Métodos para el censo y seguimiento de plantas rupícolas amenazadas

摘要: The conservation of threatened flora needs information on the distribution and occupancy area, as well demographic parameters like population size, structure, dynamics. This kind information, however, is difficult to obtain for rupicolous plants due their inaccessibility. Given that in mountain ranges endemic often linked rocky habitats, we have developed some specific methods carry out reliable censuses monitoring this habitat. We describe five techniques used Spanish Pyrenees, nested three levels intensity, order get necessary classify species, take management decisions guarantee persistence. Such variety provides flexibility fit best method each particular case, while allowing comparison same species sharing an unusual
