He has a broad understanding of aquatic resource issues associated with hydroelectric projects (licensing and compliance), urban and rural development and forest management activities. He applies this knowledge to aquatic study plan development, NEPA processes and ESA consultation.
	Jason Shappart Fisheries Scientist Jason has over 21 years of experience determining fish distribution, abundance, habitat requirements, and limiting factors in the Pacific Northwest, focusing on freshwater systems. His particular areas of interest are arid landscapes and bull trout ecology. Over the last 16 years, his work has focused on fish and habitat issues related to hydropower operations and habitat restoration. He has a thorough understanding of ESA, wetland, and in-water work regulations and has managed compliance and permitting for many large water resource projects, including habitat restoration, fish passage, irrigation diversions and monitoring facilities. Jason is based in Oregon.
	Mike Bonoff Senior Aquatic Scientist Mike joined the Meridian Team in December, 2017, having worked closely with the firm’s founders in the 1990s. He is an aquatic scientist specializing in surface water impact assessment, reservoir limnology, and stream ecology. Mike has over 30 years of experience as a consultant, with a focus on Endangered Species Act, Clean Water Act, and NEPA compliance for transportation projects and hydroelectric project relicensing. Mike has led State, Federal and local permitting for numerous projects involving in-water work throughout Oregon and Washington, including fish passage, bank stabilization, habitat enhancement, and dam removal. He has published peer-reviewed technical papers on reservoir limnology, stream ecology, and field methods for sample collection in lakes, streams, and rivers.
	Jeff Boyce Forest Ecologist / NEPA Specialist / GIS Analyst As a Certified Forester, Jeff has expertise in silvicultural management to benefit both forest health and wildlife habitat. His range of skills includes land use planning, GIS analysis, logistic planning for remote field studies, visual resource assessments, photo interpretation, and database design. He is adept at identifying efficient methods to collect and evaluate field data that focuses on the resource issue of interest and allows for better decision-making. With over 25 years of experience in resource evaluations and field investigations throughout the Pacific Northwest and Alaska, Jeff is a valued member of environmental assessment and engineering feasibility teams. He has performed NEPA evaluations of large land use and water resource development projects on federal and tribal lands. Jeff helps clients navigate the complexities of Forest Service planning regulations, special use permitting, and other regulatory requirements.
	Robyn Rice Fisheries Biologist Robyn specializes in assessing marine and freshwater aquatic populations and implementing water quality investigations. She has performed fish abundance studies, habitat usage studies, water quality monitoring and food web analyses including stomach content identification. She is trained in the Army Corps' Eelgrass Delineation protocol and the use of hydroacoustic technology to monitor fish abundance. Robyn is an FAA certified UAV Remote Pilot and oversees Meridian's aerial operations. When not in the field, she prepares biological assessments for aquatic resources, develops water quality monitoring plans, analyzes natural resource management regulations, and conducts research on fish population trends. Robyn also is a document control and production expert.
	Joan Nichol Senior Environmental Planner and Technical Editor Joan has worked on complex water resource projects for over 30 years, coordinating teams of scientists with engineers and preparing technical reports of many types. Much of her work involves permitting projects in rural landscapes, from new dams to riverine habitat restoration to fish passage facilities. She is an experienced technical editor who works with large groups seeking to produce natural resource plans and reports.
	Brittany Winston Fisheries Biologist Brittany has a bachelor's in biology and a minor in environmental sciences from Washington State University. Upon graduation she participated in a long-term study collecting data on small mammals, fish, amphibians, and arthropods within the Mt. St. Helens National Volcanic Monument. Since 2012, she has been studying adult and juvenile salmonids as part of the Lewis River Hydroelectric Projects license implementation. This work includes on-going salmon and bull trout spawning surveys, screw trap operations, PIT tagging, and fish passage facility operations.
	Tyler McClure Fish and Wildlife Biologist With a degree in Ecology and Conservation Biology, Tyler worked as a Wildlife Technician for the Idaho Dept. of Fish and Game (IDFG) for 4 years. With a wide range of experience surveying terrestrial and aquatic vertebrates, Tyler has participated in determining local abundances of waterfowl, mourning doves, ring-necked doves, and white pelicans. Working for IDFG he managed and maintained approximately 3,000 acres of state owned land while performing vegetation monitoring, and habitat restoration with a focus on promoting galliforme population recovery. For the past 3.5 years, he has been studying adult and juvenile salmonids as part of the Lewis River Hydroelectric Projects license implementation. This work includes on-going salmon and bull trout spawning surveys, screw trap operations, PIT tagging, and fish passage facility operations.
