Selective thinning is a forest management practice that involves removing specific trees to improve the overall health and growth of the remaining trees. This technique helps to reduce competition for resources like sunlight, water, and nutrients, allowing the selected trees to thrive. It can also enhance biodiversity by creating more open spaces for various plant and animal species. This method is often used in conjunction with other forestry practices, such as sustainable logging and reforestation. By carefully choosing which trees to thin, forest managers aim to create a balanced ecosystem that supports both economic and environmental goals.
