Short-Term Influence of Tank Tracks on vegetation and Microphytic Crusts in Shrubsteppe Habitat

摘要

I examined vegetation and microphytic crust cover on two sites in burned and two sites in unburned big sagebrush (Artemisia tridentata Nutt.) habitat within the Idaho Army National Guard Orchard Training Area in South- Western Idaho. The purose of this study was to determine The short-term (1-2 years) influence of tank tracks on vegeta- Tion and microphytic crusts in shrubsteppe habitat. The two Types of tank tracks studied were divots (area where one Track has been stopped or slowed to make a sharp turn) and Strigth-line tracks.
