In detail
Staiši Oak is a large oak tree in a comparatively good state and we can hope that in the future it will be one of the largest trees in the region. the circumference of the trunk at the height of 1.3 m in July 2018 was 8.47 m.
Former measurements from the 1980ies and 1990ies were below 8 m: even 7.3 m, thus the tree increases in size.
