Outline of Research at the Start

永久凍土上に成立する北方林の炭素蓄積機能が、森林更新を起こすきっかけのイベントの一つである森林火災の前後、特に永久凍土面の火災後の沈下と数十年後の再上昇過程で、どのように変化するかを明らかにする。

Outline of Final Research Achievements

We estimated the effects of the vegetation recovery after disastrous forest fire (occurred in 2004) on permafrost table depth and aboveground forest biomass accumulation, in Interior Alaska. Before forest fire, permafrost table depth was about 40 to 70 cm at the north-facing slope dominated by mature black spruce (Picea mariana). Permafrost table subsided to 160 cm depth after 1 year (in 2005), and there is no obvious permafrost table recovery after 20 years (in 2024), with 150±35cm. Aboveground biomass at the burnt black spruce stands recovered at 33 tons/ha after 20years, which is almost 60 % biomass accumulation of mature black spruce stands (about 100-year-old stands). According to census data during 2022 and 2024, growth rate of aboveground biomass was 4 tons/ha/yr. This is equivalent to 2 tons carbon/ha/yr.

Academic Significance and Societal Importance of the Research Achievements

永久凍土面の沈下と再上昇が引き起こす森林構造の変化過程の定量化は、気候変動下における森林火災の頻発と大規模化によって引き起こされる凍土融解が、北方林生態系の炭素蓄積機能にどのように影響するかという将来予測に役立つ。また、植生回復が進んでも永久凍土の再凍結に至らない気候条件の変化が危惧されている昨今、北方林生態系が二酸化炭素の放出側に転じた場合の炭素収支予測の基礎データとなる。
