MassWildlife: Five Years of Bat House Monitoring

Print Story | Email Story
December is a season of gratitude—and this year, we're shining a light on MassWildlife's volunteer bat house monitoring program. Thanks to the dedication of 23 volunteers across Massachusetts, all 34 bat houses at 30 sites were monitored regularly during the summer months in 2025 despite mosquitoes, summer storms, and busy schedules. Over the past five years, a total of 53 volunteers have contributed to the program. Seven volunteers have participated every year since the start of the program, providing consistency and invaluable expertise that guides and strengthen the project.
 
Massachusetts is home to nine bat species. Several, including the little brown bat and northern long-eared bat, have suffered steep population declines due to white-nose syndrome, a fungal disease that has devastated bat colonies across North America. Summer roosts are essential for bat survival because they provide females a safe, warm place to raise their pups.
 
Bats roost in natural areas like tree cavities, and in structures like house attics and barns. Bat houses play an important role in conservation by providing alternative summer roosting habitat when other suitable sites aren't available. Properly designed and placed bat houses can support colonies of dozens to hundreds of bats, giving them a secure location to rest during the day. By relieving pressure on human structures, bat houses also help reduce conflicts between people and bats.
 
Results from bat house monitoring are as follows:
  • Year 1: 16 percent occupied, 26 percent showed potential use
  • Year 2: 7 percent occupied, 10 percent showed potential use
  • Year 3: 10 percent occupied, 23 percent showed potential use
  • Year 4: 6 percent occupied, 15 percent showed potential use
  • Year 5: 15 percent occupied, 9 percent showed potential use
Although bats can take several years to adopt artificial roosts, the signs of activity we see each summer are promising. Bat house occupancy varies, which is expected since bats naturally rotate between multiple roosts. These results show steady signs of bat activity and a strong likelihood that the houses will continue to be used in the future.
 
Volunteer bat house monitoring efforts are helping MassWildlife understand species distribution and abundance in Massachusetts, which bat house designs and placements are most successful, and how bat populations respond to changes in habitat availability. Every observation helps build a clearer picture of bat ecology in our state, informing both research and conservation strategies. Thanks again to all of our volunteers for your dedication to bat conservation.

Lanesborough Looks to Dissolve Baker Hill road DIstrict

By Breanna SteeleiBerkshires Staff

LANESBOROUGH, Mass. — The Select Board is looking to move forward with dissolving the Baker Hill Road District, which is hindering the Berkshire Mall sale.

On Friday, the Select Board heard from Vice Chair Juli Baker and Chair Deborah Maynard on how Tuesday negotiations went with Cypress Equities, JMJ Holdings, town counsel, the town administrator, and state Rep. John Barrett III. 

Baker said that during Tuesday's meeting, everyone agreed the goal was to have a successful sale of the mall for redevelopment as it’s in the best interest of the town.

Baker said Barrett assured them the state is willing to take the Connector Road and that the state is willing to provide grants to the town to renovate the water and srwer infrastructure, with an estimated total of $4.5 million, to facilitate the property's redevelopment.

"We have received assurances from Representative Barrett that the commonwealth will provide the monies and will take the Connector," Baker said.

While buyer Cypress Equities saw some benefit in keeping the district, ot now doesn't since the state is willing to provide the funds and renovate the infrastructure, according to Baker. 

Baker said that in the meeting, Cypress Equities prefers to enter into a tax increment financing (TIF) and will add to the agreement an amount of funding for public safety services, which would have come from the district. She said Cypress said it would rather enter into one agreement with the town than two agreements with the town and the district.

Mall owner JMJ Holdings is willing to pay $350,000 to the town upon closing, Baker said. 

The meeting Friday was to consider moving forward with a dissolution of the district.

"But the decision that it hinges on tonight is whether to move forward to the dissolution of the Baker Hill Road District in some manner," she said.

Baker said she has worked long and hard to see if there was another alternative to this, working closely with the district which has been "very cooperative and very helpful" in making changes.

The district had agreed to make changes to its governance and taxation; agreeing to have a cap for Cypress as well as agreeing to work to have the state take over the road, sending letters of support.

"What changed this for me is that I've always said it's important to have the special district because we get the public safety funding, and it's also important for the economic district to bring the features that an economic district brings because of what we're up against with the infrastructure problems, and the change at this point is that we have a buyer who is willing to supply that public safety money and commit to it over time, along with the TIF that the town would do, which is essential," she said.

"At this point, I feel like it's in the best interest of the town and protects the town the best in terms of a future where we can develop a mall and bring that economic benefit in. You definitely need to reduce taxes, and you cannot do that without a fully developed retail operation right there. So it's been, you know, deeply difficult decision making," Baker said.

Board members Jason Breault and Jeffery Walters agreed it was the best decision to move forward.
