FAQs and Quick Tips
What species does TIP focus on?
Our priorities include species on the WI DNR's Regulated Invasive Species List. We also work on emerging threats and support landowners with widespread species that are highly impactful. The presence of invasive species can vary by location, but buckthorn, garlic mustard, wild parsnip, and Japanese knotweed are some of the more aggressive and problematic species in the TIP region.
How do I report an invasive species?
You can report sightings using apps like EDDMapS and MISIN, both linked above. You can also reach out to TIP by sending us a photo or two, location info, and a brief description.
I found an invasive plant in my yard. What should I do?
Start by correctly identifying it using an app like Seek or iNaturalist, or contacting TIP. Then remove the plant using safe methods, dispose of it properly, and replace it with native plants. TIP can advise you or help connect you with resources.
Can I request a site visit?
Yes! Depending on staff availability and priority level, we can visit your property to identify invasive species, offer management recommendations, and help you plan steps to control the species. You can contact us via phone, email, Facebook message, or on our reporting box under "Invasive Species."
Will TIP remove invasive species for me?
In many cases, yes, especially if the species is prohibited. For work on private lands, we require a Landowner Participation Agreement on file which allows TIP to safely and legally conduct invasive species control on your property. While we cannot assist with every infestation, we may provide removal, monitoring, and management recommendations when resources allow.
Does TIP provide herbicide?
We don't supply herbicide for personal use, but we may use it during TIP-organized treatments when appropriate. We're always happy to recommend safe, effective options and application tips for landowners treating invasives themselves.
Can I get involved?
Yes, definitely! You can sign up for our Mailing List to receive updates from TIP, and you can sign up to become a TIP Volunteer. People of all ages are welcome, but youth must be supervised. You can also help spread awareness in your community by planting native species, practicing and promoting clean gear habits, or share TIP's events and updates on your own social media pages. If you have further questions, please call or email us - we're happy to help you, help us!
Tips from TIP:
Identify Invasives
- Look for common invasive species like garlic mustard (spring to early-summer), wild parsnip (summer), and common and glossy buckthorn (late-summer to fall). You can use apps like Seek, iNaturalist, or EDDMapS to help identify plants in your area.
- Wear long pants, closed-toe shoes, and gloves when you're outdoors looking for invasives. Always be sure to wear sunscreen during your time outside and to check for ticks after!
- Pull small plants by hand, being sure to get the roots! Cut larger shrubs low and treat stumps when possible. You should bag all seedheads of plants to prevent the spread - do not compost invasive plants!
- Clean your boots, bikes and boats after use to ensure there aren't any invasive species debris stuck to you like seeds or small creatures. You should not transport firewood or any invasive plants. Choose to plant native species in your landscaping instead (resources above!)
