Asian grassland (6)

I believe the answer is:

steppe

(Other definitions for steppe that I've seen before include "Large treeless area of Siberia" , "Dry plain of Eurasia" , "Dry grassy plain of central Europe" , "Dry grassy plain of eastern Europe and Asia" , "Flat area of eastern Europe or Russia" .)

I've seen this clue in the Sydney Morning Herald.
