Why care about invasive plants?

If it’s green it’s good, right? Well, not quite. Invasive plants do add green to our surroundings, some quite strikingly. In the process, though, they cause serious environmental damage. Let’s take a deeper look at the problem with invasive plants and how they disrupt an ecosystem. 

Invasives tend to grow quickly, out competing native vegetation for available nutrients. Invasive vines, especially, can overgrow native trees and plants, smothering out the sunlight. Native wildlife loses habitat when these changes occur. 

Soil chemistry suffers at the hands of invasives, as well. When native vegetation is thriving in healthy soil, their root systems create stability, supply water and essential nutrients, and return more nutrients when they decompose. They help maintain the soil chemistry, its physical structure, and sustain essential soil microbes whose job it is to help store and supply water to plants. Non-native, invasive plant roots interrupt these unseen but essential processes which are the foundation of a healthy forest.

Nearly 100 residents have joined The Woodlands Township Invasive Task Force to combat these problems. This group of trained volunteers removes invasive plants from pathways and greenbelts, helping sustain our native species. You can help, too.  As summer turns to fall, many invasives are at their most prolific and your help is needed. Keep your eyes open and report invasive species on the pathways when you see them. Not sure which are the bad guys? How about watching for just these three: Japanese climbing fern, nandina (sometimes called heavenly bamboo), and elephant ears. Learn and identify more with this guide to invasive species of the Galveston Bay Area. Then use The Woodlands Township 311 app on your phone to report your sighting of these plants.  

If you would like to join the removal work, join us on August 15, 2020. The Environmental Services Department will host a training class on invasive species. You’ll leave informed, inspired and ready to join the Task Force. Register for the class using the link below.
