Abstract
This paper presents results of
investigation on
peat and lacustrine sediments from the Kładkowe Bagno peat-bog located
in the
Puszcza Knyszyńska Forest. Using analysis of plant remains from
sediment
samples, vegetative and generative finds were identified which allowed
describing peat units. Basing on these results, reconstruction of
subfossil
vegetation and palaeoenvironmental changes in the mire was made.
Altogether 4
subassociations of Sphagnetum magellanici were described, which
delivered
information about humidity of the mire surface during peat forming
processes.
Stages of deposit development were dated by radiocarbon method.
Accumulation of
the oldest sediments in the southern basin took place in the Late
Glacial. Peat
of the northern basin started to accumulate in the Atlantic period. The
both
parts of the mire aggregated probably 400 years ago.
