Valutation of ecosystem services provided by habitat on the basis of biodiversity characteristics and the rate and sustainability of selected ecosystem functions
Cudlín, Pavel ; Prokopová, Marcela ; Cudlín, O.
Increasing human impacts on ecosystems result in a continuous decrease in biodiversity; scientists try to estimate the consequences in ecosystem functioning and ecosystem service (ES) provision. A suitable space framework to study this relationship could be the habitat and its relative value expressed by the monetary valuation of a selected fi nal ES. A cross connection of the methods for ecosystem functioning assessment with biodiversity valuation of habitats would enable an estimation of the role of biodiversity in ES provision. It is necessary to identify not only present functioning, described by eff ect traits, but also its sustainability under global environmental change conditions, described by response traits. Th is approach could reveal the resilience and adaptation potential of present habitats to environmental change and subsequently potential changes in ES provision.

Energy-Water-Vegetation Based Environmental Accounting of Ecosystem Services and Stocks
Seják, J. ; Pokorný, J. ; Cudlín, Pavel ; Burešová, Renata ; Prokopová, Marcela
Human societies and their economies decisively depend on the life supporting functions and services of earth’s ecosystems (MEA 2005). Natural ecosystems protect against harmful cosmic radiation, continually control the composition of atmosphere, produce fertile soil and biomass, clear air and water, mitigate climate extremes, maintain biodiversity, decompose organic waste etc.

Efekt různých měřítek a podrobností mapování na hodnocení krajiny
Prokopová, Marcela ; Burešová, Renata ; Seják, J. ; Cudlín, Pavel
The main purpose of this paper is examining the utilization of various mapping data for biotope evaluation by BVM (biotope valuation method, modified from Hessian method). The evaluation of landscape segments of different size was performed and compared while using mapping data of different scale (Corine LC and NATURA 2000 mapping). The result shows advisable combinations of map extent and mapping data for biotope evaluation in order to maximize the effectivity and leave the high information value.

Biotopes evaluation and assessing using Natura 2000 mapping system
Cudlín, Pavel ; Kučera, Tomáš ; Prokopová, Marcela ; Francírková, Tereza ; Burešová, Renata ; Smrž, T. ; Boucníková, Eva ; Hellebrandová, K. ; Petříček, V. ; Dejmal, I. ; Seják, J.
For creating price maps, data from NATURA 2000 mapping system are useful and they give topographically more accurate data than CORINE Land Cover. Nevertheless the total price differed very slightly, probably because of the studied area was large enough. Individual evaluation changed the total value mainly in case of natural and close to nature biotopes. The total value of the whole area was changed by only approximately 2 or 5% (according to used procedure of data transfer). It means that individual evaluation could be ignored for price map formation, in the last resort.
