Guidance Notes Bundle

Tree Inspection Bundle GN4 :Visual Amenity Valuation of Trees and Woodlands (The Helliwell System) GN11: This Guidance Note provides a comprehensive answer, setting out all the information that may be required when carrying out an aerial inspection. GN:7: A greater understanding of trees and growth in the use of computer technology and technical instrumentation may contribute to improved accuracy of tree surveys, but it remains that the basic requirements of surveying must be clearly understood. Whilst this Guide does not provide detailed procedures for tree inspection, or replace the range of existing guidance on tree health and condition, it seeks to assist the tree surveyor to clarify survey objectives, know where to find appropriate information, ensure that they meet their duty of care and identify opportunities for the use of technology to assist with collection, storage, and presentation of data.
