The management of an inaccessible plant in extinction risk. Borderea chouardii was the first plant species with an official recovery plan in Spain. In this paper we present the demographic and reproductive information gathered for this small rupicolous plant, and the main management actions carried out over the last decade. Despite the inaccessibility of most plants in the only known population in the world, we could establish the unusual longevity of this species, that population dynamics is extremely stable, and that there is no evidence of reproductive problems (high levels of seed production and viability). Its dispersal system, however, adapted to seed release near the mother plant, prevents it from expansion to new favourable habitats. Our goal was to increase our access to different areas in order monitor the performance of plants of different sexes, sizes and ages, to recover 90% of seeds naturally lost during seed release, and to use them for many different purposes: reinforcement of the populations, founding of new populations, seed storing in a seed bank, development of an in vitro bank, genetic analysis, and the production of ex situ adult plants. Several awareness actions have also been carried out among students and climbers. |
