So, how many elephants is too many elephants? It's a question people have wrestled with for ages. Kruger National Park, home to one of Africa's largest elephant populations, has seen their numbers grow from just a handful in the early 1900s to over 31,000 by 2020. That's a lot of elephants! A recent study using smarter aerial surveys and fancy math gives us a more clear picture of just how fast these gentle giants are multiplying. Turns out, since 2013, their numbers have been growing by about 5.3% each year.

This research project deploys satellite tracking collars on ungulates in the GSNL  and monitors their movements as well as other environmental parameters. Its objective is to document movement corridors and identify impediments to migration routes for springbok, oryx and Hartmann’s mountain zebra. Stefanie Urban successfully completed her Bachelor of Natural Resources Management (Honours) project at NUST at the end of 2016. Her project report is available on request.

African elephants (Loxodonta africana) are imperiled by poaching and habitat loss. Despite global attention to the plight of elephants, their population sizes and trends are uncertain or unknown over much of Africa. To conserve this iconic species, conservationists need timely, accurate data on elephant populations. Here, we report the results of the Great Elephant Census (GEC), the first continent-wide, standardized survey of African savannah elephants. We also provide the first quantitative model of elephant population trends across Africa.

Of the animals that had a comparable number of location pings, Oryx 1768 on Keerweder, Hartmann's zebra 1771 on Solitaire and Oryx 1770 on Aandster moved the furthest daily distances with 9.57 km, 7.87 km and 7.35 km respectively. Three animals were collared at the end of July/ beginning of August, including Springbok 132 (after the last one with the same collar id. died in March) and 133, Hartmann's zebra 1775 and 1776. Hartmann's zebra 1776, which is currently ranging on Neuras, moved a considerable mean daily distance of 9.22 km.

Oryx 1770 and Zebra 1771 covered the most distance with 921.62 km and 877.36 km respectively (assuming a straight line between each ping). Mean daily distances have overall increased since the last period, possibly due to isolated rainfall during the period. Zebra 1773 has possibly been killed or the collar fell off, this is currently under investigation. Note: The mean daily distances in the last newsletter were not correct as they were distances between each ping. They should be multiplied by three to get the mean daily distance.

Aerial surveys of the centra] and eastern areas of the Etosha National Park were undertaken during September 1968, April 1969 and February 1970, primarily to establish the efficacy of an aeroplane in counting the larger mammals in the Park and to obtain some idea of the numbers and distribution of the various populations. Previous census methods such as road strip counts and waterhole counts were found inaccurate, unreliable and often impractical in Etosha.
