Signs of Spring – Vernal Pools

Vernal pools are teeming with life each and every spring…that is, until they disappear!

A vernal pool is a depression in the earth that pools with water each winter and spring from rain and snow melt and dries out during the warm summer months.

Because this “pond” dries out each year, it doesn’t host creatures like fish, which makes it an excellent home to breeding amphibians, as well as macroinvertebrates and other creatures. An absence of fish means eggs, tadpoles, and larvae have a better chance of survival.

Some creatures found in vernal pools include frogs, salamanders, fairy shrimp (very small – and cute! – crustaceans), as well as larvae for insects like dragonflies and mayflies.

DNRT is proud to have 12 certified vernal pools on our properties. Three of these are trailside (and you might be able to spot egg masses from the shore)! The vernal pools at Parsons Reserve, Smith Farm, and Destruction Brook Woods are easily visible. We are in the process of certifying four additional pools and are always exploring our reserves for undetected vernal pools. The certification process requires individuals to monitor an area for the presence of certain species and habitat. Certifying a pool essentially registers it with the state’s Natural Heritage and Endangered Species Program. Having this certification provides an additional layer of protection for this important habitat. Curious about certifying a pool? Learn more here: vernalpool.org/macert-1

Not only does DNRT protect vernal pools, but also the distance around the vernal pool, the vernal pool envelope. Many amphibians that are hatched in vernal pools live in the area around the vernal pool.  The vernal pool at Parsons Reserve was right on our property line, and we are pleased to state that last year we were able to protect the other half of the vernal pool and area surrounding it. Be sure to check out the pool on your visit to the daffodil field!

Be on the lookout and be careful driving during this important breeding season! Some salamanders will travel up to ¼ mile to get to their breeding ground. That’s long distance for those tiny feet! This mean amphibians may be crossing the road. Watch for frogs and salamanders!
