We recently undertook work on a 40m high Silver Fir. Neighbouring trees were blown over and this left the tree above the surrounding canopy and exposed to future storms which could have caused a lot of problems.
The solution was to retain the tree within an acceptable level of risk with a 30% crown reduction leaving a viable tree of stature but with far less ‘wind sail’ and a lot less susceptible to future storms. This meant some serious climbing but a job well done in the end!
