 A rainforest is a forested biome with high annual rainfall. Tropical rainforests arise due to the Intertropical Convergence Zone, but temperate rainforests also exist. As well as prodigious rainfall, many rainforests are characterized by a high number of resident species and tremendous biodiversity. Botanical gardens grow a wide variety of plants primarily categorized and documented for scientific purposes, but also for the enjoyment and education of visitors, a consideration that has become essential to secure public funding.
