ACT NOW TO PREVENT INVASIVE SPECIES
Right now, in the tall grass covering Cambria’s many hills, prickly invasive, non-native thistles are growing.
The two worst kinds are the Italian thistle and the Canadian (or milk) thistle.
A good example of out-of-control milk thistle can be seen in the eucalyptus grove off Cornwall in West Village. (This thistle is not the variety eaten by butterflies.) Some thistles are already topped with their purple flowers that, when fertilized by bees, will create seeds that will spread the contagion.
Now is the time to act. This thistle can be killed by any broadleaf herbicide or, if you are against herbicides, wait until the flower has been fertilized and closed and then weed whack it before the seeds mature. Not only are the thistles of this plant nasty, but when fully grown (to 4 feet tall) and dead, they create a highly dangerous fire situation. Each flower creates thousands of seeds, and they spread rapidly with our on-shore winds.
None of us wants to infect our neighbors. Nancy Moure, Cambria
