No we dont. This is a professional map and the pokemon developer (unluckily) decided to use it as a base layer for your game. We do only map real objects and here I cant really see that gigantic tree. I do see some of them but they look all inside some private backyards, even if I would do add it, I don't think you could reach it.
That said you should understand that your game uses a 6 months old version of out map and then adding things like this one wouldn't affect your game. They are not planning any map update, I think you should be happy with the features that are already on the map.
