“…Where dead shade is not available, an upright shingle or similar object may be firmly planted in or very close to the planting hole on the south side of the seedling (Ronco 1967 Einspahr 1962, Einspahr 1959), as have techniques for growing aspen directly or indirectly from root cuttings (Benson and Schwalbach 1970, Farmer 1963, Starr 1971, Zufa 1971. Genetic differences between aspen clones may provide real opportunities for the selection of genotypes with superior autumn coloration, growth, or disease resistance characteristics (Egeberg 1963, Graham et al 1963, Rudolf andPatton 1966, Wall 1971).…”

GENERAL DESCRIPTION OF THE MIXED CONIFERS Mixed conifer forests occupy sites more moist than those usually occupied by pure stands of ponderosa pine. 2 Pinyon-juniper woodlands and the variable mixtures of Chihuahua pine, Apache pine, and evergreen shrubs are not mixed conifer forests within this definition. The common overstory species in mixed conifer forests are Douglas-fir, ponderosa pine, white fir, Engelmann spruce, aspen, southwestern white pine, blue spruce, and corkbark fir, often in more or less that order of abundance.
