We studied forest floor and mineral soil carbon and nitrogen under six common European tree species in a common garden design replicated at six sites in Denmark. Three decades after planting the six tree species had different profiles in terms of litterfall, forest floor and mineral soil C and N attributes. Three groups were identified: (1) ash, maple and lime, (2) beech and oak, and (3) spruce. There were significant differences in forest floor and soil C and N contents and C/N ratios, also among the five deciduous tree species. The influence of tree species was most pronounced in the forest floor, where C and N contents increased in the order ash=lime=maple Author Affiliation: Forest & Landscape Denmark, University of Copenhagen, HA[cedilla]rsholm Kongevej 11, DK-2970 HA[cedilla]rsholm, Denmark Article History: Received 14 March 2007; Revised 21 August 2007; Accepted 21 August 2007
