The Eastern Java-Bali rain forests cover the lowland moist forests of the eastern half of Java and the island of Bali in Indonesia, extending to smaller offshore islands such as Madura and the Kangean Islands. These are predominantly moist deciduous and semi-evergreen forests growing on volcanic and alluvial soils, with characteristic lowland trees including Homalium tomentosum, Albizia lebbekoides, Acacia species, Cassia fistula, Artocarpus elasticus, and Dysoxylum caulostachyum. The climate is a tropical monsoon regime with every month averaging above 18 degrees Celsius, annual rainfall ranging from roughly 1,500 to 4,000 millimeters, and a pronounced four-to-six-month dry season that lengthens toward the drier north coast. The ecoregion supports over 350 bird species and around 103 mammals, including roughly 15 ecologically important fruit bats that aid pollination, and its flagship species is the critically endangered, endemic Bali myna (Leucopsar rothschildi); less than three percent of the region is formally protected. For gardeners, several native genera here, such as Cassia and Albizia, are widely grown as flowering ornamental trees.

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.
