The thesis maps the occurence of sycamore and norway maple in area of the forest ecosystems sized 500 ha, which falls into the administration of Školní lesní podnik Masarykův les Křtiny, Polesí Bílovice nad Svitavou, Forestry section Jelence. The both maple species have been scattered in all of the four forest altitudinal zones and in the all of the five ecological tiers. norway maple has appeared mostly in the 1st. forest altitudinal zone and in the ecological tier enriched by humus. The largest number of sycamore has been in the 4th. forest altitudal zone and in the ecological tier enriched by water. The both maple species have been living in the most forest types of the defined location. The result is map data in ArcMap application in ArcGIS system. Both norway maple and sycamore have been found to resist biotic and abiotic harmful factors. Due to its resistence and great ecological amplitude, both maple species can be described as suitable for wide use in forestry in a wide range of natural conditions. As a source of reproductive material for Dyk‘s forest nursery of Školní lesní podnik Masarykův les Křtiny was designed 12 exceptionally high quality norway maple and 4 maple sycamores specimens as parents of families
