Quantifying disturbance effects on vegetation carbon pools in mountain forests based on historical data

Effects of timber harvest on carbon pools in Ozark forests

We quantified and compared carbon (C) pools at a Missouri Ozark experimental forest 8 years after different harvest treatments. Total C pools were 182, 170, and 130 Mg C ha–1 for the control (no-harvest management; NHM), singletree, uneven-age management (UAM), and clearcut even-age management (EAM) stands, respectively. Harvesting reduced the live tree C pool by 31% in the UAM, 93% in EAM stan...

Disturbance Patterns in Southern Rocky Mountain Forests

Assessing naturalness in northern great lakes forests based on historical land-cover and vegetation changes.

The concept of naturalness was developed to assess to what degree landscapes represent a natural state. Protected areas are often regarded as the remnants of untouched landscapes although many landscapes commonly perceived as pristine have a long history of human impact. Here, we introduced a historical perspective into the concept of naturalness and the analysis of the effectiveness of protect...

Effects of vegetation type on microbial biomass carbon and nitrogen in subalpine mountain forest soils.

BACKGROUND/PURPOSE Microbial biomass plays an important role in nutrient transformation and conservation of forest and grassland ecosystems. The objective of this study was to determine the microbial biomass among three vegetation types in subalpine mountain forest soils of Taiwan. METHODS Tatachia is a typical high-altitude subalpine temperate forest ecosystem in Taiwan with an elevation of ...

Effects of moso bamboo encroachment into native, broad-leaved forests on soil carbon and nitrogen pools

Across southern China, Moso bamboo has been encroaching on most neighboring secondary broad-leaved forests and/or coniferous plantations, leading to the land cover changes that alter abiotic and biotic conditions. Little is known about how this conversion alters soil carbon (C) and nitrogen (N). We selected three sites, each with three plots arrayed along the bamboo encroachment pathway: moso b...
