Natural Vegetation
Plant life that grows naturally in an area without human intervention, heavily dependent on temperature, rainfall, and soil conditions.
Tropical Evergreen Forests
Dense forests found in regions receiving more than 200 cm of annual rainfall, characterized by tall trees that do not shed their leaves all at once.
Tropical Deciduous Forests
Also known as monsoon forests, these shed their leaves during the dry season to conserve water and grow in areas with 70 cm to 200 cm of rainfall.
Montane Forests
Vegetation found in mountainous regions where temperature decreases with altitude, leading to a zonal arrangement of trees from tropical to alpine types.
Biosphere Reserve
A protected area meant for preserving biodiversity, promoting sustainable development, and conducting scientific research and education.
