ABSTRACT
The presented contribution deals with the former ash pond from coal power plant study in the Třinec city which is one of the most important industrial cities in the Czech Republic. The paper describes results of research focused on long-term biotopes mapping of this area. For more accurate statement of time changes of vegetation and ecological value assessment were used aerial orthophotomaps of 1958, 2000, 2003, 2006 and 2009 years (1:7500). Scientific benefit of the contribution is to draw attention to the possibility using today’s air orthophotomaps and introduce a method for evaluating the ecological and monetary value of habitats which is based on the method of Hessian for financial statements of environmental damage area. Recently, Hessian method is also recommended by the European Commission White Paper of Environmental Liability, for assessment of damage to biodiversity. The results of this research refer to the highest ecological value for the year 1958 ie. before building the pond and lowest value for the year 1970 when the pond was fully functional and its area is occupied almost with 80% of the total surveyed area and 20% were terraces with spontaneous vegetation.
