Forestry

Forestry is the science, art, and craft of creating, managing, using, conserving, and restoring forests and associated resources to meet desired goals, needs, and values for human benefit. Forestry is practiced in plantations and natural stands. The main goal of forestry is to create and implement systems that manage forests to provide environmental supplies and services. The challenge of forestry is to create systems that are socially accepted while sustaining the resource and any other resources that might be affected.

Forests cover approximately 9.4 percent of the Earth's surface (or 30 percent of total land area), though they once covered much more (about 50 percent of total land area), in many different regions and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the biosphere. Forests are present in many biomes:

Selected article

Sunlight shining through redwoods in Muir Woods, California
Sequoia sempervirens includes the tallest trees on Earth, reaching up to 379 feet (115.5 m) in height. It is an evergreen, long-lived, monoecious tree living 1200–1800 years or more. This species includes the tallest trees living now on Earth, reaching up to 379 feet (115.5 m) in height (without the roots) and up to 26 feet (7.9 m) in diameter at breast height. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated 2,100,000 acres (8,500 km2) along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner of coastal Oregon within the United States. An estimated 95% or more of the original old-growth redwood forest has been cut down, due to its excellent properties for use as lumber in construction.


Selected biography

Heinrich Cotta
Heinrich Cotta, German silviculturist and founder of the Royal Saxon Academy of Forestry, is known as a pioneer of scientific forestry. Cotta was a pioneer of modern forestry, and was a catalyst concerning the transition from "timber production" to forestry as a scientific discipline. He was interested in all aspects of forestry, including studies involving long-term seeding, establishment of forested areas, and tree-cutting based on mathematic practices. Cotta's methodology was based on a geometric survey of the forest, where calculations of the wood mass of individual trees as well as the yield of the entire forested region were made. By way of these calculations an estimate for the monetary worth of a forest could be assessed. In 1804 Cotta was the first to suggest the concept of a "volume table", which was a chart that was introduced decades later to aid in the estimation of standing timber volume.
