Annual runoff scenarios for drained Sphagnum (SP) and Carex (CP) peat-dominated peatland areas with varying tree stand stem volumes during the first year after DNM as simulated by the FEMMA model (Koivusalo et al. 2008). The weather input data are as in 2009 in southern (60°27′N; 24°57′E) and northern (64°43′N; 26°0′E) Finland. Pre-DNM and post-DNM ditch depths are 25 and 100 cm, respectively, and ditch spacing is 40 m. The bulk density and hydraulic conductivity are 0.075 g cm⁻³ and 2.12 cm h⁻¹ in SP and 0.156 g cm⁻³ and 0.58 cm h⁻¹ in CP, respectively
