Wild parsnip sap can cause painful, localized burning and blistering of the skin. – New York State Department of of Environmental Conservation
Wild parsnip going to seed. The sap in this widely spreading invasive plant can cause severe burns.
A few weeks ago we discussed the invasive wild parsnip as a hidden danger for weekend weedwackers. Now it is much more obvious with its bright yellow flowers, but if you are looking to control it now, straight mowing is off the table. Some of the heads are going to seed and mowing will simply distribute those seeds, ensuring a new crop of wild parsnip next year.
Whether you choose to dig out the root, cut the root an inch or two below the soil, or mow, first cut the seed head off with clippers and put it in a plastic bag. The bag can then be left in the sun to rot the seeds before disposal. And don’t forget to wear protective clothing to prevent any sap from reaching exposed skin or eyes.
Use a boot brush to clean mud and seeds off your boots. Remember to check the tread!
This is also the time of year when seeds of this and other invasive species can be accidentally transported by hikers and dog walkers. Avoid brushing against plants. Check shoes, clothing, and gear after leaving an area. Remove any seeds that are found and seal them in a plastic bag. (This can double as a tick check!)
For more information on preventing the spread of invasive species while hiking, biking, camping, and, well, any outdoor play, a great resource is PlayCleanGo. And consider taking their pledge to Stop Invasive Species in Your Tracks.
Let’s stay safe out there!

by Joellen Lampman Comments Off on It’s New York Invasive Species Awareness Week
The mission of the New York Invasive Species Awareness Week (ISAW) is to promote knowledge and understanding of invasive species and the harm they can cause by engaging citizens in a wide range of activities across the state, and empowering them to take action to help stop the spread.
While we won’t be able to gather for invasive species identification walks, removal projects, or in-person presentations, there are plenty of online opportunities to increase awareness. And the good news is that you will have access to statewide opportunities. Presentation topics run from learning how to identify plants information and enter it into iMapInvasives to the more specific info on beech leaf disease, crayfish, “murder hornets”, how climate change, and deer, impact native plants and pave the way for invasives, and more. For a full list of virtual events, visit https://nyisaw.org/events/.
And there are numerous challenges offered this year. Be sure to use the hashtag #NYISAW! ISAW Social Media Challenges, many suited for the kids, include:
Sunday – learn about your local invasive species and share a selfie
Monday – create some Invasive Species Art!
Tuesday – use the Agents of Discovery app to learn about invasive species
Wednesday – increase others’ awareness by creating a banner and hanging it in your window
Thursday – help track invasive species in NYS through iMapInvasives. New to iMap? There will be an online training at 1:00
So download the Seek app, head to the backyard and identify some invasive species. Upload the information to iMapInvasives. And then feel free to remove them. This weekend I’ll be CAREFULLY digging up wild parsnip along my roadside. How about you?

“As everyone knows, when fighting a zombie, you grab a shovel and aim for its head. The same with wild parsnip, except you aim for its feet.” – Paul Hetzler
That’s a lot of green. Would you have noticed the wild parsnip? The celery like stalk is a good clue.
There is no lack of invasive species in New York – but some do raise more of a concern than others. One such is the wild parsnip. In a few weeks it will proclaim itself with its wide, yellow flower cluster. But it is currently a few feet tall and whether it is bedecked with flowers or not, its sap is just as risky. So if your weekend plans involves weed whacking, beware!
Wild parnsip will soon be in flower, but it is just as dangerous, and harder to see, in the pre-flowering stage.
According to the New York Invasive Species Information Clearinghouse, wild parsnip produces furanocoumarin, “a compound in its leaves, stems, flowers, and fruits, that causes intense, localized burning, rash, severe blistering, and discoloration on contact with the skin on sunny days”. Avoid the sap and avoid the chemical burns.
Digging out the root, mowing, and herbicides can be effective in managing wild parsnip, with the caveat that you protect yourself from any and all contact with the sap.
If you want to learn more about wild parsnip and its management, our favorite guest blogger Paul Hetzler covered it well and humorously in his blog, Vengeful Veggies.
