Research in Arabuko-Sokoke Forest

Eleventh Meeting of the African Amphibian Working Group, 19-21 April, Watamu, Kenya
1.25 MB PDF. Requires Acrobat Reader.

The Arabuko-Sokoke is Kenya's last remaining coastal forest. It is but 400 km2 in area and located approximately 60 miles north of the port of Mombasa.

The Arabuko-Sokoke is about 25% primary forest and is characterized by the tree genera Afzelia, Brachylaena, Brachystegia, Cynometra and Manilkara, among others.

The author's study area is a large 10 hectare2 clearing in the forest, created many decades ago by excavations by the Kenya Glass Company. During the two dry seasons, January-February and June-September, there is almost no free water available in the Arabuko-Sokoke Forest.

During the rains, the study area is inundated, pools form some of which can be up to 70 cm deep providing breeding sites for over 20 species of frogs.
