Abstract
During the survey of the Ma艂y Borek nature reserve (August贸w Forest, NE Poland) 236 species
of vascular plants were recorded, including 10 plant species red-listed in Poland and 19 species protected
under the Polish law. The most valuable species were sedges typical of the boreal coniferous forests: Carex
vaginata, C. globularis and C. loliacea. The presence of neophytes was very limited (1,3% of the flora) in the
area studied. The principal aim of the establishment of the reserve was the conservation of old-growth
coniferous forests with long ecological continuity. Since the reserve studied consists mainly of old-growth
coniferous forests, the number of species regarded as ancient forest indicators is lower (54 species) than
in the well-preserved reserves with deciduous stands in north-east Poland, but still rather high. The most
valuable, threatened species are bound to wetland forests that are presently disturbed due to drainage.
Restoration of the former hydrological conditions is essential for the preservation of the vascular plants
in the reserve
