Roosevelt Island near Rosslyn is closed today due to tree damage from insects and today’s impending storms.

The National Park Service made the announcement this morning.

The park service says numerous trees have been severely weakened by the invasive emerald ash borer and will be removed in the coming weeks. More from NPS:

Theodore Roosevelt Island is closed for safety in advance of expected thunderstorms, some severe with high winds, this afternoon though this evening. The island will remain closed until tree crews can assess and address damage or new hazards.

A recent tree survey on Theodore Roosevelt Island found extensive damage to trees along the island’s trails from the invasive and deadly emerald ash borer. These diseased and dead ash trees are at an increased risk of falling, especially during storms.

Theodore Roosevelt Island is one of many parks in the Greater Washington Area hit hard by emerald ash borer. The island has many ash trees throughout its 88 acres that have been infected with the exotic beetle. The pest is highly destructive, killing ash trees within two to three years once infected. Dead ash trees rapidly become dry, brittle and hazardous. There is no known cure; once a tree is infected, it will die.

In the coming weeks, crews are expected to begin the removal of the affected trees. More information will be provided in the coming days.
