ELEPHANT IDENTIFICATION

To the novice eye, most wild animals of the same species look mostly identical to each other unless marred by a prominent scar or perhaps sporting a different colour variation. However, closer observation reveals that each individual, whether leopard, lion, or elephant, possesses a set of identifying characteristics as unique as human fingerprints. For researchers monitoring these animals, being able to identify individuals is extremely useful for estimating populations and understanding demographics. However, the process is often time-consuming, labour intensive and subject to human bias. For 25 years, the team at Elephants Alive, spearheaded and led by Dr Michelle Henley (last author), have developed their own solution for elephant identification: a System of Elephant Ear-pattern Knowledge (SEEK).

Despite their size, monitoring elephants to estimate populations and demographics comes with its own set of complications. Traditional capture-mark-recapture techniques are expensive, dangerous, and impractical, large-scale aerial surveys are prohibitively expensive, and dung counts vary depending on vegetation type. This has necessitated the use of alternative techniques such as mark-resighting studies which in turn generally rely on photo-identification. The use of photographic records depends mostly on manual matching techniques and human memory, and while automated software models are in use, they still require further development.

The Elephants Alive team monitor elephants across the Associated Private Nature Reserves (APNR) on the western boundary of the Kruger National Park and have been conducting field research since 1996. The team began putting together their own simplified coding system at the start of the period which initially entailed creating detailed drawings of the ear features of individual elephants. The study was officially registered with South African National Parks (SANParks) in 2003 and has continued until the present day.

Very interesting. One of the only few non-biased and factual articles from Africa Geographic.
