California Consulting Botanist Certification

Professional certification for field and consulting botanists is good for the profession and good for the environment. Certification helps ensure that the most qualified people conduct California's environmental reviews and that our decision-makers have the information they need to make sound land-use decisions. That's why CNPS and other leading botanical organizations have partnered to create a new consulting botanist certification to formally recognize botanists that:

  • Incorporate scientifically sound botanical principles in decision-making
  • Meet a minimum set of standards in knowledge and experience
  • Adhere to high ethical standards
