Guandera Biological Station: Introduction

Thu, 23 Apr 2026 00:00:00 GMT

Walk uphill through the forest at Guandera and something strange happens. There is no transition. One moment you are under a canopy of twisted, aerial-rooted trees, surrounded by moss and the call of the grey-breasted mountain toucan. The next moment you step out of the forest and into grassland - wide open, cold, colonized by squat plants that look like robed monks. The boundary is sharp, almost surgical, as if someone drew it with a ruler. Most Andean mountains grade slowly from forest into alpine through bands of dwarf trees and shrubs. Guandera does not. French soil scientists who came to solve this puzzle found the answer in the dirt: the forest soils and the paramo soils are fundamentally different, and they have been sitting beside each other for thousands of years. The magic line is real. It has always been real.

Guandera Biological Station: The Forest That Almost Wasn't

Thu, 23 Apr 2026 00:00:00 GMT

Guandera Biological Station was established in 1994, and it very nearly wasn't. The forest it protects is a remnant - the last substantial piece of inter-Andean valley montane forest that once carpeted the upper slopes of wetter valleys from Colombia to Peru. Everywhere else, it ...

Guandera Biological Station: Trees That Behave Like Banyans

Thu, 23 Apr 2026 00:00:00 GMT

The station takes its name from the guandera tree - *Clusia* species - that dominates large groves here. Clusias drop aerial roots from their branches, the roots push down into the soil, new trunks form around the parent, and over decades a single tree becomes a maze of interconn...

Guandera Biological Station: The Paramo Without Frailejones - Almost

Thu, 23 Apr 2026 00:00:00 GMT

Above the forest sits one of Ecuador's most remote paramos. Most Andean alpine grasslands are heavily modified by pastoralism - indigenous communities live in or near them, grazing alpacas and llamas, burning the grass periodically to stimulate regrowth. Guandera's paramo is diff...

Guandera Biological Station: A Last Haven

Thu, 23 Apr 2026 00:00:00 GMT

Guandera holds what fragments of northern Ecuador's megafauna still survive. Spectacled bears - *Tremarctos ornatus*, South America's only native bear, listed as vulnerable - forage for bromeliad hearts and bamboo shoots in the forest understory. Andean fox, mountain lion, and th...

Guandera Biological Station: El Angel and the Pattern

Thu, 23 Apr 2026 00:00:00 GMT

Across the valley from Guandera, on the Western Cordillera, sits El Angel National Park - a government-managed protected area that covers an extensive paramo grassland and complements Guandera's forest protection. The Jatun Sacha Foundation, which manages Guandera, works closely ...
