Biome: TROPICAL HUMID FOREST
Biome Overview:
The quintessential warm and wet evergreen forests. They usually have a tall closed canopy, with large girth trees that have buttressed roots. The forest has a fairly open understory except in light gaps where the ground cover an lower canopy becomes extremely thick. They generally exist in areas that do not receive frost and have over 1200mm of rainfall per year. There can be a short dry season but periods of when plat stress occurs is generally less than three months, and in the cooler months. In drier areas they merge into Seasonal Forests, in cooler areas they merge into Temperate Deciduous Forests, and in fire-prone areas, they merge with Savannas or Sclerophyll Forests.
Sub-Biomes:
Lowland Rainforest: Wet, evergreen tall forest with thick full canopy cover and open undergrowth.
Example: Neotropical Lowland Rainforest (Amazon Basin)
Semi-Evergreen Forest: Generally humid forests with near-complete canopy cover in which a minority of the trees lose their leaves.
Example: Indo-Malayan Semi-Evergreen Forest
Montane/Subtropical Evergreen Forest: Warm, wet forests with almost closed canopy
of evergreen or partially deciduous trees.
