Jim Chance, B.S., Rangeland Specialist

Mr. Chance is a successful rancher with more than 40 years of experience ranching in California and Colorado. He received his B.S. in Agricultural Business Management from California State Polytechnic University, San Luis Obispo in 1961.

Mr. Chance owns more than 30,000 acres of ranchlands in northern California and Colorado, and is thoroughly familiar with all aspects of ranching. He brings to our consulting team invaluable knowledge regarding practical considerations of range management and ranching operations such as ranching economics, type of ranching operation (cow-calf, stocker, dairy heifers), season of use, grazing intensity and rotation, and livestock carrying capacity.

Mr. Chance is also familiar with the biological resource and conservation issues pertaining to ranching in an annual grassland environment, especially in regions with vernal pools. His ranches in Merced and Solano Counties incorporate more than 15,000 acres of high-quality vernal pool habitat as mapped by the California Department of Fish and Game. He has placed both of these ranches under permanent conservation easements. For the past three years, he has worked closely with John Vollmar and biologists from The Nature Conservancy to understand the resource issues on his ranches and implement grazing practices that consider the needs of resource conservation as well as economically-viable ranch management. Through the years, Mr. Chance has served as a Board Member of the Ballico (Merced County) Soil Conservation District, President of the Denair (Merced County) Farm Bureau, and Chairman of the Marketing Committee for the California Cattlemen’s Association.

Jon Kelsey, B.S., Botanist

Mr. Kelsey is an agronomist and vegetation ecologist with over 20 years’ experience. His background includes botanical work, vegetation assessment, geologic work (specifically particle analysis and distribution in sedimentary deposits), soil assessments, and geo-morphologic descriptions including associated plant communities. Mr. Kelsey received his degree in Agronomy from California Polytechnic University, San Luis Obispo in 1978.

Working as a botanist, Mr. Kelsey has conducted floristic surveys in conjunction with mined land reclamation plans, and rare plant surveys involving vernal pool, annual grassland, and oak woodland habitats in the San Joaquin Valley and adjacent Sierra foothills. Mr. Kelsey participated in the botanical field surveys for the ecological study of eastern Merced County’s vernal pool landscapes. Mr. Kelsey has prepared reclamation plans which have been approved under the State of California Surface Mine and Reclamation Act and continues to actively advise on such projects. Mr. Kelsey’s expertise in the area of biomorphology is a result of extensive fieldwork, since 1989, involving geologic assessments in the lower Sierra Nevada foothills, identification of their associated soil types, and plant inventories in those areas. He has worked with landowners involving grant proposals, habitat and land form characterizations, plant surveys, regional conservation planning, mitigation banking and conservation easements. In 1992, Mr. Kelsey founded Merced River Mining & Reclamation Corp., a company which specializes in aggregate production from dredge tailings, reclamation of mined ground, and botanical reports. He has worked with botanists conducting rare plant and floristic inventories and bio-geographic research projects involving yearly data collection at project sites.

Mr. Kelsey currently is a Director on the East Merced County Resource Conservation District. He also is a member of the Board of Directors of Merced County Farm Bureau.
