In 2001, Fauna & Flora International (FFI) in collabor- ation with the Liberian government’s Forestry Development Authority (FDA) established a long-term faunal biomonitoring programme in Sapo NP, which was re-started in 2007 following the end of the civil war (Waitkuwait & Suter 2001, Waitkuwait 2003, Vogt 2011). In 2008, with the support of the Zoologicalet al. Society of London (ZSL), the programme was complemented by regular systematic camera-trappinget al surveys (Collen et al. 2011). Surveys were designed to detect wide-ranging and cameras,cryptic species spaced (Collen at 2 km intervals. 2011). and Following mounted O’Brien 40 cm from (2010) a grid of 32 infrared heat- and motion- sensitive digital centrethe ground, of each was grid set square for a minimum was located of using35 days a GPS and Garmin at 24-hour map 62soperation unit, and mode one in camera each of wastwo secureddifferent in areas an optimal of Sapo location NP.
