CCLT participates in a state-wide scientific study of Big Night.

In late March or early April, we hear the vocalizations of spring peepers resonating from thawing vernal pools, where their lives began and where they return to start a new generation. CCLT’s Frog Pond and Salamander Swamp, along Range Road in Cumberland, is a popular spot to observe many species of frogs and salamanders as they make their annual migration from woods to water, where they mate and lay their eggs.

We are all scientists!

CCLT collects important data for the statewide Maine Big Night project and are thrilled to have your help. We count each species we see, how many injured, dead, or alive, and also the number of vehicles that pass through. The collected data tracking frog and salamander migration informs solutions to protect their populations. Lead volunteers are on site for you to report your findings. Many families or pods work together for a fun group activity and to not over-report sightings.

In order to better protect these vulnerable critters, ensure participants’ safety, and collect the most accurate data possible, we are limiting the number of registrants. So, if you’re interested, be sure to sign up now! Please read the training manual below if you are a new volunteer.
