Correlation of wind speed and root plate tilt of trees in urban environment
Tilt of > 0,2° at wind speed of 50-60 km/h leads to critical tilt values at gale winds.
Research notes on tree assessment and tomography
Tilt of > 0,2° at wind speed of 50-60 km/h leads to critical tilt values at gale winds.
Often, the stem surface of mature London plane trees is bumpy. Our results, derived from a thorough characterization of the stem surface, tomography, and thermography, show that this does not indicate inner defects.
Our data do not support the use of a threshold value of slenderness in tree risk assessment.
In spruce, the effect of slenderness on maximum bending moments is negligible.
