New Discovery of Rare Bat Species at Merrill Creek Reservoir
In an exciting development for wildlife enthusiasts and conservationists alike, the Eastern small-footed bat has been confirmed at Merrill Creek Reservoir in Warren County, New Jersey. This discovery marks a significant milestone as it is the first documented presence of this rare species within the county’s borders, as announced by the reservoir’s management, the Conserve Wildlife Foundation of New Jersey (CWF), and the New Jersey Division of Fish and Wildlife (NJDFW).
Why This Discovery Matters
The Eastern small-footed bat, slated for potential endangered status in New Jersey, has faced significant threats from diseases like white-nose syndrome, which severely impact bat populations across North America. The species typically thrives in rocky, elevated areas near water sources, but its elusive nature and similar echolocation calls to other bat species have made it challenging for researchers to confirm its presence.
Initial surveys conducted as part of a two-year research initiative pointed to Merrill Creek Reservoir as a suitable habitat. Acoustic surveys in 2024 and 2025 detected sounds indicative of the rare bat, leading to a confirmation through mist-netting in July 2025, where a male bat was successfully captured and examined by biologists.
Implications for Conservation Efforts
Notably, this find expands the Eastern small-footed bat's known range in New Jersey, suggesting that the species may inhabit previously unexplored areas. With the closest known population roughly 30 miles away, this discovery emphasizes the importance of human-modified landscapes like MCR, which can emerge as unexpected havens for biodiversity.
A Bright Future for the Eastern Small-Footed Bat
The collaborative efforts between MCR, CWF, and NJDFW reflect a commitment to preserving New Jersey’s natural heritage. Plans are underway to enhance protective measures for the Eastern small-footed bat, aimed at ensuring its survival in the state.
Get Involved for Wildlife Conservation
For those looking to contribute to bat conservation efforts, local wildlife organizations welcome volunteers and donations. Engaging in conservation initiatives helps safeguard rare species and promotes biodiversity within our ecosystems.
