Relations between climax vegetation and isobioclimates in the Northwest of Spain (Leon province)

This paper determines the isobioclimates existing in the province of Leon (north-western Spain) as the result of combining macrobioclimates, bioclimates, bioclimatic variants, thermotypes, ombrotypes and their corresponding bioclimatic horizons, all obtained from the analysis of eighty-three transects distributed throughout the study area The relations between isobioclimates and climax vegetation are also analysed. Twenty-six different isobioclimates are identified (15 temperate and 11 Mediterranean). Most vegetation series develop in the supratemperate humid and hyperhumid isobioclimates.
