Abstract

A representative sample of waterways in Liberia was surveyed for crocodiles, and all three species of African crocodiles were observed. Contrary to previous reports, only Nile crocodiles inhabit the Monrovia mangrove swamps and brackish-water mouths of rivers; there are no slendersnouted or dwarf crocodiles in these habitats. There is partitioning of habitats among the three species in Liberia: Nile crocodiles in mangrove swamps and river mouths (brackish water); slendersnouted crocodiles in rivers through rain forest (freshwater); and dwarf crocodiles in small streams through rain forest (freshwater), some entering the adjacent river. Dwarf crocodiles utilize burrows in the stream banks.

Nowhere are crocodiles abundant, and there is an apparent absence of adults. Although 40% of Liberia is forested, deforestation is occurring rapidly by foreign timber companies and slash-and-burn agriculture practised by the largely rural population. Hunting with firearms, although illegal, is widespread, both for subsistence and commercially, without concern for depletion. Mangrove ecosystems near human population centres are being destroyed. The combination of the above factors has apparently depleted the crocodile populations in Liberia.
