Arlington Forestry Arlington Forestry is the Facebook presence of Arlington's urban forestry department, for posts on the latest forestry science, and pictures of great trees.

View terms of use: https://www.arlingtonva.us/terms-conditions/ Arlington has a long history of having incredible trees. With 1200 acres of County parkland, public buildings, Public Schools, regional parkland and the contribution of great growing spaces from the federal property (Parkway, Arlington National Cemetery) we have plenty of opportunity for having great trees. Most of our trees exist on private property, and working with our citizens to maintain the beauty and sustainability of our community is crucial to our program. Arlington Forestry is the Facebook presence of Arlington's urban forestry department. Pictures of interesting trees and tree-related stuff, as well as new programs and documents are posted here. Feel free to ask questions and enjoy the galleries of pictures of champion trees and tree curiosities around the County. The forestry department works on maintaining tree canopy around the county by replanting in public right of way through parks, through the Tree Canopy Fund, managed by Arlingtonians for a Clean Environment, and through outreach and education to Arlington's residents. We work closely with the following groups in helping maintain a healthy forest:

Tree Stewards, a dedicated group providing education for private citizens on tree care and planting in Northern Virginia. http://treestewards.org/

The Arlington master naturalists, who work with us on horticulture and ecological education:

Our invasive plants program, which helps keep our region maintain its unique and native plant composition:

And a very active commission, the Forestry and Natural Resources Commission, which recommends actions to the County Board:

Currently, we are working on updating our Urban Forest Master Plan, through a planning process called the Forestry and Natural Resources Plan. Learn more here:

Announcing the 2026 Urban Tree Summit! 🌳 Join Casey Trees and Montgomery Parks on Wednesday, September 23, in Silver Spring for a full day of sessions on the future of urban forestry.

This year's program covers new tools reshaping how arborists work, what centuries-old trees in the UK can teach us about managing urban forests today, and how greening schoolyards can expand equitable tree canopy in our communities — and much more.

Whether you're an arborist, planner, educator, or just someone who loves trees, there's something here for you. Check out the full agenda and get your ticket at UrbanTreeSummit.org 🎟️

New USDA hardiness zone map released today ‼️ Besides checking to see if your zone has officially changed, there is a lot to explore here! This map includes two new zones and a finer level of detail.

The NEW hardiness zone map is based on 30-year averages (1991 to 2020) for the lowest annual winter temperatures within specified locations. The 2012 edition was based on averages from 1976 to 2005.

Low temperature during the winter is a crucial factor in the survival of plants at specific locations.

New zones: 12 and 13 have been introduced for regions with average annual extreme minimum temperatures above 50 degrees and 60 degrees F, respectively. They appear only on the maps for Hawaii and Puerto Rico.

The new map(s) were jointly developed by Oregon State University's PRISM Climate Group and the USDA's Agricultural Research Service, and it is the most accurate and detailed USDA has ever released.

Hi folks. We have been less active on social media, as we are working hard on the update to the Forestry and Natural Resources Plan. We are currently in drafting mode to address all the amazing comments from residents and interested parties. Keep your eye out for that in the new year.
