Early Holocene vegetation in the Ayllon Massif (Central System Range, Spain) based on macroremains. A paleoecological approach

摘要

We present a palaeoecological study of well-preserved vegetal macroremains in Spain, which age range (10,025-5371 cal yr BP) confers it an outstanding interest, because for the first half of the Holocene, palaeobotanical data are extremely scarce in the Iberian Central System Range. We found, for the first time in the easternmost zone of the Central System Range, macroremains belonging to the genus Pinus; these have specifically been identified as Pinus cf. sylvestris and Pinus gr. sylvestris. These findings provide valuable information on the role of the genus Pinus, regarding the natural character of these pine forests in this relatively unknown region.
