2014 Humane Society v. Jewell (D.D.C.)
Summary: Canis lupus first received ESA protection as an entire species in 1978, when FWS listed all gray wolves in two populations: one in Minnesota listed as threatened, and one listed as endangered in all other 47 coterminous states. Because the ESA did not at that time contain the term “distinct population segment” (DPS) within the definition of “species,” FWS considered the two populations to be separate “species” for listing purposes and applied the five listing criteria to each population separately.
In 2011, FWS issued a rule in its fourth attempt to delist wolves in Minnesota, Wisconsin and Michigan. The mechanism FWS used to accomplish the delisting was to “revise” the existing listing for Minnesota gray wolves to establish it as the Western Great Lakes (WGL) DPS, to expand the boundaries of that DPS beyond Minnesota to eight other Midwestern states, and then to remove that DPS from ESA protection. FWS concluded that the WGL wolves were not in danger of extinction nor likely to become so in the foreseeable future, throughout all or a significant part of their range, with that range defined by the borders of the DPS. This rule became effective on January 27, 2012 and was challenged by the HSUS plaintiffs.
The District Court first determined that the plaintiffs had standing to bring the case. Then the court found several separate reasons for invalidating the 2011 delisting rule.
First, the court found that the structure, history and purpose of the ESA do not allow FWS to identify a DPS solely to delist a vertebrate population. The court determined that designating a DPS for the purpose of not listing a vertebrate population makes no sense within the context of the ESA because, to identify a DPS, FWS must first determined that the vertebrates, as a distinct group, are threatened with extinction. Absent that determination, the ESA does not authorize FWS to recognize and create a DPS at all. “In short, the creation or initial designation of a DPS operates as a one-way ratchet to provide ESA protections” to the covered wildlife. The court determined that FWS’ interpretation of the statute was not entitled to any Chevron deference because it directly conflicted with the structure of the statute. The court also held that the Minnesota wolf population was not an extant DPS at the time of the 2011 final rule because FWS had never designated or treated it as such, and it did not and could not meet the requirements set forth in FWS’ DPS Policy. Furthermore, expanding the size and contours of a DPS boundary from a single state to all or part of nine states runs counter to the DPS Policy, which reflects the notion that a DPS is a generally static designation.
Second, the court found that the ESA does not allow the designation of a DPS made up of vertebrates already protected under the ESA at a more general taxonomic level. Because wolves were already listed at the species level as Canis lupus, the structure and purpose of the ESA prohibit FWS from reducing that protection by manipulating the definition of “species” to treat the DPS animals as if they were a different, unlisted species. Instead of considering the status of the entire listed species as a whole, the 2011 rule impermissibly focused solely on the viability of a single population of wolves in only a part of their historic range. Once FWS lists a species, that species becomes the entity protected under the ESA and the agency’s subsequent actions, whether review or delisting, must address that entire listed entity.
As a third, stand-alone reason for invalidating the rule, the court found that the delisting rule was contrary to the evidence before FWS. FWS failed to explain why territory suitable for wolf occupation is not a significant part of the gray wolf’s range. The court followed Ninth Circuit precedent requiring FWS to explain why territory that is part of a species’ historical range but no longer occupied by that species, falls outside a significant portion of the species’ range for ESA purposes. FWS failed to provide such explanation in the 2011 rule, instead focusing on the species’ status within its current range. FWS also failed to explain the impact of combined mortality factors. The record showed that the WGL wolf population is vulnerable to disease and human-caused mortality, yet FWS failed to address how the two factors could interact to create a clear threat to the species.
In light of its findings, the court determined that the proper remedy was complete vacatur of the 2011 rule. The court ordered vacatur and reinstated the original 1978 rule which provides that gray wolves in Minnesota are listed as threatened and gray wolves in all other coterminous states are endangered.
