Conservation easement: A right which one person has relative to the land of another for the specific purpose of protection of property against loss, misuses, or waste, particularly in the modern sense of the term, natural resources, wildlife, and natural settings in mountains, rivers, lakes, prairies, etc. not inconsistent with general property rights of the owner.
Covenant. An agreement between two or more persons, often written into a deed, to do or refrain from doing certain acts.

Development rights. The rights to develop land, as distinguished from ownership of it. Similar but broader than conservation easement, because development rights may be purchased with the aim of developing instead of conserving private land.
Easement. An acquired right of use, interest, or privilege in lands owned by another. Easements are more permanent and often more restrictive than municipal land use regulation, which can shift with the political winds.
Eminent domain. The right of a government to acquire private property for public use or benefit upon payment of just compensation. The term “condemnation” is often used interchangeably with eminent domain but may also apply to the demolition by public authority of a dangerous structure where no compensation is paid and the condemned property is not acquired by the government.

The concept is of British origin, but in the United States loosely describes almost any kind of green space.
Greenways. A linear open space established along a corridor, such as a river or railroad right-of way, and usually developed for non-vehicular public use. Examples include the Platte River Greenway in Denver, the Capital Area Greenway in Raleigh, North Carolina, and the Willamette Greenway in Portland, Oregon.
Land development. The improvement of land with utilities and services, making the land more suitable for resale as developable plots for housing or other purposes.
Land trust. Predominantly nonprofit local, regional, or statewide organizations that work with private landowners to protect their land for conservation, recreation, and other public benefit. Typically, land trusts acquire land, conservation easements, management agreements, or other interests in real property for the establishment of such public purposes as urban parks, gardens, greenways, wildlife corridors, open space, wetlands, groundwater-recharge areas, wildlife habitat, and river corridors or for the preservation of historic lands or existing land-uses, such as agriculture. Each land trust has its own mission statement, specific to its setting and region. In 1998, the United States had more than 1,200 land trusts, distributed over all but three states (Oklahoma, Arkansas, and South Dakota). The trusts owned more than 800,000 acres and owned conservation easements on almost 1.4 million acres. They had transferred almost a million acres to third parties and had protected 1.8 million acres of land by other methods.
Land-use plan. The official formulation of the desired future uses of land, including the public and private improvements to be made on it and the assumptions and reasons for arriving at the determinations.
