CalVTP Field Training: Sierra Foothills, Vista Del Rio Project 

Wednesday, November 1st, 2023, 1:00pm - 5:00pm

This was an opportunity to learn about a fuel reduction project at Vista Del Rio in Oakhurst, California. Participants increased their understanding of how CALFIRE used the CalVTP at Vista Del Rio to facilitate vegetation management and fuels reduction. 

Participants completed a field treatment tour of the project area, learning about the different treatment methods used and why they were chosen. Sebastien Cordier, Madera-Mariposa-Merced Unit Environmental Scientist at CAL FIRE, and Brian Mattos, Madera-Mariposa-Merced Unit Forester at CAL FIRE, discussed the need for this project, how the treatment zones were selected, and the successes as well as the shortcomings that happened while implementing this project
