Creator:

Schantz, Merilynn C.

Abstract:

Biological plant invasions are diminishing the ecological integrity and function of ecosystems worldwide. A primary example of this is in the Great Basin of the United States, where invasive annual grasses, like cheatgrass (Bromus tectorum L.) and medusahead (Taeniatherum caput-medusae L.

Establishing native plants in crested wheatgrass stands using successional management

Creator:
