| 3830793794 | Deforestation | The removal of forest stands by cutting and burning to provide land for agricultural purposes, residential or industrial building sites, roads, etc., or by harvesting the trees for building materials or fuel. | 0 | |
| 3830793795 | Old-Growth Factors | A nontechnical term often used to mean a virgin forest (one never cut) but also used to mean a forest that has been undisturbed for a long, but usually unspecified, time. | 1 | |
| 3830795572 | Tropical Forests | Are found between the Tropic of Cancer and Tropic of Capricorn. Tropical forests are in a climate where there is no winter or frost so the leaves stay on the trees year-round. Tropical forests have only two seasons - wet and dry | 2 | |
| 3830797062 | Selective Cutting | In timber harvesting, the practice of cutting some, but not all, trees, leaving some on the site. There are many kinds of selective cutting. Sometimes the biggest trees with the largest market value are cut, and smaller trees are left to be cut later. Sometimes the best trees are left to provide seed for future generations. Sometimes trees are left for wildlife habitat and recreation. | 3 | |
| 3830797063 | Rotation Time | Time between cuts of a stand or area of forest. | 4 | |
| 3830798484 | Public Lands | Any land or land interest owned by the federal government within the 50 states, not including offshore federal lands or lands held in trust for Native American groups. | 5 | |
| 3830798485 | Restricted-Use Land | Land that is only allowed limited amounts of recreation, hunting, and other human activities. | 6 | |
| 3830801078 | National Wildlife Refuge | Is a designation for certain protected areas of the United States managed by the United States Fish and Wildlife Service. The National Wildlife Refuge system is a network of lands and waters managed to protect wildlife and wildlife habitat. The system consists of over 500 refuges across the nation. | 7 | |
| 3830805119 | National Resource Lands | Lands that are protected to be used as sources for renewable resources, such as timber. | 8 | |
| 3830805129 | US Forest Service | A United States government agency within the United States Department of Agriculture, is under the leadership of the United States Secretary of Agriculture and protects and manages forests in the U.S. | 9 | |
| 3830808964 | US Fish and Wildlife Service | Is a unit of the United States Department of the Interior that is dedicated to managing and preserving wildlife. | 10 | |
| 3830808965 | Controlled Burn | Using prescribed fire to reduce the risk from wildfires, control tree diseases, increase food and habitat for wildlife, and manage forests for greater production of desirable tree species. | 11 | |
| 3830808966 | Ecological Island | An area that is biologically isolated so that a species occurring within the area cannot mix (or only rarely mixes) with any other population of the same species. | 12 | |
| 3830811019 | Commercial Forestry | In order to retain biodiversity in commercial forest, they must be managed in ways that simulate disturbances that take place in old-growth forests, such as forest fires and storms. Over time, some of the structural characteristics of old-growth forests, such as old trees, deadwood and deciduous trees, can also be added. | 13 | |
| 3830811020 | Second- Growth Forests | Forest that has been clear-cut and re-grown. | 14 | |
| 3830813428 | Clear Cutting | In timber harvesting, the practice of cutting all trees in a stand at the same time. | 15 | |
| 3830813429 | Strip Cutting | In timber harvesting, the practice of cutting narrow rows of forest, leaving wooded corridors. | 16 | |
| 3830814616 | Thinning | is in forestry a type of selective cutting primarily undertaken to make the forest more profitable in an upcoming final felling. Most of the harvest in thinning is pulpwood as only mature trees are suitable for timber. | 17 | |
| 3830814617 | Multiple- Use Land | Literally, using the land for more than one purpose at the same time. | 18 | |
| 3830816469 | National Park | A relatively large area containing representative examples of major natural regions, features, or scenery of national or international significance. National park ecosystems are not heavily altered by humans and they are protected by national governments. | 19 | |
| 3830816470 | National Forest | are protected forest woodland areas in the United States. National forests are controlled by the federal government and managed by the United States Forest Service, under the direction of the United States Secretary of Agriculture. The management of these lands focuses on timber harvesting, livestock grazing, water, wildlife, and recreation. Commercial use of national forests is permitted and in many cases encouraged, unlike national parks. | 20 | |
| 3830819779 | Riparian Zones (areas) | Thin strips and patches of land and vegetation that border streams. | 21 | |
| 3830821195 | US National Park Service | is the United States Federal Government agency that deals with all National Parks, many National Monuments, and other conservation properties with various designations. | 22 | |
| 3830823164 | US Bureau of Land Management | is an agency within the United States Department of the Interior which administers America's public lands, totaling 262 million acres (1,060,000 km) or one-eighth of the landmass of the country. | 23 | |
| 3830823165 | Edge Effect | An effect that occurs following the forming of a forest island; in the early phases the species diversity along the edge is greater than in the interior. Species escape from the cut area and seek refuge in the border of the forest, where some may last only a short time. | 24 |
