Abstract

This paper presents the coenological analysis of a few lowland beech forest stands. The studied area is located in the north-eastern part of Croatia, in the Baranja region (Titelicum floral subdistrict). Several montane plant species are found int he investigated stands, probably originating from the "Beech I. " period (from 3000 B.C. to 800 B.C.), whereas several submediterranean species probably have survived from the "Oak period" (from 5500 B.C. to 3000 B.C.). Based on former research results, these lowland beech stands can be considered a beech subassociation of oak-hornbeam forests of the plains {Circaeo-Carpinetum fagetosum). The presence of some submediterranean plants call the attention to the relatedness of these stands to oak-hornbeam forests (Asperulo taurinae-Carpinetum) and beechwoods {Helleboro odoro-Fagetum) of the neighbouring Mecsek floral subdistrict (Sopianicum). These beech stands are of high significance in terms of floristic and vegetation history, thus deserve strict protection.
