État de la populationTexte officiel évaluation IUCNExpert

There is limited information on this species' population size. Across the Iberian peninsula the population is not contiguous, but is fragmented into 10–20 sub-populations. Population is considered declining within Spain (Blanca et al. 2000). There is no population information available for the species within Africa.

Description complète des menacesTexte détaillé évaluation IUCNExpert

The species is threatened by the timber trade and is vulnerable to forest fire (Blanca et al. 2000). In the future the species is likely to become increasingly threatened by climate change due to its susceptibility to drought (P. Garcia Murillo pers. comm. 2016). There is also concern over the species' decline in Spain and its fragmentation into 10–20 subpopulations. Within Portugal the species is locally affected by eucalyptus plantations (A. Buira pers. comm. 2016). Native forests are cleared to establish plantations of this invasive, showing a decline in habitat quality and area (Sousa et al. 2000). The threats to the species within North Africa are not known, however it is likely to be similarly affected.

Habitats préférentiels (classification IUCN)

Mesures de conservation recommandéesStratégies de conservation IUCNExpert

This tree is recorded in 49 ex situ collections (BGCI 2016). This species is listed as Vulnerable in Andalusia, Spain (Blance et al. 2000) and Near Threatened within Europe where it has been recommended that the species' habitat become protected. Population trends and threats to species should be assessed within North Africa, to better understand what is happening to the species across its range.
