Book Description
Excerpt from Predicting Regeneration Establishment With the Prognosis Model Forests of Idaho and Montana are quite diverse. Environmental conditions support forest types ranging from dry ponderosa pine (pinus ponderosa) for ests, to near-rain forests dominated by western redcedar (thuja plicata) and western hemlock (tsuga heterophylla), to high-elevation subalpine fir (abies lasiocarpa) and Whitebark pine (pinus albicaulis) forests where the gron season is short. These forests are highly valued for timber, wildlife, water, grazing, recreation, biological diversity, and esthetics. Management often involves the manipulation of conifers through timber harvests, natural and artificial regeneration, site preparation, weedings, and thinnings; control of competing vegetation such as shrubs, forbs, and grasses; and control of insects, diseases, and wildfires. Manipulation of for ests changes the course of secondary succession which, in turn, affects the future of these ecosystems. Land managers need to know how their actions affect the course of second ary succession. One particularly important effect is the regeneration of coni fers following timber harvest. Can cutover areas be regenerated in a timely manner to desirable species having acceptable growth rates? Which of sev eral alternative silvicultural prescriptions should be used to reach desired future conditions? Land managers compare alternative silvicultural prescriptions to determine which one best meets management objectives. These comparisons need to be quantified in a biologically meaningful and statistically sound manner. Fortunately, the necessary information is available to quantify the regener ation process in much of the Western United States.

Book Description
Conifer establishment following regeneration treatments can be predicted in the grand fir-cedar-hemlock ecosystem of the northern Rocky Mountains. Alternative treatments can be evaluated by a model that represents regeneration establishment and early development. This model is designed to be used with the Intermountain Forest and Range Experiment Station's Prognosis Model (Stage 1973). Mathematical equations representing most harvest and site preparation methods common in the northern Rocky Mountains predict the probability of stocking, trees per acre, species composition, and tree heights between 3 to 20 years following treatment. These relations were derived from a stratified random sample of areas managed by conventional harvest and site preparation treatments. However, the analysis and modeling methods are structured to permit combinations of treatments within a stand that might differ from past practices.
