The presence of unusual artic-alpine plant species in the Upper Teesdale nudges me to walk about two miles along the river Tee in the beginning of Spring to witness the flowering of the Spring gentians. What makes this place favourable to the gentians is the rocky outcrops of unaltered limestone, an upland setting which retains harsh climate, and unfavourable mineral content of soils to the growing of grasses that could compete with these rare flowers. Much of Teesdale has been designated as a protected conservation area.
