he pin oak is located behind the sidewalk at 409 N. Thomas Street, a short distance northwest of the north corner of 4th Street North and North Thomas Street (see  https://www.google.com/maps/place/409+N+Thomas+St,+Arlington,+VA+22203/@38.8742419,-77.1109904,840m/data=!3m1!1e3!4m5!3m4!1s0x89b7b4221a340db5:0x8923595bcd7ff1d9!8m2!3d38.8742377!4d-77.1088017.) The tree is on the property of the AHC (Arlington Housing Corporation).  The County’s photograph of the tree is at: https://arlingtonva.s3.dualstack.us-east-1.amazonaws.com/wp-content/uploads/sites/13/2017/04/409-N-Thomas-St-Pin-Oak.jpg.

The southern red oak is located near the street entrance of 317 N. Thomas Street, on the northwest side of N. Thomas Street, midway between Pershing Drive and 4th Street North. (see https://www.bing.com/maps?osid=a2258b70-3a76-4a4b-8f25-2b621a087e44&cp=38.873667~-77.109164&lvl=17&style=h&imgid=5813799e-9670-4aee-aeb8-ec26da55b406&v=2&sV=2&form=S00027).

Both of the trees are within the County’s Buckingham Historic District and are on the property of the AHC (Arlington Housing Corporation).  They were probably planted in the late 1930’s during the initial development of the Buckingham Community.  Both trees are therefore probably more than 80 years old.

Little is known about maximum ages that pin oaks and southern red oaks can attain. Pin oaks averaged 138 years of age in an old-growth stand in Kentucky. A southern red oak in Virginia was estimated to be approximately 151 years old.  For information about pin oaks, see:  https://plants.usda.gov/factsheet/pdf/fs_qupa2.pdf.  For information about southern red oaks, see http://dendro.cnre.vt.edu/dendrology/syllabus/factsheet.cfm?ID=68.

These are the Buckingham neighborhood’s first notable trees. The pin oak is only the second of its species in Arlington that has received a plaque.
