A view of resource extraction as a mutually advantageous long-term partnership with nature (N. Langston 1995). Forestry may be managed as a slow-growing but renewable resource of fuel and timber and a sustained-yield recreational resource. McCarthy (2006) AAAG 96, 1 chronicles the failures of forestry sustained-yield policies to achieve their stated goals. The implications of sustainable yield resource input depend on the relative importance of capital and resource inputs in production (M. Common and S. Stagl 2005).
