The low relief of the savannas, coupled with wet season rains and snowmelt from the Andes, cause up to half the land to flood seasonally. The Llanos de Moxos is surrounded by tropical moist forests; the Southwestern Amazonian moist forests to the north, west, and south, and the Madeira-Tapajós moist forests to the east.

[1] Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions.

Map of oak savanna distribution in North America. Although there are pockets of oak savanna almost anywhere in North America where oaks are present, there are three major oak savanna areas: 1) California, British Columbia, Washington and Oregon in the west; 2) Southwestern United States and northern Mexico; and 3) the prairie/forest border zone of the Midwestern United States.
