Abstract

The mass of carbon (C) in standing trees on 1.5 M ha of Tasmanian State forest was 163 Tg C, with 139 Tg in eucalypt forest. The highest C densities occurred in the tallest, highest crown cover, mature, wet eucalypt forest, representing 0.2% by area containing only 1.3 Tg C. Shorter mature forests with lower crown cover contained 21–68% of this C density. Rainforests and forests containing regrowth or silvicultural regeneration components also contained lower C densities. Landscape-level C saturation of Tasmanian State forest could only be achieved when all forest was simultaneously mature eucalypt forest. This would sequester an additional 93 Tg C into trees, but would require fire to convert existing mixed forest and rainforest to eucalypt forest, and subsequent estate wildfire prevention while eucalypt forests mature and the prevention of eucalypt forests progressing to less C-dense rainforest. Theoretical C saturation at the landscape level is therefore ecologically impossible.
