Carbon sequestration in forest plantations in Iceland ARNÓR SNORRASON and
The main goal of the current project was to develop methodology for determining the total organic carbon stocks (C-stocks) at afforestation sites, and to estimate their mean annual carbon sequestration (C-se-questration) by stock-change method. This method involves a comparison between C-stocks on a...
