As members of associations concerned with the
environment and the health of green spaces in the Boston areas, your help is
extremely precious and appreciated in building awareness about Black Swallow
Public lands such as Fresh
Pond Reservoir suddenly are infested with it, causing real concern. And the
place where the plant has established itself spectacularly in the last
few years is in our very gardens in semi-urban areas. It now has an
extensive seed bank that will keep germinating for years to come, even if we
were to stop new seeds from being generated. This is abetted by the
difficulty of identifying it when it is very small. I am enclosing pictures of
the plant at many different stages, so that it can be detected as soon as it
flies in on the wind, lands, and germinates.
Once there, because the plant's stem is
extremely brittle, it must be dug out carefully as the roots have nodes that
will generate new plants. The bigger the plant, the more thorough the digging
out of the root system must be. If the plant reaches maturity, the seed
pods must be removed before they ripen. All materials
must be disposed of in the regular trash so they will be buried in landfill. If
we include them in the yard waste bins, they will infect the local compost
centers. The use of chemicals such as Round-Up
Concentrate is somewhat effective at undiluted strength.
Spreading awareness works one person at a time.
Thanks for your great work as wardens of our
