Between 23 -28 October 2007, eight elephants were collared in the western Hoanib River (2 elephants), Hobatere Game Reserve (4 elephants) and Omusati regions (2 elephants) with GPS collars provided by Data Scout (SA). Three other elephants were de-collared (these elephants had been collared in previous collaring exercises). As of April 2008 all of the new collars had failed. This was because of either the removal of the collars by the elephants or the failure of the collars due to a poor batch of batteries having been provided by the manufacturer to Data Scout. Data Scout has undertaken to provide an additional 8 collars to the project free of charge to compensate for the lack of durability in the current collars. They have also undertaken to part-fund the next collaring to reduce the cost to the Namibian Elephant and Giraffe Trust (NEGT). Behavioural studies have continued and the heavy rainfall during the 2008 wet season has resulted in a change in feeding behaviour from mostly browsing during "normal" years to mostly grazing during the current year. It is too early to tell whether the increase in the abundance of vegetation will have any effect on the elephants' reproductive potential.
