Arlington currently has Specimen Trees on private and public property, which received the designation through the County’s Trees and Shrubs Ordinance. Specimen Trees are protected from removal or injury. You can nominate your own tree for special protection under this ordinance at the following link:
Special Tree Protection Nomination Form(PDF, 85KB)
Specimen trees will be nominated once a year. The due date for specimen tree applications is September 30. You will hear by October 31 of that year whether your application will be sent to the County Board for review. Applications received after that date will be reviewed by foresters for the next year.
Applications may be rejected before the review date, if insufficient information is provided, or approval from the owner(s) of the tree is not obtained.
1. White oak (Quercus alba) in the front yard of 4836 30th Street North. Property owners Dr. Thomas Cochran and Carol Cochran nominated their neighborhood’s signature tree for its outstanding size.

2. Baldcypress (Taxodium distichum) in front of Our Lady Queen of Peace Church at 2700 19th Street South. This baldcypress was a tree planted in honor of the late Clarence Edward Brown. Mr. Brown was one of the 16 African American Catholic founders of the parish that began this Arlington faith community with the Spiritan Fathers on Pentecost Sunday, May 20, 1945. He lived a couple of blocks from the church and was very active in the parish and in the Nauck community. More information can be found here

1. Tuliptree (Liriodendron tulipifera) on the grounds of Fort C.F. Smith Park. Currently the largest tree measured in Arlington County, this yellow-poplar is almost 21 feet in circumference and 140 feet tall. It is likely one of few trees at historic Fort C.F. Smith Park to pre-date the Civil War.

2. Swamp chestnut oak (Quercus michauxii) in Nina Park. Swamp chestnut oaks are rare in Arlington due to habitat destruction. This specimen is the current County Champion for the species, and it grows in a small urban park area that once supported a large expanse of wooded wetlands and swamp forests.

3. Two Virginia pines (Pinus viginiana) in Lacey Woods Park. Growing within 20 feet of each other, these two pines are the largest and second largest on State record. At an estimated 85 and 100 years of age, they probably date from a time period when farms in the area were abandoned.

4. Scarlet oak (Quercus coccinea) in Chestnut Hills Park. Tied as the second largest scarlet oak in the State, this tree grows in a small neighborhood park that appears to have been part of a historic homestead.

5. Blackgum (Nyssa sylvatica) at Dittmar Rd and 38th Street North. Designated for its size.

6. White oak (Quercus alba) In front of 5618 16th Street North. The county champion white oak, and also the most interesting white oak. Growing out of what appears to be no soil, in the middle of the street, this tree has held on very well for its restrictions. Cabled and braced in early 2014 to prevent failure.
