Here in Oregon, gorse is a bad thing. Gorse was planted in Bandon as an ornamental in the 19th century, and it now dominates open fields for miles in each direction. It is extremely invasive, and crowds out the native vegetation. It has thorns, causes a rash when you touch it, and is an extreme fire hazard. Once it starts burning, you can't put it out.
Perhaps it makes the Bandon courses look more authentic as links courses, but it's awful.
In 500 years, the only two plants left will be gorse and Roundup-resistant bent grass.
