Abstract for S01


Tropical Grassland, Savanna & Shrubland [does not occur in Canada]
Prairies, savanes et arbustaies tropicales [absentes du Canada]


Tropical Grassland, Savanna & Shrubland is dominated by grasses and shrubs, with or without scattered trees. Some occur in climates too dry for forest; others depend on soil conditions or fire, or both, rather than climate. The structure is a single, major grass or shrub stratum, or a mix of the two, with trees typically less than 10% cover, rarely with bare ground.
