Description: After initial clearing, parts of a fuelbreak on the Stanislaus Nationd Forest, central California, were planted to perennial grasses; other parts were not. After 5 years, a comparison between adjacent seeded sand unseeded strips shows that the perernnials had reduced the number of woody plant seedlings by a factor of 8, height of seedlings by 50 percent, and amount of mnud plant gound cover by 33 percent. Without perennial grass, the site would be reoccupied by woody plants in a very few years.

Keywords: fuel-break cover; perennial gass; woody plant cover; seedlhg repression; Stanislaus National Forest
