The aim of graduation thesis was to introduce the assessment of environmental impacts, environmental legalization and other strategic documents, define principles and goals for environment protection and explain terms connected with environment. Beside theoretic part about assessment of environmental impacts, we did also practical work on golf course Arboretum Volčji Potok. We carried out soil and water sampling and made maps of habitat types. We made maps of habitat types for year 1995 and 2006. This one-decade difference allowed us to evaluate impacts on environment on golf course and its surroundings.
