Valle del Lunarejo (The Lunarejo Valley)

The Protected Lunarejo Valley Landscape is located in the extreme northwest of the department of Rivera, very close to Artigas and Salto and the border with Brazil. It is located in the northern part of the Cuchilla de Haedo system, which functions as a biological corridor for subtropical species of flora and fauna to enter Uruguayan territory from Brazil. It is an area representative of the Quebradas del Norte or the Cuesta Basáltica, a region that is notable for having a landscape of great beauty, with scenic features which are unique in the country, characterized by hills with flat tops which border narrow valleys shaped by the courses of the water known as "quebradas" (Gorges). The gorges are deep incisions notched into the basaltic rock, with steep slopes and reliefs, where caves, vertical surfaces and waterfalls converge and lush, subtropical jungle-type vegetation forms. The area possesses a great diversity of natural environments, including different types of grasslands, forests (hill, coastal, gorge), shrublands, rivers and creeks that provide shelter and food for many species of native fauna of great interest due to their rarity, distribution and abundance. In terms of birds, at least 150 species have been recorded, many of which can only be spotted here, including the sharp-tailed grass tyrant, the Buff-necked ibis, the Cliff flycatcher, the Seriema, the Blue-winged macaw and the Broad-winged hawk. Among the amphibians we can highlight two rare species: the Montevideo tree frog and the Rivera Redbelly Toad; among the reptiles the Crotalus durissus —extinct in the south of the country— and among the mammals the Anteater, the Greater naked-tailed armadillo, the Margay, the South American coati, the Brazilian porcupine and the Gray brocket.

  • A harmonious interaction between nature and cultureAbrir o Cerrar

    This landscape is the result of years of interaction between human activities –primarily for extensive grazing – and the natural environment; and this value is part of what we want to protect. In addition to the natural attributes, important historical and cultural values are added, closely linked to the characteristics of the territory. The relief of the area played a strategic role in the Uruguayan and Rio Grande do Sul revolutions. In particular, the area surrounding the town of Masoller was the scene of the battle which marked the end of civil wars in the country in 1904, in which General Aparicio Saravia was mortally wounded. Even today it is possible to see well preserved stone constructions which played a significant role in these conflicts.

  • Situation regarding the SNAP (National System of Protected Areas)Abrir o Cerrar

    The Protected Lunarejo Valley Landscape entered the National System of Protected Areas at the end of 2009. It includes 29,286 hectares which is the property of both private owners and the National Institute of Colonization, which has had departmental protection since 2001.
    Late in 2009 an agreement was signed between the Ministry of Housing, Spatial Planning and the Environment (MVOTMA) and the Municipality of Rivera to coordinate the first management actions in the area, including the development of an administration plan.
