Heath Bartosh is founder, senior botanist, and rare plant specialist at Nomad Ecology, established in 2004 and based in Martinez, California. Heath has spent his career in the pursuit of a deep understanding of California rare plants and their habitats, which began in 1998 on Channel Islands National Park monitoring rare annual plants following an El Niño year as part of his undergraduate studies at Humboldt State University. Since then his professional, vocational, and volunteer efforts have focused on the Bay Area where he has taken on a variety of leadership roles. Mr. Bartosh is considered an expert in the flora and rare plants of the Bay Area, especially in the East Bay (Contra Costa and Alameda counties). Though he has conducted extensive rare plant fieldwork throughout California, focusing on distribution, soil and geologic relationships, endemism, regional and local rarity, habitat conservation, and post-fire floristics. As Nomad's senior botanist, Mr. Bartosh ensures survey methodologies utilized during botanical resource assessments, rare plant surveys, floristic studies, and both small and large-scale botanical studies conform to current guidelines and protocols endorsed and/or developed by trusted agencies. With this background, he has managed both stewardship based and CEQA/NEPA driven projects with efficiency and proficiency. Over his time in this profession he has designed and conducted rare plant inventories on nearly 150,000 acres of land throughout the San Francisco Bay Area for various public and private clients. Between 2006 and 2016 he was the Rare Plant Committee Chair for the East Bay Chapter (Alameda and Contra Costa counties) of the California Native Plant Society (CNPS). In 2009, he was appointed to the 10-person Rare Plant Program Committee at the state level of CNPS, where he now serves as Chair. His role on these committees is to ensure these programs continue to develop current, accurate information on the distribution, ecology, and conservation status of California's rare and endangered plants; and helps to promote the use of this information to influence on site plant conservation in California. Since 2013 Mr. Bartosh been a co-instructor of the annual CNPS / CDFW Rare Plant Survey Protocol Workshop training botanists, planners, and stewards on the currently accepted rare plant survey methods for fieldwork and reporting. Starting in 2015 he helped create the CNPS Botanist Certification Program for which he currently serves as the Vice Chair of the Board of Certification. In 2016 Mr. Bartosh became one of the first professional botanists to become a Certified Consulting Botanist in California through the Botanist Certification Program (Certification # CCB-002). He is also a research associate at the University and Jepson Herbaria at UC Berkeley where he pursues his research interests in East Bay and Coast Range floristics, post-fire floras, as well as serving as an instructor for Jepson Herbarium Weekend Workshops.

Roxanne Bittman is the former CNDDB Botanist, having held that position from 1986-2014. Before that, she worked for The Nature Conservancy as a preserve design ecologist. At TNC, she recruited and organized a large group of volunteers who provided updated data on hundreds of California’s rare plants; before that, the only information known about many of those plants only existed on herbarium labels. At CNDDB, she oversaw staff who entered rare plant data into the system, helped develop several versions of RareFind, coordinated with Natureserve in ranking California’s rare plants, and co-authored the current Natureserve ranking scheme. Roxanne was educated at UCSB in Environmental Biology, and later, at Ohio State University, where she earned a Master’s in Botany. She also spent a year at the University of Arizona, Tucson, taking classes and learning about Sonoran Desert communities. Currently, Roxanne is a consultant, primarily performing monitoring of created and natural vernal pools in order to make sure mitigation is correctly implemented.
