The Tocantins/Pindare moist forests cover the eastern Amazon in northern Brazil, spanning the east of Para and the north of Maranhao, south of the Amazon River's mouth and framed by the Tocantins, Mearim, and Pindare rivers across a low alluvial plain. Vegetation divides into terra firme upland rainforest and flooded igapo and varzea forests, with characteristic trees including the Brazil nut, mahogany (Swietenia macrophylla), the acai palm (Euterpe oleraceae), the Mauritia palm, and Symphonia globulifera. The climate is equatorial monsoonal, averaging around 26 to 27.5 degrees Celsius, with annual rainfall rising from roughly 1,500 mm in the drier south to 2,500 mm in the north and a pronounced dry season of about five months. Despite supporting hundreds of bird and mammal species and the endemic, endangered green-thighed parrot as its flagship, this is among the most developed and severely degraded parts of the Amazon, with over a third of its original forest already cleared. For warm, humid gardens, native ornamentals here include the graceful acai and Mauritia fan palms.

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.
