Centuries-old trees across Istanbul's historic groves, Bosporus hillsides and protected natural sites are being preserved through detailed survey plans and advanced scientific techniques that help identify structural risks before they become hazardous.
Experts say the studies, which document each tree's physical characteristics and health, play a key role in protecting the city's centuries-old natural heritage while ensuring public safety.
The first stage of the process involves preparing survey reports that serve as identity records for each tree. Information including species, age, height, trunk diameter, crown width, health condition and geographic coordinates is recorded, alongside details such as disease, fungal growth, monumental value and conservation requirements.
The data is then transferred into digital mapping systems, creating a comprehensive inventory that guides future maintenance and preservation work.
The reports are also used to determine whether trees require pruning, mechanical support, removal of dead branches or, in rare cases, removal for safety reasons. Any intervention involving trees in protected natural sites must be supported by expert reports and approved by the relevant authorities.
