The Beni savanna, also mapped as the Llanos de Moxos, is a tropical lowland savanna that lies in the southwestern Amazon basin, almost entirely within northern Bolivia's Beni Department, with small extensions into Brazil along the Iténez River and into Peru's Pampas del Heath. It forms a mosaic of seasonally flooded grassland and wetland threaded with forest islands and riverside gallery forest, where sedges and grasses give way to trumpet trees (Tabebuia ochracea), grugru palm, and stands of Attalea and Acrocomia palms in better-drained ground. The climate is tropical with a pronounced wet season from roughly December to May, when rains and snowmelt from the nearby Andes flood up to half the low-lying terrain for months at a time. It is one of South America's largest savanna complexes and the flagship home of the critically endangered, endemic blue-throated macaw (Ara glaucogularis), alongside hundreds of recorded bird species, though cattle grazing and seasonal burning press on its habitats. For gardeners, the showy native trumpet trees of the genus Tabebuia are familiar flowering ornamentals well suited to warm, seasonally wet climates.

About the tropical & subtropical grasslands, savannas & shrublands biome
Warm grasslands and savannas where grasses dominate and trees are scattered, maintained by seasonal rainfall, grazing, and fire. They support large herbivore communities and respond sharply to wet–dry cycles.
Catalog plants suited to this ecoregion
Computed from each plant's stated USDA zone range against this ecoregion's CHELSA-derived current zone range, with the CHELSA mid-century warming delta applied for the projection. Plants whose stated range falls outside both the current and projected zone end up dropped; the rest land in one of the three buckets below.
Climate-resilient picks · 79
These plants fit this ecoregion today AND remain in range under the mid-century SSP3-7.0 projection. Lead with these for a planting that holds up as the climate shifts.
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.
