A Yoshino cherry blossom tree that has begun to bloom is seen with the Washington Monument in the background, Monday, March 20, 2023, along the tidal basin in Washington. Some of the trees have been damaged by regular flooding in the Tidal Basin due to rising seas levels. The 107-acre man-made reservoir where the largest concentration of trees is located now floods twice a day at high tide, submerging a stretch of sidewalk next to the Jefferson Memorial, like this tree's location. During heavy rains that routinely occur in Washington, the floodwaters completely overflow the sea wall in multiple locations and soak the tree roots with salty brackish water, damaging the trees.
