At the moment the Arborist ist not very useful in any game stage especially in late game.
Atm i have 2 T2 Barns with 12 cows each plus a cheesery. With this i produce about 1800 Cheese, and can slaughter ~3 cows (additional 1500 meat).
With this setup i produce ~3300 Food per year, i need 4 Pops for the barns, 6 for the cheesery and 1 for the wheat field for the food (11 workers). The space for this is round about 2 Arborists
One Arborist produce about 200 Fruits per year, after some years u must manually replant the fruit trees and because the workers need time to plant the trees it takes even more time for the Arborist to get full efficient again. So i cant see any advantages for focusing on Arborists (ok u need fruits for t4 Housing)
My suggestions for it:
buff the amounts of fruits u get
add more workers that water the trees to keep the fertility high. (build a well nearby for better efficiency)
add a “plant” and “auto-replant” option. If you built the building, set the radius where u want. Than set the ratio of the trees (like the Fletchers where u can set the Arrow/Bow ratio) than click “plant” and the system adds trees in this circle.
maybe slower grow time for the trees but much longer lifespan (like in real life)
maybe use fertilizer to boost the yield for a few years (like +40% in year 1, 30% in Year 2 ans 15% in year 3)
Trees produce waste for the compost (maybe spoiled food too? Time for a Tier 2 compost)
I think it actually does improve fertility where the cattle graze. Heard it somewhere and testing it out now. If it is not the case then definitely an improvement to the game mechanic we can suggest. Overgrazing is not affecting the grazing quality currently, also a suggestion one can make.
I think the fertility for trees and crops are different though. So expanding the option of adding fertilizer to trees, and possibly having cattle graze in between, might be nice.
[Update] The fertility of the grazing area definitely goes up and grazing quality definitely goes down. So this works as expected. Now to see if grazing quality recovers over time.
It affects the fertility for farming but doesn’t seem to affect the fertility shown when placing an arborist building. At least it didn’t last time I tried.
An issue I have with the arborist is the circular area of work on a grid layout.
It’s very hard to tell at the borders whether a tree actually falls within the work area or not.
I thing the grazing area of the barn and the working area of the arborist should be inverted.
