Revitalizing Nature: Habitat Restoration Efforts at Odiorne Point State Park

Nestled along the scenic coast of New Hampshire, Odiorne Point State Park is known for its diverse ecosystems and historical significance. The Department of Natural and Cultural Resources (DNCR) working in partnership with Rockingham County Conservation District (RCCD) have taken proactive steps in habitat restoration and coastal resiliency planning. These efforts  have led to trail modifications and closures within the Park to enhance visitor experiences, and allow delicate native plant and animal communities to recover and thrive. Habitat restoration in Odiorne Point State Park is not just about conservation—it’s about ensuring that future generations can continue to enjoy the Park’s unique beauty and biodiversity. By understanding and supporting these initiatives, visitors can play a crucial role in safeguarding the ecological health of this unique landscape.

Increasing human and ecological pressure on Odiorne Point State Park’s dune ecosystems has led to the necessary closure of two trail segments along the Little Harbor shoreline. Foot traffic compacts sand and damages native plants, weakening the dunes’ natural structure. Invasive species like bittersweet and beach rose outcompete native vegetation and disrupt sand movement. Meanwhile, rising seas and stronger storms accelerate erosion. Closing these trails is essential to help the dunes recover and to continue protecting both wildlife and our coastline. 

What You Need to Know About Changes to the Park’s Trails

As part of our dune restoration efforts, two segments of trail through the dunes along the Little Harbor shoreline in the Park will close starting in June 2025 (see map below). During this time, fencing will be installed to clearly mark the closed areas and protect sensitive dune habitats. Access along the coastal trail from the boat launch to Frost Point will depend on the tides. At low tide, the trail will remain passable as a continuous route by shifting onto the beach area. 

However, at high tide, visitors will need to follow an inland detour. To support this shift, two new trails will be created to provide safe inland and beach access, allowing visitors to continue enjoying the coastline while helping to preserve the dunes. There will also be new signage placed throughout the area to guide visitors to the appropriate access points based on tide conditions. A map highlighting the trail closures is currently being prepared and will be released to the public once completed. We appreciate your cooperation and understanding as we work to restore and preserve these critical coastal ecosystems. 

Why Dunes Matter

Sand dunes are far more than just scenic features along our coastline. They are vital, dynamic systems that serve both ecological and protective functions. Dunes act as natural barriers, absorbing the impact of storm surges and preventing flooding and erosion. Dunes also help stabilize beaches by storing and redistributing sand, which maintains the shoreline over time. 

In New Hampshire, dune systems provide essential habitat for native species, including the federally threatened piping plover (Charadrius melodus) and the state-endangered least tern (Sternula antillarum). These shorebirds nest directly on sandy beaches and depend on quiet, undisturbed areas to successfully breed and raise their young. Additionally, dunes support native plants like American beachgrass (Ammophila breviligulata), a crucial species that stabilizes the sand and contributes to the growth and resilience of the dune system.
