INTERACTIVE INFLUENCES OF WILDFIRE AND NONNATIVE SPECIES ON PLANT COMMUNITY SUCCESSION IN HAWAII VOLCANOES
Vegetation response to prescribed fire in mountain big sagebrush ecosystems at Lava Beds National Monument, California

Creator:

Ellsworth, Lisa M.

Abstract:

Anthropogenic land use alterations such as livestock grazing and fire suppression have greatly altered sagebrush grasslands of the Great Basin, facilitating invasion of exotic annuals, increases in woody species, and losses of native species. Much of the current research surrounding wildland and prescribed fire in sagebrush dominated ecosystems has focused...
