Garlic Mustard Challenge!
Muster up for Garlic Mustard

2020 – The 12th Annual Garlic Mustard Challenge

This spring there will be several opportunities to get the family outside for a day of fun! The Garlic Mustard Challenge is back! The GMC is a series of events that seeks to provide your family with a day of free, outdoor fun while working to protect the beautiful public lands that we all love. Removing garlic mustard helps to protect our native forests, wildflowers, and wildlife.

Garlic Mustard is a particularly nasty, non-native invasive species that thrives in partial shade and has no trouble growing in forest understories. Garlic mustard can quickly take over an area crowding out our native plants including trillium, jack-in-the-pulpit, ramps, and our beautiful, often vulnerable, native orchids. Garlic mustard even produces chemicals that can keep our native plants from being able to grow!

Garlic mustard makes it tough for two rare butterfly species to survive. The mustard white butterfly and the West Virginia white butterfly sometimes mistakenly lay their eggs on garlic mustard instead of their native host plants. The results are disastrous, the eggs hatch, but the caterpillars die before they can form a chrysalis.

We need an army of volunteers to help get rid of this invasive species! Please join us for the 2020 Garlic Mustard Challenge and together we can help stop the spread of one of the most invasive species found in our state. Get a group of friends and join one of our organized pulls. See our Calendar of Events for a full list of our pulls. If you need any information please contact Hannah Wroton at

The Garlic Mustard Challenge is brought to you by the Monongahela National Forest, Appalachian Forest National Heritage Area, and the Potomac Highlands Cooperative Weed and Pest Management Area.

Join us for this year’s challenge. Together, we can all muster up the courage to defeat Garlic Mustard!
