after about four years it dries up
None. Cattle farmers (or ranchers) do not operate within the forest itself. They raise their cows outside of the forest where the grass grows...which is where their herd of cattle eat the grass.
When farmers plant new grass on burned grass, the new grass will start to grow and cover the burned area. The new grass helps to prevent soil erosion, restores vegetation, and provides feed for livestock. It can also help the ecosystem recover after a fire event.
It means that everybody has left White Forest. You just need to go back to Black City and get people into White Forest again. Hope that helps.
usually...
They eat ranchers grass that their cattle eat, and they "ruin" water holes.

You have to see grass and then go in the grass and battle. It is usually Elekid for me but try to get a Pokemon in White Forest. If there is no grass then you can't catch Elekid and other Pokemon so just try to get grass. :)
