Despite being a magnet for walkers, the hillfort at Penycloddiau in the Clwydian hills is in an under-recorded grid square. It lies on the boundary of Flintshire and Denbighshire vice-counties and we in Flintshire have only part of the tetrad.
Four botanists braved the tiny lanes on the approach to the site and we headed up the hill to see what we could find. Upland acid sites which are sheep grazed are very often dull botanically, unless there are pockets of greater habitat diversity. Above, botanists explore a small side valley in search of wet habitats.
We had a good look round and managed 122 species for the day.
