On Thursday, April 25 at Stone Zoo, we will be conducting a routine animal escape drill. These drills are an important part of our preparedness training. While the drill is occurring, guests will be asked to move to certain areas within the Zoo for a brief period of time (not to exceed 10 minutes). We will do our best to have minimal impact on the guest experience. We are very dedicated to safety and we appreciate your participation. If you have any questions about what to expect, please do not hesitate to contact us at 617-989-2000 or info@zoonewengland.org.


Boston Area City Nature Challenge

Join the Boston Area City Nature Challenge – a fun competition with cities across the world to document (April 26 - 29th) and identify (April 30 - May 5th) the most species!

Citynaturechallengemap BoxFrom April 26 - 29, 2019 we'll need people (i.e. you) to help us take observations (e.g. taking photos with your phone) of as many species as possible to record nature in and around Boston. All species count! This information will help create a more accurate picture of the Boston area's biodiversity, focusing within the I-495 corridor and out to Stellwagen Bank. Any observation of plants, animals, fungi, even microbes, in the greater Boston area made during these days will count for the challenge. Scroll down for tips and resources on how you can help.

The Boston Area City Nature Challenge (CNC) is a collaborative project. Learn more about our effort.
