The area of the reserve was formerly part of Casa Grande hacienda which was closed in the past century due to the low prices of sugar and the Peruvian agrarian reform.

There are also more than 500 hectares of plantations of introduced species like: Grevillea robusta, Pinus radiata and Cupressus spp.

[1] The red deer was introduced for the first time in 1945 (3 individuals), but the locals killed them because they were afraid of how they looked like.

[4] Animals protected in this area include: the tapeti, the Andean fox, the vizcacha, the variable hawk, the American kestrel, the aplomado falcon, etc.

[1] Scientific research has also been carried out in the area, even before its designation as a game reserve: a cloud seeding program was performed in the 1950s and 1960s at the then hacienda and surrounding areas as part of a program to fight drought in the region.
