North America - Woodland Savanna

Woodland and savanna systems are not as dominant in the landscape as the shrubland and grassland biomes of North America, but they are spread patchily throughout the land west of the Rocky Mountains. Three ecotypes exist within the woodland-savanna biome of North America including oak woodlands, pinyon-juniper woodlands and Ponderosa pine savanna. Fire has historically constrained these systems to foothills, ridgelines and elevations generally above the basins and plains filled with shrubs and grasses.
