The aim of this work was determination of dynamics of akrotelm layer on the peat-bog Baligówka in the Orwsko-Nowotarska Valley. This object both in the past and at present undergoes strong pressure as a result drainage, exploitation and fires. Investigations were carried out by use of the dendrological method according to Korczagin [1960] and Piczugin [1967] showed that in spite of strong anthropopressure, development of all the organic layer as well as peat is characterized by mean yearly dynamics of growth. Comparison of results obtained on this object with the ones investigated in this region shows strong influence of hydrological conditions on dynamics of akrotelm layer development. The raised peat-bog Baligówka is highly dried object and similarly as the peat-bog Bór za Lasem is characterized by the lowest growth of the akrotelm layer, amounting 3,78 mm in year.
