Camera trapping in Sapo National Park

By on March 6, 2008 in EDGE Updates, Uncategorized

Our first day in Sapo, we met up with Konie our EDGE fellow. While Konie is experienced at biomonitoring, camera trapping is a new skill for him, so we set about the training programme in remote monitoring using camera traps. The fundamentals of camera trapping operation, placement, maintenance, site selection and deployment were taught to a large group for FDA and FFI employees and University of Liberia students, along with GPS training.

The team then prepared for the six day trip into the forest to establish the camera trap grid.

Sapo is a challenging environment to implement a camera trapping monitoring scheme. The park border is a one hour walk, and a canoe ride away from park HQ.

The grid of cameras we set out formed an 80 km2 area from the park border. There is no vehicle access, and very few pre-established trails. Therefore the majority of the time, the teams were cutting new trails into the park, and navigating by a combination of GPS, compass and the sun (when the satellite coverage failed and the compass was lost).

Each of the two teams were covering more than 20 km a day in order to establish the 32 cameras within the six day period. All did amazingly well, considering the majority of the group were new to the operation and deployment of camera traps and GPS navigation. The thickness of the forest really dictated our speed, with some frustrating days of only one camera being established.


At the end of the six days, the teams returned exhausted, but having successfully put out all the camera traps.

We had seen several signs (dung and footprints) of pygmy hippos during our time in the forest. Now all we had to do was wait…
