This book enables everyone, who is responsible for tree protection, to come to a sufficient professional expertise. It is based on long term studies and assessments by the authors. This book helps to assess static circumstances via Static Integrated Assessment (SIA) and security management for tree workers. A professional tree inspection based on static rules helps to extent security and lifetime of trees to keep control cycles reasonable and costs short. This is a comprehensive manual about trees for urban green space planning officials, experts, and planners and practical users.
