A plant is just a plant, right?

Not really. There are indigenous or native plant species and there are non-native or exotic plant species, some of which are invasive and causing huge problems. Twinleaf (Jeffersonia diphylla), shown at left, is a native perennial wildflower in the eastern U.S. It emerges in the spring and then dies back except for its roots. Its flowers are important to pollinators and its seeds are dispersed by ants. Twinleaf and other spring ephemeral wildflowers are being pushed out by garlic mustard, fig buttercup, English ivy and other invasive plant species. In the Weeds is working to turn the tide against invasive plants, animals and microorganisms.

Invasive Species Mapping and Reporting

More than 300 invasive plant species have been identified as a threat to native ecosystems in the mid-Atlantic region (e.g., Oriental bittersweet, shown at right, introduced for its attractive fruits). The Early Detection and Distribution Mapping System (EDDMapS) was developed by the Center for Invasive Species and Ecosystem Health at the University of Georgia in 2010. The Mid Atlantic Early Detection Network (MAEDN) smart-phone app, was developed to facilitate field identification and reporting of invasive plants, animals and pathogens. Download the app today (www.maedn.org), and start reporting!
