The trees are not from the River, they are from the Mesa Plateau, Trees are sometimes overlapping into other biomes (e.g. snowy jungle trees between Taiga and Jungle)
Thanks for the clarification. I updated the title and the description to avoid confusion.
Is this still a concern in the latest Minecraft version 13w48b? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
This ticket is incomplete without the requested information, no response has been received within a reasonable time and we are assuming the issue has been resolved. If you are still experiencing this issue, we can reopen it at your request.
Please review the guidelines before reporting issues.
The bug is still present in 1.11.2.
Is this really a bug? That's part of the river biome, it's just less noticeable in other biomes because they are generally lower/flatter and already have grass and trees. The only way to fix this is adding a new river sub-biome that would spawn inside mesas, but that's more of a feature request rather than a bug report.
Confirmed for 1.13.1.
Confirmed in 1.15.2 and 20w22a.
Confirmed in 1.16 Pre-release 2.
Confirmed in 1.16-pre4.
Confirmed in 1.16-pre5.
I believe this might be intended because rivers sometimes spawn trees, like trees generating in deserts with a river and trees generating in mushroom shores with oceans. Give your opinion if you think this is a bug. It might be 50-50.
Forward-resolving to more generic
