Actually Clayton, your statement on carbon absorption is entirely incorrect and based on old, flawed science. It is now known that older forests and trees, store more carbon, more rapidly, than younger forests and trees.





It concerns me the way that one silvicultural system is pitted against another. Whether it is clearcutting or selection, both silvicultural systems are initiated for the purpose of growing new trees in place of trees harvested. The forest ecosystem is far too complex to simply limit the conversation to liking one way over another. The appropriate choice of silviculture depends on many factors: silvics of the trees, fire regime, wildlife habitat needs, geology, and much, much more.

The amount of carbon storage in the forest has nothing to do with choice of silviculture. As a hypothetical example, one part of a management objective is to harvest enough wood to build one house (approximately 13 mbf), depending on where you are in the state and the amount of standing volume. This could be accomplished by clearcutting 10 acres, or selecting 30 acres. From a carbon standpoint, the end result is the same amount of biomass removed from the forest. The difference is that the newly planted trees will grow faster over the next 80 years than the trees left by selection silviculture, absorbing far more additional carbon in the long run.

Please note that I have refrained from using the term selective logging, as this term means highgrading and is not a silvicultural system.

Thank you, Daly City, for taking an ethical stand on this vital issue. Without our forests we cannot breathe.

Here's to urban forests and backyards, which may be the saving habitat for honeybees, which are being chemically killed with herbicides in big agribusiness farms all over the country.
