Monitoring Local Wildlife

Antamina ha realizado el monitoreo de flora y fauna en zonas de influencia directa (Quebrada Ayash y Quebrada Antamina)

Antamina has found is no record of activities in areas considered within the National Service of Natural Areas Protected by the State (SINANPE) or in the surrounding areas with elevated values of biodiversity. This means that no significant environmental impact on the biodiversity has been carried out.  However, as a component of the Environmental Monitoring Plan approved in our 2010 EIA, Antamina has carried out monitoring of bird life in the mine’s direct area of influence (Ayash Ravine and Antamina Ravine, and adjacent areas).

In addition, as part of the initiative with the Local Water Authority (ALA) in Huaraz, Antamina conducts two bird life monitoring counts every year at Conocha Lake. According to aquatic and terrestrial seasonal and spatial trends, it is not possible to identify any significant impact attributable to Antamina’s operation in its direct area of influence (Ayash Ravine and Antamina Ravine).  Similarly, the bird life monitoring counts at Conococha Lake do not identify any impact associated with the operation of the slurry pipeline or significant changes in the birdlife biodiversity pattern in this body of water. 

Furthermore, we conduct monitoring tests of Environmental Effects in communities of aquatic organisms in both coastal marine and inland water bodies adjacent to our operations. According to the results obtained to date, the trends associated with the abundance and diversity of benthonic macroinvertebrates as well as the health status of fish (trout, lornas and pintadillas, etc.) remain similar to the values recorded in the baseline studies, before Antamina started operations. 

Some variables such as the abundance of fish (e.g. trout) in the Ayash River and in Pampa Moruna have remained stable or even risen because the water system is monitored and ensures a water flow volume of at least 150 liters per second (lps) throughout the year.
