About this site

Vernal pools are considered ephemeral wetlands—they are areas that are only flooded during the wetter seasons, normally winter and spring. During summer and fall, most if not all of the standing water will evaporate. 

These dynamic habitats are home to several animal and plant species that rely on the changing conditions to survive and reproduce. For example, some amphibians rely on these small, temporary bodies of water in order to lay their eggs in an environment free from predators such as fish.

About Parker River and Great Bay National Wildlife Refuge

Parker River National Wildlife Refuge is located on Plum Island, a barrier island along the coast of northern Massachusetts. The mix of habitats—including salt marsh, salt pannes, maritime shrubland, and beach dunes—makes the location especially important for migratory birds. One of the main focuses of the Refuge is to restore habitats and ecosystems to be more resilient to climate change, particularly for salt marshes in the Great Marsh.

Great Bay National Wildlife Refuge is oak hickory forest with many forested wetland and tidal estuary tucked inland just west of Portsmouth, New Hampshire. Here, fresh riverine waters meet salty oceanic waters allowing a wide variety of plant and animal life to flourish. The Refuge is another important stopping ground for migrating birds to feed, shelter, and in some cases breed.
