“…Slash reduced moisture loss and was decidedly beneficial in aiding establishment of ponderosa pine seedlings (Pearson and Marsh 1935). Scattering slash rather than burning has been suggested as a measure to conserve soil moisture on lighttextured and shallow stony soils (Lutz andChandler 1947, Pearson andMarsh 1935). Shade cast by logs, stumps, rocks, and other nonliving material reduces water loss and thereby favors early seed germination and survival of young seedlings (Heidmann 1963b, Schubert and Adams 1971.…”

“…Treatment of ponderosa pine seedling foliage with transpiration retardants had no effect when soil moisture was limiting (Fowells and Schubert 1955, Mowat 1961, Rietveld andHeidmann 1969). Even a three-rock mulch around the base of newly planted trees had no real beneficial effect on pines where competing vegetation had been eliminated (Heidmann 1963b).…”

Describes the status of our knowledge of ponderosa pine silviculture in the southwestern States of Arizona, Colorado, New Mexico, and Utah. Economic value, impact on other uses, and the timber resource are discussed first, followed by ecological background, site quality, growth and yield, and silviculture and management. Relevant literature is discussed along with observations, experience, and results of unpublished research. Treatise is intended to serve as a reference tool for guidance in making management decisions and prescribing silvicultural treatments.Research needs are also considered.

Successful plantations result when healthy trees are planted carefully on well-prepared sites from which cattle are excluded (Heidmann 1963, Schubert et al 1970, Schubert 1974. Regeneration by natural or artificial seeding, on the other hand, generally has been a failure.…”

Results from many studies of ponderosa pine regenerationseeding, planting, and naturalover the past 15 yr on several areas on and near the Beaver Creek watershed in central Arizona indicate that seeding offers little hope of success. The failure of direct seeding is attributed to seasonal drought intensified by clay soils and competing vegetation. Tree planting has been consistently more successful. Although this report discusses research involving pesticides, such research does not imply that the pesticide has been registered or recommended for the use studied. Registration is necessary before any pesticide can be recommended. If not handled or applied properly, pesticides can be injurious to humans, domestic animals, desirable plants, fish, and wildlife. Always read and follow thê ;3*6s4**/J^d irections on the pesticide container.

“…Some of the obstacles to obtaining natural or artificial reestablishment of ponderosa pine seedlings in the Southwest are: ( 1) impairment of nutrient status and structure of soil brought about by fire; (2) greater extremes of temperature and wind in large open areas; ( 3) low . soil-moisture availability, especially during the spring months of the year due to soil differences and climatic extremes; ( 4) competition for moisture and nutrients with low brush and forb vegetation occupying the burn sites; or any combination of these factors (Pearson 1950, Gaines and Shaw 1958, Heidemann 1963, Larson 1961.…”

Plant bioassays, with lettuce and ponderosa pine seedlings as indicator plants, and chemical analyses were used to investigate differences in macronutrient availability in soils from areas of different wildfire burn histories. Soils originating from the same parent material were collected from unburned areas consisting of a large control area, having no known history of burning, and two small relict unburned areas, located within two large areas that had been burned over by a severe wildfire at different times in their history. The vegetation, litter, and soil profiles of the relict areas suggested that the soils of these areas were very similar to those of the control area, which indicated that the soils of all three areas were alike before the advent of wildfire into the two burned-over areas. The assays essentially substantiated this conclusion. Soils were collected from the same three areas, with the difference that two were from central locations in the large areas burned over by wildfire. Thus representative soils were obtained from areas with no known history of burning, an old burn (over 12 years old), and a recent burn (3 years old). Assays indicated that nutrient availability in these soils was completely different, and this difference apparently was due to the effect of wildfire on the soils. Fire, through its effect on soil nutrients, could thus exert a profound effect on the nature and growth of the surface vegetation. 1
