Old-growth forests as global carbon sinks

Nature, 2008
Old-growth forests remove carbon dioxide from the atmosphere at rates that vary with climate and nitrogen deposition. The sequestered carbon dioxide is stored in live woody tissues and slowly decomposing organic matter in litter and soil. Old-growth forests therefore serve as a global carbon dioxide sink, but they are not protected by international ...

High-carbon primary forests as conservation targets in Ontario, Canada

Frontiers in Forests and Global Change
Ontario’s forests are changing rapidly under the pressure of industrial logging, coupled with the effects of climate change, which is facilitating increased wildfires. The reduction of mature and old-growth forests negatively affects ecosystem functions,

Burn to Save, or Save to Burn? Management May Be Key to Conservation of an Iconic Old-Growth Stand in California, USA

Fire
Seasonally dry mature and old-growth (MOG) forests in the western USA face increasing threats from catastrophic wildfire and drought due to historical fire exclusion and climate change.

Investigating LiDAR Metrics for Old-Growth Beech- and Spruce-Dominated Forest Identification in Central Europe

Remote Sensing
Old-growth forests are essential for maintaining biodiversity, as they are formed by the complexity of diverse forest structures, such as broad variations in tree height and diameter (DBH) and conditions of living and dead trees, leading to various ...

A culture of conservation: How an ancient forest plantation turned into an old‐growth forest reserve – The story of the Wamulin forest

People and Nature, 2021
The global expansion of forest plantations at the expense of natural forests, especially old‐growth forests, raises concerns about habitat loss and a decline in ecosystem services.

Smallholder agriculture results in stable forest cover in riverine Amazonia

Environmental Research Letters, 2021
Recent studies point to a rapid increase in small-scale deforestation in Amazonia. Where people live along the rivers of the basin, customary shifting cultivation creates a zone of secondary forest, orchards and crop fields around communities in what was

A Rapid Method to Assess, Map, and Develop Standards for Old Growth: Catchacoma Primary Hemlock Forest, Ontario, Canada

Wild
All eastern hemlock-dominated forests in Ontario could be gone by 2075 given current trends, which demands rapid assessment to locate these endangered ecosystems.

Effects of forest management on native bee biodiversity under the tallest trees in the world

Ecology and Evolution, 2023
It is not clear if mature secondary growth coniferous forests can support similar pollinator communities as old growth coniferous forests, or how active management (e.g., retention forestry) in mature secondary growth forests may affect pollinator ...

The carbon cycle in the old-growth forests [PDF]

Forest@ - Rivista di Selvicoltura ed Ecologia Forestale, 2008
According to a recent paper published in Nature (Luyssaert et al. 2008) the old-growth forests remove carbon dioxide from the atmosphere and should be considered an important carbon sink at the planetary level. This finding is discussed both in relation to the traditional hypothesis that considered the old-growth forests "neutral" in the carbon balance,
