About Us

At ECI we are vegetation management consultants, providing services to public agencies considering using animals as a natural method of removing undesirable plants. We work with fire agencies, municipalities, and government entities to implement fire fuel reduction programs. Our 24 years of experience and professional knowledge make us the leaders in this field.

Our environmentally friendly technique is used throughout the year for:

  • fire prevention
  • weed and undesirable plant control
  • public safety, by providing visibility in public areas
  • enhancing native, perennial plant populations by removing annuals and brush
  • clearing utility right-of-ways, levees, and making defensible space for fire breaks

Our approach is completely natural:

  • enhances wildlife habitat
  • uses no toxic chemical sprays
  • requires minimal manpower
  • chain saws and mechanized equipment are not used
  • no pollution or loud noises that disturb the environment


Dr. Debrann Brea McGrew

Dr. Debrann Brea McGrew is a licensed veterinarian with a masters degree in comparative pathology. She received her training at the University of California at Davis and has had a private veterinary practice since 1983. Her area of expertise is in herd health, serving ranchers and farmers throughout the western states.

Dr. McGrew has studied managed grazing techniques for many years with several animal species on a variety of biotypes. She has paid attention to animal behavior and “trains” the animals that are used for grazing projects. Importance of animal age and forage consumption is considered in the herd. Because she has worked with multiple-species grazing, she has observed different diet (forage) preferences among species. She has the experience to make recommendations for and to manage multi-species grazing to maximize forage utilization and achieve superior grazing results.

Robert McGrew

Robert McGrew was a professional firefighter in northern California since 1973 and retired from the Sacramento Metropolitan Fire Department to run ECI full time. His experience enables him to contribute valuable knowledge of priority grazing patterns from the viewpoint of the inherent nature of fire.

Robert was raised on a sheep ranch and has been involved in ranching his entire life. He has used managed grazing techniques with portable fencing and water systems for over 40 years. He is remarkably adept at designing and building corral systems which enable quick removal of animals from grazing sites. His knowledge of water systems allows water for livestock to be provided in an efficient and readily available manner.
