Description
This state is less degraded than State 2. Late-seral species are abundant. In riparian systems and ephemeral drainageways, channel incision is minimal and current floodplains are comparatively broad. In the case of playas, excavation to produce stock tanks is not evident.
Description
This state is more degraded than State 2. Late-seral species are either absent or present in reduced numbers. In riparian systems and ephemeral drainageways, channel incision is evident, and current floodplains are comparatively narrow. In the case of playas, excavation to produce stock tanks is evident.
Mechanism
This transition represents the lowering of the local water table by either excavation (in the case of playas) or incision (in the case of fluvial systems). Stream incision can result from a number of mechanisms including heavy animal or vehicle traffic, construction activities, and water diversion.
