The researchers studied plant diversity in vegetation restoration on Tudiling in Mao County, China. They looked at different types of regeneration and disturbance levels in 54 plots. They found 242 plant species in total, with certain families being more common. The vegetation was divided into 6 major types based on natural and artificial communities. Forests had more distinct layers and higher diversity than shrub communities. Species richness decreased with higher disturbance levels, especially in artificial communities. Heavy disturbance reduced diversity and hindered tree regeneration. Species diversity was higher in slightly disturbed forests. Using diverse plant species in restoration can help maintain high diversity and richness.
