Summary
The aim of the thesis is to map the changes of vegetation in the top parts of the peaks Šerák, Keprník, Červená hora. Historical and current aerial photographs and other supporting materials are used to identify and map, mainly:
- forest line shift,
- integration of dwarf pine growth,
- integration or disintegration of spruce growth.
The current alpine timberline is determined by a point cloud created from aerial photographs. The occurrence of dwarf pine is obtained by manual vectorization. These current data are compared with existing data from the period 2003-2009. Due to the non-detail of archival aerial photographs, it is not possible to determine integration or disintegration of spruce growth. This statement is presented by comparing the areas of treetops in the author's available aerial photographs on a representative area of one hectare.
The outcome of the thesis is the determination of the current alpine timberline, map and statistical comparison with the timberline in 2005. The current occurrence of dwarf pine is also mapped, the work deals with mapping its increase and decrease compared to 2003 and 2009 in localities of interest. A partial result of the work is a comparison of the areas of treetops in aerial photographs on a representative area of one hectare. Part of the work are map appendixes showing all the obtained results.
