Overview
Habitat fragmentation caused by residential and commercial development is one of the greatest threats to Cape Cod’s native wildlife. In response, The Compact produced the Cape Cod Wildlife Conservation Project—a groundbreaking regional study designed to bring conservation biology and landscape ecology directly into land acquisition decisions.
By mapping 32 distinct habitat types across 160,000 acres (61% of the Cape’s land area) and evaluating nearly 30,000 individual real estate parcels, this initiative provides a scientific roadmap for land trusts, municipal land bank committees, and conservation organizations across Barnstable County to safeguard the region’s natural diversity.
The Cape’s Six Core: Ecological Systems
Our analysis revealed that the vast majority of the Cape’s highest-ranking wildlife habitats are concentrated within six massive "core" conservation complexes:
-
Massachusetts Military Reservation (Upper Cape)
-
Sandy Neck / Chase Garden Creek Complex (Barnstable & Yarmouth)
-
Punkhorn Parklands (Brewster)
-
Nickerson State Park (Brewster & Orleans)
-
Monomoy National Wildlife Refuge (Chatham)
-
Cape Cod National Seashore (Outer Cape)
Additional High-Priority Habitats
Other vital regional systems identified for active acquisition and protection include Bournedale (Bourne), the Town Neck Beach & Marsh System (Sandwich), Quivet Neck / Crowe’s Pasture (Dennis & Brewster), Namskaket Creek (Brewster & Orleans), and Herring River / Boat Meadow Creek (Eastham).
Critical Habitats & Rare Species
The project mapped habitat requirements for more than 400 species expected or known to occur in Barnstable County, highlighting key community types:
-
Forested Woodlands (104,368 Acres): Accounting for 60% of all mapped habitat, mixed pitch pine-oak woodlands support the highest potential number of breeding species (134 species) on Cape Cod.
-
Grasslands, Heathlands & Wooded Swamps: Grasslands and heathlands support 52 breeding species, while wooded swamps support 45 species.
-
Rare & Vulnerable Ecosystems: Sandplain grasslands, coastal heathlands, and pitch pine/scrub oak barrens account for just 2% of the Cape's remaining land area due to historical fire suppression and development. Protecting these sites—along with coastal plain pondshores, vernal pools, and barrier dunes—is essential to saving state-listed Endangered, Threatened, and Special Concern species.
Parcel Evaluation & Land Trust Priorities
To translate scientific mapping into actionable real estate acquisition, the study ranked 29,213 individual parcels (totaling 138,451 acres) based on parcel size, ecological value, surrounding land context, and percent upland.
| Maximum | 1,633 | 42,763 | 86% |
| High | 11,388 | 61,591 | 48% |
| Medium | 13,382 | 31,174 | 16% |
| Low | 2,810 | 2,923 | 8% |
| Total | 29,213 | 138,451 | 52% |
The Path Forward: Conservation Strategy
While the Cape has successfully protected 86% of its highest-ranked (Maximum) acreage, roughly 66,467 acres of identified wildlife habitat remain unprotected.
With an average parcel size of under 5 acres, large single-owner tracts are increasingly rare. The Compact’s strategic focus centers on:
-
Targeting Unprotected Priority Towns: Prioritizing acquisition outreach in towns holding 70% of the remaining unprotected "Maximum" rank parcels—specifically Mashpee (1,412 acres), Harwich (883 acres), Bourne (743 acres), Falmouth (640 acres), and Barnstable (458 acres).
-
Buffer & Corridor Assembly: Leveraging parcels ranked as "High" and "Medium" that abut existing open spaces to expand conservation boundaries and link isolated habitats.
-
Active Habitat Management & Restoration: Enhancing protected public lands and land trust properties to maximize conditions for wildlife, particularly through active restoration of rare grassland and heathland habitats.
