    Preserving Ecological Diversity

Northern California Biological and Botanical Consulting

Northern California is rich in natural biodiversity. This biodiversity stems from unique variations in natural and manmade landscapes throughout the region. Wisely conserving and managing the landscape enures the many values offered by the region’s resident plant and wildlife benefit both public and private interests alike. 

With more than 12 years of supporting private, non-profit, and public projects with biological and botanical research, surveys, and assessment, Jacobszoon and Associates, Inc. has taken a leading role in the conservation, management, and mitigation of our unique plant and wildlife. Our team of biologists and botanists support a diverse project portfolio including the development and monitoring of conservation easements, Timber Harvest Plans (THPs), Non-Industrial Timber Management Plans (NTMPs), timberland conversions, rural land development, Lake and Streambed Alteration Agreements (LSAAs), and other California Environmental Quality Act (CEQA) and CEQA exempt projects with riparian habitat assessments, on-site monitoring for in-stream projects, preparation of biological and botanical assessments and reports, and construction monitoring. 

The biological and botanical team at Jacobszooon and Associates, Inc. enures a balanced approach to development and community needs and has developed numerous mitigations, re-vegetation, and long term management plans, throughout Mendocino, Lake, Sonoma, and Napa Counties.
