Summary/Abstract: The main aim of this paper is to use the InVEST software (model Pollinator Abudance: Crop Pollination) for the ecosystem services assessment in the territory of Nitra town and adjacent municipalities (Slovakia). At the beginning, we clarify the concept of ecosystem services and the basics of InVEST software. Then, on the basis of the landscape structure map (for year 2016) we demonstrate how InVEST works – we use the pollination model for detecting the preconditions for occurrence of wild bees and bumble bees in the landscape. We analyse occurrence of wild pollinators in the research area in regards to possibilities of their nesting and accessibility to flower sources. The analyses are based on GIS raster layer of landscape structure and related data - information about basic features of secondary landscape structure (which are important for behaviour of wild bees and bumble bees) and information about pollinator species occurring in the research area. The outcomes of conducted analysis are spatial and narrative assessment of relative potential of wild pollinators’ occurrence in the research area. This information could be useful e.g. for agriculture optimizing and landscape management.
