Planning the Future for Eastern Massasauga Rattlesnakes
In addition to searching for massasaugas in the cattails and mud puddles of southwest Michigan recently, the Eastern Massasauga Rattlesnake Species Survival Plan® (SSP) committee that coordinates zoo management of the species also held their annual population planning meeting.
Yes, it’s just like it sounds—the group of zoo representatives recommending which snakes are paired and which get to breed. While there are 23 zoos who are members of the SSP, not all zoos can participate in the breeding program because only 28 of the snakes are old enough to breed (but not so old they can’t breed). Of the 14 pairs the SSP recommended for breeding, three are at Lincoln Park Zoo, a leader in the program.
Because of eastern massasauga rattlesnakes’ slow reproductive biology (pairs breed one summer and give birth the next summer) we might not have any good news to share for another year. The breeding pairs are in a special breeding facility off exhibit, but visitors can see a 7-year-old male massasauga when they come to Regenstein Small Mammal-Reptile House. Look closely—like his peers in the wild, he can be tough to spot!
Increasing Conservation and Understanding
One of the largest zoo-based conservation and science programs in the country, Lincoln Park Zoo’s Conservation & Science Department is dedicated to improving animal management and wildlife conservation. Zoo scientists combine expertise in a range of disciplines to identify threats to zoo and wild populations and develop strategies to ensure their continued existence.
