Old Man’s Beard—Usnea

life_in_maine_usneaUsnea is a generic name for a rather broad group of lichen in the parmeliaceae family. Hanging from dying or sick trees like green cotton, it is mostly called by the common names of Old Man’s Beard or Beard Lichen. Although usnea indicates the symptoms, it is not the cause of the tree’s condition. Usnea is very sensitive to air pollution, especially sulfur dioxide, which can severely impede its growth.

Usnea is believed to have antibiotic properties and was used like a sterile gauze for wounds. It is recommended to only use this plant externally. The lichen can also be used to create dyes for textiles, giving yellow, orange, green, blue, or purple hues. Click on the image for a larger view.

Spring Salt Marsh

morse_mountain_spring_marshWinter eventually gives way to spring. The snow thaws, signaling the start of what is fondly referred to in Maine as mud season. The salt marsh at Bates-Morse Mountain Conservation Area is a tangle of flattened grass. There is not a burst of growth—the plants don’t seem to trust the threat of snow and frosts have gone, and they are right not to. But the air is scented with the season’s potential. Click on the image for a larger view.

Changing Seasons, Part 2

morse_mountain_annual_changeThe salt marshes and dunes at Bates Morse Mountain Conservation Area are always in flux. While we like to think of the season as four monolithic blocks clearly delineating their character to the landscape, the year passes over the land with infinitely variability. No two moments are the same. Click on the image for a larger view.

Changing Seasons, Part 1

morse_mountain_spring_thawSpring just does not simply arrive in Maine; snow and ice don’t simply vanish. Spring comes like a gentle kiss on the land, slowly melting away winter.

This pond in the salt marshes of Bates Morse Mountain Conservation Area is just opening up. In a month or two, fish fry will populate the water. This pool is isolated from the rivers and streams that cut through the marsh, yet the fish population is stable. Amazingly, the salinity of the water is higher than the ocean that feeds the marsh.

Winter Salt Marsh

morse_mountain_winter_marsh_iceSalt marshes are amazing places. Some of the toughest environments exist right between the land and the sea. Places where extreme changes in salinity, temperatures, and water level can be a daily event.  This marsh is on the eastern edge of the Bates-Morse Mountain Conservation Area along the Morse River.
