2016 Garlic Mustard Pull-A-Thon

PULLING TOGETHER through some friendly competition

Our Garlic Mustard Pull-A-Thon is an annual fundraising event, where we encourage folks throughout southeastern Wisconsin to protect the woodlands of their neighborhoods by pulling this invasive plant.  Our 2016 goal is to collectively pull 5,000 pounds and raise essential funds for the fight against invasive species – so join us! 

springnews 1aThe pull-a-thon is a competition, a fundraiser, and a way for people to join together and have a positive impact on their environment.  Our natural areas will only avoid damage from invasives with a long-term sustained commitment to invasives control.  Help raise funds for a sustainable invasives program at the same time that you help to reduce garlic mustard seed production in 2016.

All proceeds will be used for invasive species education, prevention and control in southeastern Wisconsin and contributions are tax-deductible.  The Pull-A-Thon Traveling Trophy and bragging rights will be awarded to the Team that collects the most pledges and pulls the most garlic mustard by June 30, 2016.

Pull-A-Thon Objectives:

  • Promote repeated control and proper disposal of garlic mustard and dame’s rocket in our parks and natural areas.
  • Promote public awareness of invasive species issues.
  • Share control methods and best management practices with land owners and managers and strengthen local volunteer efforts.
  • Raise operational funds for SEWISC and our partner organizations.

Invasive Plant Management Techniques Course

Don’t miss this hand’s on class

springnews 5Many of us work to control invasive plants in the areas we care about.  Take this class to ensure that you are using the most appropriate, efficient, up-to-date, and least environmentally damaging methods in those efforts.

Available for 0.8 CEU

After an introduction to the general ecology of the five functional groups of invasive plants (shrubs, perennial forbs, clonal perennials, grasses, and annuals/biennials), we will discuss, demonstrate and practice all applicable control methods (chemical and non-chemical) for these five plant types.

Topics will also include: 1) Identification of our common and relatively new invaders, 2) Planning and strategy for an effective control program, 3) Use of hand tools and herbicide application methods, 4) Herbicide concentrations, mixing, and safety, 5) Restoration strategies for badly infested sites, and 6) Record keeping.  Safe chainsaw use for woody species will be demonstrated only.  Several handouts and reference materials will be provided.  Register today!

Education on the Go

Spreading the word on invasive species

springnews 7Our table-top exhibit is always on the go; traveling to conferences, fairs, libraries, and workshops throughout our 8-county region and exhausting the supply of our educational brochures and handouts.   Through a generous grant from springnews 6Natural Resources Foundation of Wisconsin’s C.D. Besadny Conservation Grant Program, we updated and restocked our supply of membership brochures and purchased “Stop Aquatic Hitchhiker Bobbers” which will be distributed to the public to educate them about the need to clean invasive plant and animal debris from their boats after recreating in our lakes. We also printed and distributed our attractive ready-to-hang SEWISC posters to nature centers and other public facilities in an effort to educate the many individuals who visit their facilities. 

Teaming-up with Hunters and Anglers

To protect wildlife habitat

Often overlooked as conservationists, hunters and anglers have been and remain committed, key supporters of conserving Wisconsin’s beautiful natural resources.  They know first-hand about the impacts that non-native invasive species are having on our hunting and fishing habitat such as forests becoming ugly thickets of honeysuckle and buckthorn, or lakes made almost unfishable by Eurasian water-milfoil or zebra mussels. Over time, invasive species can ruin our favorite hunting and fishing spots and perhaps more than any other group, hunters and anglers are bearing the brunt of the impacts of invasive species.

Through a partnership with the James E. Dutton Foundation, Inc. we recently reached out to hunters and anglers in southeastern Wisconsin to help them work together with environmental nonprofits and government agencies to control the degradation of terrestrial and aquatic wildlife habitats by non-native plant and animal species.  Educational materials were prepared and sent to nearly 9,000 individuals through this effort.
