Probably you are discouraged by the severe drought we are having in the northeast. It’s hard on our yards and gardens, and especia

lly hard on wildlife, which need extra water put out at our bird feeders to survive. But there is one very big upside of the drought from my point of view. I have found two plants that I have been looking for since 1994. I have recently rediscovered two plants first described in 1911 by the highly respected Westford botanist, Miss Emily Fletcher. Emily Fletcher was known about town as the lady who hiked up her long skirts and tramped through the fields and wetlands in search of rare plants. Women were not at that time invited to be members of the New England Botanical Club, so when she had an identification question, she sent her plants to men who were members. Her letters were often published in the club’s publication, “Rhodora”. All of her 630 pressed specimens, most from Westford, were donated to the Gray Herbarium at Harvard University at her death in 1923.

Emily Fletcher reported in a 1911 entry to the “Rhodora” that she had found “a rare grass, Juncus pelocarpus, which occurs only on the bottom of the middle of Grassy Pond when it is dry”. She also reported Rhexia virginica also known as Virginia meadowbeauty. When I read this report in 1984, I hadn’t realized that Grassy Pond ever dried up. Since then, I have found that the pond does almost dry up occasionally, and therefore is classified as a vernal pool. In the 22 years in which I have been searching for this plant, however, Grassy Pond was never dry in the middle. This year, eureka! The pond is completely dry and one can walk right out to the middle. We walked out there recently and found a plant that looked a lot like Juncus pelocarpus as illustrated in my Gleason and Cronquist  Manual of Vascular Plants of Northeastern United States and Adjacent Canada. I took multiple photos and sent them to Arthur Haines of the New England Wildflower Society. Mr. Haines, who is the author of Flora Novae Angliae confirmed that the plant is, indeed, Juncus pelocarpus. He told me that it is actually a rush, not a grass, and that it is also known as Brown-fruited Rush. He said that it is not on the state list of rare plants, but is uncommon, due to the fact that it only grows in seasonal wetlands. The also uncommon Virginia Meadowbeauty is much easier to identify, and my Peterson’s Field Guide to Wildflowers was all I needed for that. Its a beautiful, startlingly bright pink mass of flowers blooming at Grassy Pond’s margin.

Emily Fletcher was an important contributor to the publication Flora of Middlesex County. At the time of her death at the age of 78, she was movingly recognized by members of the Botanical Club. You can find out more about Emily Fletcher by reading companion papers titled “Emily Frances Fletcher” written by Jean Downy and Marian Harman in 1994. It is available at the Fletcher Library.

After twenty-two years of searching, I am delighted to find that these plants have survived at least 105 years at Grassy Pond, and are now appearing again to have their day in the sun. I like to think that Emily Fletcher would be delighted to see that they are still flourishing. Go see them before the fall rains cover them again! read more…

How are the birds doing in North America?

To answer that question, the North American Bird Conservation Initiative, a consortium of forty conservation organizations and government agencies has just published an important new document titled “The State of North America’s Birds”. More than 350 species of our migratory birds, such as the gray catbird, Baltimore oriole, and the wood thrush pass between Canada, the United States, and Mexico. The report combined citizen science bird data, collected on platforms such as e-Bird, to come up with the 2016 status report on the birds of all three countries, a total of 1,154 species.

The reports’ findings are alarming. It placed 37% of North American birds on a Watch List for Species in Urgent Need of Conservation. For some habitats birds are even more imperiled.  For instance, 57% of ocean birds are on the Watch List. Birds of tropical forests, coasts, arid lands and grasslands are also in steep decline. For these habitats, up to 56% of bird species are in decline. In other habitats, such as temperate forests, tundra, wetlands, and boreal forests, up to 27% of bird species are on the Watch List. Westford is a temperate forest habitat, but our migratory birds spend the winter in the tropical forest.  read more….


Grassy Pond

Grassy Pond is interesting right now because the water level is so low, and it really is “grassy”.

The low water level is probably caused by all the sunny days with little rain in recent weeks.  It is said that Grassy Pond becomes entirely without water about once every 10 years.

By the way, Grassy Pond develops a chorus of frogs on summer evenings, particularly when it’s rainy.  Here’s a recording I made on such a night, focusing on a barred owl.  The owl is interesting, but the background of tree frogs, green frogs, and loud bull frogs is interesting too.
