Forest biomes are dominated by trees but seasonality and rainfall can vary dramatically.
Deciduous forest
Forest dominated by deciduous trees that shed their leaves during one season of the year. Often associated with temperate locations but tropical forests also exist.
Rainforest
Can be temperate or tropical, all dominated by trees forming a closed canopy meaning little sunlight reaches the forest floor. Typically lots of rain but dependent on season.
Scrub forest
These forests develop in locations where a dry season occurs. As a result of this, most trees are stunted and shrub-like. Most other vegetation is also smaller than elsewhere on the globe.
