In 1972, Costa Rican conservationists established the Monteverde Cloud Forest Reserve. 54 years later, it protects 10,500 hectares of cloud forest feeding two oceans

High in Costa Rica, where warm, moist air meets cooler mountain temperatures, the Monteverde Cloud Forest Reserve has become one of the country’s most remarkable natural areas. The cloud forest is known for its extraordinary biodiversity, its mist-covered landscape and its position along the Continental Divide of the Americas, as per a report by The BBC Wildlife.

It is also a place where water can arrive through the air, with mist contributing significantly to the forest’s water supply.

What makes Monteverde so unusual?

Monteverde stretches across more than 10,000 acres of cloud forest, or more than 4,000 hectares in the figures provided. The reserve was officially formed in the 1970s and has since fascinated both researchers and visitors.

Its forests contain more than 2,500 plant species, 400 bird species, 100 mammal species and 120 reptilian and amphibian species, along with thousands of insects.

More than 750 tree species have also been recorded, while the reserve contains more than 450 orchid species, described as the highest concentration known on Earth.

The forest sits between roughly 3,900 and 8,200 feet above sea level. Warm, moisture-filled air encounters the cooler mountain environment, creating the misty conditions that define a cloud forest.

How does the forest collect water from mist?

One of Monteverde’s most unusual features is what is known as horizontal precipitation. Mist can provide up to 40% of the total water captured by the forest. Plants collect moisture directly from the mist, meaning the forest can receive water even when rain is not reaching the ground.

The reserve also sits along the Continental Divide of the Americas. This divide separates watersheds flowing toward the Pacific from river systems draining toward the Atlantic and Arctic oceans.

Moisture from the Caribbean meets Pacific winds in the area, creating a rare combination of climatic conditions.

That helps explain why such a remarkable variety of plants and animals can exist in the same forest.

Which animals live in Monteverde?

The reserve provides habitat for an extraordinary range of wildlife.

Resplendent quetzals are among its best-known birds. They live in the misty canopy and make their nests by hollowing out rotten trees or stumps. Their diet includes fruit, insects, lizards and other small creatures.

The bird was sacred to ancient Maya and Aztec peoples, although its population is now declining because of habitat loss.

Monteverde is also home to Baird’s tapirs, the largest native land mammals in Central America, along with ocelots, white-faced capuchins, two-toed sloths and greater false vampire bats.

The jaguar is another resident. It is the largest cat in the Americas.

But the forest’s biodiversity story also includes species that have disappeared.

The golden toad, once endemic to a small area within the reserve, was declared extinct in 2004 after its population collapsed in 1989. Climate change has been suggested as a key factor, although researchers have also pointed to chytrid fungus and habitat loss working alongside climate change.

The Chiriquí harlequin frog faced a similar fate. Biologists who observed the frogs in the wild described them as ‘waving’ at one another, possibly as a way of avoiding fights or as part of mating behavior. The species was last seen in 1996 and was declared extinct in 2019.

Today, Monteverde remains a striking example of how much life can exist within a cloud forest, and how closely that life depends on the unusual relationship between mountains, moisture and climate.

FAQs
