Figure 2: Annual rings in the cross-section of the trunk of a conifer. The volume of wood laid down by the tree each year dictates its rate of carbon sequestration.
If you really want to analyse something as complex as carbon sequestration in trees (which is the focus of this short article) – and the value of trees and forests as stores of carbon, there is no avoiding some number-crunching.

Water once per week, one inch per week, under the entire branch spread, in the absence of rain, May through November. Either rainfall or your watering should equal the one inch per week. Put out a sprinkler and a straight sided soup can or rain gauge and measure one inch per week.
To the extent possible recycle fallen leaves back into the soil around the trees and maintain mulch around the trees to a radius of at least 3-5 feet. Keep mulch off trunks. Use a coarse textured mulch. Avoid triple shredded mulch. Aged arborist wood chips, mulched and composted leaves, pine bark, and pine straw are all good. Very finely ground mulches such as triple ground hardwood mulch are not beneficial and may inhibit moisture and oxygen exchange.

I got a Facebook message early this week from a friend in Sacramento CA that said after over 200 days with no rain, she got 4.83 inches in a 24-hour period from the latest extreme rainfall that occurred over northern California. Others have reported up to a foot of rain in three days. If you follow the news, you may have heard the term “atmospheric river” used to describe the torrential rains and flooding that have occurred this week in San Francisco and other parts of Northern California. In this post, I want to explain what atmospheric rivers are and how they affect rain climatology in the Western U.S. as well as other parts of the United States and the world.
