There are different numbers of jobs available in different regions. Each peasant takes up one job, each sapling four jobs and each tree eight jobs. Under "max. trees" you can see how many trees/saplings would take up the entire space for "field labourers". But even the densest forest yields enough fruit, roots or mushrooms for a few people to make a living. 10% of the jobs in a region, but no more than 200, are therefore never blocked by trees or saplings. If the number of available jobs is exceeded, no more player units can work in this region.

In glaciers, swamps and deserts, road construction is only possible if there are special buildings.

*From a total number of 600 trees and/or saplings, a level is considered a forest
