Crown vetch: just discovered at Pleasant Valley Conservancy

Today I spotted a small patch of violet-flowered plants on the lower part of our south-facing slope. We soon ID'd it as crown vetch, a ghastly invasive plant that we have never had at Pleasant Valley Conservancy. By noon we had destroyed it with Garlon 4. We'll be monitoring the site for any residual growth, and will be keeping an eye out for any new patches. I've seen what crown vetch can do to other prairie remnants in our area. We won't let this happen here! How did it get here? We'll probably never know.
