Modelling forest carbon stock changes as affected by harvest and natural disturbances. I. Comparison with countries’ estimates for forest management

Table 2 Overview of countries with natural disturbance events simulated by the CBM (F fire, S storms and ice sleets, I insect attacks), with information on input data used for storms (country data, National Inventory Reports, NIR or the FORESTORMS database [31] and the average annual burned area

^aAverage volume affected by storms, ice and insects between 2000–2012, as reported by the input data used by CBM. The interannual variations of these disturbances can vary considerably among countries (i.e., in many cases disturbances are concentrated in few big events). In some cases, further damages were considered before 2000
^bAverage area affected by fires between 2000–2012, mainly based on the data reported by National Inventory Reports*
