This Secondary Area is defined by the range of Rusty-necked Piculet Picumnus fuscus, which is known from fewer than 10 specimens all collected along 500 km of the middle Guaporé river, which follows the border between Brazil (in Rondônia state) and Bolivia (Beni department) between Pimienteiras and Guayaramerin (see map, p. 236). Parker and Rocha (1991) found the piculet to be fairly common in seasonally flooded forest along the Guaporé; the region appeared largely uninhabited and the riverine forest undisturbed. A large portion of this species' range apparently lies within the Guaporé State Biological reserve, in Rondônia (6,000 km²).
