Rare species encountered at the Reserve have included bald eagles, least terns, peregrine falcons, piping plovers, slender blue flag iris, and arethusa orchid.
Below this was a swamp surrounded by a luxuriant growth of asters of every hue, and white and pink spirea and golden rod, and blue iris, and the delicate, rose-colored arethusa, and the blue fringed gentian abounded on every hand; also shrubs of the bayberry, wild rose and sweet brier, with many beautiful ferns.
When June comes, -- when the clethra is heaped with its bee-beloved blossoms, and the grass is green and bright as never again in the year, then the arethusa is to be sought.
But with June comes the most exquisite of our New England wild-flowers, the arethusa, or swamp-pink, as it is often styled, to the great confusion of its delicate, high-born nature with the great, vulgar, flaunting azalea.
