This thesis is aimed on research of spatial distribution of trees on peatland Malá louka and their dependance on spatial covariates of distance from water reservoirs and terrain elevation. It also approximates volume of tree biomass that were produced spontaneously over approximately 60 years till its thining in 2014s revitalization and therefore it tries to reconstruct the state of stand before that revitalization. For spatial analysation a spatstat R library was used. Data were collected with Fieldmap and results are, that birch and alder can be found closer to water reservoirs while beech stay further away and spruce can be found in every distance. From result we van conclude, that revitalization in 2014 was primarily aimed to cut down birch.
