Inventory data of the oxidizable carbon content in forest soils up to 30 cm depth (COX30) were used to predict the likely change of soil carbon content under warming. Sampling points were located across all altitudinal zones and forest ecological series of the Czech Republic. The COX30 content increases with altitude, at low altitudes negligibly, above 600 m a.s.l. rapidly, however, above 1050 m a.s.l., it decreases. By means of the linear stochastic model created, different sensitivities of carbon release to warming was found according to different altitude levels. The biggest contributor to the total COX30 loss would be altitudes of 700 –900 m a.s.l. Using low, middle and high emission scenarios in climatic model HadCM3, the losses in the CR are expected to be ca. 7.8%, 10.7% and 12.5%, respectively, of the present forest soil carbon stock.
