Old Growth Forests

Extended rotation of managed temperate hardwood forests is sometimes presumed to provide the important compositional and structural features of old-growth hardwood forests. However, the features of temperate hardwood old-growth and managed stands of extended rotation age have not been fully quantified and compared. This study compared quantitative parameters (density and volume of logs and snags, coarse woody debris volume (volume of logs + volume of snags), the proportion of hollow logs, basal area and tree, sapling, large seedling and small seedling densities), distributional patterns (diameter class and rot class of live trees, decay class of logs), and vascular plant species composition and diversity in old-growth and mature, managed sugar maple (Acer saccharum L.) - basswood (Tilia americana L.) and northern red oak (Quercus rubra L.) stands. Old-growth forests had higher coarse woody debris volumes and higher proportions of hollow logs, of live trees in large diameter classes, of logs in decay classes 1 and 2, and of live trees in rot classes 3-5 than the mature, managed forests. Old-growth and mature, managed forests did not differ significantly in plant species composition. These results indicate that, while older extended-rotation, managed stands can be very similar compositionally to old-growth forests, they differ quantitatively in structural features.

Decay State

The evaluation of volume, necromass, states of decay, solubility, and cellulose and lignin content in coarse woody debris (RLC) accumulated in an evergreen temperate forest of old-growth in the Puyehue National Park, South-Central Chile. Ten plots of 900 m2 each, were quantified for RLC (≥ 10 cm diameter). For necromass quantification was used a scale of five categories/states of decay, necromass (1 = lowest and 5 = highest degradation). 632 m3 ha-1 of deadwood (= 231,5 Mg ha-1 of necromass) was found, mainly represented by Nothofagus betuloides (95,2%). The wood with the most advanced state of decay (state 5) showed a greater solubility, increasing of 273,7 and 818,6 times more soluble than 1, for N. betuloides and S. conspicua, respectively. Cellulose content decreased to 91%, while the lignin increased 248% and 142% in wood decay of N. betuloides and S. conspicua, respectively. These results demonstrate the importance of RLC in the biogeochemistry of remote forest ecosystems of old-growth in Southern Chile.

Nothofagus Forests

The volume, biomass, and carbon and nitrogen content of coarse woody debris were measured on three 1-ha reference plots in old-growth Nothofagusfusca (Hook. f.) Oerst.–Nothofagusmenziesii (Hook. f.) Oerst. forest on the South Island of New Zealand. Two decay sequences for logs and one for standing dead trees (snags) were recognised from two-way indicator species analysis (TWINSPAN) of up to 30 variables related to physical characteristics and structural integrity. Wood volume (up to 800 m3•ha−1) and biomass were high (up to 300 Mg•ha−1), and the inside-out decay sequence from heartwood to sapwood was unusual compared with that of other temperate hardwood forests. Coarse woody debris represented significant carbon and nitrogen pools, with ca. 150 Mg•ha−1 and 370 kg•ha−1, respectively, in one stand. The coarse woody debris component of these broad-leaved evergreen hardwood forests was much higher than that reported for other temperate hardwood forests and approaches that of many northern hemisphere conifer forests. The large coarse woody debris pools are discussed in relation to live stand biomass, natural disturbances and tree mortality, and decomposition processes.
