The Chilean State took a decisive step by formalizing the protection of ten salt flats and lagoons in the Atacama region. These areas, recognized as natural laboratories, safeguard forms of life that have adapted to extreme conditions.
The measure prioritizes the conservation of its biodiversity over the exploitation of mineral resources. The creation of six new protected areas increases the presence of safeguarded zones in the north of the country.
The decision is part of the National Lithium Strategy, which incorporates scientific criteria to value sensitive ecosystems. The selected salt flats integrate unique environments, many of them barely explored before these recent works.
This process also marks the creation of two Virgin Region Reserves, the strictest category of protection in the country. These are isolated territories where ecosystems remain practically without human intervention. The protection aims to ensure that this ecological heritage endures for future generations.
Exploring the puna: a journey to the extreme
Accessing these lagoons and salt flats means venturing into places where human presence is exceptional. Scientific expeditions had to face altitude, variable climate, and a territory that demands constant physical effort.
In return, they found pristine landscapes of a beauty little known outside the Altiplano. In areas like Laguna Escondida or the Salar de Eulogio, life concentrates in specific points where microhabitats still persist.
The observation of microorganisms, undescribed invertebrates, and high-Andean birds allowed updating the understanding of their ecological dynamics. Fossils and microbial formations reminiscent of the Earth’s primitive processes were also identified.
The record of these communities reveals a living system that unfolds between intense radiation, cold nights, and saline waters. Fossil stromatolites, algae, wetlands, and species adapted to aridity confirm their biological uniqueness. All this supports the urgency of protecting these environments before human pressure transforms them.
Science, State, and territory
The studies supporting this decision were developed between 2024 and 2025 with teams from various disciplines. The research updated hydrogeochemical, biological, and landscape information of each evaluated salt flat.
Interinstitutional work allowed defining protection standards aligned with the current environmental legislation. These new protected areas help compensate for the low proportion of safeguarded zones in northern Chile.
The region presents fragile ecosystems exposed to both climate change and productive activities. The expansion of conserved areas is a key step to balance development and environmental care.
Collaboration with local and indigenous communities also strengthened the process. This approach integrated ancestral knowledge and territorial perceptions fundamental for sustainable decisions. The protection of salt flats also seeks to recognize their cultural value and their role in the memory of the Andean landscape.
Essential information about the salt flats
Salt flats are closed basins where water evaporates and leaves salt deposits on the surface. They function as extreme ecosystems where microorganisms, algae, migratory birds, and specialized fauna persist.
Their physical-chemical characteristics allow studying processes similar to those of primitive Earth. The variability in salinity, pH, and radiation levels makes each salt flat a distinct environment.
Some have acidic waters, others concentrate mineral salts that determine unique colors and textures. These differences generate microhabitats that sustain uniquely adapted communities.
Besides their ecological value, salt flats have hydrogeological relevance. They act as reservoirs of groundwater and as indicators of the climatic behavior of the Altiplano. Their preservation allows continued research on how they respond to global and local changes.
The most well-known salt flats in the country
Among the protected salt flats are Gorbea, Pedernales, and Las Parinas, each with distinctive features. The Salar de Gorbea is recognized for its sulfur-stained lagoons and acidic pH waters, unique at a planetary level.
In Pedernales, microbial structures shaped by time compose a landscape evocative of primitive life. The Bravas and Escondida lagoons are characterized by their isolation and environmental purity.
In them, high-Andean birds, phosphorescent grasslands, and aquatic communities adapted to salinity are observed. These sectors safeguard ecological processes that can only be maintained under minimal human intervention conditions.
Other salt flats, like La Laguna or El Jilguero, complement the network by providing different types of wetlands and basins. Each contributes to representing the diversity of ecosystems in the Chilean Altiplano. Joint protection allows an integral approach to conserve this natural mosaic.
How ecotourism is experienced in the salt flats
The ecotourism in these environments is developed under strict guidelines that prioritize conservation. Visits are usually limited to enabled sectors, with guided tours and clear regulations to avoid impacts.
The experience focuses on the responsible observation of fauna, landscapes, and natural processes. The altitude and extreme climatic conditions add a component of controlled adventure.
Visitors usually prepare for abrupt temperature changes, intense radiation, and remote paths. This type of tourism promotes a deep connection with environments where nature completely dominates.
The model seeks to generate local benefits without compromising the integrity of the ecosystems. Small communities can offer services under low-impact guidelines. This balance turns ecotourism into an educational and preservation tool.
The benefits of this initiative
The protection of ten salt flats and lagoons significantly expands the conservation areas in northern Chile. The measure strengthens ecological resilience against climate change and protects unique and irreplaceable habitats.
It also ensures the continuity of fundamental scientific research to understand extreme ecosystems. The creation of protected areas contributes to more balanced territorial planning.
It allows harmonizing productive activity with environmental protection and the valuation of natural heritage. Additionally, it opens opportunities to promote controlled and sustainable ecotourism.
Finally, this advancement promotes a vision that recognizes salt flats as more than just mineral resources. It positions them as essential ecosystems for biodiversity and Andean cultural memory. Their conservation becomes an ethical commitment to future generations.
