The mara is native to the dry grasslands and thorn scrub of Patagonia in Argentina and Chile, as well as parts of Paraguay.

The mara primarily feeds on grasses, herbs, and shrubs. It forms lifelong pair bonds, only seeking a new mate if its partner dies. Typically, it has one to three offspring per year, all of which are born in communal dens that provide maximum protection.

The mara faces threats from the European hare, which was introduced to Patagonia by humans, and from other grazing herbivores such as sheep. Although it remains relatively widespread in its native range, population numbers are declining due to habitat loss.

The mara can be quite social when raised with human interaction but may shift to nocturnal habits to avoid contact. Its young are well-developed at birth and can begin grazing within a day.

At Fota Wildlife Park, the mara roams freely, often found near the African Savannah and in adjacent woodland areas. It has been a favourite of visitors since its arrival in the 1990s. While visitors can get close to observe it, the mara tends to avoid direct contact. The species has bred successfully at Fota, contributing to the conservation of this unique rodent.
