Main Types of Natural Vegetation

Sri Lanka has four main types of natural vegetation:

  • Thorn Forest
  • Dry Zone Tropical Forest
  • Wet Zone Forest
  • Wet Zone Upper Hills Forest

Each type grows in different climate conditions and regions.

Thorn Forest (Dry Areas)

Thorn forests are found in the north-west and south-west coastal areas. These regions receive low rainfall.

Key Features:

  • Rainfall: About 635–1270 mm annually
  • Hot and dry climate
  • Plants have small leaves and thorns
  • Limited water availability

Trees here are usually short and spread out. Some inland areas also have stunted forests, where trees do not grow tall due to dry conditions.

Common Trees:

  • Burutha
  • Kaluwara (Ebony)
