Holly ferns are an evergreen, long-lived, slightly spikey fern. They are well suited to the Yorkshire Dales as they like the deep grikes of open limestone pavement habitats at high altitudes and summer temperatures that aren’t too high!
The core area for Holly fern in the UK is northern and western Scotland above 600m. But it also has important localised populations above 180m in central Scotland, western Ireland and northern England. In the Yorkshire Dales National Park most records were found on limestone pavement habitats in Malhamdale and Ribblesdale.
