Abundance estimates of the Cape clawless otterAonyx capensis (Schinz 1821) and the spottedneckedotter Lutra maculicollis (Lichtenstein 1835)in the KwaZulu-Natal Drakensberg, South Africa

Abstract

Animal signs were used to estimate the abundance of two co-occurring
species of otter in a catchment in the KwaZulu-Natal Drakensberg, South Africa.
In recent years, the numbers of Cape clawless otters appear to have declined
locally, whereas those of the syntopic spotted-necked otter may have increased.
Such results are necessary for the formulation of an action plan to conserve the
otters.
key words: density, abundance, otters, Aonyx capensis, Lutra maculicollis.
