The researchers studied the plant life in a specific area of Ayubia National Park in Pakistan to understand how different factors like soil type, pH, and tree density affect the types of plants that grow there. They found that these factors play a major role in determining the variety of plants in the forest. The study used statistical analysis to show the relationship between the environment and the distribution of plant species. The findings help us understand how different environmental factors influence the types of plants that can thrive in a specific area.
