Current Activities

Sean Hayes became Chief of the Protected Species Branch in 2016. As Branch Chief, Sean works with branch and center staff to support sound science geared at quantifying the relative impacts of various limiting factors preventing the recovery of endangered species, as well continued ecological research, population assessment and study of anthropogenic impacts such ocean noise and bycatch on protected marine species. Sean believes the principal goal of the Protected Species Branch science is to further our understanding of our animals and their ecological needs/challenges in order to remove the ambiguity around areas of stake holder concern. Whether clarifying the relative impact of shipping, fishing or climate change on endangered species, or understanding the impacts of recovering pinnipeds on a food web that includes human consumers, the purpose of the Protected Species Branch is to enable managers and stakeholders to make scientifically informed decisions towards sustainable human uses of marine resources in the North Atlantic.

A theme that has been running through Sean's research efforts both as a scientist and now program manager is developing creative 'out of the box' techniques to address previously 'unanswerable' questions for the purposes of understanding the constantly shifting balance in ecosystems resulting from anthropogenic impacts of things like habitat alteration, introduced species and increased resource consumption. As society grapples with balancing the social expectations for things to be 'the way they were', while being regularly confronted with the unintended consequences of human population growth and technological advancement, Sean is fascinated by the challenge of using science to help society advance while moving down a path of sustainability.

Background

Sean considers the duties of civil service to be the most rewarding career possible and is thankful for the opportunity to work on the very challenging science and conservation issues surrounding protected species in both in Northeast US waters as well as national and international waters. He recognizes this can only be done through strong partnerships with federal, state, academic, industry, and non-governmental organization partners. The work is never dull and the results of our work are always important.

After growing up on a sheep farm in upstate NY, Sean received undergraduate degrees from SUNY Cobleskill and Cornell and his PhD from UC Santa Cruz where he studied marine mammal communication, physiology and reproductive behavior in large cetaceans and pinnipeds. Sean began working for the Pacific Islands Fisheries Science Center (then Southwest Fisheries Science Center) on Hawaiian monk seals in 2001, and then transitioned to salmon and the Southwest Fisheries Science Center Santa Cruz lab from 2002-2016, where he developed and led several research programs working on the life history and ecology Pacific salmon species across a range of environments from small coastal streams to large inland rivers, through estuaries and in the marine environment. Sean participated in NOAA's Leadership Competencies Development Program between 2014-2016, where he gained both a greater understanding of civic duty and an appreciation for the massive size of NOAA's seemingly impossible mission. In an agency of many talented scientists, Sean decided to explore whether he could make a greater contribution to the agency by blending his years of science experience with newly trained leadership skills by working in more of a management capacity. In May 2016, Sean became the Protected Species Branch Chief at NOAA's Northeast Fisheries Science Center in Woods Hole Massachusetts where he is supervising the teams managing the center's Endangered Species Act and Marine Mammal Protection Act based research portfolio including salmon, marine mammal and sea-turtle research programs and is currently enjoying a 'sweet spot' where he remains engaged with the science but working to focus scientific effort on where our greatest needs are and will be. He also is enjoying being much closer to his family and farm in NY, and exploring life in his new home on beautiful Cape Cod with his pups and partner.
