The Cardamom Mountains rain forests cover the wet evergreen highlands of the Cardamom and Elephant mountains in southwestern Cambodia and southeastern Thailand, extending to Vietnam's Phu Quoc island along the Gulf of Thailand. Forests here grade from lowland and hill evergreen stands into montane forest, where the beech family (Fagaceae) genera Lithocarpus and Castanopsis dominate alongside Lauraceae trees such as Cinnamomum and Litsea, with myrtle-family Syzygium and abundant epiphytic orchids. Rising steeply to over 1,500 meters, the range intercepts moisture-laden monsoon winds and receives very high annual rainfall, exceeding 5,000 millimeters in some valleys. Part of the globally important Indo-Burma biodiversity hotspot, it is one of Southeast Asia's most species-rich and endemic-rich forests, sheltering Asian elephants, tigers, clouded leopards, endemic chestnut-headed and Siamese partridges, and the critically endangered Siamese crocodile, with much of the range now within Southern Cardamom National Park. For gardeners, native genera such as the aromatic Cinnamomum and the ornamental Syzygium illustrate the region's warm, perpetually humid, frost-free climate.

About the tropical & subtropical moist broadleaf forests biome
Warm, wet, highly productive forests — including tropical rainforests — with closed canopies, near year-round growing seasons, and the richest terrestrial biodiversity on Earth. Low seasonality and high rainfall sustain dense, layered vegetation from canopy to forest floor.
Catalog plants suited to this ecoregion
No catalog plants intersect this ecoregion's zone range. As the catalog grows to cover this region's climate band, suggestions will surface here.
Collections for this ecoregion
No curated collection's plants all fit this ecoregion's zone range. We surface a collection only when every member would grow here — partial fits get filtered out rather than mislead. As the catalog and the curated set both grow, this section will fill in.
