I write this during the Jewish holiday of Sukkot. “Sukkot” is the plural of sukkah, the temporary hut that Jews construct for the fall harvest holiday.
I had an epiphany this year: build the sukkah out of buckthorn! Common buckthorn is an aggressive invasive species that plagues the city of Ann Arbor, the state of Michigan, and the Great Lakes region. Since a friend showed me some growing near my house, I notice it everywhere and take pleasure in removing it, as outnumbered as I am in that fight. I’ve cleared it at my previous home in Scio Township, at my in-laws in East Lansing, and now pull it from city parks.
A sukkah needs a roof of s’chach, or cut plant matter. Buckthorn is perfect for this: it’s slender, long, and leafy. In fact, it could do double-duty: it’s ideal for the roof but larger, thicker specimens could also make up the frame of the sukkah (which can be reused from year to year). At the end of Sukkot, the buckthorn can be disposed of in municipal compost carts, where any berries will be destroyed in the heat of the city’s compost piles.
