Abstract We investigated N2O and CH4 fluxes from soils of Quercus ilex, Quercus pyrenaica and Pinus sylvestris stands located in the surrounding area of Madrid (Spain). The fluxes were measured for 18 months from both mature stands and post fire stands using the static chamber technique. Simultaneously with gas fluxes, soil temperature, soil water content, soil C and soil N were measured in the stands. Nitrous oxide fluxes ranged from -11.43 to 8.34 lg N2O N m-2 h-1 in Q.ilex, -7.74 to 13.52 lg N2O N m-2 h-1 in Q. pyrenaica and -28.17 to 21.89 lg N2O N m-2 h-1 in P. sylvestris. Fluxes of CH4 ranged from -8.12 to 4.11 lg CH4 C m-2 h-1 in Q.ilex, -7.74 to 3.0 lg CH4 C
