What is the role of site history in assessing tree risk?

The role of site history in assessing tree risk is crucial as it provides context regarding the conditions and events that have affected a site over time. Understanding past disturbances—such as storms, pest infestations, or land management practices—can greatly inform current risk evaluations of trees. For instance, if a site has a history of soil erosion or root damage from previous disturbances, it may indicate that the trees in the area are at a higher risk of falling or becoming unstable due to compromised root systems.

Additionally, knowledge of past diseases can help assess the likelihood of recurring issues that could affect tree health and stability. Geological changes, such as subsidence or shifts in topography, also play a significant role as they can influence tree stability and risk. By comprehensively understanding the site's history, tree risk assessors can make informed judgments about potential hazards and prioritize management strategies accordingly.
