State wildlife agencies commonly claim they are entitled to manage wildlife under the public trust doctrine (PTD). This assertion is frequently made in judicial proceedings, with state requests that their managerial authority be given due force throughout state, private, federal, and even tribal lands. One might conclude that a rich body of PTD practices and policies exists for wildlife; in reality, the PTD in state wildlife management proves to be ephemeral.

On May 7, President Donald Trump issued Executive Order No. 13921, Promoting American Seafood Competitiveness and Economic Growth, stating that it is U.S. policy to “facilitate aquaculture projects through regulatory transparency and long-term strategic planning.” To further this policy, the Order directs the U.S. Army Corps of Engineers to create a nationwide permit for aquaculture operations, and tasks the National Oceanic and Atmospheric Administration with a variety of planning- and permit-related responsibilities.

The U.S. Supreme Court’s opinion in Weyerhaeuser Co. v. U.S. Fish & Wildlife Service raises important questions about the scope of the Endangered Species Act’s (ESA’s) protections for critical habitat. Foremost among them is a question one might think was long settled: what is “habitat”? In a short ruling, the Weyerhaeuser Court opined that “critical habitat” must first be “habitat,” but it did not attempt to define exactly what habitat is or how much deference the U.S. Fish and Wildlife Service should get on what is both a biological and policy question.

This Article, adapted from Chapter 16 of What Can Animal Law Learn From Environmental Law?, 2d Edition (ELI Press, forthcoming 2020), explores existing and potential wildlife conservation policies that could play a vital role in mitigating global climate change. It describes how climate change is impacting wildlife and biodiversity around the globe and reviews the history and current state of U.S. policy, including how the federal government currently manages climate change issues under the ESA.

Section 401 certification and permit conditioning under the Clean Water Act is one of the most significant tools for states to influence federally permitted activities involving discharges into navigable waters. However, states are required to set conditions within one year or they forgo their ability to do so. In practice, the one-year review is difficult for states to meet and led to a common practice known as “withdraw and resubmit” in which states could reset the clock. But in Hoopa Valley Tribe v. Federal Energy Regulatory Comm’n, the D.C.

Throughout the world, people struggle to gain access to stable sources of clean water. While there are increasingly innovative solutions being developed, many communities simply do not have access to efficient, centralized wastewater management systems, and as a result, face difficulty finding reliable sources of water for daily use. There is a great need to implement novel systems that can fill the gap, especially for isolated or “off-grid” communities.
