I reckon it’s an AI bug.
The trees are scaled to be about 20% taller than adjacent buildings. That’s fine for the average 1 or 2 storey house.
However for a 50 storey skyscraper 20% taller is crazy.
Its bad coding. The building height is known and a min/max tree height should be applied to keep within nature’s limits. Should be easy to fix in the next data crunch.
There also seems to be too many evergreen trees in the UK data. It’s winter, we have had frosts already.
