Lungwart (Lobaria pulmonaria) is a lichen known in the Gitksan language as gwilahl gana’w or frog blanket. As frog blanket is clearly a better name, I vote we use this instead. Frogs are amazing but I digress.

While it grows plentifully here in the forests of the southwestern British Columbia coast and is not of conservation concern, it is in decline is other areas of the world and should not be harvested. In some regions it is a designated of conservation concern and carries legal protection. Detecting its presence can also be used as an indicator of a healthy older forest with clean air.

TLDR: 62 grams of fresh lichen, 30 grams of white wool. Wool was pre-mordanted with alum because that’s what I had on hand. I understand that this lichen that an alum mordant or not does not alter the final product (but I have not tested this yet).
