“…These studies described the singularity of the vegetation in the bermejense sector (biogeographical territory of Sierra Bermeja). At a broader scale, Liétor et al (2003) analyzed the causal relations established between the characterization of the edaphic medium and the availability of the macro-and micro-nutrients required for the development of A. pinsapo. Torres-Cabañete et al As regards Sierra Bermeja, these models indicate a high number of habitable areas for the Spanish fir in almost all its territory above 800-1000 m a.s.l., covering all the mountain ridges that link the present-day Spanish fir forests that have taken refuge in the peripheral peaks of the massif.…”

One of the conservation priorities of the Natura 2000 Network is the ecological connectivity of forests and species of community interest to facilitate compliance with the obligations of the EU Habitats Directive. The location of paleo-populations and past distribution areas is a first step towards creating an ecological corridor which, with the protection enjoyed by Special Areas of Conservation, could positively impact the resilience of forest species in the face of Climate Change. The endangered relict forests of Spanish fir (Abies pinsapo) are endemic in the Serranía de Ronda (Baetic Cordillera, Southern Spain) and form a highly fragmented habitat of community interest. Amongst these forests, the Spanish fir forests that grow on serpentine soils are particularly interesting. This ultramafic mountain range has suffered the highest recurrence of forest fires in all the Serranía de Ronda, and as a result, the Spanish fir forests have been subject to processes of local extinction throughout history. In this research, we used pedoanthracology to uncover ancient locations of Abies pinsapo; in this way, forest fires are the main cause of the disappearance of this emblematic species in Sierra Bermeja, and their charcoal remains allowed us to make a precise reconstruction of its past distribution area. On the basis of the data obtained, an ecological corridor linking these relict forests was proposed. This corridor has now begun to be implemented with the participation of public and private social agents.

Human impacts drive forest structure and diversity. Insights from Mediterranean mountain forest dominated by Abies pinsapo (Boiss.)

Environmental factors and land-use are likely interacting to drive forest structure and species diversity, making it difficult to disentangle their separate impacts. Both components influence the resilience and stability of mountain forests in the Mediterranean Basin, since secular land-use has shaped stands structure and forests dynamics are constrained to the environment. Approaches covering environmental factors and contrasting land-uses are still needed to understand their implications on forest dynamics. We investigated patterns of environmental variables, stand structure and biodiversity in forest dominated by Abies pinsapo for 61 stands over their whole range. In addition, since land-use by local inhabitant could be a key factor, logging intensity was quantified by stumps basal area and recent land-use history was investigated. Partial redundancy analysis (pRDA) was conducted to assess to which degree the structural attributes are related to environmental characteristics and/or the land-use in the main A. pinsapo forests. Environmental characteristics accounted for 13% of the total variance, while the contrasting land-use (Spain vs. Morocco) and the stumps basal area, as indicator of human logging, accounted for 23% of the total variance. Trees species diversity was near 5 times higher in Moroccan stands than in stands from south Spain. According to recent human logging, Spanish stands have been strictly protected, but Moroccan stands showed widespread axe-logging by local inhabitant over the smaller tree sizes. Our results suggest that the preservation of a minor perturbation regimen by local populations enhance and help to preserve the whole biodiversity of this relict habitat.
