The Forester from Minecolonies cannot chop the Nest - like Oak Nest - from the trees logs. Would it bee possible to add something like a option in the config, that the nest cannot spawn in specific trees ?

Adding the nest blocks to a tag at data/minecolonies/tags/blocks/tree.json would allow the forester to chop them down as part of the tree.

I added them to minecraft:logs not too long ago which is included in the minecolonies tree tag.

well... when it is this simple - thank you :-D

Which radius for the flowers is needed around a tree that a nest cannot spawn?

Don't have flowers near the tree farm

it's a 2-3 blocks radius around the sapling that has to be clear of flowers

thinking about it, cherry leaves are considered flowers, so I can see an issue growing those

mangrove propagules are also flowers, which is just silly

But Oak, birch, spruce, jungle are not?

No just the mangrove

I added them to minecraft:logs not too long ago which is included in the minecolonies tree tag.

the forester still ignores them

well then there's nothing I can do about it, adding it to the tag should pass this check but if it's still not considered part of the tree then it's on them to fix
