Rubus trelleckensis is a rare endemic bramble found only in one IQ-km square near Trelleck, Gwent (v.c. 35), Wales. It is a perennial which flowers from mid-July to mid-August, and sets abundant fruit but probably does not spread vegetatively. A field survey was carried out in 1998. Five small populations were found, all in locations which were probably at one time either open heath or open Birch-Oak woodland but are now either conifer plantation, or conifers mixed with broad-leaved trees. Plants were most frequent on acidic podzols in sunny but sheltered spots on level ground. The main threats to its survival are change of land-use from forestry or changes in forestry operations. Seeds have been deposited in the Millennium Seed Bank at the Royal Botanic Gardens, Wakehurst Place.
