Twenty-two years ago, biologists could find only 55 Blanding's turtles left in one Massachusetts wetland. Today there are more than 300 — and fourth-graders helped raise many of them in their own classrooms.

  • 55 adult Blanding's turtles counted at Great Meadows in 2003
  • 300+ turtles now estimated at the same refuge
  • 40 Massachusetts elementary schools raising hatchlings each year
  • 800+ headstarted turtles released since the program began in 2003

From Quarter-Sized to Quarter-Pounder

Blanding's turtles are globally endangered, and Massachusetts has no idea exactly how many remain in the wild — only that the number keeps shrinking in most places. At Great Meadows National Wildlife Refuge in Concord, too many nests were being dug up by predators, and the few hatchlings that survived were getting picked off before they ever grew big enough to defend themselves.

So Zoo New England started a "headstart" program in 2003. Hatchlings barely bigger than a quarter are handed to local classrooms and nature centers, where kids raise them for nine months before release. The extra months of safe feeding make a dramatic difference.

"By the time they've gone through that head-starting process, we've taken a quarter-sized turtle and we've grown it to be about the size of — I always say — a quarter-pounder cheeseburger is the goal," said Emilie Wilder, Zoo New England's Associate Director of Conservation Engagement. That extra bulk makes the turtles far too tough for most predators to bother with.

A Turtle Named Small Fry Comes Full Circle

This year's release carried extra weight. Three nests at Great Meadows were built by turtles who had themselves been headstarted as hatchlings — proof the program is now sustaining a second generation in the wild. One of those mothers, a 16-year-old nicknamed Small Fry, was headstarted years earlier at the Alcott School in Concord.

"There's a repeated truism that for Blanding's turtles to persist, you need vast, unbroken landscapes that are really hard to find in Massachusetts," said Mike Jones, state herpetologist for MassWildlife. "The Zoo New England team has shown it's possible to muster a network of unconventional partners to help this species persist in relatively developed areas."

When Wilder visited Small Fry's old classroom to share the news, the fourth-graders didn't need convincing. Of the ten turtle species native to Massachusetts, six are considered rare or endangered — a fact Wilder shares with every class before asking if they want to help. The answer, according to GBH News, is always a unanimous cheer.

Why Community Science Works Here

Blanding's turtles are highly mobile, often traveling more than a mile from wetlands to find nesting sites — frequently landing in backyards, office parks, and schoolyards. That overlap with people could be a liability. Instead, the program turned it into an advantage: neighbors who know a turtle nest is nearby are far less likely to let it get disturbed, run over, or illegally collected.

Great Meadows isn't an isolated success. Partners including the U.S. Fish and Wildlife Service, the Town of Concord, and the Concord Land Conservation Trust have helped replicate the model at other Massachusetts sites, with more than 2,000 students now involved statewide and over 1,400 turtles released.

In protected wetlands like Great Meadows, Blanding's turtles can live 80 years or longer. The hatchlings released this year, raised by hands barely bigger than their shells, may still be nesting there when today's fourth-graders have grandchildren of their own.
