We studied the terrestrial micromammal (< 500 g) assemblages from Parque Nacional Lihué Calel (37°57’S, 65°33’W, La Pampa Province, Argentina) and surrounding areas using trapping data, field observations and analysis of owl pellets and felid and canid feces samples. The study area is included within the Pampean subdistrict of the Northern district of the Monte Desert. The landscape displays a mosaic of creosote bush of the genus Larrea, mixed shrub patches, grasslands and rocky outcrops. Field works were conducted during 2003-2008. Information about habitat, ecology, reproduction, and population structure is provided for the didelphid marsupials Lestodelphys halli and Thylamys pallidior, the cricetid rodents Akodon azarae, Akodon molinae, Calomys musculinus, Eligmodontia typus, Graomys griseoflavus, Oligoryzomys longicaudatus, and Reithrodon auritus, and the caviomorph rodents Ctenomys cf. C. azarae, Galea musteloides, Microcavia australis, and Tympanoctomys barrerae.
