In California and throughout the West everyone seems to be talking about global warming. Dominating the conversation are dire predictions about diminished water supplies that will result from shrinking snow pack in the West’s mountains. Conspicuously absent from the debate has been discussion of the impact of forest management on dry season water supply - “baseflow” in the lexicon of hydrologists.
The Western US may be the only place in the world where the connection between trees – or more precisely upland forests – and water supply is not recognized. Nobel Peace Prize winner Wangari Maathai’, whose organizations have planted millions of trees in Africa, claimed in an interview with Sierra Magazine that everyone knows that where there are trees there is also water. She was wrong. With a few notable exceptions, the Western US is in denial about the connection.
This denial is reflected in research programs and management plans being crafted to address global warming. The Forest Service, for example, has a massive global warming research program underway with a focus in California’s Sierra Nevada Mountains. One would think that the relationship between forest management and water supply would figure prominently in that research. But one would be wrong. The connection is not a focus for research and is barely even mentioned on the research programs web site.
