Great Egg Harbor Watershed CFA
- Enumerated_Domain_Value_Definition:
-
The Lower Great Egg Harbor Watershed CFA is within the harbor’s watershed boundary except for the southern portion, where the Cape May National Wildlife Refuge is part of the Cape May Peninsula Mosaic CFA. This CFA is a mixture of tidal rivers and forests along the tributaries of the Great Egg Harbor, Middle, and Tuckahoe rivers. Beyond the marshes and marsh-forest boundaries, the woodlands are mostly fragmented with the exception of those on state lands. These habitats are significant for breeding and wintering bald eagles, ospreys, and nesting and migrating landbirds and waterbirds.
While the forests in this area are very fragmented, the overarching mosaic of woodlands, marshes, and tidal waterways is a generally healthy system. Water quality is good (the Great Egg Harbor River is a National Wild and Scenic River), but the salt marshes reflect a high degree of grid-ditching as a result of mosquito control activities in the 1950s. Low salt marsh dominates this system, and the limited remaining areas of high salt marsh are threatened by sea level rise and marsh subsidence.
This CFA encompasses 12% of the Delaware Bay Landscape Region at 29,210 hectares including 26,985 hectares of terrestrial habitats and 2,225 hectares of aquatic habitats.

- Enumerated_Domain_Value: Lower Maurice River Watershed CFA
- Enumerated_Domain_Value_Definition:
-
The Lower Maurice River Watershed CFA includes the Maurice River from most of the upper headwaters in northern Cumberland County, the Menantico and Manumuskin tributary rivers, and the Maurice itself. This CFA interrupts the Delaware Bayshore Marshes CFA to recognize the importance of the continuous Maurice River from bay to headwaters. It is characterized by the tidal and brackish waters of multiple tributaries, wide adjacent marshes, and woodlands. It is significant for breeding and wintering bald eagles, nesting ospreys, nesting and wintering waterfowl and waterbirds, and fish populations that support a wide variety of wildlife.
The Maurice River below Willow Grove Lake has excellent water quality (which helped it gain National Scenic and Recreational River status). Wetland habitats are dominated by Phragmites mainly in the brackish portion near Mauricetown. Woodlands along the river are generally in good condition, though fragmented intermittently by development (associated with towns of Millville and Laurel Lake) and pockets of sand mining.
Other portions of the upper watershed are mapped as CFAs within the Pinelands Landscape Region’s Upper Maurice River Watershed (Pinelands) and the Piedmont/Inner Coastal Plain Landscape Regions’ Upper Maurice River Watershed (Piedmont/Inner Coastal Plain). These CFAs share many similarities with the Lower Maurice River Watershed CFA.
This CFA encompasses 10% of the Delaware Bay Landscape Region at 22,750 hectares including 20,449 hectares of terrestrial habitats and 2,301 hectares of aquatic habitats.

- Enumerated_Domain_Value: Lower Cohansey River Watershed CFA
- Enumerated_Domain_Value_Definition:
-
The Lower Cohansey River Watershed CFA is bounded by the Maurice River watershed to the east, and the boundary around the river’s mouth near Bayshore is defined by local roads running from the uplands and bisecting the marsh. The Cohansey River is characterized by the wide tidal estuary and an adjacent marsh-woodlot-agricultural habitat matrix that is exceptional habitat for nesting and wintering bald eagles, northern harriers, ospreys, waterbirds, and wintering waterfowl. Disjunct from the lower river, the CFA includes upper watershed streams that are the Cohansey’s headwaters.
The habitats in the lower Cohansey River are shaped by agricultural use that has reduced structural diversity and degraded water quality. Agriculture dominates both the upper and lower portions of the watershed, covering 60% to 70% of the landscape. As a result, water quality is compromised with elevated phosphorus, bacteria, and high turbidity. Structurally, the marsh-upland ecotone is limited to a narrow woodland separating marshes from planted fields in most of the river below Bridgeton. Phragmites is found in pockets, especially upstream toward Bridgeton.
This CFA encompasses 2% of the Delaware Bay Landscape Region at 5,717 hectares including 4,934 hectares of terrestrial habitats and 783 hectares of aquatic habitats.

Delineating Conservation Focal Areas
The DFW enlisted internal and external stakeholders to inform the selection of GIS data and the method of analysis employed to delineate Conservation Focal Areas (CFAs). A wide variety of GIS data addressing biodiversity and habitat quality, connectivity, rarity and/or impairment within terrestrial, freshwater aquatic, and marine environs were found to be available at statewide and regional scales. To provide a regional context, the Department utilized a variety of conservation planning data compiled by the North Atlantic Landscape Conservation Cooperative (NALCC). Relevant regional data developed by NALCC partners included TNC’s Geospatial Condition Analysis and UMass’s Northeast Index of Ecological Integrity. These and other regional datasets served to complement the host of publicly available conservation-relevant state and local data in New Jersey. As applicable, a number of unpublished or derivative datasets were also utilized in developing CFAs.
The DFW decided to employ a weighted co-occurrence analysis that combines many independent datasets with different metrics to identify areas of high resource value. With some additional spatial optimization techniques, this approach allowed for the identification of specific geographic areas of agreement across a diverse set of geospatial data and metrics. These areas will be the focus of the DFW’s assessment of threats and actions affecting New Jersey’s wildlife habitats, and will identify locations where conservation actions can be carried out to benefit high priority fish and wildlife resources throughout the state.
General GIS Method – Phase 1
Once specific datasets were identified as having significant relevance to the CFA mapping objectives, data was acquired and necessary conversion and standardization processes were carried out in preparation for conducting a co-occurrence analysis. Where necessary, data were rescaled to New Jersey and reclassified into 30’ grid cells. Inputs were then organized by three environments (terrestrial, freshwater aquatic, and marine) and into five categories (ecological condition, conservation infrastructure, fish and wildlife habitats, biodiversity, and negative influences). For each input, metrics were reviewed by DFW biologists and converted into a standard weighting system which normalized all datasets to address the objectives of the CFA mapping process. Accordingly, weights were assigned following a standardized five tier scale (“5” being the highest value and “1” being the lowest) based upon factors which included (but were not limited to): the relevance of the data layer to our CFA mapping objectives, the degree to which the "regional" datasets addressed habitat values or conditions that were specific to New Jersey, and the original range of the source dataset values. The exception to the positive five tier scale included negative weights that ranged from -10 to -1 and a “restricted” category that excluded an area from being mapped as a CFA regardless of its intersection with one or more resource elements with positive values. Additionally, as the final mapping effort was based upon the “additive mapping” of valued habitats, the proportion to which any one dataset addressed a specific mapping objective needed to be factored in (i.e., if several datasets existed that were correlated with one specific issue, individual dataset weights were reduced to address confounding influences).
Phase 1 Process Summary:
Compiled ~40 inputs spanning terrestrial, freshwater aquatic and marine environments from state and regional sources
Performed conversion, re-scaling and reclassification so that each input was standardized into 30’ cells
Categorized data into five geodatabases: Ecological Condition, Conservation Infrastructure, Fish and Wildlife Habitats, Biodiversity, and Negative Influences
Assigned relative importance (weights) to each input
General GIS Method – Phase 2
Once inputs were reclassified according to assigned weights into 30’ grid cells, a (weighted) co- occurrence analysis was performed that calculated the sum of all inputs. The resultant grid was then stratified by Landscape Region and rescaled by calculating percentile values for each cell relative to every other cell within the region. Cells were reclassified according to percentile ranks. For example, percentile values 0.90-1.00 were classified as the 90th percentile, 0.80-0.89 were classified as the 80th percentile and so forth.
Phase 2 Process Summary:
Performed weighted co-occurrence analysis that combines inputs to identify areas where several different qualities are present (“resource-rich” areas).
Stratified by Landscape Regions (calculated percentile ranks relative to each region) in order to have even distribution of areas between regions
General GIS Method – Phase 3
Areas that represented the top 70 percent of the data within each region were extracted and converted to vector data made up of contiguous polygons. Terrestrial areas smaller than 3.14 acres were removed from the result (there was no size threshold applied to aquatic areas). The remaining polygons served as core areas from which geoprocessing routines were applied to identify key connections (e.g., riparian corridors) and proximate areas within the 50th percentile or above. Identified areas were combined/dissolved with the core areas and generalization routines were run to create protective buffers and smooth boundaries of resultant contiguous polygons. Nature’s Network (<http://naturesnetwork.org/>) data on terrestrial, wetland and aquatic cores developed during the process of creating CFAs was used as a guide to incorporate some additional areas that were not captured in the initial CFA delineation. Lastly, urban areas were erased from the result and a minimum size threshold of
3.14 acres was applied to all contiguous areas.
Phase 3 Process Summary:
Extracted percentile > 70 in each Landscape Region
Applied minimum size criteria to identify core areas
Applied connectivity rules to select key connections between high value areas
Ran basic generalization/simplification processes to provide protective buffers and smooth boundaries of areas
Utilized Nature’s Network (<http://naturesnetwork.org/>) data on terrestrial and aquatic cores as guide to add in areas not captured
Erased all areas coded as “urban” in 2012 land-use/land-cover
Applied minimum size criteria to all contiguous areas
