Planned management of a natural resource or of a particular ecosystem to prevent exploitation, pollution, destruction, or neglect and to ensure the future usability of the resource. Living resources are renewable, minerals and fossil fuels are nonrenewable. In the West, conservation efforts date to 17th-century efforts to protect European forests in the face of increasing demands for fuel and building materials. National parks, first established in the 19th century, were dedicated to the preservation of uncultivated land not only to provide a safe haven to wildlife but to protect watershed areas and help ensure a clean water supply. National legislation and international treaties and regulations aim to strike a balance between the need for development and the need to conserve the environment for the future. art conservation and restoration Civilian Conservation Corps conservation law law of conservation energy conservation of wildlife conservation; The planned management of a natural resource, with the goal of protecting and carefully preserving it from exploitation, destruction or neglect (conservation); The protection, improvement, and use of natural resources according to principles that will assure their highest economic and social service; the management of a natural resource so that it can be sustained over the long-term; From section 3(3) of the Federal Endangered Species Act: "The terms "conserve," "conserving," and "conservation" mean to use and the use of all methods and procedures which are necessary to bring any endangered species or threatened species to the point at which the measures provided under this Act are no longer necessary Such methods and procedures include, but are not limited to, all activities associated with scientific resources management such as research, census, law enforcement, habitat acquisition and maintenance, propagation, live trapping, and transportation, and, in the extraordinary case where population pressures within a given ecosystem cannot be otherwise relieved, may include regulated taking "; Use, management and protection of resources so that they are not degraded, depleted or wasted and are available on a sustainable basis for present and future generations; An approach to archaeology based on a philosophy stressing the protection, preservation, and/or managed use of the cultural resources base for future generations Protection of representative sites and preservation of data through scientific study are major aspects of this approach It differs from salvage archaeology which stressed the immediate recovery of material from threatened sites (McGimsey and Davis 1977: 109-110); Conservation is saving and protecting the environment. a four-nation regional meeting on elephant conservation. tree-planting and other conservation projects; the protection and careful use of resources and the environment Top; (physics) the maintenance of a certain quantities unchanged during chemical reactions or physical transformations; Conservation is saving and protecting historical objects or works of art such as paintings, sculptures, or buildings.

conservation law: Any of several laws that hold that some physical property remains constant in a closed system regardless of other changes that take place
conservation of mass: A conservation law of classical physics that states that the total mass of a closed system remains constant regardless of the chemical or physical changes that take place within it
conservation-law: Attributive form of conservation law, noun
conservation-of-mass: Attributive form of conservation of mass
It can be seen by inspection of the equations (6.6) that a conservation-of-mass law is satisfied: noting that in the usual experiment x_2\left(0\right)=0=x_3\left(0\right), it is x_1\left(t\right)+x_2\left(t\right)+x_3\left(t\right)=x_1\left(0\right).
Conservation biology: Conservation biology, or conservation ecology, is the science of analyzing and protecting Earth's biological diversity. Conservation biology draws from the biological, physical and social sciences, economics, and the practice of natural-resource management. Conservation ecology addresses population dynamics issues associated with the small population sizes of rare species (e.g., minimum viable populations). The term "conservation biology" refers to the application of science to the conservation of genes, populations, species, and ecosystems. Conservation biology is the scientific study of the phenomena that affect the maintenance, loss, and restoration of biological diversity.

conservation area: In Britain, a conservation area is an area where birds and animals are protected. wildlife conservation areas
conservation area: In Britain, a conservation area is an area where old buildings are protected and new building is controlled
conservation law: or law of conservation In physics, the principle that certain quantities within an isolated system do not change over time. When a substance in an isolated system changes phase, the total amount of mass does not change. When energy is changed from one form to another in an isolated system, there is no change in the total amount of energy. When a transfer of momentum occurs in an isolated system, the total amount of momentum is conserved. The same is true for electric charge in a system: charge lost by one particle is gained by another. Conservation laws make it possible to predict the macroscopic behaviour of a system without having to consider the microscopic details of a physical process or chemical reaction
conservation laws: principles of physics which dictate that electrical energy does not change but is preserved
conservation of charge: the principle that the total electric charge of a system remains constant despite changes inside the system
conservation of charge: A principle stating that the total electric charge of an isolated system remains constant regardless of changes within the system
conservation of energy: the fundamental principle of physics that the total energy of an isolated system is constant despite internal changes
conservation of energy: principle of physics which dictates that electrical energy does not change but is preserved
conservation of energy: A principle stating that the total energy of an isolated system remains constant regardless of changes within the system. Principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant, though it may take different forms (e.g., kinetic energy, potential energy, thermal energy, energy in an electric current, or energy stored in an electric field, in a magnetic field, or in chemical bonds [see bonding]). With the advent of relativity physics in 1905, mass was recognized as equivalent to energy. When accounting for a system of high-speed particles whose mass increases as a consequence of their speed, the laws of conservation of energy and conservation of mass become one conservation law. See also Hermann von Helmholtz

Nature Conservation Review: A Nature Conservation Review is a 2-volume work by Derek Ratcliffe, published by Cambridge University Press in 1977. It set out to identify the most important places for nature conservation in Great Britain. It is often known by the acronym NCR, and sites listed in it are termed "NCR sites"
Civilian Conservation Corps: (1933-42) U.S. unemployment program. One of the earliest New Deal programs, it was established to relieve unemployment during the Great Depression by providing national conservation work primarily for young unmarried men. Recruits lived in semimilitary work camps and received $30 a month as well as food and medical care. Projects included planting trees, building flood barriers, fighting forest fires, and maintaining forest roads and trails. It employed a total of 3 million men during its existence
art conservation and restoration: Maintenance and preservation of works of art, their protection from future damage, deterioration, or neglect, and the repair or renovation of works that have deteriorated or been damaged. Research in art history has relied heavily on 20th-and 21st-century technical and scientific advances in art restoration. Modern conservation practice adheres to the principle of reversibility, which dictates that treatments should not cause permanent alteration to the object

water conservation: In many areas of the East, summer brings with it water restrictions Before this can threaten the health of your plantings of trees, shrubs and perennial flowers, put a mulch down around all planted areas The best time to do this is right after a good soaking rain Use several inches of shredded bark, bark chips, peat moss, composted leaves, etc Keep the mulch an inch or sow away from the stems of your plants You'll conserve soil moisture and keep roots cool, too
