What We Do

Habitat Protection

One of the greatest threats to biodiversity is habitat loss. In one of the most densely populated states in the country, the refuge staff at Stewart B. McKinney work hard to protect a variety of habitat types in order to conserve foraging, breeding, and resting places for different wildlife species. Each year, we control human disturbance on the refuge by closing sensitive areas to the public, educating visitors about the USFWS mission, and staffing our units with qualified personnel to engage the public and encourage wildlife-dependent recreational activities on refuge lands.

Invasive Species Control

The introduction of non-native flora and fauna has caused extinctions all over the globe. Invasive plant species can disrupt ecosystems by forming monocultures, taking over habitat of rare species, changing fire regimes, and by providing inadequate forage or cover for wildlife species. The refuge staff is busy preparing invasive plant management plans for all units of the refuge. These plans outline current target species for control and/or eradication. Invasive plants are typically controlled using manual, mechanical, and chemical methods. Species that we are concerned about include Japanese knotweed, garlic mustard, mile-a-minute vine, perennial pepperweed, and Japanese stilt grass.

At-risk Species Monitoring

Falkner Island is the largest common tern colony and only roseate tern colony in Connecticut. Terns nest in large groups for protection from both aerial and ground predators. These seabirds lay their eggs on the ground on sand, gravel, or grass. When predators are seen, the whole colony of birds – more than 4000 on Falkner – will fly up and dive at and defecate on the predator. Roseates are federally endangered; there are less than 100 of them left in Connecticut. They nest with the more abundant common tern to protect their eggs/chicks from being eaten by gulls, crows, and herons. Each year staff, interns and volunteers monitor this important bird colony, as well as other animal and plant populations all across the refuge.

Visitor Services

In addition to maintaining and enhancing all the public areas and trails for visitors to enjoy on their own, refuge staff and volunteers frequently offer guided nature walks, kayak tours and educational programs. You can come to one of our pre-scheduled events or - if you're a scout troop, senior group, adventure club or other organization - you can call the visitor services manager and set up a special visit: 860-399-2513 x8134.
