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. Be a Citizen Scientist— We are asking you to help us scout areas near you where it is likely to be found, so that emerging infestations can be documented, treated and monitored.

One of the basic principles of invasive plant management is early detection. To that end, IPAW is sponsoring a reward program to encourage and provide incentive for citizens of the state to look for and report prohibited invasive plants.

Climate change means new and stronger weeds. In this video, University of Wisconsin-Extension weed specialist Mark Renz shows how climate change will turn some of our existing weeds such as Canada thistle into super weeds. Plus, a look at some new weed threats from the south.

White-nose Syndrome is a mysterious disease that is killing bats across the northeast United States. Many research projects are underway to help in the fight against WNS, from researching fungicides to modeling the spread and affects of the syndrome. If you would like to help there are many ways in which you can:
  • Report any unusual bat activity (bats flying in the daytime) or unexplained bat deaths to your regional TWRA office. Or check out the Report a Bat Link on this website.
  • Donate to a number of funds collecting money for WNS research (see National Speleological Society and Bat Conservation International pages below).
  • Adhere to state and federal cave closure advisories.
  • Encourage state and federal agencies to assist in WNS research and monitoring activities.
