Book Description
The Forest Regeneration Manual presents state-of-the-art information about current regeneration practices for southern pines in the United States. Over 1.2 billion seedlings of five major species -- loblolly, slash, longleaf, sand, and shortleaf -- are planted each year. In 22 chapters, the Manual details fundamental steps in establishing successful young pine plantations: regeneration planning, including economic and legal aspects; regeneration harvest methods; propagation by seed and vegetative techniques; bareroot and container seedling culturing in the nursery; measures of seedling quality; site potential; -- environment, associated vegetation, soils; matching species to sites; site preparation -- mechanical and chemical methods, fire, fertilization; seedling handling before planting; planting practices and measures of regeneration success; promoting early plantation growth and management of competing vegetation, insects, disease, and wildlife.

Book Description
ing damage ranged from odor. to general visual appearance. Attributes of seedling quality are categorized as either to cutting buds. to scraping bark to detect dead cambium. performance attributes (RGP. frost hardiness. stress resistance) One nursery reported using frost hardiness as an indicator of or material attributes (bud dormancy. water relations. nutrition. when to begin fall lifting. but none reported using it as an morphology). Performance attributes are assessed by placing indicator of seedling quality before shipping stock to customers. samples of seedlings into specified controlled environments and evaluating their responses. Although some effective short 23.4.3 Stress resistance cut procedures are being developed. performance tests tend Only three nurseries measure stress resistance. They use to be time consuming; however, they produce results on whole the services of Oregon State University and the test methods plant responses which are often closely correlated with field described in 23.2.3. One nursery reported that results of stress performance. Material attributes. on the other hand. reflect tests did not agree well with results of RGP tests and that RGP only individual aspects of seedling makeup and are often correlated better with seedling survival in the field. Most stress poorly correlated with performance. tests are conducted for reforestation personnel rather than for Bud dormancy status seems to be correlated. at least nurseries.

Book Description
The Tree Faller’s Manual is an essential handbook for forest operators and others who need to fell trees manually using a hand-held chainsaw. This manual builds on the information provided by the Chainsaw Operator’s Manual. Tree felling is a high risk activity. Many fatalities and serious injuries have occurred as a result of being struck by falling trees, dislodged tree limbs or other dangers in the area. Most of these accidents are caused by using unsafe felling techniques and not following safe work procedures. This manual will guide the faller to safer work techniques. The manual is based on the national competency standards for the forest and forest products industry where tree-felling is covered using three categories: basic, intermediate and advanced. Basic tree felling applies to trees that are relatively small, with a single stem and no defects. Intermediate tree felling covers trees with single or multiple stems, limited defects, and lean and weight distribution that can be adapted to felling direction. Advanced tree felling applies to larger and more complex trees and includes trees deemed to be more hazardous. Workplace safety, risk assessment and site preparation are included along with the theory, techniques and tools for each of the tree-felling categories.
