Fig Buttercup (Ficaria verna, formerly Ranunculus ficaria) is an early-blooming perennial with origins in Europe and northern Africa. It is also called Lesser Celandine, and it is sometimes confused with Marsh Marigold (Caltha palustris). More recently, its behavior has transitioned or is in the process of transitioning to that of an aggressive invasive species that threatens bottomlands throughout its adopted range. Even after its invasiveness was recognized, many people did not anticipate that it would behave invasively in the South, as it has begun to do.

The rapid spread of buffelgrass through the Sonoran Desert rivals climate change and water scarcity as our region's most pressing environmental issue. Buffelgrass is one of many plants that were brought here from other parts of the world. Lacking the insects, diseases, and other organisms that helped keep them in check back home, some have spread like wildfire, much to the detriment of our native plants and animals. Buffelgrass is the worst of these invasive plants because it is not only invading our desert, but transforming our formerly fire-proof desert into a fire-prone grassland. The fight to control buffelgrass is the fight to save an ecosystem and some of the most magnificent stands of saguaros in the world. Volunteer for a buffelgrass pull, register your own buffelgrass pull, or request a presentation or ID guide.

Something troubling is taking hold in Oregon. Strange, exotic plants and animals are showing up in places where they don't belong. They are invasive species, and they're taking over landscapes, driving native wildlife away, and making everyone from ranchers to fishermen to wildlife managers nervous. What are these invaders? Where do they come from? And what can we do to stop them?
