      abstract = {Approaches to valuing regional responses in plant  productivity from investment in natural resource management  are reviewed. The usefulness of data from surveys for  estimating marginal physical product is discussed. Since  investment reduces declining trends in productivity, an  estimate of value marginal product based on based on milk  price has seemed appropriate. But as forage is an  increasingly substitutable intermediate product in dairy  production systems its value will not exceed that of the  least cost substitute. Qualified estimates indicate the  extent of overestimation of benefits produced by some  previous approaches. Implications for natural resource  management policy are considered.},
