More than 440,000 people made their selection in the Vote for America’s National Tree, hosted by the Arbor Day Foundation between Jan. 1 and National Arbor Day 2001. The oak was the favorite, winning 101,000 votes, with the redwood earning second place, with nearly 81,000 votes.

In Fairfax County a battle is being fought to keep non-native plants from taking over the parks. Without any natural checks on their growth, invading plants can quickly crowd out indigenous plants needed by native wildlife. County parks can be preserved by following these general guidelines:

*Yard waste: Do not dispose of yard waste on parkland. Non-native plant seeds in the waste can spread. Learn to “grasscycle,” a practice that improves your lawn and keeps your parks safe;

*Plant disposal: Remains of invasive plants should be put in Fairfax County trash to be burned at the I-95 Waste-to-Energy Facility. Seeds and plants in landfills may still grow;

*Native plants: Use native plants for your grounds and garden.

Especially invasive species include Tree-of-Heaven, Orientalo Bittersweet, Purple Loosestrife, English ivy, Japanese stilt grass and Japanese honeysuckle.

For complete listing of invasive plants or information on native species, call Green Spring Garden Park at 703-642-5173. Information on yard waste and grasscycling, call Fairfax County at 703-324-5052.
