Most natural communities support a great variety of native plants and animals. Such biodiversity is threatened when a few plant species take over and dominate the herbaceous, shrub, and canopy layers of a forest.

Weed Warrior 15th anniversary badgeThis Week in the Woods

Weed Warriors are out in the parks every day. Here we share some of our latest finds.

  • November 25- Frosts are here and snow is in the forecast, but garlic mustard and celandine are visisble under the downed leaves. If you're looking for flowers, look for witch hazels with their spidery yellow blooms.

Meet the Weed Warriors

In this 15th year of the Weed Warriors, we'd like to take the time to introduce 15 of our volunteers. Our volunteers are people just like you, working to make a difference.

Dave Brooks and others
Weed Warrior Dave

That's Dave in the hat. There are a few other awesome Weed Warriors in that picture too, but Dave's a powerhouse. One recent volunteer description was that he does the work of 10 people. And he does. I was working with him, turned my back for a minute and he cleared a field! You'll find Dave on the first Wednesday of the month working along the Capital Crescent Trail. Or in any of a number of other places, lending his abilities to any project that needs a hand. (The plant in the picture is some very dead oriental bittersweet).

First Saturday Workday

Saturday, December 6, 10:00AM- 12:00NOON
The Long Branch Stream Valley has been invaded by vines! English ivy is taking over the trees. We'll meet at Long Branch - Wayne Park and head out from there. This project is suitable for families, but please no one under 16 without a parent/guardian as we will be using tools. RSVP by December 4 to

Saturday, January 3, 1:00-3:00PM
Ring in the new year with a service project. Location is weather dependent - if the ground is thawed we'll tackle some barberry and if the ground is frozen we'll move onto freeing trees from vines. That's the good thing about invasive plants, there is always something to work on. Stay tuned, or RSVP by December 30 to to get details.

On the 15s

Monday, December 15, 11:00-12:30PM
This final (sniff! sniff!) event of our 15th year celebrations will be a tour of the incredible Northwest Branch led by Carole. This event is open to Certified Weed Warriors and their guest. Reservations required, please RSVP by December 12 to

Weed warrior video imageWeed Warriors on County Cable Montgomery

Some our favorite Weed Warriors did a video interview for "Did You Know?", a local cable show for County Cable Montgomery. If you ever wanted to know what we do, and why, watching this will get you up to speed.

Thank You!
