The EcoEra Rainforest Reserve, embraces the entire height and breadth of the mountain of Cerro Nara (1,080 meters tall) and its watershed and is adjoined by the Cerro Nara Zona Protectora, an area officially designated as protected rainforest by the Costa Rican government. 

EcoEra is working in collaboration with other groups to establish a biological corridor between Manuel Antonio National Park and the EcoEra Reserve to ensure that genetic diversity is not be compromised.

The EcoEra Rainforest Reserve passes through three life-zones:

• Lowland Rainforest
• Tropical Wet Forest
• Pre-Montane

The Tropical Wet Forest is the most species-rich Life Zone in Costa Rica. Amidst the lush flora, three-hundred species of birds have been documented to date, including the endangered Scarlet Macaw. It is also home to many endangered tropical mammals, including the jaguar, the jaguarundi, the agouti paca and the squirrel monkey.

The reserve is one of the few locations in Costa Rica where all four native species of monkey still reside. It is also home to a plethora of insect, amphibian and reptile species including the Green Iguana, the Ctenosaur, and the remarkable Basilisk Lizard who has the ability to run for up to 50 yards on the surface of the water. The beautiful Morpho butterfly, whose iridescent blue wings span 6', is plentiful here thanks to EcoEra's concerted preservation and planting of its host plants.

Three rivers run through the reserve. The largest is the Rio Naranjo which is 20 miles long and empties into the Pacific Ocean. The 10 mile long Rio Brujo and the 2 mile long Rio Cerra Nara are its tributaries. Numerous small springs and creeks also course through the Cerro Nara watershed. Three magnificent waterfalls grace the reserve; the waters of the Rio Naranjo crescendo at Salto El Nara, a huge waterfall that cascades down from a height of 220 ft. spilling into an inviting swimming hole below. The Eco Era Rainforest Reserve serves as a living laboratory for the study of rainforest biodiversity and offers the opportunity to actively participate in Analog Forestry restoration efforts. The reserve provides a safe setting for practical field experience in all areas of tropical rainforest biology and ecology.
