“…Likewise, Leyva [ 27 ] and Morales [ 28 ] reported a pH < 4 and a high concentration of Al, Fe, Mn, Cu, Ni, and SO 4 2− in water, soil, and sediment in wetlands near Collotacocha lagoon and Uquián stream, highlighting the bioremediation capacity of wetland plant species. The main channel’s surface water is not suitable for human or animal consumption; furthermore, the metal concentration in waters representative of the sub-basin origin (LTara1, LTara2, QPuma, and QSNom3) decreases downstream due to the bioremediation of wetland flora, rainfall, and the precipitation of iron oxyhydroxysulfates [ 26 , 27 , 28 , 29 ].…”

The accelerated loss of glacial cover in the Cordillera Blanca in Áncash, Peru, exposes the underlying rocks with high concentrations of sulfides from the Chicama Formation to oxidation and leaching processes, generating acid rock drainage (ARD) in glacial and periglacial areas. These are transported by surface runoff, contaminating the surface water with high concentrations of metals and sulfates, as well as increasing the acidity, which poses a risk to human health and the ecosystem. Therefore, the risk indices for human health due to metal contamination were evaluated at 19 surface water sampling points distributed in the Río Negro sub-basin. Hydrochemical analyses revealed average metal concentrations in the following order: Fe (28.597 mg/L), Al (3.832 mg/L), Mn (1.085 mg/L), Zn (0.234 mg/L), Ni (0.085 mg/L), Co (0.053 mg/L), Li (0.036 mg/L), Cu (0.005 mg/L), and Pb (0.002 mg/L). The risk was determined by calculating the Heavy Metal Pollution Index (HPI) and the Hazard Index (HI). The average HPI value was 360.959, indicating a high level of contamination (HPI ≥ 150). The human health risk assessment indicated that adverse effects caused by iron, lithium, and cobalt in children and adults should be considered. Through the use of Pearson correlation analysis, principal component analysis, and cluster analysis, it was identified that SO42−, Fe, S, Al, Co, Mn, Ni, Zn, and Li originate from natural sources, associated with the generation of ARD in glacial and periglacial areas.

“…It covers an approximate area of 179.955 km 2 . The elevations range from 3300 to 5752 masl [ 29 ]. The district’s climate is characterized by two seasons: the flood season (from October to April) and the dry season (from May to September), with an average annual precipitation of 54.88 mm in 2022.…”

“…This research was in collaboration with the NPH and the Llama 2000 Asociación , a local community of farmers, who own the llamas . The farmers’ own village of Canrey Chico, Olleros has contaminated water due to acid rock drainage (ARD) that threatens their agriculture 53 . As an adaptation strategy to glacier retreat, the farmers aim to find solutions to increase the vegetation cover in recently deglacierized areas in order to reduce ARD.…”

Worldwide, mountain glaciers are shrinking rapidly. Consequently, large areas are becoming available for the development of novel alpine ecosystems. These harsh environments, however, delay primary succession. In this study with a local community, we conducted an inclusion experiment to investigate whether Llama glama influences soils and vegetation primary succession following glacial retreat. At the foot of the Uruashraju glacier in the Cordillera Blanca, Peru (~ 4680 m.a.s.l.), we established four llama inclusion plots and four control plots that we studied from 2019 to 2022, 24–40 years after deglacierization. After three years, the llama plots had significantly increased soil organic carbon and soil nitrogen. In the llama plots, we found a large, significant increase in vascular plant cover (+ 57%) between the second and third years of experimentation, and we identified four new species that were not present in 2019. Our results suggest that Llama glama, through their latrine behavior and role as a seed disperser, enhances the primary succession and novel ecosystem formation in recently deglacierized landscapes. Our study provides scientific support that rewilding of native Andean camelids may favor adaptation to glacier retreat and inform conservation and management strategies in proglacial landscapes.

The farmers' own village of Canrey Chico, Olleros has contaminated water due to natural acid rock drainage (ARD) that threatens their agriculture 72 . Previous oristic plot surveys carried on in the Uruashraju glacier foreland identi ed 47 vascular plant species (Zimmer et al, unpublished data; Table S1) We selected the Uruashraju foreland based on the Llama 2000 Asociación's shared interest in our research questions, the presence of llamas in the adjacent Quebrada, data availability for deglacierization chronology and oristic comparisons within the overall glacier foreland (Table S1), and the ecological representativeness of the site.…”

Worldwide, mountain glaciers are shrinking rapidly and projected to disappear largely by 2100. Consequently, large areas are becoming available for novel alpine ecosystems. These harsh environments, however, slow down primary succession. In this study with a local community, we conducted an inclusion experiment to investigate if and how Llama glama influences soils and vegetation primary succession following glacial retreat. At the foot of the Uruashraju glacier in the Cordillera Blanca, Peru (~ 4680 m.a.s.l.), we established four llama inclusion plots and four control plots that we studied from 2019 to 2022, 24–40 years after glacial retreat. After three years, the llama plots had significantly increased soil organic carbon and soil nitrogen. In the llama plots, we found a large, significant increase in vascular plant cover (+ 57%) between the second and third years of experimentation, and we identified four new species that were not present in 2019. Our results suggest that Llama glama, through their latrine behavior and role as a seed disperser, enhances the primary succession and novel ecosystem formation in recently deglaciated landscapes. Our study provides scientific support that rewilding of native Andean camelid may favor adaptation to glacier retreat and strengthen the conservation and management of novel proglacial ecosystems.
