Description
This reference state is developed and characterized using available vegetation models, most notably United States Department of Agriculture - Soil Conservation Service range surveys from the 1980s (SCS, 1984; Swanson et al., 1985).
The reference state describes two distinct vegetative communities. One post-burn community is recognized. Exposure to wind and low annual temperatures restrict vegetation height.
There is no indication of an alternate grazing state on this site. Targeted data collection may be able to address whether grazing or browsing in the reference state result in an alternate state.
Submodel
Description
The reference state describes solifluction lobe features. There are two distinct vegetative communities on this feature. Exposure to wind and low annual temperatures restrict vegetation height.
Submodel
Mechanism
Solifluction lobes are created by the downward slide of soil and overlying vegetation atop a substrate of permafrost and seasonal melt.

Briefcase
Add ecological sites and Major Land Resource Areas to your briefcase by clicking on the briefcase (
) icon wherever it occurs. Drag and drop items to reorder. Cookies are used to store briefcase items between browsing sessions. Because of this, the number of items that can be added to your briefcase is limited, and briefcase items added on one device and browser cannot be accessed from another device or browser. Users who do not wish to place cookies on their devices should not use the briefcase tool. Briefcase cookies serve no other purpose than described here and are deleted whenever browsing history is cleared.
