Solimões-Japurá moist forests
RESOLVE 503
The Solimões-Japurá moist forests stretch across western Amazonia in northwestern Brazil, southeastern Colombia, and eastern Peru, bounded on the north by the Caquetá River, which becomes the Japurá in Brazil, and running east to where the Japurá and Solimões rivers meet. The terrain is upland alluvial plain, mostly between 100 and 220 meters in elevation, cloaked in tall, dense evergreen rainforest rich in families such as Annonaceae, Lecythidaceae, Myristicaceae, Fabaceae, and Sapotaceae, with emergent giants like kapok (Ceiba pentandra), Terminalia amazonia, and Cedrelinga cateniformis rising above palms, lianas, and epiphytes. The climate is hot and humid year-round, Köppen Af, with mean temperatures around 24 to 26°C and roughly 3,000 millimeters of annual rainfall on nutrient-poor oxisols and ultisols. The ecoregion ranks among the most biodiverse places on Earth, holding about 181 mammal species (jaguars, tapirs, and giant otters among them) and some 542 bird species, and it remains relatively intact, safeguarded in part by protected areas such as Amacayacu National Park and the Mamirauá Sustainable Development Reserve. Gardeners may recognize native trees of horticultural note here, including the buttressed kapok and tropical cedar (Cedrela odorata).
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.
