Jason Dart, B.A.

Principal Scientist


Jason has been with the A&M team since the company’s inception in 1999. Jason’s professional expertise span the range of natural resource science and environmental planning, from restoration ecology to rare plant taxonomy, endangered wildlife surveys and managing complex permitting projects in California.  He has experience with numerous listed wildlife species, is a recognized expert botanist with the flora of Central California, and is particularly interested in large-scale biological inventories. 

In 2014 Jason became the Environmental Compliance Manager at Topaz Solar Farms, a 550 mega-watt industrial solar project in San Luis Obispo County.  He successfully managed environmental compliance for the project through completion of construction and final close-out with the County.  Throughout his nearly 10 years working on the Topaz project, Jason managed biological surveys, prepared technical reports for CEQA and NEPA, worked through ESA Section 7 consultation and CDFW Incidental Take Permit (ITP) processes, and coordinated with innumerable contractors and regulators to keep the project compliant on conditions for air quality, noise, transportation, biological and water resources, cultural resources, hazardous materials, and more.  


In 2015 Jason started work on the California Flats Solar Project in Monterey County, initially managing large-scale preconstruction survey efforts, continuing with management of daily biological monitoring teams, and culminating in a position as Environmental Compliance Manager for the General Contractor, McCarthy Building Companies where he continues to provide daily compliance management.  Mr. Dart is proficient in the study and reporting  of ornithology, mammalogy, botany, wetlands, conservation and mitigation plans, wildlife assessments, and protocol level surveys including San Joaquin kit fox, bat, steelhead and California red-legged frog surveys.
