When to research
This Imperial Age upgrade is suited to a long Wood shortage with a protected group of Villagers able to keep logging. It raises tree and Mango Grove gathering by 40%, but costs 1,000 Food and 1,000 Coin and takes 30 seconds. If the forest is nearly gone or late-game units need those resources immediately, the percentage cannot recover its cost.
A large bonus for logging
Pine Tree State increases Villager Wood gathering from trees and Mango Groves by 40%. It does not raise gathering from other resources or construction speed. The upgrade rewards sustained access to safe logging sites.
State Capitol research
The United States researches it at the State Capitol in the Imperial Age. It costs 1,000 Food and 1,000 Coin and takes 30 seconds. Consider the Wood demand that remains after the research before choosing this over military production.
