Resumen

Cotoneaster granatensis (Rosaceae) is an endangered species in the Valencian Community with two natural populations known and 37 wild plants located in Alicante province. The strategy applied for conservation of this species comprises three steps in a cyclical method: in situ (first step) - ex situ - in situ (second step). Current conservation status for this species has been evaluated as a part of the first step in situ actions. Ex situ conservation activities consisted of germplasm conservation on seed banks, creation and maintenance of collections of livings plants and production of new plants in order to develop reintroductions (in situ actions: second step) in natural populations. The seed germination is a complex issue, but an effective protocol has been established reaching values over 60% of germination. The plant propagation by cuttings has not been successful. In situ actions such as reducing the threat of herbivory has been also essential to enhance natural populations. The initial results on plantations in the natural habitat show high survival rates of specimens.
