A recently published study reveals that vicuña dung has a surprising ecological impact. It can transform high mountain arid soils into oases of life, accelerating plant regeneration by more than 100 years.
In the Andes, these camelids use community latrines, where they deposit large amounts of dung. These nutrient concentrations promote plant colonization in areas newly exposed by glacier melting, reducing decades of natural waiting to just a few years.
Vicuña dung as a natural fertilizer, what does the study say
The study, conducted by University of Colorado, United States, determined that the vicuñas’ behavior vitamins imply a profound landscape transformation:
-
They enrich the soil with organic matter, phosphorus, and nitrogen, concentrated in small plots.
-
They increase moisture retention even in extremely dry conditions.
-
They stimulate plant germination, growth, and local microbial diversity, facilitating the creation of primary ecosystems.
The areas around these latrines act as micro-oases that attract local fauna. New plants in these patches generate more complex ecosystems: herbivores follow the plant growth and predators like pumas approach these areas, showing a dynamic expansion of life at extreme altitudes.
Keys for conservation and inspired strategies
Although this phenomenon shows great natural potential, climate change imposes limitations: the glacial retreat speed exceeds natural adaptive capacity.
Between 2000 and 2019, approximately 267,000 billion tons of ice per year were lost, and it is projected that up to 68% of glaciers may disappear in the coming decades.
Therefore, researchers suggest integrating this natural process into effective ecological restoration strategies, including:
-
Legal protection of key areas where vicuñas act as natural regenerators.
-
Scientific monitoring to assess their impact on plant succession and associated fauna.
-
Restoration projects that mimic the use of dung and local organic matter in degraded areas.
-
Education and participation of local communities to preserve this ancestral ecological function.
What vicuñas are like
The vicuña (Vicugna vicugna) is a wild animal that inhabits the high mountains of the Andes, mainly in countries like Peru, Bolivia, Argentina, Chile, and Ecuador. They live between 3,200 and 4,800 meters above sea level, in cold, dry areas with little vegetation.
They play a key ecological role in the high Andean ecosystems. Additionally, for many Andean communities, the vicuña has deep symbolic and economic significance. Since pre-Inca times, their wool was considered a luxury reserved for the nobility. Today, their sustainable management is a source of income for indigenous and rural communities.
