Forests have the most biological diversity in terrestrial ecosystems and provide vital ecosystem services to humans. They are among the most valuable terrestrial ecosystems that provide various services and goods, including protection of water resources, soil, biodiversity, gas regulation, and production of wood and non-wood products. These ecosystems can maintain fertility and essential elements for plant growth such as nitrogen, phosphorus and potassium by reducing soil erosion. Ecosystem services represent the goods and services that result from activities. The Millennium Ecosystem Assessment (MEA) considers ecosystem services as equivalent to "benefits". The first macro-scale ecosystem assessment system is the MEA approach. In the framework proposed by this approach, ecosystems are seen from the perspective of the services they provide to society, and ecosystem services are the benefits that people get from the ecosystem. MEA has categorized these services into four categories: supporting services, provisioning services, regulating services, and cultural services, with the aim of creating a connection between ecosystem services and their human well-being.
