Habitat and Ecology [top]

Habitat and Ecology:	This species lives in arid, steppe grassland punctuated at irregular intervals by wet meadows known as mallines (marshes) (Lacey and Wieczorek, 2003). The diets of some individuals in the C. haigi study population consisted primarily of Poa pratensis, diets of other individuals were dominated by the grass Stipa speciosa (E. A. Lacey and M. Manacorda; in litt. cited from Lacey and Wieczorek, 2003). Although its primary habitat is Patagonian Steppe it is also found in low Monte and Valdivian rain forest.
Systems:	Terrestrial
