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.

Shortcut:

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:

The Daintree Rainforest near Cairns, in Queensland, Australia
Rainforests are forests characterized by high rainfall, with definitions based on a minimum normal annual rainfall of 1750-2000 mm (68-78 inches). The monsoon trough, alternatively known as the intertropical convergence zone, plays a significant role in creating the climatic conditions necessary for the Earth's tropical rainforests.

Around 40% to 75% of all biotic species are indigenous to the rainforests. It has been estimated that there may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests are also responsible for 28% of the world's oxygen turnover, sometimes misnamed oxygen production, processing it through photosynthesis from carbon dioxide and consuming it through respiration.

The undergrowth in some areas of a rainforest can be restricted by poor penetration of sunlight to ground level. If the leaf canopy is destroyed or thinned, the ground beneath is soon colonized by a dense, tangled growth of vines, shrubs and small trees, called a jungle[citation needed]. There are two types of rainforest, tropical rainforest and temperate rainforest.

Selected biography

Georg Ludwig Hartig
Georg Ludwig Hartig (September 2, 1764 – February 2, 1837) was a German forester. In 1786, Hartwig was appointed as Manager of Forests for the Prince of Solms-Braunfels at Hungen, in the Wetterau, Hesse. While in this position, he founded a school for the teaching of forestry, one of the first dedicated schools of forestry in Europe. In 1806, Hartig went to Stuttgart as Chief Inspector of Forests. Five years later, in 1811, he was called to Berlin in a similar capacity. There he reestablished his school once again, succeeding in connecting it with the University of Berlin.
