Land use

Maximum sustainable yield

• Maximum amount of a renewable resource that can be harvested without compromising the future availability of the resource

• A cost or benefit of a good or service not included in the purchase price

• Areas actively managed to preserve biotic components of their ecosystem

• A fire deliberately set under controlled conditions in order to reduce the accumulation of dead biomass on a forest floor

Maximum sustainable yield

• 25% of carrying capacity

• 50% of carrying capacity

• 75% of carrying capacity

• 100% of carrying capacity

Tragedy of the commons

• People should maximize the use of resources based on the greatest good for everyone

• Lands managed to preserve natural habitats; resource extraction is not allowed

• When a shared, limited resource becomes depleted if it is not managed in some way

• A cost or benefit of a good or service not included in the purchase price

Resource conservation ethic

• People should maximize the use of resources based on the greatest good for everyone

• Areas actively managed to preserve biotic components of their ecosystem

• A large area typically planted with a single rapidly growing tree species.

• A 1973 U.S. act designed to protect species from extinction

Externality

• Original purchase price

• Taxes applied to suburban real estate transactions

• A cost or benefit of a good or service not included in the purchase price

• When a shared, limited resource becomes depleted if it is not managed in some way

National park

• Lands that can be used for recreation, grazing, timber harvesting and mineral extraction (USA)

• Lands open for use of resources, but managed for multiple uses

• Areas actively managed to preserve biotic components of their ecosystem

• Lands managed to preserve natural habitats; resource extraction is not allowed

Manages grazing, mining, timber harvesting and recreation

• BLM

• USFS

• NPS

• FWS

Selective cutting

• Cut down all of the trees

• A large area typically planted with a single rapidly growing tree species.

• Removal of single or just a few trees from a larger forest

• A fire deliberately set under controlled conditions in order to reduce the accumulation of dead biomass on a forest floor

Environmental impact statement

• A 1969 U.S. federal act that mandates an environmental assessment of all projects involving federal money or federal permits.

• A plan that outlines how a developer will address concerns raised by a project’s impact on the environment.

• A document outlining the scope and purpose of a development project, describing the environmental context, suggesting alternative approaches to the project, and analyzing the environmental impact of each alternative.

• A 1973 U.S. act designed to protect species from extinction

Suburb

• An area similar to a suburb, but unconnected to any central city or densely populated area.

• The degradation of the built and social environments of the city that often accompanies and accelerates migration to the suburbs.

• Urbanized areas that spread into rural areas, removing clear boundaries between the two

• An area surrounding a metropolitan center, with a comparatively low population density
