Help us locate bats and monitor bat-favored habitat.

The Northeast is the most severely affected region in the U.S. for bat population decline, already exceeding 70 percent. Scientists have documented a 99% loss of northern long-eared bats and expect the little brown bat to disappear from the region within the next 20 years. Managing for the forest types supportive of bats may save them.

Did you know?

  • Out of 1,200 species of bats worldwide, only 9 species of bats live in Massachusetts
  • Little brown bats live an average of 40 years
  • Bats give birth to only one pup a year, making them highly susceptible to extinction
  • Bats use echolocation to determine the size and distance of objects
  • Bats are friendly creatures that purr when petted and are beneficial too – a single little brown bat can eat 1,000 mosquitoes per hour!
