Randy Jacobszoon

As President and Principle Registered Professional Forester (RPF), Randy is the manager of over 20,000 acres of private non-industrial forestland throughout Mendocino, Sonoma, Lake, and Napa Counties. As a California RPF he has been involved with the management and protection of forest lands as a resource and land manager for over 30 years.

With an extensive background in forestland management and timber harvesting, his major fields of emphasis include forest resource planning and management, timberland appraisal, and land use planning and development.  Principal projects completed over the course of over three decades have included the writing and administration of long-term forest management plans, timber inventory appraisal and analysis, and sustained yield planning and management. Randy has also gained considerable experience in the development of timberland conversion applications and plans, mitigated negative declarations, and feasibility studies for wineries and individuals, for vineyard location and design. 

Prior to establishing Jacobszoon Forest Consulting, Randy worked as an Area Forester for a large timberland owner where he designed and administered the forest planning and management of a 24,000-acre timber tract. Duties also included the designing, monitoring, and development of mitigations for stream, wildlife, and watershed restoration projects.

Immediately out of college, Randy started a small logging company based in Fort Bragg, California.  During the 10 years as a timber operator, principal projects included the design of road systems, tractor yarding operations and cable yarding systems. The company also operated a mobile sawmill, manufacturing custom lumber for small landowners and supervised the planting of over 100,000 conifer seedlings each year.
