Hi Robuster.
I noticed that this changeset added many trees on this campus, but a lot of them don't make sense. For example, see https://www.openstreetmap.org/note/4932050 : you added 18 trees where there are actually only 8.
Similarly, you added 11 trees in polygon https://www.openstreetmap.org/way/704728986 but it's actually a bamboo grove, so there's not a single tree there.
Also, all the trees are marked as "lit", which is wrong (there might be a couple of trees with fairy lights on this campus, but that's it). And you marked most (all?) of them as "broadleaved", which can't be inferred from aerial imagery (I assume this all was inferred from aerial imagery).
natural=tree is used for mapping single trees, sometimes because they are significant. Please only mark trees from aerial imagery if single trees can be told apart, or even not at all if you can't verify on site. Please do not map trees from aerial imagery for a dense area of greenery as it is guaranteed to be inaccurate. There are alternatives, for example natural=wood if the area is significantly large.
