Our Partners at Oneida County are running their annual Northwoods Invasive Species Poster Contest! It's open to students across Wisconsin and expanding every year.  Check out the flyer to the right for more information.  Great for any students who are interested in both science and the arts! 

Our Annual Meeting is again approaching!  All WHIP Partners, collaborators, colleagues, friends, and members of the public are invited to join us on March 21, at the Woodruff Town Hall, for a morning of updates, speaker presentations, and valuable discussion on stories and challenges of invasive species in the Northwoods!  See here for the official flyer

Afternoon business meeting agenda will be posted soon!


  WHIP recently did a  follow-up site visit to our patch of Wild Chervil plants which was reported to us last year by a volunteer, Bill Jaeger.  This is a site near the town of Lake Tomahawk, located in the right-of-way along a county highway.  The good news is that it looks like there has been very little re-growth (<10 plants) at the site, which means the herbicide application was effective.  Our partner group WDNR carried out the treatment last spring.  Surveys up and down the road for several miles in each direction have shown no further spread of the plant.  

     Wild Chervil (Anthriscus sylvestris) is a prohibited species regulated under NR 40, our state's invasive species legislation.  It is an herbaceous biennial or short-lived perennial from the parsley family (similar to Queen Anne's Lace!), introduced to North America from Europe.  It was first brought to North America as part of European wildflower seed mix used for plantings along hedgerows and meadows.   The plant forms a rosette of leaves in the first year, then flowers and produces seeds in the second year.   It is easily spread to new locations, and with very few  checks on its population, it can quickly take over an area, displacing native species and forming dense stands that are difficult to control.

     We thank Bill and other volunteers who have their eyes peeled to new plants on the landscape, and we are grateful to our partners for cooperating with WHIP to get plants like this treated quickly.

Thanks to our grant award from the WDNR, WHIP is able to expand our Toolkit and increase the variety of tools and equipment we have available for loan to citizen groups who wish to carry out invasive species removal on their land or a natural area they care about.  We will have workgloves, shovels, pruners, weed diggers, and a couple of large uprooters! Stay tuned for more information as our deliveries arrive and we get the details published!
