Children’s Eternal Rainforest Private Reserve Costa Rica is the largest private reserve in Costa Rica, that protects the country’s tropical rainforest, primary forest, secondary forest and regeneration areas in northwestern Costa Rica, a project that has been part of the dream of children’s and adults around the world. On September 18th, 2007, it was declared part of the Peace and Water Biosphere Reserve by UNESCO, and is administered by the Monteverde Conservation League
(ACM in Spanish).
The Children’s Eternal Rainforest is located in the Tilaran Mountain Range, bordering the Arenal Volcano National Park, the higher elevations of Monteverde and Miramar, reaching the Alberto Manuel Brenes Reserve in San Ramon. It continues through the San Carlos zone, close to the populations of San Jorge, La Tiga, San Isidro de Peñas Blancas, Chachagua, and El Castillo.
The Children’s Eternal Rainforest exists thanks to the dream of saving the rainforest by children. It’s fundraising campaign began in 1987, in a small rural school in Sweden, while studying tropical forests prompted a nine-year-old Roland Teinsuu, to ask what they could do to keep the rainforest and the animals that live in it safe from destruction. Young Roland’s question led his teammates to make a campaign to raise money for the purchase and protection of threatened rainforest in Costa Rica. With the guiding hand of teacher Eha Kern and her husband Bernd, and the assistance of tropical biologist Sharon Kinsman, who introduced the Monteverde project to the school, Roland and his classmates raised enough money to buy six hectares of rainforest at a cost of $250 per hectare, including surveying, title search, and legal fees connected with the purchase.
Linked to this initial success, this group of children dedicated to saving the tropical forests formed the “Barnens Regnskog” (Children’s Rainforest). The vision took hold, sweeping the globe, with contributions flocking in from the far corners of the world. Fundraising projects have been as varied as a child’s imagination. Children have collected aluminum cans and glass, baked cookies for sale with rainforest ingredients (ginger, chocolate, vanilla), or asked for a parcel of rainforest as a Christmas or birthday gift.
The original six-hectare preserve, settled near Monteverde in 1988, has grown to more than 22,500 hectares (over 54,000 acres) of land, currently is the largest private reserve in Costa Rica, and to date, 44 different countries have contributed to the acquisition and protection of the territories of the Children’s Eternal Rainforest.
In the Children’s Eternal Rainforest are represented 6 out of the 12 life zones present in Costa Rica, as well as a variety of habitats and ecosystems that span from 450 to 1800 meters above sea level, so it presents a topography characterized by peaks and mountain ridges, valleys and canyons as well as abundant rivers of rapid currents that drain both the Pacific and Atlantic slopes of the country. In general can be classified into three forest types: seasonal evergreen forest, cloud forest and a seasonal rain forest, this later type being the most representative within the reserve.
The Children’s Eternal Rainforest and other nearby areas have been the focus of numerous studies and vast collections of plants and 
animals. Since the 1960’s, many naturalists, students and biologists have contributed to the knowledge of the cloud forest and other adjacent habitats.
The climatic conditions and the topography of the terrain have allowed for habitat diversification and a high degree of endemism. To date there have been 60 species of amphibians, 101 reptiles, known worldwide as the habitat of the Golden Toad (Bufo periglenes), 425 of birds, including the Three-wattled Bellbird (Procnias tricarunculata), Rufous Motmot (Baryphthengus martii), Piratic Flycatcher (Legatus leucophaius), Bare-necked Umbrellabird (Cephalopterus glabricollis), Rufous-tailed Jacamar (Galbula ruficauda), Emerald Toucanet (Aulacorhynchus prasinus), Summer Tanager (Piranga rubra), Blue-grey Tanager (Thraupis episcopus), Swallow-tailed Kite (Elanoides forficatus), Cherrie’s Tanager (Ramphocelus costaricensis), Buff-throated Saltator (Saltator maximus), Yellow-green Vireo (Vireo flavoviridis), and even the Resplendent Quetzal (Pharomachrus mocinno) as well as various species of hummingbirds, woodpeckers, orioles, parrots, parakeets and many others. Here you can also find 121 species of mammals which represent 50.5% of all terrestrial vertebrate species known in Costa Rica, such as the howler, spider and capuchin monkeys, raccoons, porcupines, peccaries, agoutis, deer, lowland pacas, squirrels, jaguars and tapirs, which is the largest land mammal in Costa Rica and very abundant in these forests. Also, within the invertebrates, it have been reported about 658 species.
The diversity of plant species in the area is also great, there have been reported 3.021 species of vascular plants, a number that corresponds to one third of the total species reported for the country. Other groups classified on the lesser-known flora and are also endemic in the area. For example, approximately 10% of the total flora is considered endemic to the Tilaran Mountain Range, where you can find a variety of trees such as Kapok (Ceiba pentandra), Cedrillo (Brunellia costaricensis), Cirri Blanco or Colorado (Mosquitoxylum jamaicense), Sura or Guayabon (Terminalia oblongata), Laurel or Salmwood (Cordia alliodora), West Indian Laurel Fig (Ficus americana) and several species of ferns, palms, orchids, bromeliads, vines and moss.
Another major objective of the Children’s Eternal Rainforest is the protection of water, due to conditions of geographical location, topography, climate, and principally forest cover, permits a higher richness in the clean water resources within it that are used for human and animal consumption as well as the generation of hydroelectric energy, approximately 50% of the production of electricity originates from this protected area. The main watersheds located in this area are: the Peñas Blancas River, the Esperanza River, the San Lorenzo River, the Aranjuez River, the Caño Negro River and the Guacimal River. Each watersheds has its own composition of different rivers and permanent and temporal streams, as well as innumerable amounts of springs and natural lagoons.
Within the Children’s Eternal Rainforest, you can stay in one of their biological stations, either San Gerardo Station or Poco Sol Station. These are ideal for retreats, workshops, study groups, research projects or vacations. Both offer classroom 
for session groups work, hiking trails in natural forest and regeneration areas with an excellent opportunity to observe and share with the wildlife, the opportunity for a presentation (on request) and delicious Costa Rican meals.
