Anyone who is interested in native plants will soon come across the term “invasive.” Invasive species and habitat loss are the main causes of biodiversity loss and destruction of native plant species worldwide. Although most of us have a general sense of what is meant when a species is deemed invasive, there is also a lot of confusion as to what an invasive plant is, what it does, and what should be done about it.

With this introduction, we are beginning a series of articles about invasive plants. In this first article we will define what is meant by an “invasive plant.” We will discuss why they are bad for our native ecosystems and discuss, in general, how they can be controlled. We will also point you towards online resources about invasive plants. In each subsequent article we will concentrate on a single type of invasive plant, giving information on how to identify the plant, where it came from, how it got here, the specific damage it does, how best to control it, and some native alternatives to plant when it has been removed.
