Please note: This schedule is subject to revision. For the most recent scheduling, contact us at or (703) 764-4830.

Logistics: Unless heavy rain is forecast or an update indicates otherwise, you can assume that we will be out. Bring work gloves, if you have them, and a bottle of drinking water. Unless otherwise noted, we will provide tools. Wear sturdy shoes to our field events. Please do not wear sandals or open-toed shoes! And if you are coming out to one of our field sites, such as Meadowood, you're better off wearing long light-weight pants, rather than shorts. (But shorts are fine at the nursery.) And if you're new to our work, it's best to confirm before you come. You can confirm by contacting Lisa. (See the previous paragraph.)

If you live in the DC area and would like to get involved in conservation, we want to hear from you. We could really use your help, and you could make a big difference to the remaining natural places of this region. We work with over 600 volunteers every year, and these people are crucial to just about everything that we do in the DC area.

If your company is looking for employee volunteer venues, or outdoor team-building activities, please get in touch with us. We have experience working with large numbers of people in the field, and we would be happy to help you plan an event that will benefit local parkland.

Field Schedule for Winter

If you're lost, please call Lisa on her cell, at 571-213-8025.

Every Sunday in February, at Marie Butler Leven Preserve, from 10 am to 1 pm. We will be out removing invasives at Marie Butler Leven Preserve every Sunday in February. Work will be cancelled if we experience inclement weather or below freezing temperatures (i.e. rain, snow, or below 36 degrees). Please wear study boots (rubber boots are best) and bring a bottle of water. If you can help it, please try not to bring a disposable plastic water bottle..

-Directions to the Native Arboretum: The Marie Butler Leven Preserve is in McLean, Virginia. The street address is 1501 Kirby Road. (See the ADC Northern Virginia Map Book, map 5526, square G2.) If you’re coming from the Beltway, exit on Route 66 East; from 66, take the first exit, to Leesburg Pike (Route 7); turn left on Leesburg Pike, then almost immediately after the underpass, turn right onto Idylwood Road (695). Just stay on Idylwood, which becomes Kirby Road after the intersection with Great Falls Street. Stay on Kirby; once you have passed the stop sign at Chesterbrook Road, the Preserve is about half a mile up on the right. View the Preserve's location on Google Maps.
