It continues with a discussion of the basic scientific theory underlying the Act and provides an overview of its key regulations. The author also examines the Act in the context of other key environmental planning statutes such as the National Environmental Policy Act and the Clean Water Act, especially Section 404 of the Clean Water Act, which relates specifically to wetlands.

The remainder of the book details the regulatory processes faced by other government agencies and private developers who must routinely ensure that their actions comply with the Endangered Species Act. It concludes with a broad discussion of current controversies associated with the Act and how those controversies might ultimately change how environmental practitioners will have to comply with the Act in the future.

The presentation is factual and avoids the hype and hyperbole commonly directed at the Act by both environmental activists and deregulation proponents. Readers will gain a solid understanding of how the Act was established, what goals were envisioned by its framers, how current environmental practice under the Act has been shaped, and how those practices might be changed in the future.
