J.B. Ruhl (Florida State University College of Law) has posted Toward a Common Law of Ecosystem Services (St. Thomas Law Review, Vol. 18, No. 2, 2005) on SSRN. Here is the abstract:
This article suggests ways in which the common law can integrate concepts of ecosystem services to fulfill pragmatic objectives of common law doctrine. Rather than requiring a radical departure from traditional common law doctrine as is often proposed in environmental literature on the common law, ecosystem services can fold seamlessly into existing common law principles as a source of new knowledge and changed circumstances.
