At least part of that is the climate. A forest in a tropical zone is so efficient at processing nutrients that the soil beneath a forest is almost nutrient-free; the nutrients are always moving from plant to plant. If you take off the forest, what is left is not very hospitable and erodes easily. Temperate forests accumulate humus; remove the trees and there are nutrients sitting there waiting to foster new growth. (IANA forestry expert...) |
