Title:

Full moon waterhole counts in northern Kunene

Publication Year:
2019
Abstract:

Counts were undertaken at waterholes in the escarpment zone of north west Namibia. In 2018,18 waterholes in 7 conservancies were counted while in 2019, the number of waterholes was increased to 26 covering 10 conservancies. Counts were undertaken over a period of 2, 3 or 4 days during which time all animals seen were counted. Game species differ in the frequency with which they need to visit water resources with some able to acquire much of their hydration needs through foraging. Waterhole counts are therefore best suited to species (like elephants) which make infrequent discrete trips to specific water points to quench their thirst. Estimates of animals are calculated by correcting the numbers seen over the entire count period using the number of count days, and the drinking frequency of the species. They are therefore crude estimates and should be considered a guide to the relative abundance of animals in the area. Values are influenced by several assumptions including drinking frequencies and independence of sightings. Based on assumed drinking frequencies of 2 days for black-faced impala and 1.8 days for elephants, the total estimated number of animals at waterholes was 754 and 212 respectively in 2018. In 2019 a very similar number i.e. 740 was estimated for black-faced impala while the estimate for elephant was approximately half that of the 2018 value at 121.
