Fortuna Forest Reserve protects the watershed of the Fortuna Dam, a major hydroelectric project completed in the mid-1990s. It includes the upper watershed of the Chiriquí River, plus an area in the southwest outside the watershed. On the Pacific side of the continental divide, it contains rugged terrain, with the high point, Cerro Chorcha (2,213 m), in the southeast, and the low point (700 m) in the southwest. The Oleoducto (Pipeline) Road between lowland Chiriquí and the town of Chiriquí Grande in Bocas del Toro traverses the reserve.
The globally-threatened Bare-necked Umbrellabird occurs north of the reservoir, but is rare. Fortuna is the western end of the range of the globally threatened Yellow-green Finch, which is uncommon at higher elevations south of the reservoir. The globally threatened Red-fronted Parrotlet is occasional, while Three-wattled Bellbird is present seasonally in small numbers. Among near-threatened species, Black Guan and Blue-and-gold Tanager are common, Resplendent Quetzal uncommon at higher elevations, and Great Curassow is rare, and there is apparently only one record of Resplendent Quetzal. Fortuna contains 38 of 54 species (70%) of the Costa Rica and Panama Highlands EBA, and 38 of 68 species (56%) of biome N06. It also contains a few species of the Central American Caribbean Slope EBA: Lattice-tailed Trogon, Black-crowned Antpitta and Black-and-yellow Tanager. It and the adjacent Palo Seco Protection Forest are the only known sites in Panama for Ashy-throated Bush-Tanager, and also the only place where Strong-billed Woodcreeper and White-bellied Emerald have been recorded recently (Ridgely and Gwynne 1989, Robbins et al. 1995). Since 1976 the area has been extensively studied by ornithologists (Ridgely and Gwynne 1989, Robbins et al. 1995).
