The phytoplankton in turn supports a profusion of marine life including fish and sea birds.<\/p>\n\n\n\n
Vernal pools and the creatures that inhabit them are the upwellings of the forest. The flow of nutrients they receive is in the form of the frogs and salamanders that return to them each spring in order to mate and lay eggs. These amphibians and their offspring are, in turn, food for a wide variety of forest creatures including turtles, snakes, ducks, herons, foxes, skunks, and raccoons. Like upwellings in the ocean but on a much smaller scale, vernal pools are nutrient powerhouses of the local food web.<\/p>\n\n\n\n
Species that commonly inhabit Maine\u2019s vernal pools include wood frogs, spotted salamanders, and fairy shrimp. For these creatures, the fact that vernal pools are by definition temporary is a deal-maker. In fact, without vernal pools, these creatures cannot successfully reproduce. The reason for this is that their eggs are gobbled up by fish, if fish are present. So a key to the survival of these creatures is laying their eggs in waters that do not have fish. Pretty smart, huh?<\/p>\n\n\n\n

Their solution is to have a short life span — and to lay hardy eggs that can survive heat, cold, and dry conditions until the pool fills up the next spring. How do fairy shrimp populations come to inhabit a pool far from others and high up on a hillside, one might ask? Turns out that the same ducks that feed on the adult shrimp inadvertently transfer shrimp eggs from one pool to another via their webbed feet.<\/p>\n\n\n\n
Want to see some vernal pools yourself? In this part of Maine, May is the perfect time of year to check for egg masses of frogs and salamanders. The town land at Basin Pond has five vernal pools that can be accessed off the Basin Pond Trail system<\/a>. Hiking the trails and visiting the pools can be done in just a couple of hours and makes a great family trip. Maps and additional resources are below. <\/p>\n\n\n\n

In early spring, as the snow melts and the earth thaws, the hearts of tiny frogs and salamanders who have lain in the earth over the winter also thaw and start beating. As these creatures warm up and start moving, they begin to pilgrimage toward the small seasonal pools where they themselves hatched in a … Continue reading Vernal Pools — Don’t Blink or you’ll Miss ’em!<\/span>
