CLP provides training and educational opportunities to Maine Loggers. The program is committed to recognizing the skill and professionalism of those who meet and exceed our standards. 

The CLP program is based on the following standards: 

  • Safety,
  •  Skill, 
  • Knowledge,
  •  Stewardship, 
  • Professionalism 
  • and Pride.   

The program takes pride in the fact that loggers’ accident rate is half what it was when the program began.  As a result, CLP loggers pay up to 59% less for Worker’s Compensation than non-certified mechanical loggers.
