Marching Towards Spring!

Days are getting longer and spring is rounding the corner. Our dedicated team of Mashomack bluebird volunteers have cleaned out the meadow’s nestboxes and birds are beginning to scope out the prime locations. Long known as the heralds of spring, bluebirds are a welcome sight in our meadow. Bring a pair of binoculars and head out to the Yellow Trail the next time you’re at the preserve to catch a glimpse of the happy nesting pairs.

Conserving Fresh Water for Life on Earth

Freshwater systems are in trouble. Deforestation, fragmentation from dams, unsustainable farming and fishing, and unchecked pollution are only adding to the increasingly frequent and damaging impacts of climate change.  But with a new approach, we can change the course for the better. Freshwater systems that are degraded can recover—and they can recover quickly. Where freshwater ecosystems remain healthy and connected, we can protect them.
