The loss of preferential habitats could have caused the occupation of forest formations less preferred by the species. This would explain the recent records in the east of Parana and Santa Catarina (Montane Forest and Submontane Ombrophilous Dense Forest) (Margarido and Braga 2004, J.M.B. Duarte pers. comm.) and the absence of historical records in these regions (Rossi 2000).
The National Museum of Natural History of Paraguay has records of M. nana in San Rafael National Park region (Gamarra de Fox and Martin 1996) and in Argentina, the species may be found in almost all the remaining natural forests of Misiones Province (D.M. Varella pers. comm.).

In Paraguay, the populations are also threatened due to loss of habitat (J.L.Cartes pers. comm.)
In Argentina, M. nana is considered as vulnerable although the populations of Misiones Province seem to be stable (Diaz and Ojeda 2000). One of the major conservation problems is hunting, mainly in the provincial parks and private forests. However, the construction of roads has increased the number of road-kills and could be affecting the populations.
In Misiones, Argentina, many conservation units shelter important populations of this species, such as the Iguaçu National Park and the State Parks of Urugua-í, Foerster, Piñalito, Cruce Caballero, Esmeralda, Moconá y Cuña Pirú (D.M. Varela pers. comm.). In Paraguay, the majority of the Atlantic Forest habitats are extinct, what remains is in protected areas such as Reserva Natural del Bosque Mbaracayú and the Itaipu Hydroelectric Power Plant Reserve. Currently, San Rafael National Park, which has records of the species, suffers many pressures and threats (J.L. Cartes pers. comm.)
The Pygmy Brocket, Mazama nana, is a brocket deer species from South America. It is found in Argentina, southern Brazil and Paraguay. It is a small deer with short legs, weighing 15 to 20 kilograms (33 to 44 lb). It is reddish-brown in color.
This species is sometimes considered a subspecies of Mazama rufina.
