Habitat Inventory & Assessment

We work with partners to identify, inventory, and assess the status of coastal habitats and their living resources.  This information helps us prioritize our work and helps guide decion makers.  Examples of this work are:

gap analysis

Gap Analasis Project for Maryland, Delaware, and New Jersey

The goal of Gap Analysis is to keep common species common by identifying those species and plant communities that are not adequately represented on existing conservation lands. By identifying their habitats, Gap Analysis gives land managers, planners, scientists, and policy makers the information they need to make better-informed decisions when identifying priority areas for conservation.
