Sanparks Statement on the Knysna elephant

In 1876, the Knysna elephants, that freely ranged the forest and fynbos areas in the southern cape, numbered about 500 individuals. The numbers declined rapidly as increasing numbers of woodcutters and hunters settled in the area. By 1908 the population status was estimated at 20 individuals, dwindling further to an estimated 11 by 1970. By 1980 a mere 3 individuals were believed to still roam the area.

Failed introduction
Knysna elephants formed the southern-most natural population of the species. In 1994, three young female elephants where introduced from the Kruger National Park in an attempt to sustain the presence of elephants in the Knysna forest area. The translocated elephants did not remain within the largely forested conservation area but progressively chose to range in more open habitat on private land, and were eventually relocated to the Shamwari Game Reserve in the Eastern Cape.

Assessments of population status 1994
In 1994, soon after the introduction of the Kruger elephants, an assertive effort was made to verify the population status of the Knysna elephants. The results revealed a worst case scenario of a single surviving elephant:
• A ground census (sweep) did not produce any evidence for the existence of more than one animal;
• The spatiotemporal structure of fresh elephant signs (dung, spoor, breakages, etc.) and physical sightings, recorded from 1990, was consistent with a scenario of a single surviving elephant;
• Photographic records of 1986, 1992 and 1994 all appears to depict the same animal;
• There was no verified evidence of more than one elephant seen together beyond 1992.
Ten years later, in 2005, available information and monitoring data were analysed again. These results, again, pointed towards a scenario of a single surviving elephant:
• There were, again, no verified reports of more than one elephant seen together;
• As in 1994, all observations (sightings, dung, spoor, breakage, etc.) were consistently spatiotemporally staggered, i.e. never were signs of elephants originating from more than one locality at the same time recorded for the preceding decade;
• Detailed comparison of available photographic material (also considering tusk breakages that could result in diverse tusk configurations) did not produce conclusive evidence for more than one elephant.  It was decided to continue with structured monitoring and pursue additional high resolution photographic material.

No reliable evidence for more than one elephant
Today, three and a half years later, the spatiotemporal staggering in monitoring data is still consistently sustained. The additional photographic material obtained can be related to previously existing material, inter alia through comparing ear serration patterns. Considering the above, South African National Parks concludes that there is no reliable evidence for the existence of more than one Knysna elephant.

Future management
To verify the population status, the current monitoring programme to record elephant-related observations (sightings, dung, spoor, etc.) in a structured manner, together with the regular analysis of data, and the gathering of photographic material, will continue.

2007 survey suggested at least 5 elephants
Following the findings of a study by external researchers, using faecal DNA to quantify the population size, indicating that there are at least five remaining Knysna elephants (Eggert et al. 2007), SANParks have embarked on a parallel study which, is still in its initial stages.

Habitat unsuitable for elephants in current state
It is maintained that the poor reproductive performance and population decline of the Knysna elephants are attributed to dietary constraints in the predominantly forest environment to which they were largely confined as a result of residential and agricultural/forestry development in the region (Seydack et al. 2000). A viable elephant population can only be established if suitable additional habitat is obtained and added to the forest/fynbos areas currently within the jurisdiction of SANParks. Considering the constraints with confining such a population to the larger conservation area, and the fragmented and open-access nature of the envisaged Garden Route National Park, this is currently not considered to be a viable management option.

An interesting snippet I came across, demonstrating how the interest of one conservationist can energize many into action.

Dalene Matthee the SA author of ‘Circles in a forest’ (1984), wrote a fascinating novel about the extermination of the elephants and the exploitation of the woodcutters of the Knysna forest. In this novel she uses some of the original photos taken by an ardent supporter of the elusive Knysna elephant - Mr. D.Duncan.
Mr. Doug Duncan a former pilot, farmer and conservationist - lived in the Brackenfield area during 1968-75. During this time he became fascinated by stories he had heard from the locals, of these huge ‘ghosts’ moving silently through the thick forests.
Stories abounded of secretive beasts glimpsed in the heavy shadows, enormous footprints temporarily etched in the sand of narrow forest trails and large pieces of dung (believed to have miraculous health benefits and used by locals as an ingredient in soup).
Such stories were frequent amongst the locals, but it was only when coupled to the data of findings from two scientific surveys (1968-70) that interest in these forest elephants heated up. Regardless of scientific figures and estimates - there was no absolute visual confirmation available as regards the elephant type and characteristics. Importantly, the public needed to be energized by visual imagery to verify any academic surveys - something to make it all the more ‘real’ for the public imagination.
Enter Mr. Doug Duncan – he spent months tracking the elusive pachyderms through thick forests in the Diepwalle/Harkerville area, being chased and nearly cornered by them on a number of occasions. But finally his patience and diligence paid off and he was rewarded by taking the first photographic records of the bull elephant ‘Aftand’ and two others from the small herd.
These photos are amazing and show the gentle giants grazing in an open patch of forest. The photos provided the first absolute visual record for ‘Joe Public’ that elephants existed in the Knysna forests and thereby offered the imagery necessary to start the fledgling support to protect this precious herd; which has been part of the mystique and magic of the forests where they have roamed for hundreds of years.
