Bald Eagles Again Calling the Arboretum Home

For the first time in almost 70 years, the bald eagle is nesting at the National Arboretum. Absent from all of the District of Columbia until 2000, the bald eagle’s last known nest site in the city was on the top of the Arboretum’s Mount Hamilton. Remarkably, the current pair selected a site very similar to the one described in 1947 as “on a hill near Bladensburg Road” with “a magnificent view of the city of Washington.” Read about when the eagles were first noticed, what the Arboretum is doing to protect them, and where there are restrictions on pedestrian and vehicular travel on the grounds.

Professional Arborists Brave "Arctic Blast" to Train at the Arboretum  

On February 16th, more than fifty arborists arrived at the U.S. National Arboretum for a day of hands-on professional training with certified arborists and certified tree care safety professionals. The concurrent sessions covered rigging and crane removal of large trees and beginner climbing skills. The rigging and crane session was filled to capacity, with an indoor safety discussion and question and answer session followed by hands-on instruction removing a large white oak with a 75-ton crane. The climbing skills session started inside with a safety and equipment check, then moved outside where the five trainers gave individual climbing instruction to groups of three to five students, including one session given in Spanish.

Despite temperatures in the teens, attendees were enthusiastic. When asked about the cold, one participant said, “If I weren’t here, I would still be out working in this weather.” The National Arboretum thanks all of the dedicated trainers for their willingness to instruct under such daunting conditions and all of the attendees who came to increase their knowledge and skills.
