McLean and Great Falls residents can claim up to two free native trees, delivered to their front doors, through an expanded Fairfax County giveaway.

The county's Urban and Community Forestry Division (UCFD), partnering with the Arbor Day Foundation, opened the program countywide after initially reserving trees for neighborhoods ranked high or very high on the federal Social Vulnerability Index. That priority window began in August. The remaining trees are now available to any county resident while supplies last.

The March round of the same program was claimed within hours, FFXnow reported. Residents who want trees this time should not wait.

Each household can receive up to two one-gallon trees chosen from non-invasive, regionally native species suited to Northern Virginia. After signing up, residents get access to an online tool that identifies the best planting spot on their property and estimates how each tree could affect home energy costs. Trees ship directly to the resident's address with shelters and stakes included.

Brian Keightley, director of the UCFD, has called the program a way for residents to take "meaningful climate action right in their own yards." At the county's April 24 Arbor Day celebration, Keightley said the urban forest is one of Fairfax County's strongest tools for cooling neighborhoods, managing stormwater and expanding wildlife habitat.

Fairfax County has about 55% tree canopy cover and aims to reach 60% by 2030, according to a county announcement in March. The free-tree program targets that gap by putting saplings in private yards, where the county says they will add shade, reduce energy use, improve water quality and lower urban heat island effects.

No closing date has been announced. The county describes the supply simply as limited.

Residents with accessibility needs can call the UCFD at 703-324-1770 (TTY 711) for information in alternate formats.

A separate county program distributes free trees to community organizations for planting on private property. The application deadline for that program is Friday, Oct. 30.
