Bats of Maine: How Terramor is Helping in Conservation Efforts
They emerge at dusk—silent, swift, and often unnoticed. With wings that whisper through the trees and a hunger for mosquitoes, bats are nature’s nighttime ninjas. Although they are often misunderstood, these creatures are doing some serious behind-the-scenes work to keep our ecosystems balanced and our skies bug-free. Maine, and specifically the Acadia region, have historically housed several species of bats, however, we have seen a sharp decline in population in recent years. Which is why we are doing our part to make sure our local ecosystem stays healthy, and these vital nighttime creatures stay abundant.
We admire these incredible mammals—not just for their ecological superpowers, but for the story they’re writing right here on Mount Desert Island and the surrounding areas. It’s a story of resilience and hopeful comeback—and we’re proud to be part of it.
MEET THE BATS
Bats often get a bad rap. They’re seen as eerie, shadowy creatures flitting through the night sky. But the truth is, they play a vital role in keeping our ecosystems in balance. These animals are more than just nighttime fliers—they’re natural pest controllers, pollinators, and quiet contributors to biodiversity. On Mount Desert Island, several species make their home among the trees, including the Little Brown Bat, the frosted Hoary Bat, and the now-threatened Northern Long-Eared Bat. Each one plays a unique role, from managing insect populations to signaling the overall health of the environment. In ways both visible and hidden, bats are helping to keep nature thriving.
THE THREATS THEY FACE
Watching bats sweep silently across the sky at dusk is a magical reminder of the delicate rhythms of nature. But even these familiar evening silhouettes are becoming harder to spot. Across Maine—and right here on Mount Desert Island—bat populations have been shrinking at an alarming rate. In just a few short years, species that were once common have become rare. The reasons behind this decline are complex and deeply concerning: disease, habitat loss, and shifting environmental conditions have all played a role in pushing these vital animals to the edge.
Habitat loss, climate change, and human activity have all contributed to the decline of bat populations—but one of the most devastating threats is White-Nose Syndrome, a fatal fungal disease that disrupts hibernation and often leads to starvation. In response, the National Park Service and other conservation partners across Maine have prioritized bat monitoring and habitat protection, working together to support recovery and safeguard the future of these vital creatures.
CONSERVATION & MONITORING EFFORTS IN MAINE
Since 2011, Acadia has seen a staggering 95% decline in certain bat populations—a number that has sparked deep concern and renewed conservation efforts across the region. The National Park Service has been monitoring bats in the area since the mid-1990s and continues to protect both the species and their critical habitats. In Maine, agencies like the Department of Inland Fisheries and Wildlife, in partnership with the U.S. Fish and Wildlife Service, have taken action as well. One major step included installing a protective gate at the state’s largest bat hibernacula, preventing human disturbance and giving bats a better chance at survival during their most vulnerable season.
TERRAMOR’S SUPPORTING ROLE
At Terramor, we believe that protecting nature starts in our own backyard—quite literally. In recent years, our grounds team has taken thoughtful steps to create a more welcoming environment for bats, helping to support their return to the region.
What We’re Doing:
- Swapping out chemicals for nature-friendly repellents:
We’ve phased out chemical insecticides in favor of natural, herbal alternatives—like garlic, thyme, and other essential oils. These deter pests without harming the insect populations that bats rely on for food.
- Installing eco-conscious bat houses:
We’ve built and placed nine bat houses across the property using recycled wood. Each one can shelter up to 150 Little Brown Bats, offering safe and quiet roosting spots.
Placement matters, and our team carefully follows guidelines to ensure ideal conditions:- East-facing to capture morning warmth
- Mounted 10 feet high on tree bark
- Positioned near water sources and away from foot traffic
- Surrounded by minimal branches to allow easy access
- Creating space for education and connection:
We introduced Bat Chats, a fireside experience where guests can learn more about bats’ role in the ecosystem—and how small actions can support their survival.
A Note of Progress
Since putting these efforts into motion, we’ve noticed more bat activity around the resort—an encouraging sign that these quiet initiatives are making a difference. Statewide, Maine has also seen a slight uptick in bat populations thanks to the collective work of conservation groups, researchers, and individuals. We’re proud to be part of that momentum and committed to continuing our role in welcoming the bats back.
LET’S MAKE IT A COMEBACK
Bats may be small, but their impact on our environment is anything but. Their decline has signaled just how fragile our ecosystems can be—but with care, education, and community action, we have the chance to help them thrive again. By protecting their habitats and shifting our habits, we can be part of a hopeful story: one where the night skies are full once more.
