2022 Garlic Mustard Pull-A-Thon

Raise funds for your local group by pulling invasive plants

It’s time to get outside to pull together and raise funds during our annual Garlic Mustard Pull-A-Thon. Now in its tenth year, the event encourages folks across southeastern Wisconsin to protect their local woodlands by pulling this invasive plant. More people are participating each year, so spread the word and join us to help stop the spread of garlic mustard!

ENT Team 2021 300This is a terrific opportunity to raise funds for your own organization as well as our regional efforts to fight invasive species. You can form a team, join a team and donate to your favorite team. Our 2022 goal is to collectively pull 20,000 lbs. (10 TONS!) and have a fun time together while protecting natural areas from invasive plant damage. Securing pledges is easy; sponsors can donate directly through our website. Pullers are encouraged to ask friends, family and others to support their efforts in caring for the land.

The pull-a-thon is also a competition, so the team that rises to the top by June 30, 2022 will earn bragging rights and take home the legendary traveling trophy. Our natural areas will only avoid damage from invasives with long-term sustained commitment to their control. Half of all proceeds go to participating organizations that raise funds, and half go to SEWISC. All funds will be used for invasive species education, prevention and control in southeastern Wisconsin. Contributions are tax-deductible.

Here are our Annual Pull-A-Thon objectives (yea, let’s DO THIS!):

  • 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 landowners and managers and strengthen local volunteer efforts.
  • Raise educational funds for SEWISC and our partner organizations.

Even modest efforts can make a big difference toward reducing the impact of invasive species.  Urban landowners as well as those who own and manage larger acreages can now encourage good stewardship and backyard conservation practices by posting these signs. Whether you have rural acreage, a suburban yard, or a city lot, you can help protect the environment by controlling invasive species and promoting that stewardship practice to others.

The high-quality 9x12 inch aluminum signs are available for only $20.00 each, or two for $35.00 (price includes shipping and handling).

To order just download, complete, and send a SEWISC Sign Order Form with your payment.

Quick Guide to Adaptation Planning

for Natural Resources Professionals

Natural resources planning activities are constantly changing to accommodate new challenges, and it is becoming increasingly important that conservation and land management activities intentionally consider a changing and uncertain climate.

Created by the Northern Institute of Applied Climate Science in collaboration with the USDA Northern Forests Climate Hub, the Quick Guide to Adaptation Planning for Natural Resources Professionals was developed as an entry point to adaptation planning for natural resource professionals. This Quick Guide gives you a starting point to help you design and implement adaptation actions in your work, with a focus on the project level. It draws on a five-step process to help you consider how climate change will affect your lands and your associated goals for natural resources management.

By intentionally considering the potential impacts, challenges, and opportunities from climate change, you can then use this lens to identify actions that enable ecosystems to cope with stressors and adapt to changing conditions, while also addressing your conservation priorities.
