Invasive Plant Control Volunteer Workdays


The Nature Conservancy is looking for 3-4 volunteers for multiple dates to help reduce the quantity of the invasive species Multiflora Rose (and maybe some Japanese Barberry, Linden Viburnum and Autumn Olive) at our Fraser Preserve in Northern Virginia.

  • January 6
  • January 13
  • January 20
  • January 27
  • February 3
  • February 10
  • February 17
  • February 24

Work hours are 10 a.m. - 1 p.m. For more information and to sign up contact, volunteer Margaret Chatham at

Volunteers will need to bring their own leather gloves as barberry and multiflora rose have 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 should be comfortable working outdoors in the weather in forested field conditions. Bring water and any snacks you’ll need. Meet at the gate/small parking area by the main kiosk.

Volunteers must read and sign our COVID field guidelines and health screening questions. Guidelines include having a mask readily accessible if working less than 6' apart, bringing hand sanitizer and confirming you have health insurance.

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 (don’t try voicemail).
