The Heron Trail
Layers of the forest
The Salt Marsh
The Salt Marsh is an extremely rich environment that supports thick expanses of salt grasses. In the eighteenth century, salt hay harvested from the marsh was used as mulch for fields. The hay, adapted to a high-salt environment, did not sprout in agricultural fields where the salt content was low.
Plant Life to Anticipate
Animals to Admire
Listen for choruses of croaking Green Frogs and Bullfrogs. These animals use camouflage to hide from their predators. Watch as the Great Blue Heron spreads its wings in descent to the marsh, where it will stalk its prey. Search for the great Moose, with high, humped shoulders, and broad antlers. Twilight is the best time to search for these huge animals as they charge into the marsh to escape droves of relentless mosquitoes.
Plant Life to Anticipate
As you walk along the edge of the Salt Marsh, you will see several examples of salt grasses. Cordgrass grows a few feet tall and has inch-long flower spikes branching alternately from the stalk. Look for the dark-green Blackgrass, a wiry-stemmed rush with tiny, blackish flowers. Observe the clumps of Glasswort, a plant that grows a foot tall with cylindrical, jointed stems, and scaly leaves.
The Grassy Meadow
he last stretch of the Salt Marsh Trail follows the edge of an expansive grassy meadow. This area is home to a variety of wildflowers, insects and birds.
Listen for the buzzing of Honey Bees as they visit flowers in the meadow. Try to identify the many species of butterflies – such as the Tiger Swallowtails with pale yellow wings and black markings, or the beautiful Monarch. If you look closely, you may find caterpillars crawling along the undersides of leaves.
As you approach the Sea Captain’s House, you will hear the waves crashing on the beach and smell the salty air blowing in from the ocean. A walk along the seashore will introduce you to a whole different world of organisms.
“The more he [General Cobb] thought about it, the less ditching seemed to be the answer to the problem of the marshes, and he ended by having a series of dykes built to dam out the sea. Almost a hundred acres were thus reclaimed from the tides, and as the salt hay gradually died out on this drier land, the earth was plowed and seed of the best English hay was sown. The land was rich, and a valuable property was developed. In time, when it became clear that the dykes were practical and would hold against the sea, storage barns were built on the marshes, and the area came to be known by the name it carries today, the Dyke Marsh.”
- Louise Dickinson Rich, The Peninsula
What is it gilds the trees and clouds,
And paints the heavens so gay,
But yonder fast-abiding light
With its unchanging ray?
Lo, when the sun streams through the wood,
Upon a winter’s morn,
Where’er his silent beams intrude,
The murky night is gone.
How could the patient pine have known
The morning breeze would come,
Or humble flowers anticipate
The insect’s noonday hum—
Till the new light with morning cheer
From far streamed through the aisles,
And nimbly told the forest trees
For many stretching miles?
- Henry David Thoreau,
The Inward Morning
