Heath Bartosh is Co?Founder and Senior Botanist of Nomad Ecology, based in Martinez, California, and a Research Associate at the University and Jepson Herbaria at UC Berkeley. After graduating from Humboldt State University, Heath began his career as a professional botanist in 2002 and has been an earnest student of the California flora for nearly 20 years. His general research interests are in California vascular plant floristics with a focus on distribution, soil and geologic relationships, endemism, regional and local rarity, and habitat conservation. At a more specific level, his primary interests are floristics of the California Coast Ranges and the fire-following annual plant species found there. His research on post-fire floras focuses on the composition and duration of the eruptive dominance and subsequent fleeting abundance of annual plant species at regional scales within the California Coast Ranges. In 2009, he also became a member of the Rare Plant Program Committee at the state level of CNPS, helping to develop current and accurate information on the distribution, ecology, and conservation status of California's rare and endangered plants and promoting the use of this information to influence plant conservation in California.

His immediate attention is on the communities of crustose lichens that grow on evergreen leaves of trees and shrubs in the hypermaritime temperate forests of California’s northwest coast. He is the President of the California Lichen Society, where he advocates that even neophytes can contribute to the understanding of California’s lichen flora, much of which still remains to be discovered. He is the President of the California Lichen Society (CALS) and the past Editor of its Bulletin, and a member of the British Lichen Society, the American Bryological and Lichenological Society, and the CALS Conservation Committee.

Terry Huffman was the U.S. Army Corps of Engineer's (Corps) Chief Wetlands Scientist responsible for the development of technology directed toward assisting the Corps's Regulatory Program. While at the Corps’ Environmental Laboratory in Vicksburg, Mississippi, Dr. Huffman developed the wetlands definition currently in use by the Corps and the U.S. Environmental Protection Agency (EPA) Clean Water Act (CWA) Section 404 Regulatory Program and conducted research and development activities which pioneered the use of multiple field indicators to determine the presence of wetland vegetation, soil, and hydrology conditions. This seminal work led to the development of the wetland delineation methodology in use by the Corps and EPA today. As noted in the preface to the Corps’ 1987 Wetlands Delineation Manual, Part II of the Manual is based on Dr. Huffman’s 1980 paper entitled Multiple Parameter Approach to the Field Identification and Delineation of Wetlands. He has also served as a technical member for the Regional Water Quality Control Board’s (RWQCB) Technical Advisory Team, which developed state wetlands, stream, and riparian definitions; identification criteria, indicator methodology; and technical memorandum for RWQCB regulatory use. Founder of the private consulting firm Huffman-Broadway Group, he has conducted wetland and other waters (aquatic resources) jurisdictional boundary determinations using various agency required methodologies, reviewed and developed regulatory programs and procedures, and developed evidence for litigation and provided expert testimony.

Julie Kierstead has spent her career promoting the discovery, enjoyment, and conservation of the flora of the western United States. From 1989 through 2019, she was Forest Botanist for the Shasta-Trinity National Forest in Northern California. Before that, she started the Berry Botanic Garden Seed Bank for Rare and Endangered Plants of the Pacific Northwest.

In 2019, Julie discovered a distinctive new species of Phacelia from the mountains of western Shasta County, soon to be published under the name Phacelia damnatio. Julie has contributed over 2,300 free-use photos to CalPhotos and many hundreds of voucher specimens from the Klamath and Cascade Ranges to California herbaria. She is a member of the Rare Plant Program Committee at the state level of CNPS and sits on the Board of Directors of Northern California Botanists.
