Climate change and invasive species are jeopardizing already endangered and threatened species, prompting the U.S. Fish and Wildlife Service (FWS) to finalize its 2023 rule allowing experimental populations to be introduced into habitat outside their historical range, as long as the areas are capable of supporting the experimental population.

Since passage of the early natural resource protection laws and regulations in the United States decades ago, legal, technical, and economic practitioners have been challenged with understanding the ever-changing and ever-evolving environmental law and policy landscape. Riveting changes have advanced the position of natural resources and related matters of conservation and biodiversity across domestic and international agendas, in corporate, government, and public interest agendas, and in the lives of everyday citizens.

December 2023 marked 50 years since the Endangered Species Act (ESA) was signed into law. The ESA has proven resilient to numerous legal challenges and saved many species from extinction. But its overall success has been debated, as the list of endangered and threatened species continues to grow, and only 54 species have been taken off of the list completely. On October 26, 2023, the Environmental Law Institute hosted a panel of experts who explored the successes and shortcomings of the statute and discussed what might happen next as climate change increases the risk of extinction.

Congress in the 2020s has authorized three new environmentally focused grant programs relating to western waters and appropriated $450 million in multi-year funding. The Bureau of Reclamation is responsible for creating and implementing these programs, giving it a new tool and resources for addressing stubborn environmental problems—some caused by the Bureau’s many dams.

U.S.-Canadian management of marine migratory species is a particularly rich place to understand the complex relationship between migratory science, conservation, and law. The two nations share a large border, have a long-lasting historic friendship, and already collaborate extensively. However, the relationship is not without contention. The substantial economic interests in the oceans and differences in governance structure have not infrequently frustrated efforts at cooperative management.

On August 29, 2023, the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers issued a direct final rule that revised the “waters of the United States” (WOTUS) definition rule. This rule amended the final WOTUS rule, previously published in January 2023, to be consistent with the Supreme Court’s May decision in Sackett v. Environmental Protection Agency. On September 14, the Environmental Law Institute hosted a panel of experts to analyze the new rule and discuss its regulatory and policy consequences.

Communities around the world are seeking to acknowledge nature’s rights through legal tools and litigation. This Article provides an overview of recent developments in earth law movements, including Rights of Nature, Rights of Rivers, and Ocean Rights, and considers the potential impacts these ecocentric conservation measures could have on Indigenous peoples and local communities.
