Annex 2 Tree carbon sequestration (t CO2-eq. yr–1) in Ostrovskoe in 2009 and in the baseline and project scenario. In order to perform calculations the area was stratified into 43 subareas. The sequestration rate is calculated using the proportion of tree species according to the State Forest Inventory (2008) and the respective sequestration rate (Annex 1). For the recently burnt subareas 20 and 30 an increase in stand density is assumed for 2039. For subareas 34–39 and 41, in 2039 a yield class of V and a proportion of Betula of 100% is assumed (for the not extracted subarea 39: 60% Betula, 40% Pinus). For the project scenario, it is assumed that each subarea will have yield class conditions one class higher (i.e. lower quality) than in 2009
