Forest is a city located in Belgium. While the name shares a common noun with a specific type of ecosystem, it serves as a distinct geographical location within the country.
In a general ecological context, a forest is defined by various factors including tree density, height, land use, and legal standing. The United Nations' Food and Agriculture Organization (FAO) specifically defines a forest as land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent. This definition excludes land that is predominantly under urban or agricultural use.
Globally, forests are significant features of the landscape. According to the Global Forest Resources Assessment 2025, forests covered approximately 4.14 billion hectares, representing about 31 percent of the world's land area in 2025.
