Old Growth

Room for Improvement

just making some room for improvement

VicForests has a snowball’s hope in hell of gaining the green tick of approval from the Forest Stewardship Council (FSC), an international wood certification body.

It had a preliminary audit carried out on its logging management and it failed dismally. This didn’t stop it from claiming in a media release that the auditors recognised the wonderful job they do (!?)

Carbon accumulation in large trees

Thursday, March 27, 2014

This research counters the logging industry argument that a young post-logging regrowth forest (and plantations) accumulate more carbon than a natural mature forest. It highlights the importance of old large trees in the carbon cycle.

New policies for old trees - averting a global crisis in a keystone ecological structure

Wednesday, March 5, 2014

Large old trees are critical organisms and ecological structures in forests, woodlands, savannas, and agricultural and urban environments. They play many essential ecological roles ranging from the storage of large amounts of carbon to the provision of key habitats for wildlife. Some of these roles cannot be replaced by other structures. Large old trees are disproportionately vulnerable to loss in many ecosystems worldwide as a result of accelerated rates of mortality, impaired recruitment, or both.

Rate of tree carbon accumulation increases continuously with tree size

Wednesday, January 15, 2014

Forests are major components of the global carbon cycle, providing substantial feedback to atmospheric greenhouse gas concentrations1. Our ability to understand and predict changes in the forest carbon cycle—particularly net primary productivity and carbon storage—increasingly relies on models that represent biological processes across several scales of biological organization, from tree leaves to forest stands2, 3.
