Unlimited Trees Mod v1.12


Current code by BloodyPenguin and mod site hosted by DRen72
Latest Code Update: May 24, 2018 (Compatible and tested with v1.12.2 and Campus DLC)

This mod unlocks the games limitation of 262,144 trees to allow you to use just over 2 million.
(Be aware that adding this many trees can slow down your game depending on your hardware, so be ready)

This should also work in the map editor. Feel free to share comments or report issues.
Highly recommended combined with BloodyPenguins 81 Tiles Mod.

Works in all Expansions!

Note from DRen72: As of May 2018 I am excited to announce that BloodyPenguin has joined us in working on this awesome mod. I am one of those Cities Skylines players that HAS to have a lot of tree coverage. I believe in the mod, happy to support it and am excited to see it continue, now with BloodyPenguins help!


Configuration file option in the game menu. This setting now controls the number of trees allowed in chunks of 262144. Valid settings are 4 (default),5,6,7 & 8 (4 == 1million, 5=1.25million ect.)

Acknowledgements: DRen72 and BloodyPenguin & knighthawkGP would like to thank Sebastian Schöner for his Cities Skylines Detours project code which is used in this mod and makes it possible. His site is located at .

We would also like especially thank Mabako for developing the original project and allowing it to be reused by us. Sincere thanks guys!

INCOMPATIBLE WITH: BloodyPenguins Tree Snapping Mod.

@BloodyPenguin can you help us out?

Apparently it appears to load burning trees in a loop, a never ending loop

Got the same issue as the 2 posts below. Broke my save yesterday and haven't been able to get around it.

Same error as below, was working until now, broke the save, trying diffrent settings and did not help

Seems to be an issue:

[TreeUnlimiter:CustomSerializer.DeseralizeSaveDataContainer] We could not find our named byte array. No extra burningtree data to process
as well (TreeManager) tag mismatch

Only used 206000 trees in latest save. of 7 types. and still get the error.

First of all thanks for the great mod, it works as it should.

Is it possible to increase other limits, network (nodes, lanes, path)? With more than 25 tiles this would be very useful. Thanks for reply!

It's time to plant 20 000 000 trees in Cities: Skylines

Get rid of Tree snapping or unlimited trees. Both together cause floating trees on every load.

I have floating tree issues everytime Ioad into a save game with this mod. anyone else have this issue where all of the trees are floating in the sky

@BloodyPenguin any idea when there will be an update to make Tree Snapping compatible? It's been quite a while since I started using this mod and for the entire duration it has said that an update is coming in the 'near future'. I don't want to pressure you, but how long would that be?

Reason is I'm working on a Japanese city series for YouTube and I absolutely need Unlimited Trees Mod, however I also work a lot with fake surfaces and would love to be able to decorate those with trees or bushes.
