美国在物种保护方面的努力往往是机会主义和不协调的。然而，最近，生态学家和经济学家已经开始开发更系统的方法。这里讨论了在生物保护区选址中如何有效地分配稀缺的保护资源的问题。通过使用关于地价和濒危物种发生率的县级数据，研究表明，无论是实现固定物种覆盖面的成本，还是从固定预算获得的覆盖面，考虑到地价的异质性都会大大提高效率。
Efforts at species conservation in the United States have tended to be opportunistic and uncoordinated. Recently, however, ecologists and economists have begun to develop more systematic approaches. Here, the problem of efficiently allocating scarce conservation resources in the selection of sites for biological reserves is addressed. With the use of county-level data on land prices and the incidence of endangered species, it is shown that accounting for heterogeneity in land prices results in a substantial increase in efficiency in terms of either the cost of achieving a fixed coverage of species or the coverage attained from a fixed budget.
