Research output: Contribution to journalArticleResearchpeer-review


Spiraea crenata subsp. parvifolia is an endemic taxon from northeastern Iberian Peninsula present in Collsacabra (Osona). The aim of this work is to define the extent of this population, to characterize its demographic structure and to analyze its conservation condition. Most of the enumerated individuals live in a main nucleus surrounded by smaller nuclei. The stability of the environment it occupies permitted us to assess the evolution of the population and the IUCN category of threat, which is now considered « endangered». Management measures are proposed which seem appropriate for the conservation of this population. © Patronat d'Estudis Osonencs.
