Matthew Bruckner and his two kids spent a Maine vacation eating wild blueberries straight from the bush. Returning home, they wondered what else they might forage. Soon the Washington, D.C., family found wild blackberries in the alley behind their house, in dirt patches around the city, and in a nearby natural urban woodland.
It turns out the foraging wasn’t just family fun—it was helping rid the neighborhood of an invasive species.
Invasive species are plants, animals, and other organisms that aren’t native to an area and are harming the ecosystem. These invaders often don’t have animals that eat them in their new environment, allowing them to outcompete native organisms or alter the habitat.
