Two Types of Tropical Forest: Rainforest vs. Dry Forest

Fundamental Climate-Driven Distinction

FeatureTropical RainforestTropical Dry Forest
Annual Rainfall>2,000 mm (often 2,500–4,000+)1,000–1,500 mm (highly seasonal)
Dry SeasonNone or <1–2 months4–6+ months (distinct)
TemperatureStable 25–28°C year-round25–30°C; wider diurnal range
CanopyClosed, multi-layered, 30–45 mOpen, 15–25 m; deciduous in dry season
BiodiversityHighest on Earth (50%+ species)High but lower; many endemics
SoilOxisols/Ultisols; nutrient-poor, rapid cyclingAlfisols/Vertisols; more fertile, seasonal nutrients
Key RegionsAmazon, Congo, SE Asia (Borneo, New Guinea)Caatinga (Brazil), Chiquitano (Bolivia), N. Australia, Madagascar, Pacific coast Mesoamerica
ThreatsDeforestation (cattle, soy, palm oil)Conversion to agriculture/pasture; fire

Why It Matters

Dry forests are more endangered proportionally—easier to clear, better soils, less protected. Both are carbon reservoirs, climate regulators, and indigenous homelands.
