Document Description
The Mariposa Grove Road hazard tree and biomass removal project mirrors the Mariposa County SSARR Fuel Reduction and Biomass Utilization project. The primary goal of the project is to remove hazard trees and biomass up to 200 feet from the road corridor. Small diameter green trees (<20"DBH) or hazard trees will be fallen. Biomass may either be transported offsite or converted into biochar through a portable biogen plant staged at one of several ? locations in the park. The work is critical to meet the public safety and tree disposal needs stemming from widespread tree mortality in the southern Sierra Nevada. The project protects infrastructure and increases public safety by removing hazard trees and thinning fuels on critical corridors. It also protects communities located within the Wildland Urban Interface, specifically Fish Camp and Wawona. This project also creates a fuels break in the event of wildland fire or if a prescribed fire is to be conducted. No work will be done within the bed, bank or channel of any existing drainage, or culturally sensitive sites within the project areas.
