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.

Fenton: Governor's Council Must Deliver for the Berkshires

Community submissionGuest Column
I am a Springfield lawyer running for Governor's Council and I am asking for Berkshire County residents to support me over an incumbent from North Adams. 
 
Here's why: Last year I learned about staffing issues in our regional courts that I could not ignore. In 2025, it was reported that four of Western Massachusetts' 11 Superior Court judgeships were vacant, all at the same time. A few weeks later, that grew to five vacancies. This meant there were only six Superior Court judges serving all of Western Mass at a time when Berkshire, Hampshire, Franklin, and Hampden counties had more than 100 pending homicide cases. 
 
Those numbers were alarming to me, so I started to engage with leaders in the community who work most closely with the court system and I came to learn that these vacancies were only the tip of the iceberg here in Berkshire County.
 
I learned that no Superior Court or District Court judge had been appointed from the Berkshires since the current incumbent took office. As a result, there is not a single Superior Court judge who lives in the Berkshires today, and several of the District Court judges drive in from other counties to support Berkshire courts in Pittsfield, Great Barrington, and North Adams. Court staff also informed me about severe staffing shortages at the Berkshire Clerk of Courts office resulting in other counties needing to loan staff to the Berkshires just so hardworking employees can take a brief and planned summer vacation. This is not normal. These issues are a reflection of genuine problems with the Berkshire County court system and show a lack of proactive attention from our Governor's Councilor.
 
Instead of focusing on regional equity, I watched as the current incumbent celebrated that she has voted against the governor's nominees more than any other councilor, without much explanation as to why. Most recently, she voted against two extremely qualified former prosecutors for the Parole Board. This was despite an in-person plea from the governor and a letter of support from all the three of the district attorney's from Western Mass. Those votes do not show independence or standing up for principles, they demonstrate naivete, and an unwillingness to work with the key stakeholders.
 
I had seen and heard enough. I decided to jump in the race and challenge the incumbent to address these problems head-on.
 
I am a partner of a regional law firm. I understand our courts and the importance of having qualified, fair and hardworking judges. And I know how important it is to have judges from the Berkshires serving the Berkshires. To achieve that, you need strong relationships with the legal community and local stakeholders. You need to know how to use the power of the Governor's Council to fight forcefully for our region. And you need to be laser focused on identifying vacancies before they occur so that they can be filled quickly with local candidates.
