Seriously, Don't Touch Giant Hogweed!

Originally this post had a more abrupt title, then less so compromised with regular casing and one exclamation point. Just felt like it was important to get the message across.

Many people have had unpleasant experiences with poison ivy and I can attest to carelessly running through stinging nettle several times partly regretting the little renegade session, but Giant Hogweed is more than just a pain-in-the-neck to just wash away, and is in a league of it's own for "don't touch that plant."

It looks like a giant version of Cow Parsnip and Queen Anne's Lace. 
Here is a webpage with a comparison chart: http://www.invadingspecies.com/invaders/plants-terrestrial/wild-parsnip/

Giant Hogweed can grow over 2 metres in height. In addition to its round clusters of white flowers, it has purple spots and tiny white hairlike filaments on the stem. Before it's bloom in mid-August it is also much lower to the ground and without its distinct flowers.

While its mini-me is evocative of the delicate crochet patterns that might adorn the collarbone of her Majesty, Giant Hogweed could bedeck your skin with third degree burns, or cause blindness if even a single drop gets in your eye.

The effects are not immediate, but this plant is phototoxic and the oils will burn your skin after being exposed to light, potentially permanent effects worsening over the course of days without treatment. If you do accidentally come into contact with its toxic oils on your skin, wash the area well with soap and warm water as soon as possible and avoid sunlight for two days, and see a physician.*

If you accidentally get any on your hands, do not rub your eyes!

*Even in the age of knowledge, Google searches, and Mayoclinic, the internet doesn't replace the care of a health care professional. With Giant Hogweed effects may not be immediate but can cause permanent damage without the help of a physician. Including to tough guys (and gals) who "don't go to the doctor".
phototoxicity: (aka photoirritation) A toxic response that occurs after the exposure of skin to certain chemicals and light. It can also occur after systemic (oral or intravenous) administration.

Queen Anne's Lace is a part of the carrot family so I'm guessing giant hogweed is as well. This means that if you're trying to rid your garden of this pain-in-the-neck relative you gotta be careful not only to not touch it,  but to take out the tap root from the ground also.

Giant Hogweed is an invasive species from Asia which (surprise-surprise) was introduced by people, first to England, then to Canada including Atlantic Canada, B.C., Ontario, and Quebec. It competes with native species for resources, and the loosening of soil even after it dies or hibernates during the winter can cause soil erosion.

If you see giant hogweed in your renegading through the forst, reporting the sighting would really help the local environment and fellow outdoorsmen: http://www.eddmaps.org/ontario/ 
(To all who do this, thank you.)

Moral of the story: don't touch giant hogweed.

Dear Readers...

Dear Readers, sustainable city-folk, citizen scientists, wayward wanderers, audacious explorers, and other friends,

Sorry for the shorter and less frequent posts lately. Things have gotten pretty hectic and have changed a lot, but I think mostly for the better. Among other things I have been working on some more creative pieces on lunar-winds, and the voice of Nature Nimbus has also changed. This blog really is for the love of nature in general, so while the style is evolving hopefully that will also allow for more variety and colour in the types of posts that will be here.

There will be a poll on the sidebar for the next little while where you can vote for what type of post you would like to see next. I'd love to hear from you! If there is a specific topic you would also like to suggest, please feel free to submit it in the contact form at the bottom of the page.

Thanks so much for reading and your support!

Happy trails :)

Wind Festival 2015 (Fun Post)

So I have a thing for the wind. Its capricious beauty affects so much physically within an ecosystem, and its unseen and almost spiritual nature is also captivating for those who stop to listen.

In the summer of last year I had the joy of painting kids' faces and working at a skulls and furs booth, as a volunteer at the Kortright Centre for conservation's 2015 Wind Festival. The Kortright Centre is a beautiful raw gem in Southern Ontario that children and their families connect with nature, and nurture respect and love for the environment and our natural heritage.

The wind festival had lots of nature-themed booths and activities for families, and next year I hope to attend as a visitor (and bring my kite!)
