striations in the magnetic map, which may indicate ploughing, followed by spots which may have been campfires. Jeffrey Davies' excavation trench, which he dug in 1974, caused a large line of static. Protecting the site Until very recently, the fort was covered with gorse bushes. This plant has invasive roots, and scientists were worried that it might be damaging the remains of Trawscoed Fort. A group from FC Wales removed the gorse, and foresters laid down hay from the nearby Penrhyncoch meadow. The seeds contained in the hay will fall down and germinate, thus replacing the gorse with a layer of grass. This will have the added benefit of attracting birds and butterflies to the site.
