- Abstract
- After initial clearing, parts of a fuel-break on the Stanislaus National Forest, central California, were planted to perennial grasses; other parts were not. After 5 years, a comparison between adjacent seeded and unseeded strips shows that the perennials had reduced the number of woody plant seedlings by a factor of 8, height of seedlings by 50 percent, and amount of annual plant ground cover by 33 percent. Without perennial grass, the site would be reoccupied by woody plants in a very few years.
