He began his CONAF career in 1976 as an Aerial Observer and Dispatcher and in 1979 as the Chief of Fire Management for the Santiago Metropolitan Region. He was also the national Chief of the Human Resources for 8,000 employees, where he restructured that department.

He has participated in technical meetings, conferences, and trainings in Chile, US, Canada, Portugal, Spain, Brazil, South Africa, Argentina, and Italy, and has authored over 50 publications on how to prevent and control wildfires.

Herbert has an MS in Human Settlements and the Environment from the Catholic University of Chile, as well as degrees in Phycology and Forestry Technology.

As such, Herbert has a wide range of skills including fire suppression, prescribed fire, risk management, WUI community wildfire prevention, communications (especially in Spanish), policy, and HR.  

Dave Kahan

Forest Health Specialist


Dave has been working towards wildfire resiliency and for sustainable forestry since 1981. He has a strong affinity for a healthy ecosystem, striving to balance both ecological and economic sustainability. Dave spent four years on federal Hotshot wildfire crews, and 22 years as a privately-contracted hazard tree faller. He has worked on wildfires in every western state except Hawaii, as well as Tennessee and North Carolina.  

Since 1987, Dave has designed and implemented more than 20 miles of regionally strategic shaded fuel breaks, and many dozens of defensible-space projects for his neighbors in northwestern California. This was accomplished with his crew at Full Circle Forestry, the company he started in 1991. Among his experience, he planted trees commercially for 20 years, built and maintained trails on federal lands for four years, and received his California Timber Operator License (LTO) in 1991.

Dave has served on the Boards of Directors of the Institute for Sustainable Forestry, Mattole Restoration Council, and Telegraph Ridge Fire District. He has authored many articles and given countless presentations and workshops on various aspects of sustainable forestry and wildfire resilience.

Since witnessing the devastation and “modus operandi” of the Wine Country fires of 2017, Dave has focused much of his recent efforts on educating residents on the crucial importance, and inter-relatedness, of fire-hardened buildings and defensible space.

Cameron is a landscape ecologist studying disturbance dynamics (e.g. fire, insects, drought), ecosystem resilience, and human-environment interactions in temperate forest and grassland ecosystems. He uses remote sensing, dendrochronology, spatial analyses, statistical modeling, ecophysiological methods, and field data to integrate research over long time scales and a range of spatial scales.


He has worked extensively in the Rocky Mountains in the US and Canada, and in several temperate forest regions of the southern hemisphere, including Patagonia, Tasmania, and New Zealand. He earned a BS in Ecology and Evolutionary Biology from Rice University, an MS from the Division of Biological Sciences at the University of Montana, and his PhD from the University of Colorado, Boulder. He was recently a post-doctoral scientist at the Department of Forest and Conservation Sciences at the University of British Columbia, and is currently a research associate in the Forest Ecosystems & Society department at Oregon State University.
