In 2006, the U.S. Senate designated the third Friday of May as Endangered Species Day to raise awareness about imperiled species and the successes in species recovery due to protections by the U.S. Endangered Species Act (ESA). This year also marks the 40th anniversary of the passage of the ESA.
Endangered species recovery is a socio-environmental issue because species conservation involves not only the species of concern, but also the human populations that interact with the species. For example, people may depend upon the use of resources, such as timber in an endangered species’ habitat, and protection of that habitat may change or even eliminate that resource’s availability. Wildlife managers must balance these social and economic considerations with the species’ ecological requirements when creating recovery plans to conserve species.
Because each species has a unique combination of specific biological needs, threats, and social context, management actions and recovery goals can vary tremendously among species. However, that does not necessarily mean that recovery plans are inconsistent or not based on the best available science. As a postdoc at SESYNC, my research aims to understand to what extent the recovery targets for endangered species are based on species’ needs, which are relatively transparent, compared to social, political, or economic factors, which are often not explicitly stated in the recovery plans. One of the goals of this work is to encourage more transparency in the managers’ decision-making process. This research would also quantify relationships between recovery targets and various species attributes, which may be used to establish targets for species with too little biological data to set species-specific targets. There are many such species, including the majority of the 338 Hawaiian plant species that are listed under the ESA.
Celebrate this year’s Endangered Species Day by learning about the endangered and threatened plant and animal species in your area, or listening to the success stories about species that have improved their status on the U.S. Fish & Wildlife Service website. To find out more about Endangered Species Day, including events in your area and podcasts by the Endangered Species Coalition, visit www.stopextinction.org/esd.html. If you are in the Washington, D.C., area, consider attending the Endangered Species Day events at the U.S. Botanic Garden on May 17.
