The Playa Larga protected area was established in 1997. It is located east of the city of Ushuaia and includes a coastal strip that includes part of Playa Chica and all of Playa Larga. The sector corresponds to the southern slopes of the Sierras de Sorondo, with discontinuous slopes modeled by glacial action. Within the reserve there is an evergreen forest sector, where the dominant species is the Magellanic coihue (Nothofagus betuloides) associated with the canelo (Drymis winterii) and the notro (Embotrium coccinemum) and herbaceous vegetation near the coastline. Among the fauna, coastal and marine birds stand out. Sightings of the Andean condor (Vultur gryphus) are common in the area. According to the studies carried out, the portion of the coast between the mouth of the Olivia and Remolino rivers is the only preserved sector of Yamana occupation. Among the archaeological remains found in the region, the concheros, mounds formed by the accumulation of mollusk shells from their consumption, stand out. These are extremely fragile sites, exposed to destruction due to lack of knowledge and must be preserved.
