Tree Condition Surveys and Risk Assessment
Trees are fundamental to our wellbeing and quality of life, whether in an urban or rural context. They secure many environmental, economic and social benefits when planted in appropriate locations and properly managed.
However, their potentially large size and proximity to frequently used areas mean that trees can pose a risk to nearby people and property. Although tree-related fatalities are very rare, tree owners have a legal responsibility to ensure their trees do not pose an unacceptable risk. The National Tree Safety Group has published further guidance for landowners; read all about it here.
Tree assessments are mostly carried out from ground level with the aid of measuring tools and aids to investigate basal or stem defects, but we can provide aerial inspections of trees as well. The information for each tree is recorded on a handheld computer enabled with GPS so that trees can be plotted on digital maps or exported to client’s GIS software.
Tree condition surveys focus on the health and condition of trees, making recommendations for good tree management based on the physiological and structural condition of the trees and local environmental conditions.
Tree risk assessments take this survey a step further, considering the use of the site and the potential for harm if a tree were to fail. We use robust and defensible systems for assessing risk including Quantified Tree Risk Assessment (QTRA), VALID and our own bespoke tree risk assessment methodologies.
