Primary forest interior, where the biological surveys are carried out

Before you can protect a place well, you have to know what is there.

Conservation begins with observation.

A forest can appear healthy from a distance while its ecological relationships are changing underneath the canopy. Research makes those changes visible: which species live here, where they are moving, how water changes between the headwaters and the river, where erosion is occurring, which habitats are regenerating, and which edges are under pressure.

The architecture beneath the forest

The beauty of Cerro Nara is inseparable from its geology. The country here is steep and structurally active, shaped by tectonic uplift, erosion, intense rainfall, and the constant movement of water downhill. Some slopes exceed 60 degrees. At El Salto del Nara, water drops more than 50 meters through the forest.

On terrain like this, trees perform structural work.

Roots bind the soil, leaf litter softens the force of rainfall, and understory growth slows water moving across the surface, while fallen branches, fungi, soil organisms and decaying matter keep building the porous ground beneath the canopy.

Protecting the forest here also protects the slopes.
