Warming of the terrestrial biosphere due to the anthropogenic addition of carbon dioxide to the earth’s atmosphere is becoming a major focus of scientific inquiry. Predictions of the extent of this warming are hampered by uncertainty in the ability of the earth’s ecosystems to counteract this effect by sequestering carbon...
In 1998, forest vegetation was monitored for ozone injury on permanent plots in two Sierra Nevada national forests in California, at three locations in Mount Rainier National Park in Washington, and at 68 forest health monitoring (FHM) locations throughout Washington, Oregon, and California. This was the first year that extensive...

Forests of the Inland West have been experiencing forest health problems arising from over a hundred years of fire suppression, logging, grazing, and mismanagement.

Changes in forest ecosystem conditions in the region have prompted federal resource agencies to target the health of ecosystems in an effort to learn more about cause and effect relationships, develop plans for restoring healthy forest conditions, and communicate with citizens about treatment alternatives and potential outcomes. Because of the...
Selective suppression of crown and root sprouting of
non-coniferous cover are the keys to effective forest
vegetation management. This study 1) develops insight into
mechanisms of controlling root suckering and top regrowth of
bear clover (Chamaebatia foliolosa), and develops a broad
data base for controlling broad groups of vegetation
chemically....
