How many rattlesnakes are in Massachusetts? The species is considered to be endangered, leading state officials to propose "Rattlesnake Island." But questions from the public and lawmakers have caused a slowdown in the proposal's timeline.
BOSTON - The proposal to increase the population of venomous timber rattlesnakes in Massachusetts by dropping them on an island in the Quabbin Reservoir sparked a local uproar and led to an apology from top environmental officials.
Speaking with reporters in the State House earlier this month, Senate President Stanley Rosenberg, D-Amherst, said a lack of transparency about the proposal led to the public's concern, and noted that rattlesnakes, considered to be an endangered species, had been placed in two other locations in Massachusetts, in a "much quieter way."
Was there a prequel to "Rattlesnake Island"? Not quite.
There are five isolated populations of rattlesnakes in Massachusetts. They are located in three areas: the Berkshires, the Blue Hills and the Connecticut River Valley.
There are a total of 200 rattlesnakes in the state, according to a spokeswoman for the Executive Office of Energy and Environmental Affairs.
Rattlesnakes born in the wild, on Mount Tom and the Blue Hills, are regularly captured, raised in captivity to increase their chances of survival, and then released back into their respective birth areas.
And those five current populations -- and how they're handled -- are very different from what state environmental officials proposed for the Quabbin Reservoir island known as Mount Zion.
The Mount Zion proposal is unique, creating a brand new population on the island, which is closed to the public. It's has never been tried before with timber rattlesnakes, according to the Executive Office of Energy and Environmental Affairs.
But state environmental officials have made a similar effort to revive populations of the northern red-bellied, cooter, the diamondback terrapin, the wood turtle, the eastern box turtle and the eastern spadefoot toad.
To help boost the rattlesnake population, state officials had proposed "headstarting" young snakes at the Roger Williams Zoo in Rhode Island, allowing them to grow up enough to survive against natural predators, and then placing them on Mount Zion.
"Releases of young snakes [are] expected to be in the range of only one to ten in any given year. In the southern Appalachians, a healthy rattlesnake population may be as high as 150 individuals, however here in Massachusetts, our populations are generally much smaller," the state's website on the proposal says.
A top environmental official recently apologized for the rollout of the proposal and said a working group will review the timeline and location for the proposal.

The working group will help decide what happens next.
"At the end of that process, if there is a conclusion amongst the legislative delegation and the local officials and the general public that this is not in the best interest of the biodiversity of the local region, then we would consider making a change in course of action," Energy and Environmental Affairs Secretary Matthew Beaton said, according to the State House News Service.
