Description

This state represents the natural range of variability under pristine conditions. This state is dominated by Rocky Mountain ponderosa pine with traces of Rocky Mountain juniper, singleleaf pinyon pine and white fir in the canopy. Primary natural disturbance mechanisms affecting this ecological site are wildfire and periodic drought. Timing of weather events combined with disturbance events determines plant community dynamics. Infrequent, yet periodic wildfire is presumed to be a natural factor influencing the understory of mature ponderosa pine forests. Increased mortality following drought is likely caused by a combination of drought, insect attack and disease.
