The first part is an overview of the lightning started Milli Fire that was first observed on August 11th, 2017 and was 100% contained by September 24th, 2017. This first part covers broad-based landscape statistics and provides background and context to Parts 2 and 3. Part 2 covers specific developed recovery projects and project statistics coordinating to the projects and Part 3 covers silvicultural marking guides/ procedures that would be utilized for project implementation. In this way this document serves to provide planning to implementation information 2 TABLE OF CONTENTS Table of Tables
