The calculated data of phytomass and carbon (C) stock in the pools of stand, undergrowth, undergrowth phytomass, as well as in coarse woody debris (CWD) is presented. The obtained data of the stand phytomass and its C stock was analyzed by four different methods and the results were compared. In pine forests the stock of stand phytomass calculated based on the\u00a0regional data varies from 171 to 395 t\u00a0ha<sup>-1 <\/sup>and averages 254.2 t ha<sup>-1<\/sup>, whereas its C stock varies from 85 to 197 t C ha<sup>-1<\/sup> with an average value of 126.5 t C ha<sup>-1<\/sup>. The obtained results are by 7\u201310% lower than those obtained using other methods, which indicates the need for an additional research. Under the forest canopy, the undergrowth is represented mainly by pine and spruce and only sometimes with a minor participation of birch. The total undergrowth density varies from 0.2 to 4.9 thousand pcs ha<sup>-1<\/sup>. Undergrowth is often absent or represented by an insignificant amount of common rowan or grey alder. The total C stock of undergrowth and undergrowth fluctuates from 0.2 to 2.3 t C ha<sup>-1<\/sup>, that is only 0.57% of the phytomass C pool. The C stock in CWD in the studied pine forests varies from 9 to 60 m<sup>3<\/sup> ha<sup>-1<\/sup> and averages 40 m<sup>3<\/sup> ha<sup>-1<\/sup>. The largest share of CWD is represented by lying and standing deadwood of Scots pine of the 2nd decay class. The average C stock in CWD is 9.2 t C ha<sup>-1<\/sup> with a variation range from 1.7 to 14.3 t C ha<sup>-1<\/sup>. The study was conducted by the researchers of the Forest Research Institute of Karelian Research Centre RAS within the topic \u00abDevelopment of a system for land-based and remote monitoring of carbon pools and greenhouse gas flows in Russian Federation; providing for the creation of a data-registering system for recording data for climatically active substances and the carbon budget in forests and other terrestrial ecosystems\u00bb as part of the implementation of the most important innovative project of national importance (MIIPNI) \u00abUnified national system for monitoring climatically active substances\u00bb.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif;\"><strong><em>Keywords:<\/em><\/strong><em> MIIPNI, polygon \u00abKivach\u00bb, pine forests, phytomass, carbon, woody detritus, undergrowth, understory<\/em><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif;\"><em>\u00a0<\/em><\/span><\/p>\n<p style=\"text-align: center;\"><span style=\"font-family: 'times new roman', times, serif;\"><strong>REFERENCES<\/strong><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif;\">Alekseev G.
