Tools of CHANJ


Connecting Habitat Across New Jersey (CHANJ) is an effort to make our landscape and roadways friendlier to wildlife movement by identifying key areas and actions needed to achieve habitat connectivity across the state. This project is designed to help:

  1. prioritize land protection,
  2. inform habitat restoration and management, and
  3. guide mitigation of road barrier effects on wildlife and their habitats.
CHANJ offers tools and resources to guide these goals forward in a strategic way. Whether on the local or statewide scale, the tools can help land managers, transportation planners, conservation groups, and the general public to visualize their place in New Jersey’s habitat connectivity puzzle and to be more proactive and collaborative in their planning efforts. This can also reduce conflicts between agencies, which saves time and money. The success of CHANJ in fact depends on a variety of user groups and partnerships implementing its guidance.


The CHANJ Mapping is a statewide analysis showing important areas for habitat connectivity across New Jersey. Mapping highlights our remaining intact habitats, called "Cores," and the best opportunities to keep those areas functionally linked via "Corridors." It also identifies road segments that cut through habitats and are likely to pose problems for animal movement. Together, these Cores, Corridors, and Road Segments represent the most advantageous places to focus conservation actions for wildlife connectivity in New Jersey.

The CHANJ Mapping can be accessed a few different ways:

Map thumbnailOption #1: Online Interactive Map
The CHANJ Web Viewer is easy to use from any computer or mobile device. It’s pre-loaded with the CHANJ layers and a variety of supplemental layers, such as municipal and county boundaries, watershed boundaries, water bodies, preserved lands, and several aerial imagery and basemap options. We recommend bookmarking the page or adding it to your device’s Home Screen for ready access in the field. A detailed User Guide and a Quick Guide are available in the Web Viewer’s “About” section.

Option #2: Download the Layers
The CHANJ Cores and Corridors, Stepping Stones, CHANJ Action Regions, and New Jersey’s NAACC Culvert Inventory data layers are available for download through the NJDEP Bureau of GIS CHANJ menu.

Option #3: As Feature Services
From ArcMap Desktop, choose “Add Data From ArcGIS Online” from the “Add Data” drop-down menu and search for the layer by name or its ArcGIS Online Item ID. For more information about each layer and other viewing options, click the associated link in the Feature Services Table (pdf, 155kb).

A complete description of the Mapping – including goals, supplemental layers, and the methodology used to create it – is found in Chapter 2 of the Guidance Document (see below).

Guidance Document

A companion to the CHANJ Mapping, our Guidance Document (pdf, 16mb) offers information and resources to help users make strategic choices about preserving land, restoring habitat, and mitigating the effects of roads on wildlife. Together with the Mapping, the Guidance Document will help steer a landscape strategy that preserves and maintains habitat connectivity for terrestrial wildlife across New Jersey, so that healthy populations can persist long into the future.
