A species level classification of maquis would be useful in understanding vegetation structure and dynamics, which would be an indicator of degradation or succession in the region. Although remote sensing was regularly used for classification in the region, maquis are simply represented as one to three categories based on density or height. To fill this gap, we test the capability of Sentinel-2 imagery, together with selected ancillary variables, for an accurate mapping of the dominant maquis formations. We applied Recursive Feature Selection procedure and used a Random Forest classifier. The algorithm is tested using ground truth collected from site and reached 78% and 93% overall accuracy at species level and physiognomic level, respectively. Our results suggest species level characterization of dominant maquis is possible with Sentinel-2 spatial resolution.

One suborder, one association and six new subassocaitions are proposed : Juniperenalia nanae, Echinospario pulvinformis-Cytisetum oromediterranei, Cytiso-Echinospartetum barnadesii ericetosum arboreae, Junipero-Cytisetum oromediterranei adenocarpetosum hispanici, arctostaphyletosum crassifoliae, ericetosum aragonensis, genistetosum cinerascenis and populetosum tremulae. The main syntaxa of the Pino-Juniperetea class are typified. It is included a syntaxonomic scheme of this class, with biogeographical, ecological and floristic diagnoosis of the units admitted in the Iberain Peninsula. New releves, a synoptic table and propositions for nomenclatural correctins are provided for the syntaxa of the alliance Pino-Cytesion oromediterranei. Three new nomenclatural combinations are salso proposed : Echinospartum ibericum, E. ibericum subsp. pulviniformis and Thymus praecox Opiz subsp. penyalarensis.
