    Cultivation in the ponderosa pine zone of Colorado has, in many instances, been unprofitable because of the uncertainty of crops and eventual loss of soil fertility. Consequently, many areas have been abandoned, and natural revegetation has resulted in the presence of all stages of the secondary succession, from the initial invasion to almost complete return to the original subclimax grassland community.
