Submodel
Description
Recognized by the need to mechanically treat the juniper woodland prior to initiating a prescribed burn. JSS phase with juniper dominance, Idaho fescue beneath tree canopies, bareground interspaces with a trace of Bluebunch wheatgrass and an increase in Sandberg’s bluegrass. Sagebrush is stressed and dying (JSS phase). As the juniper woodland matures, sagebrush and Bluebunch wheatgrass are eliminated and the potential for soil erosion increases (JW phase).
Submodel
Description
Recognized by the lack of bunchgrasses and sagebrush along with an understory dominated by cheatgrass with an overstory of either juniper or rabbitbrush.
Submodel
Description
Recognized by wind and water erosion and redistribution of soil. Dominated by annuals and shallow rooted grasses. Juniper or rabbitbrush may be the dominate overstory.
Abiotic factors control site resources and ecological function. Rehabilitation of this state may not be practical nor possible.
Submodel
Mechanism
With continued lack of fire, a fire proof juniper woodland is created. A biotic threshold has been crossed with Western Juniper controlling the site dynamics.
