Abstract
This paper summarizes the preliminary results derived from the OAPN project Vegetation resilienceand vulnerability in two highly diverse Iberian enclaves: Doñana and Sierra Nevada (261/2011 OAPN). Farfrom being randomly chosen, these contrasting geographical settings were selected due to their potential to serve as models for the study of vegetation dynamics. Their important positions withinIberia, their uniqueness, ecological diversity and complexity makes them especially interesting ascritical locations for monitoring of environmental change. Patterns and processes related to resilienceand vegetation response to recurrent perturbation regimes once explored in these systems can beextrapolated to analogous systems and thus contribute to the improvement of conservation practicesand policies. Our results complete the chronological frame for the sedimentary record of Doñana and Sierra NevadaNational Parks. The taxonomical resolution of the fossil assemblages has been significantly improved,achieving a detailed record of fossil floras, especially in Doñana NP.Our results reconstruct the environmental history of Doñana NP and support the indigenous distribution of stone pine (Pinus pinea) and the past presence of Scots pine (Pinus sylvestris), cluster pine (Pinuspinaster), waltnut (Juglans) and sweet chestnut (Castanea sativa) in SW Iberia. Although present in thefossil assemblages, the occurrence of cedar (Cedrus) remains unresolved. In Sierra Nevada, the fossilassemblages evidence a transition from a humid and warm phase during the early Holocene towardsa colder, arid phase that intertwines with anthropic activity in the explanation of the current vegetationlandscapes of this southern mountain range.
