Dr. Merz is a registered scientist with the American Fisheries Society. He has over 20 years of experience working with aquatic resources and has been the principal scientist on several salmonid habitat restoration programs in the California Central Valley. He has taught environmental science, salmon biology and restoration courses for the past fourteen years.
Joe is known for his work with human and fisheries habitat interactions, and for his ability to communicate with scientific and stakeholder audiences alike. He has earned degrees in Environmental and Systematic Biology (Bachelors), Cal Poly at San Luis Obispo (1991); Biological Conservation (Masters), California State University, Sacramento (1994); and Conservation Ecology (Ph.D.), University of California, Davis (2004).
Dr. Merz has worked for California public, provide and non-profit entities on resource monitoring and fisheries habitat enhancement. He is noted as an environmental studies and natural resources lecturer, and for his successes working with stakeholders. He has coauthored a variety of peer-reviewed publications*, focusing on river rehabilitation, fish movement, invasive species, woody debris/redd associations, and evaluation of spawning habitat enhancement, among others. In line with his professional interests, he is a member of the Ecological Society of America, the American Fisheries Society and the Southwestern Association of Naturalists. Dr. Merz has been honored with a variety of awards and has received research and restoration grants from multiple stakeholders for restoration related projects in California, Oregon and Washington for salmonid habitat restoration; salmonid management and reintroduction; monitoring of fish migration and movement; fish passage improvement; and assessment of invasive species interactions with native salmonid populations.
Dr. Rocko Brown is an expert design geomorphologist who uniquely balances applied and scientific aspects of geomorphology and engineering. He focuses on process-based assessment and restoration of fisheries resources through channel manipulation integrating geomorphic, hydraulic and ecological frameworks. He has extensive experience in hydraulic and sediment transport modeling and design for fish passage improvements, channel design, large wood and instream habitat structures, and bank stabilization.
Rocko has led the design of seasonal floodplain, spawning habitat, and fish passage projects in a diverse array of physical and regulatory settings. He has made contributions to spawning habitat rehabilitation efforts, including assessment, modeling, design and construction of projects on several of California’s most-important rivers. Dr. Brown has published heavily on evaluating the interactions of topography and flow hydrology for geomorphic processes needed for salmonids to complete their life cycle and how to design functional riverscapes that honor these linkages. He holds a Bachelor of Science in Environmental Engineering from Temple University and Master’s and Doctorate Degrees in Hydrologic Sciences from the University of California, Davis. He has been an instructor with NWETC since 2009.
