There are two plowed fields that are each one acre and one mile apart with a wood surrounding one and the other surrounded by a pasture; they have the same soil composition and climate.In the first field,as succession begins,the pioneer species are pine trees and shrubs.In the second field,the pioneer species are weeds and shrubs.This provides evidence for which model of succession?

The fact that different pioneer species colonize each field suggests that the soil and climate are not the primary driving factors of succession. Instead, the tolerance model suggests that the initial conditions of the site determine which species can establish and thrive, as certain plants are better adapted to compete for resources in different environments. In this case, the first field may have had more resources available for woody plants like pine trees, while the second field may have had more resources for weedy plants.
