All of the traits that contribute to creating a monodominant forest over time hinder the growth of other plant species and force them to move to a more mixed forest. Even though this is inconvenient for the plant species that were there, there has not been any evidence that suggests that this is a negative effect of monodominance. Monodominant forests are also found to have significantly less nitrogen in their soil than mixed forests. In these monodominant forests there are a lot of dominant tree species from the legume family that have nitrogen fixation. Nitrogen fixation creates compounds that help a plant to grow in otherwise low nutrient conditions.
