Why
we restore
The Sierras Grandes are a great reservoir that stores and provides the water for more than 3 million people in the provinces of Córdoba and San Luis. However, centuries of logging, fires and overgrazing wiped out 97% of the native forest and grassland. This created a vicious cycle of soil loss, biodiversity loss, exodus of local communities, long droughts and severe floods.

01 · Memory of the landscape
The gradual change of the landscape

The sierras used to be forest. Extensive ranching and fire reduced their original cover until the arid landscape seemed to be the natural state of the mountains.
Out of all this our purpose is born:
To cover the mountains with forests again.
To recover the landscape.
More forests · More water · More life
02 · Water impact
More forests, more water

A single hectare of mature forest captures up to 1.6 million liters of water per year. Scientific evidence shows that reforested high-altitude basins can increase their flow by 30%. Every tree that returns to the mountain translates into tangible reserves of pure fresh water, securing the supply of rivers, regional production, and the towns and cities that depend on the reservoirs.

03 · Soil & carbon
Stop desertification,
capture carbon

The lack of vegetation cover left the sierras exposed. The soil loses moisture, erodes and progressively turns into rock. By reforesting, we stop desertification and recover the structure of fertile soil. At the same time, a mature Polylepis ecosystem can capture up to 48 tons of carbon per hectare, turning our mountains into active protection against the climate crisis.

04 · Human impact
A growing network

Working in the mountains has a direct impact on people. We foster commitment and create local jobs in the communities. We understand regeneration as a process that transforms us internally. Today we are a growing network of thousands of people involved in ecology, working coherently and acting on the territory to bring our ecosystem back to life.
