This REU Site award to the Smithsonian-Mason School of Conservation, located at the Smithsonian’s National Zoo and Conservation Biology Institute in Front Royal, VA, will support the training of 10 students for 10 weeks during the summers of 2026- 2028. Undergraduate students will have the opportunity to conduct hands-on conservation research and gain career-ready skills to develop the best management practices for the conservation of threatened species, with the goal of helping to alleviate species extinction globally. The REU connects students with the greater conservation community as they meet and network with researchers in the field, develop career skills, and share results on how their research can inform and impact species conservation. Student projects will aid in their development of field and lab research methods, data collection, management, and analysis, all of which are necessary skills for future careers in science. Students will enhance their communication skills by presenting the results of their work at a final symposium and other scientific conferences. Students should apply to the REU site using NSF ETAP (Education and Training Application) at https://etap.nsf.gov. Students will work with a mentor to develop an original inquiry-based research project within one of three conservation focal areas: 1) assessing and monitoring species in the wild, 2) understanding ecological integrity and species resilience to environmental threats, and 3) improving ca
