About the Program
The Davey Tree Company's Wetland Studies and Solutions, Inc. (WSSI) office in Gainesville, Virginia, is on a site of about 5 acres in a residential and commercial area about 35 miles southwest of Washington DC. The site includes about 1 acre of woodland along with the developed area surrounding the office building. The wildlife team has drawn on the extensive knowledge among employees about ecosystems to plan and maintain habitat projects that also demonstrate the company's commitment to sustainable, low-impact development.

Practices and Impacts

  • A native planting on a berm along the roadway in front of the site, and in a bed alongside the building, is being maintained and augmented. The berm area is mowed annually to keep it open in the manner of a native Virginia meadow. Additional native species were seeded in 2019, and hand control of invasive lespedeza is ongoing. Monitoring includes annual randomized sampling of vegetation plus one season of insect surveys.
  • A set of nest boxes installed in the past were found to be in habitats no longer suitable for native cavity nesters. They were removed and five new boxes were installed at the edge of the meadow area. The boxes are monitored weekly and so far have been used by house wrens. The team is consulting with the Virginia Bluebird Society on ways to attract more bluebirds. A grassland on adjacent property is a recognized asset to the habitat.
  • In 2006, a 3,626 sq. ft. green roof was installed, designed to support wildlife as well as to manage stormwater and insulate the building. Mostly native species were planted (along with some noninvasive sedum) for pollinators; the plants were chosen with a range of bloom times. The green roof also includes a wetland area and is used as a demonstration of low-impact development practices.
