Eastern Tiger Swallowtail We planted more than 50 trees and shrubs this last spring and the wildlife garden is taking shape. We can't wait for spring!

Now we need to keep up the good work. Planting is a tough job, but all is easily lost without long-term maintenance. Please join us for a morning of weeding, pruning, watering, and wildlife watching.

PWC LandfillSpeaker, Tom Smith, Prince William County Public Works, Solid Waste Division Chief.

Prince William County is working to transform the Landfill into a community resource for producing green energy, recovering valuable material and providing opportunities for research and education. The Eco Park will focus on the three E's -- Environment (Sustainability and Environmental Protection), Energy (Renewable Technologies) and Education (STEM and Ecology).

The goal of the Eco-Park is to educate the public on the importance of ecological sustainability, how we can protect the environment and exceed requirements in a cost effective manner.

A tour of the Landfill Eco-Park will be held on Saturday, June 6, 2015 at 10:00am as a follow up to the conversation. For more info and to RSVP (seating is limited to 40), email or call 703.490-5200.

Walking Tour: Past, Present, and Future of Downtown Manassas

When: Saturday, July 11, 10-11:30am

Where: Manassas VRE Station, 9451 West Street, Manassas 20110

RSVP: alliance@, 703.499.4954

City of ManassasTour Leader: Charlie Grymes, PWCA Chair

Since the 1850’s, the development of homes and businesses at Manassas has been based on transportation. A train depot still services passengers, and the city is at risk of evolving into a walkable community. The defunct Journal-Messenger newspaper building and a nearby carwash are morphing into new housing, as the city invested in “streetscaping” and festivals to develop an arts and entertainment district.

This walking tour will examine the history of the downtown, changing patterns of transportation and land use, and what’s next as elected officials propose expanding VRE/Amtrak and a new bypass on Godwin Road to divert commuter traffic.

Bird Walks at Merrimac Farm

When: The last Sunday of every month, beginning at 8:00am.

Where: Merrimac Farm, Stone House, 15020 Deepwood Lane

Volunteer - 2015 Bluebird Trails Open for Business Soon!

When: Sunday, March 29, 2:00 to 3:30am

Where: Meet in front of Chinn Library entrance

RSVP appreciated. Call PWCA at 703-499-4954 or email alliance@

Thanks to the many people who install and tend nesting boxes, Bluebird populations are growing. We need volunteers to help monitor the Bluebird Trails at Merrimac Farm, Chinn Park, and Veteran's Park.

Volunteers make sure all is well, address problems as needed, and record information about activity in each of the nesting boxes included in the Chinn Park Bluebird Trail. Volunteers follow a protocol to ensure birds nesting in the boxes are not disturbed.

This is a great activity for families. It takes about 90 minutes to cover an entire trail... unless you notice interesting things along the way and stop to take a closer look! There's nothing quite like seeing newborn Bluebirds grow from hatchling to fledgling.

The best time to plant a tree was 20 years ago. The second best time is today.
