Target ecosystem state
Select a state
Description
This state represents the most ecologically stable conditions in terms of resistance to erosion. Moreover, this state has the highest potential for productivity and plant diversity.
Submodel
Description
The overstory of this state is dominated by twoneedle piñon.
Characteristics and indicators
Overstory dominated by twoneedle piñon.
Dominant plant species
twoneedle pinyon (Pinus edulis), tree
Submodel
Description
This state resembles State 2, except that PIPO is a significant component of the overstory.
Dominant plant species
ponderosa pine (Pinus ponderosa), tree
Submodel
Mechanism
Increase in overstory, loss of understory production due to change in fire regime caused by fire suppression and overgrazing. Loss of understory increases fire suppression and erosion.
Mechanism
Increase in overstory, loss of understory production due to change in fire regime caused by fire suppression and overgrazing. Loss of understory increases fire suppression and erosion. A few wet years in which PIPO are established.
Mechanism
Restoration of herbaceous understory component through thinning of pinon, cutting of ponderosa, possibly seeding, and proper grazing management.
