"Look up the next time you’re in a park — any park — in the Mid-Atlantic. You’re likely to see vines climbing toward the treetops. These invasive vines can be deadly — not just to the trees they are overtaking, but to the larger ecosystem.
Elizabeth Hoge, of Montgomery County, has a good view of invasive vines on her way to work each morning. It prompted her to ask WAMU’s What’s With Washington: “What’s with all the vines around Rock Creek Park? Is anyone else worried about these vines pulling down the trees?”
On a drive through the park, she pointed them out: “It’s just tendrils of vines, reaching up into the sky to grab and attack trees.” Outside the car window, the trees no longer look like trees — their limbs indistinguishable under a malignant carpet of green. As Hoge drives this route each day she shakes her fist at the vines and wonders, “Is anything being done?”"
