Individual trees are fine, just more work. It can be difficult to separate the trees from the forest when the trees form a canopy. Rows of trees are common along fences, roads and paths in cities.

Fixed. A street lies on the Jacka/Taylor admin border which is the source of the error.

I can see what has happened and will fix it.

This change set should not include changes to the administration boundaries for Jacka / Taylor. Are you say the boundary was moved, or that a relation was removed from the boudary line (the line can be used in multiple relations). The relation for the admin boundary should not have chaged. Thanks for your email. I will make some checks.
