Most of Costa Rica’s forests can be primarily classified into three groups; rainforests, cloud forests and topical dry forests. And while rainforests are the most common habitat, the cloud forests of Costa Rica are a magnificent sight to behold. Rainforests can be found in the southwest of the country as well as in the Atlantic lowlands, with towering trees and looping vines that create a magical wispy environment. Receiving a high annual rainfall, these dense forests are characterized by a wealth of plant and animal life. Rainforests are located at lower elevations, and as a result, they tend to be much warmer, especially during the dry season. Cloud forests, on the other hand, are usually located at much higher elevations, and are much cooler. This difference in temperature contributes to the mist and fog that is often visible in cloud forests, as the milder temperatures slow the evaporation process. However, despite being a little cooler than rainforests, cloud forests are very humid. Cloud forests generate water by capturing water from fog (surface clouds). Water condenses on the leaves and branches of cloud forest trees, epiphytes and lichen, drips to the forest floor, and enters streams. The tropical evergreen cloud forests on the slopes of the Cordillera de Talamanca in Costa Rica’s southern highlands is of vital importance both as a source of drinking and irrigation water to the main cities in the Valle Central and as a bastion of many endemic species. This is not meant to be a comprehensive survey of the plants in the cloud forest, concentrating instead on important and noteworthy plants in this ecosystem.
Situated among the mist-covered peaks of the Talamanca Mountains, Los Quetzales National Park was established in 2006. This park lies 47 miles southeast of San Jose, and you can easily reach this park from Manuel Antonio on the Pacific Ocean. From Jacó it’s about a two-hour trip. The entrance to the park is on Cerro de la Muerte, just before the turnoff for San Gerardo de Dota. Most of the park area is around the both side of the Savegre river that emerges in the Cerro de la Muerte and connects to the Pacific Ocean close to the Manuel Antonio National Park. it is surrounded by natural rainforest, breathtaking waterfalls, and beautiful canyons. This park includes not only rainforests but also cloud forests, formed by the collision of warm, moist Caribbean trade wind with the Talamanca mountain range which stretches from southwest of San José to beyond the border with Panama. When tiny droplets are deposited on surfaces before they collect together and fall as rain it’s called horizontal precipitation and in cloud forests it can be the main source of moisture. Peaks enveloped by trade wind-derived clouds can capture huge amounts of water when they are covered with tropical montane cloud forests. Their sponge-like epiphytes (mosses, ferns and bromeliads) massively increase the surface area for horizontal precipitation. Vibrantly colored, from the miniature to the gigantic, Los Quetzales flora is some of the most beautiful in the world. There seemingly endless tropical flower species and even orchids. Many can be found growing wild on the trunks of giant trees.
When I was in Costa Rica for a bird photography tour recently with Tropical Birding, I had an opportunity to visit Frog’s Heaven, a place that specializes in catching wild frogs for photography. The frogs are subsequently released back into the environment. These tiny frogs are getting harder to find, even in the optimized environments of the Frog’s Heaven preserve. Research suggests that even though amphibians are severely declining worldwide, there is no simple solution to halting or reversing these declines. Amphibians are good indicators of significant environmental changes. Amphibians, unlike people, breathe at least partly through their skin, which is constantly exposed to everything in their environment. Consequently, their bodies are much more sensitive to environmental factors such as disease, pollution, toxic chemicals, ultraviolet radiation, and habitat destruction. The worldwide occurrences of amphibian declines and deformities could be an early warning that some of our ecosystems, even seemingly pristine ones, are seriously out of balance. We were able to photograph a nice cross section of the different types of frogs which I thought I would present here.
