WESTON - Nearly a dozen volunteers braved the rain this morning to tackle two invasive plant species that are threatening southwestern Connecticut.

Volunteers from the Aspetuck Land Trust spent the morning searching for Garlic Mustard and Japanese Barberry at the LeGallienne Bird Sanctuary in Weston.

Both plant species were brought to Connecticut long ago and now threaten to choke out native plants and animals.

Garlic Mustard can be pulled like a weed, but the Barberry needs to be cut down with a saw and burned.

Organizers say a wet day like today actually helps their efforts.

Lisa Brodie, of the Aspetuck Land Trust, says, "It's easier to pull the Garlic Mustard when it's wet. And when we're using our flame weeding equipment it's best used under wet conditions so we don't risk the chance of a fire."

Experts say you also have to burn both plants once they are dead because the seeds can live for up to four years.
