Research Abstract

We surveyed black spruce forests among permafrost types, i)forest on the continuous permafrost in NWT, ii)forest on the discontinuous permafrost in Interior Alaska, and iii) forest on the sporadic permafrost in NWT. Forest biomass accumulation, forest structure, and forest floor characteristics were surveyed. The deeper permafrost table depth, the larger forest biomass accumulation. Below-ground biomass estimation of black spruce forests in both Interior Alaska and NWT showed similarity formula.
