The sector of use of puna or paramo, presents a humid and frigid climate with poor vegetation that serves as grazing for sheep and cattle. This area is located mainly in the entire extension of the Matara hamlet and upper parts of the Quebradas Pacchac and Chorrillos basins.

Vegetation The flora is largely dominated by Eucalyptus trees and the Swiss pine (Pinus cembra). They share the habitat with native Andean vegetation, such as quenual, tara, quishuar, molle, ichu, and an abundant number of aromatic plants such as cedar and muña.

Wildlife Among the mammals, tarucas, deer, llamas, spectacled bears and foxes stand out in the thickest areas of the puna forests. Rodents such as vizcacha and muca are common in stony areas.

History

Presence in ancient Peru and the Inca Empire The archaeological site of Kajur is one of the oldest human settlements in this part of the Cordillera Negra. The archaeological site of Cuchicoto located near the summit of Canchón shows the influence of Recuay culture during the Early Intermediate period.

The priest Augusto Soriano Infante collected in 1953 a myth about the pre-Inca foundation of Pampas Grande:Folklore, Vol. III No 31, Lima, septiembre, 1953 p.1021 After a bloody and long campaign of resistance against the expanding Inca Empire led by Huayna Cápac, the Lordship of Huaylas surrendered to the Inca Empire at a high cost. The most important temple of the Huaylas, Pumacayán, was destroyed, and as a vassal, all the curacas of the mentioned ethnic groups were forced to send their daughters with the Inca to join it as secondary wives.Orsini, Carolina (2015). Arqueología de Chacas. Comunidades, asentamientos y paisaje en un valle de los Andes Centrales del Perú. Italia, Edizioni Pendragon.

Following the population order of the Incas, the huaylas were subdivided into two parts: Hanan Huaylas and Hurin Huaylas, territories that included the current provinces of Huaylas, Yungay and Carhuaz in Hanan Huaylas, and the provinces of Huaraz, Recuay and Aija in Hurin Huaylas, Pampas would become part of this subdivision under the Inca administrative center of Recuay Viejo.

Colonial time period The inhabitants of the Huaylas ethnic group surrendered without resistance to the Spanish conquerors in order to get rid of the Incas. A few years later, the conquerors began with the distribution of these lands and the founding of plantations and sugar mills to take advantage of native labor.

After the Spanish conquest, the Pampas territory belonged to the encomienda de Recuay, which also included the towns of Recuay and Aija.

This encomienda was owned by the conquerors Jerónimo de Aliaga and Sebastián de Torres until the year 1537, remaining in the hands of Jerónimo de Aliaga until his return to Spain in 1550. After that year, the Recuay Encomienda entered into dispute, remaining in the hands of Juan de Aliaga until 1570, when the Encomienda de Recuay was united with that of Huaraz, being designated encomendero Don Hernando de Torres.

In 1605 in the part that is today Pampas Grande the huaranga of Ichocpoma belonging to the saya of Lurin-Huaylla was located.Información de Ampuero / Yupanqui, 1557: 282 In 1651, in the Huaylas huaranga the doctrine of La Asunción de Huaylas was founded, with two partialities: Allauca and Ichoc.AAL. Padrón de Atunhuaylas 1774. Here was the town of Pampas, with the ayllu Poma, west of Cajamarquilla.Padrón de Pampas. AAL- 1774.

Foundation The foundation of the town was carried out during the government of the viceroy Francisco de Toledo, promoter of the reductions of Indians, that is, populations of natives with their main square, church, town hall and their own plots. Until then the native population lived dispersed in the territory and this measure facilitated the work of the priests and the authorities in general. It was the norm to establish the cities of the colonized territories by imposing the name of a saint under whose protection and devotion the foundation was made. The reduction was named "San Jerónimo de Pampas", possibly on September 30, the saint's holiday.

There is a tradition, according to which the first foreigners who set foot on Pampas land were the Portuguese, who came from Huánuco in search of mines, accompanied by Huanuqueño Indian miners, since in Huánuco there was a company of bell melters called María Angola.

Years later, the Spaniards arrived wanting to found a town in what is now La Victoria, making a foundation for the chapel, from which it says the effigy of San Jerónimo had escaped. After several days of searching, they found the Patron Saint in the current site where the main church of Pampas Grande is, at that time the area where the church is, was not an appropriate site for an urbanization, they were chacras with platforms, full of ankicashan 6. Due to the difficulties the Spanish had moved to Cañipampa where they also formed a chapel, again the effigy of San Jerónimo escaped, being again in the same place, where there was a huge rock, whose edges were surrounded by pucakantu bushes, true bush with red flowers.
