Invasive, non-native shrubs frequently leaf out earlier in the spring and hold onto leaves later in the fall than natives, out-competing native plants and shading the forest floor at times when other species depend on the sunlight. Authors of a new study used data collected by Nature's Notebook participants to find leaf period was up to 77 days longer for invasive species compared to natives. Better knowledge of how invasive shrubs negatively impact natives can help stem the purposeful spread of these plants by humans and protect native species and their ecosystems.
