A new tree disease has been detected in Fairfax County, threatening one of the region’s most common trees.
County officials have confirmed, in the fall, they found that a number of American beech trees in three parks in Fairfax County were infected with beech leaf disease (BLD). The parks include Burke Lake Park, Hemlock Overlook Park near Clifton, and Fairfax Station’s Fountainhead Park.
The disease causes the leaves of beech tree saplings to develop dark green stripes in the veins as well as potentially puckered, cupped, or distorted leaves. In more mature trees, it can result in reduced foliage.
It can be fatal to the trees, causing them to possibly die within six to 10 years.
BLD is somewhat mysterious, in that officials and researchers at the county’s Urban Forest Management Division (UFMD) are still trying to figure out exactly how it spreads. There is also no cure.
“Good tree care, including proper mulching and watering during droughts, may be helpful,” the county’s Department of Public Works and Environmental Services (DPWES) said in a press release. “There is ongoing research underway to learn more about BLD and how to effectively treat it.”
The disease doesn’t affect humans, animals, other tree species, or yard plants. It hasn’t been detected anywhere else in the county at the moment besides the three noted parks, DPWES spokesperson Sharon North confirmed to FFXnow.
The county is asking any residents who spot a tree they believe might be infected to report it to email@example.com with photos of the tree or by calling 703-324-1770 TTY 711.
“Reporting potential infestations will allow UFMD to quickly begin monitoring BLD and providing treatment once it is developed.”
BLD was first detected in Ohio about a decade ago, and Virginia’s first case was found in Prince William County in August 2021. What has officials so concerned is how poorly the disease is understood and the impact it could have on already-dwindling regional forests.
It remains unclear how BLD spreads. Experts are looking into several possibilities, including possible transmission through bacteria, fungi, mites, or even microscopic parasitic worms.
Additionally, the American beech tree makes up about 10% of the county’s forests. Any mass loss of the trees could permanently change the region’s landscape.
“Given the American beech tree comprises a large portion of our eastern trees, the disease can potentially alter the composition of the eastern forest,” DPWES said. “It is one of the most common local giant trees.”
Burke Lake’s marina is being closed for a number of months, and the lake will be lowered by two feet to help stabilize the beach area and improve drainage.
The $1.5 million project aims to stabilize the beach area as well as add “armoring” — the use of physical structures to prevent further coastal erosion — to a large portion of the shoreline. Drainage will also be improved around the existing boathouse and restroom buildings.
“Gravel from the shoreline has eroded and deposited in the shallow area where [Fairfax County Park Authority] boats are launched, creating challenges when launching boats and causing damage to the boats,” spokesperson Judy Pedersen told FFXnow. “In addition, existing storm outfall and foot traffic are causing erosion to the shoreline adjacent to the marina.”
Paid for by county voter-approved bonds, construction is expected to start next month. The marina is already closed until the spring.
“Contingent on the weather, the marina is expected to reopen at the end of April 2023,” the park authority says on the project page.
To help with the construction, Burke Lake is now in the process of being lowered by two feet.
A “controlled drawdown” is underway, with 2 to 4 inches of water being pumped out of the lake a day. It’s estimated that Burke Lake will hit the 2-foot goal “on or before” next Monday (Nov. 19), based on a predicted lack of rainfall over the next several days.
The lake is expected to remain at this lower level until at least the end of March 2023, but its normal elevation will eventually return through natural runoff.
The rate and timing of the lake level’s rise is “contingent on precipitation,” the project page notes.
While the marina will be closed and water levels will be lower than usual, Burke Lake will remain open to those looking to fish and spend time on the water.
However, the park authority is asking boaters, canoeists, and kayakers to proceed with caution since “numerous obstructions will be exposed or may be present just under the water’s surface.”
The 218-acre public fishing lake is owned by the Virginia Department of Wildlife Resources. The lake is located in Burke Lake Park, which is owned and operated by FCPA.
The park sits on land originally purchased by the federal government as a potential site for an international airport. When airport plans shifted to Chantilly, the nearly 900 acres of land were handed over to the county. The park opened to the public just about six decades ago, in 1963.
