This species is known only from the summit of Windsor Castle and surroundings rocks (Rauh 1998), although It may also be present on the rocks of the Montagne des Francais, further South. The exact extent of occurrence and area of occupancy is not known but E. bulbispina is likely to be restricted to a very small area, outside any protected areas. It thus qualifies for VU D2.
