Japanese Barberry Invasive Control

Virginia

We are looking for 3-5 or more volunteers for multiple dates to help reduce the quantity of the invasive species Japanese Barberry at our Fraser Preserve in Northern Virginia.

  • January 16
  • January 23
  • January 30
  • February 6
  • February 13
  • February 20
  • February 27

(All dates fall on a Wednesday)

Work hours are 10 a.m. — 1 p.m. For more information or to sign up contact volunteer Margaret Chatham at margaret.chatham@verizon.net.

Cancellation will occur in bad weather, but work will continue through drizzles and temperatures above freezing. Contact Margaret no more than an hour before the workday if you are unsure of the workday status at 703-785-8175, call or text.

Volunteers will need to bring their own leather gloves as barberry has sharp thorns. If you have a garden fork or weedwrench and clippers, please bring them. Volunteers will be picking the red berries off this bush, collecting them in bags and digging up the plant.

Volunteers will need to be comfortable working outdoors in the weather in forested field conditions. Bring water and any snacks you’ll need.

Meeting location will vary: either the corner of Allenwood and Springvale, at the gate or at the camp. Margaret will keep you informed of the location.
