Ernesto Chavez-Velasco, Scott Dunbar, Brian Peterson, and Brooke Wainwright

Ernesto Chavez-Velasco


Read more about Ernesto

I am currently pursuing a master's degree in natural resources at Cal Poly Humboldt where I'm researching commonly unused plant diversity in California grassland restoration projects. I completed my undergraduate degree from UC Santa Cruz in 2021, where I first gained research and restoration experience concerning California grasslands. Since 2019, I have been a restoration practitioner in Santa Barbara County and in Point Blue's Students and Teachers Restoring a Watershed Program in the Bay Area. Most recently, I was an assistant field botanist for CNPS in the North Coast bioregions. I also volunteer and participate in regional prescribed burn associations where I can apply "good fire" in our grassland ecosystems. I enjoy sharing my genuine appreciation and love for California's grassland systems for their often-overlooked beauty and their vital role in supporting the state's diverse flora and fauna.

Scott Dunbar

Alternate Member-at-Large

Read more about Scott

Born and raised in the rolling hills of southwestern Marin County, I developed a profound appreciation for open space and the ecosystems and ecosystem processes within. I am an alumnus of the University of California, Davis, having been awarded a B.S. in Sustainable Agriculture and Food Systems. Following graduation, I applied these skills to help manage the livestock and orchard component of an organic farm in Sacramento. Utilizing management-intensive-grazing practices, I developed an appreciation for the grasses and forbs that constituted the sustenance for the ruminants and non-ruminants I managed. While in a career transition, I stumbled across Holistic Management International, and participated in multiple trainings culminating in a whole farm/ranch intensive training class, which placed significant value on assessing an ecosystem as a whole to treat the root causes of a given management issue, rather than the symptoms. This aerial perspective of ecology was a profound shift for me in developing management tools to suit a desired outcome. After these realizations, I pursued, and was awarded, a Masters in Natural Resource Stewardship with an emphasis in Rangeland Ecology from Colorado State University. This program further instilled in me a management-forward approach to ecological stewardship grounded in a science-based approach. I have used this degree and my years of experience in management and advocacy for the past 2.5 years as a Stewardship Program Manager for the Marin Agricultural Land Trust where I manage our proactive stewardship grants programs and offer technical assistance, including dryland pasture management techniques, to Marin County farmers and ranchers. I have an enthusiastic appreciation for California and the rangelands and grasslands, and the managers here, however, I believe that there is always more to be done. I highly value the role of education, networking and collaboration in achieving a desired objective and I believe that the California Native Grassland Association is a crucial vehicle to increasing awareness and value on preserving, maintaining, and restoring native grasslands.

Brian Peterson

I have been the fire ecologist for Audubon Canyon Ranch’s Fire Forward Program since 2019, where I work to use fire for ecological benefit in the diverse ecosystems of Sonoma and Marin counties. I work with landowners to help plan and implement prescribed burns to meet a variety of stewardship goals and have designed monitoring protocols and experiments to better inform stewardship decisions. I am especially excited about using fire in grassland ecosystems to help increase botanical diversity. Two years ago, I initiated and organized a native grassland restoration and conservation working group in Sonoma and Marin counties to help connect people working to improve grasslands in those areas. I received a B.S. in Environmental Studies (2011) and an M.S. in Conservation Biology and Evolution (2014) from San Francisco State University. Before working at Fire Forward, I worked as a botanist for eight years with Nomad Ecology, doing rare plant surveys, monitoring rare plant and invasive weed populations, and mapping vegetation. During this time, I developed a deep passion for California’s grassland ecosystems and their botanical diversity. I would be excited to serve on the California Native Grassland Association board to help better connect projects from Sonoma and Marin counties to the greater state, work to help better educate the public on the importance of grasslands, and continue learning about grasslands from all of the amazing grassland experts in the organization.

Brooke Wainwright

Board Liaison to the Executive Committee

Alternate Member-at-Large

Read more about Brooke

I am a third year Ph.D. student at UC Davis studying the functional trait variation of California grassland plants with the goal of informing grassland restoration and management amidst a changing climate. I began working with and becoming enamored by California grasslands in my third year as an undergraduate at Cal Poly, San Luis Obispo. I continued to learn about grasslands and began restoring them as a preserve ranger in Kern County, California. There, I became passionate about investigating novel ways of restoring California grasslands to be more resilient, native-dominated, economical, and biodiverse. In 2021, I received my master’s from the University of New Mexico where I studied the recruitment dynamics of foundational desert grass species under a drier and more variable climate. At UC Davis I lead a student organization dedicated to connecting the Davis community to their local natural landscape and removing barriers to learning about and restoring these local ecosystems. I have been involved in leadership and committee work since high school and I enjoy working on a team toward a common goal.

Richard King


Rangeland Management Specialist, USDA-NRCS, retired

Read more about Richard

I have 36 years of experience in USDA-NRCS as a rangeland management specialist (and biologist) assisting landowners before retiring. I worked in Flagstaff, Arizona, for eight years and subsequently throughout northern California since 1982. I am a member of the Society for Range Management and strive to help the range profession shed its old paradigms because I know that rangeland health in California’s “annual” grasslands can be greatly improved. I believe: (1) that we underestimate how “native” perennial species on “annual” grasslands can be increased by mimicking the natural processes in which the perennial species evolved, (2) our “invasive species” are typically a symptom of biodiversity loss from past or current management, (3) planning livestock use based on perennial species vigor and reproduction remains the most misunderstood and underutilized tool for grassland management and “restoration”. Since 1991, I have enjoyed raising grass-fattened beef, building biodiversity above and below ground, and watching “native” perennial grassland species increase on 40 acres that were part of my great-grandparents’ farm. I’m excited that genuine shifts in long-held paradigms are steadily occurring in California as people become better observers of what’s happening on the land and how livestock can be used to improve soils, land health, and wildlife productivity. I’m a Certified Rangeland Manager with the California State Board of Forestry and Fire Protection and the Society for Range Management. I’m also a Certified Holistic Management Educator with both Holistic Management International and the Savory Institute. My passion is helping others learn this new framework for decision-making that will simultaneously address the complexity of managing land, people, and money successfully, both short-term and long-term.

Justin Luong

Research, Science & Education Committee Chair

USDA Postdoctoral Fellow, UC Davis, Department of Plant Sciences

Read more about Justin

I am a researcher at UC Davis. I focus on restoration in California, specifically how future extreme droughts may impact newly planted natives and how that drought may affect and interact with competition from non-native species. My work is aimed at determining mid-to-long-term outcomes of grassland restoration projects up to 30 years post-restoration ranging from Santa Barbara to Humboldt. I also consult for various non-profits and manage a grassland ecology internship program started in 2017 to present, first out of UC Santa Barbara then UC Santa Cruz and now Davis where I provide mentorship for interested students. I previously worked as a field coordinator for the Cheadle Center for Biodiversity and Ecological Restoration (CCBER) at UCSB overseeing grassland and vernal pool restoration. I love California grasslands because they are unique, underappreciated and they host a wide diversity of flora and fauna. On the board I work within the Conservation, Education and Outreach committees to advocate for the protection of our beautiful native grasslands.

Kendra Moseley


Certified Range Manager

Read more about Kendra

Kendra is a Certified Range Manager (CRM) #120 on California forested rangelands and an ecologist working on soil-site relationships, nonequilibrium dynamics and resistance and resilience concepts throughout the West. She has over 15 years of experience working with native plants, native plant ecology, and adaptive management, conservation, and restoration. She got her B.S. in Rangeland Ecology and Management (RE&M) with minors in Botany and Biology, and her and M.S. in RE&M with an emphasis on Restoration Ecology both from University of Idaho. Her M.S. project focused on developing a training module for Idaho Transportation Department (ITD) employees on the value and practice of using multiple functional groups of native plants and soil amendments to improve roadside revegetation across the State, as well as finishing the ITD Roadside Revegetation Handbook, continuing their research on using nurse crops to assist native plant establishment in roadside seedings, and native plant germination trials to identify best/cost-effective species for seeding success on roadsides. After graduating, she got a job as Research Faculty at University of Nevada-Reno in the Plant Ecology Department working on a 4-state native plant restoration project in cheatgrass-infested sagebrush grasslands. Kendra has dedicated most of her career to this ecological work because she believes that having a better understanding of the patterns and relationships that exist between soil and site characteristics and how they drive vegetation expression and their ecological dynamics is crucial to the success of all land management objectives, including the conservation and preservation of important and continuously threatened ecosystems like California native grasslands.
