Preserving the Turkey Oak of Heligan Gardens
In 2021, Jason was commissioned to carry out an assessment of a 200-year-old Turkey oak at the Lost Gardens of Heligan- a tree showing signs of decline and being considered for removal.
Using advanced internal decay detection equipment, Jason was able to accurately assess the tree’s structural condition. The findings showed that, rather than being removed, the tree could be safely retained through a targeted reduction of weight within the crown.
As a result, the tree was preserved, protecting both public safety and an important part of the site’s historic landscape.
