Daniel R. Brumbaugh, Ph.D.
Dr. Daniel R. Brumbaugh, a marine ecologist with over 20 years of experience, specializing in coral reef ecology, focusing on reef monitoring techniques, studies of coral recruitment, and the science and management of marine protected areas. For 12 years, Dan studied coral reef and other marine ecosystems in The Bahamas and applied this knowledge to Bahamian marine conservation and education. During this time, he led a number of interdisciplinary investigations, including the Bahamas Biocomplexity Project, to study how an expanding system of marine protected areas in the country could function. He also participates on the governing Council and Scientific Advisory Committee of the Bahamas National Trust, and has advised the Bahamas Department of Marine Resources (then Fisheries) on applications of marine science to reserve planning. In the U.S., Dan has served on the stakeholder Advisory Council of the Channel Islands National Marine Sanctuary and as a Visiting Scientist with the U.S. National Marine Protected Areas Center. He also is also an individual member of the World Commission on Protected Areas (WCPA, part of the World Conservation Union, or IUCN) and is on the Advisory Board of the non-profit OneReef, which facilitates reef conservation agreements between funders and reef-owning communities in Micronesia.

Shane Cherry, M.S.
Shane Cherry has served as a principal investigator on geomorphology and hydraulic studies for watersheds, large rivers, and streams in diverse settings around the United States. He has worked as a professional geomorphologist and consultant since 1996 leading projects involving river process modeling and analysis, environmental permitting, mitigation strategy, and ecosystem restoration. Shane works on airport and transportation infrastructure projects, mining projects, and sediment remediation sites. Shane’s river and stream restoration experience includes over 80 projects. Shane engenders tremendous confidence in clients, and is a strong consensus builder through his calm articulation of ideas and concepts. Shane employs level-headed wisdom to solve problems directly and efficiently with a talent for building consensus among internal and external stakeholders. This style makes him especially effective in contentious situations around large capital project permitting and multi-party environmental remediation. He offers comprehensive skills in applied science, environmental permitting strategy, and project management that he applies to watershed studies, ecological restoration, habitat design, flood studies, and river process modeling.

Joseph Ehrenberger, M.S.
Joseph Ehrenberger’s career of 11 years as an ecologist includes a broad diversity of skills and experiences, with an emphasis on wildlife and habitat assessments. His portfolio includes assisting with husbandry and breeding of rare species in the U.S., Dominican Republic, and Grand Cayman. His field experiences concentrated on general wildlife and habitat assessments, as well as special-status species surveys (e.g. Greater sage grouse, Lesser prairie chicken, Mexican spotted owl, Indiana bat, Swift fox, raptor nest monitoring, Ricord’s iguana, and plants such as the Ute’s ladies tresses and Colorado butterfly plant). His habitat work includes restoration for Preble’s meadow jumping mouse and Kremmling milkvetch, as well as rangeland noxious weed management, mountain pine beetle control, and energy development mitigation. Most recently, he conducted focused surveys throughout Colorado for amphibians and reptiles, including rattlesnake management projects and safety training for governments and the private sector. He has authored numerous technical publications and agency documents. Furthermore, his coordination of volunteers has proven essential to non-profit and federal species and habitat monitoring programs. Joseph received his Bachelor’s degree in Teaching from Virginia Tech and his Master’s degree in Ecology from Indiana State University.
