- 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: Kittatinny Ridge CFA
- Enumerated_Domain_Value_Definition:
-
The Kittatinny Ridge CFA features significant topography and ridgeline associated with the Appalachian Mountains, vast mature contiguous forests, and small to medium sized watersheds of remarkable water quality. Topography and geologic aspect have created a variety of unique habitats such as talus slopes and bare rock outcrop found nowhere else in the state, and the westerly slopes and lower elevations extending to the Delaware River contribute distinctive habitats including seeps, limestone fens, and hemlock ravines. Much of the Kittatinny Ridge is protected state and federal land. While the Flatbrook and other watercourses of medium drainage areas provide abundant aquatic resources, numerous additional watercourses of extremely small drainage areas flow directly to the Delaware River and support salamander assemblages found nowhere else in the state. Forest management that focuses on eliminating invasive plants and creating a habitat mosaic while retaining older forest stands could improve diversity in mid- and lower elevation habitats and benefit rare species.
The ridgetop features xeric communities such as pitch pine and chestnut oak that are generally of high quality and consist mostly of native vegetation. The ridgetop’s harsher conditions (e.g., wind exposure and thin soils) stunt some plant communities, creating a mosaic of habitats and species diversity. These communities could be in jeopardy due to fire suppression, as without fire they will be replaced by oak forest over time. Such a shift would shade out currently sun-exposed areas that are critical to rare reptiles and barren ground- nesting birds, and cause vegetative changes that could alter food resources for wildlife. The westerly slopes and lower elevations have been greatly impacted by the agriculture of early settlers, leaving behind nutrient poor soil with a plethora of invasive plants; however, these areas still include a diverse suite of habitats, including hemlock forests, springs, fens, ravines, and ephemeral wetlands, important to a variety of wildlife.
This CFA encompasses 7% of the Skylands Landscape Region at 36,446 hectares including 34,600 hectares of terrestrial habitats and 1,846 hectares of aquatic habitats.

- Enumerated_Domain_Value: Kittatinny Slope Mosaic CFA
- Enumerated_Domain_Value_Definition:
-
The Kittatinny Slope Mosaic CFA showcases broad forest patches mixed with agriculture and grasslands in the shadow of the Kittatinny Ridge. The CFA is the bridge between the Kittatinny Valley Mosaic CFA and the Kittatinny Ridge CFA with distinctive geology and management needs. Bobcats travel along the slopes, and the bottomlands include the key Paulins Kill drainage tributaries that feature one of the most significant populations of a federally listed mussel species in the state along with wood turtles and trout streams. The higher elevations of the slopes feature xeric communities such as pitch pine and chestnut oak while the lower elevations are more representative of the overall Skylands Regional Landscape.
Fire suppression has been and continues to alter the mid- and higher elevation vegetation over time, converting the landscape to an oak forest that shades out the slopes and alters the thermal characteristics critical for rare reptiles and barren ground-nesting birds.
This CFA encompasses 3% of the Skylands Landscape Region at 15,700 hectares including 14,715 hectares of terrestrial habitats and 985 hectares of aquatic habitats.

- Enumerated_Domain_Value: Kittatinny Valley Mosaic CFA
- Enumerated_Domain_Value_Definition:
-
The Kittatinny Valley Mosaic CFA supports many of the remaining undeveloped natural communities that are home to some of the state’s rarest terrestrial wildlife, such as the bog turtle. The value of this CFA is not only in what remains, but in its potential to link the largely protected Kittatinny Ridge and Highlands Core CFAs. The valley is characterized by expansive agriculture and grasslands among rolling forested hillsides and distinctive groundwater fed wetland complexes. The valley contains a mosaic of habitats ranging from small forest tracts to scrub-shrub habitats and agricultural grasslands.
Habitat conditions within the valley are representative of the overall Skylands Regional Landscape. While the wildlife habitat within this area is not considered poor quality, as a patchwork of natural lands among a more human-modified landscape, this area would benefit from restored connectivity to best provide live-in and corridor habitats for wildlife.
Increasing forest management and broad restoration of inactive agricultural lands could increase overall biodiversity in this CFA.
This CFA encompasses 3% of the Skylands Landscape Region at 17,050 hectares including 16,107 hectares of terrestrial habitats and 943 hectares of aquatic habitats.

- Enumerated_Domain_Value: Wallkill Headwaters Wetlands CFA
- Enumerated_Domain_Value_Definition:
-
The Wallkill Wetlands CFA is primarily protected federal and state land featuring lower gradient floodplain wetlands and connecting uplands between New Jersey’s portion of the lower Wallkill River Valley and Vernon Valley. These areas represent the largest intact river floodplains in the northern part of the state and are valuable for migrating passerines and resident species like Indiana bats, bronze copper butterflies, wood turtles, and blue-spotted salamanders. Breeding grassland birds and raptors thrive here as well. This majority lowland wetland CFA is also a key bridge to the more mountainous, adjacent Highlands Core CFA.
Habitats within this CFA are generally of good to moderate quality, although management of invasive plants and maintaining or increasing native plant community diversity along riparian floodplains would strengthen the overall resilience of this CFA. Portions of the critically important wetlands, invaded by non-native plants, within this CFA have unique restoration needs compared to those within the larger region and such restoration would benefit aquatic and semi-aquatic species. Agricultural practices threaten habitats and wildlife by contributing sediment, phosphorus, and fecal coliform to waterways.
This CFA encompasses 1% of the Skylands Landscape Region at 5,451 hectares including 5,272 hectares of terrestrial habitats and 179 hectares of aquatic habitats.

-
- Enumerated_Domain_Value: Highlands Core CFA
- Enumerated_Domain_Value_Definition:
-
The Highlands Core CFA is composed of mostly protected contiguous high elevation forest. Timber rattlesnakes, bobcats, barred owls, and red-shouldered hawks all depend on these lands to sustain their populations. These are also key recovery areas for golden-winged warblers and other declining songbirds. A large portion of the Highlands Preservation Area is within the boundary of this CFA.
The habitats and conditions in this CFA are similar to those described for the Skylands Regional Landscape. They are generally of high quality but have fewer invasive plants than are found in the lower elevations of the Kittatinny Ridge CFA. However, diversifying forest age class and reducing forest-floor invasive plants would help secure wildlife populations and support colonization by additional animal species.
This CFA encompasses 14% of the Skylands Landscape Region at 75,140 hectares including 69,626 hectares of terrestrial habitats and 5,515 hectares of aquatic habitats.

- Enumerated_Domain_Value: Glacial Lake Passaic Wetlands CFA
- Enumerated_Domain_Value_Definition:
-
The Glacial Lake Passaic Wetland CFA features bottomland hardwood floodplain complexes that remain in good condition. These wetlands are all within the Passaic River watershed and include vernal pool complexes that support blue-spotted salamander populations. There are few remaining undeveloped areas in this region.
Invasive plants and a lack of forest management imperil the persistence of wildlife diversity within this CFA. As such, habitat management including the treatment of invasive plants and selective forest management would greatly benefit the species diversity. In addition, streambank and riparian restoration may be beneficial in more flood-prone sections to reduce stream siltation and channelization.
This CFA encompasses 2% of the Skylands Landscape Region at 9,655 hectares including 9,309 hectares of terrestrial habitats and 346 hectares of aquatic habitats.

- Enumerated_Domain_Value_Definition:
-
The Raritan and Passaic River Headwaters CFA includes important aquatic areas in the North Branch Raritan River, South Branch Raritan River, and Passaic River watersheds. The Passaic River headwaters were included with the North and South Branches of the Raritan River in this CFA to distinguish the Passaic headwater areas from the lower gradient, floodplain dominated Glacial Lake Passaic Wetlands CFA. Both the Passaic headwaters and the expansive North and South Branch Raritan River headwaters feature moderate gradient streams of high water quality, narrow floodplains mixed with agriculture, and wooded hillsides.
The conditions within this CFA vary by area and watershed. Agricultural practices in headwater regions threaten aquatic habitats and wildlife by increasing sediment, phosphorus, and fecal coliform in waterways, and the lack of riparian buffers contributes to erosion and water quality degradation. Aquatic, semi-aquatic, and riparian species and their habitats are also threatened by point and nonpoint source pollution and flooding that erodes banks and scours stream bottoms. Streambank and riparian restoration may be beneficial in more flood- prone sections to reduce stream siltation and channelization.
This CFA encompasses 5% of the Skylands Landscape Region at 27,191 hectares including 24,829 hectares of terrestrial habitats and 2,362 hectares of aquatic habitats.

- Enumerated_Domain_Value: Northern Delaware River Tributaries CFA
- Enumerated_Domain_Value_Definition:
-
The Northern Delaware River Tributaries CFA highlights predominantly aquatic and riparian corridors of the Musconetcong River, Pequest River, and Paulins Kill watersheds from their headwaters to confluences with the Delaware River. These watercourses feature extremely large drainage basins with broad floodplains that are often closely associated with agriculture. The CFA captures both aquatic areas and undeveloped buffer uplands. Dwarf wedgemussels, triangle floaters, longtail salamanders, and wood turtles are dispersed throughout these basins.
The conditions within this CFA vary by area and watershed. The Category 1 classification of many stream stretches indicates that these waterways are of high quality. There are dams scattered throughout the waterways, and much effort has been expended on dam removal projects (particularly along the Musconetcong River) to enhance fish migration, improve water quality, and help to eliminate flood hazards. Aquatic, semi-aquatic, and riparian species and their habitats are also threatened by point and nonpoint source pollution and flooding that erodes banks and scours stream bottoms. Streambank and riparian restoration may be beneficial in more flood-prone sections to reduce stream siltation and channelization.
This CFA encompasses 4% of the Skylands Landscape Region at 24,115 hectares including 22,430 hectares of terrestrial habitats and 1,683 hectares of aquatic habitats.

- Enumerated_Domain_Value: Hunterdon Plateau Delaware Valley Streams CFA
- Enumerated_Domain_Value_Definition:
-
The Hunterdon Plateau Delaware Valley Streams CFA is focused on aquatic areas that largely consist of small drainages and moderate gradient streams that drain directly to the Delaware River. In otherwise highly developed areas, these riparian corridors often represent the best dispersal pathways for local wildlife. Longtail salamanders inhabit stretches of streams while breeding bobolinks, eastern meadowlarks, and grasshopper sparrows are present in adjacent grasslands.
The habitat conditions within this CFA vary by area and watershed. Much of the area is designated Category 1, indicating that these waterways are of high quality. Changing land use practices, the loss of stream buffers, and the addition of impervious surfaces continue to impact natural habitats and wildlife by increasing the likelihood of point and nonpoint source pollution into waterways. Also, flooding from extreme storms could erode banks and scour stream bottoms. The spread of the highly invasive Chinese pond mussels remains a serious threat to native freshwater mussels in Wickecheoke Creek and tributaries, and possibly the Delaware River.
This CFA encompasses 1% of the Skylands Landscape Region at 7,633 hectares including 6,480 hectares of terrestrial habitats and 1,152 hectares of aquatic habitats.

- Enumerated_Domain_Value_Definition:
-
The Picatinny Military Installation CFA lies within the Highlands physiographic region. It is characterized by the bedrock features of Green Pond Mountain and includes Lake Denmark and Picatinny Lake. This federally managed military installation is home to rare reptiles, raptors, and songbirds, with bobcats also traversing the elevated terrain. Containing nearly 6,000 acres of ridgeline, slopes, and valley floor, approximately 70% of the installation is forested with only 19% developed.
Although much of the natural landscape is used for military training and ordinance testing, the habitats within this CFA are generally healthy forests that are largely protected from outside commercial and residential development. Habitat restoration for federal species is a management priority and restricted access to the installation protects against illegal intrusion by vehicles and wildlife poachers. However, as with many areas within New Jersey, diversifying forest age class and eliminating forest floor invasive plant species would help secure wildlife populations and support colonization by additional animal species.
This CFA encompasses 0.2% of the Skylands Landscape Region at 1,357 hectares including 1,201 hectares of terrestrial habitats and 156 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
