Once the animal was sufficiently sedated, the capture team would rope it down, blind fold it, and the antidotes injected into the jugular vein. Etorphine was reversed with Diprenorphine Hcl (M5050®) at 3x the dose of Etorphine used, while xylazine was reversed with 5mg Atipamezole (Antisedan®). Both drugs were given in the same syringe and the respiration monitored to determine the response to the antidotes. It was judged adequate if deep and regular, and the mucus membranes moist and pink. The response in all animals was satisfactory and no additional antidotes were given. Twelve-mg of M5050® were also given intramuscularly to take care of any re-narcotisation that may occur. The condition occurs when M99® is re-cycled either from the enterohepatic circulation or redistribution from adipose depots. Each animal was also given a broad spectrum amoxycillin based antibiotic (Betamox®) intramuscularly and Ivermectin (Ivomec®) to treat internal and external parasitism. Meanwhile, it was processed for loading into the recovery trailer and after loading it was transported in the same to the release site. It was transported blind folded to reduce stress from visual stimulation. The animals were released into a holding facility for a few hours for observation of any complications that may have arisen during capture and transportation before being free released. The exercise was very successful and no mortalities were experienced. Very high mortalities during giraffe capture have been documented.
On the afternoon of 14th, the proprietor of King Fisher tented camp near Sala Gate within Tsavo East sighted an elephant calf wandering alone 15km from Sala gate along the Galana River. After ascertaining that there were no other elephants in the area and it was either orphaned or separated from its mother and/or family, he promptly called the unit for rescue. Together with the de-snaring team we responded immediately. The calf was found in the same general area with no other elephants on sight. The age was estimated to be about 15 months but initial report indicated that it was only a few months old. We proceeded with the rescue exercise. It was restrained physically, the legs properly secured, loaded into the vet truck and transported to the Voi orphanage for an overnight stay. It was airlifted to the Nairobi nursery the next day. Reports so far indicate that the calf is doing very well and has already acclimatised.
Amboseli national park reported an elephant with two spears still embedded on its head on the 17th. The elephant identified as Odile, the matriarch from the OB family, was on sight and required immediate attention before it retreated back into the swamps. They arranged for me to be airlifted immediately by an aircraft belonging to the Amboseli Elephant Research Project. However, it couldn’t be possible for me to be brought back thus the vehicle had to follow. The elephant was found to have moved deep into Solanum incum (Sodom’s apple) bush near Oldare area by the time we arrived. It took nearly three hours of manoeuvring and aerial support to get to it. The first dart composed of 17mg Etorphine Hcl landed perfectly on the left thigh but the animal did not show any signs of narcotisation. After 25 minutes and still no sign at all, it was given another full dose. On dart impact, it fled into an even thicker bush. The terrain was extremely difficult to effectively herd it to go down in an open area. It went down after about 10 minutes but accessibility proved extremely difficult and it took almost 7 minutes to get to it. The spears, one at the temple and the other at the base of the trunk, were deeply embedded and required several men to pull out.
Both were about half a foot deep. The wounds were cleaned thoroughly and treated with a cloxacillin based antibiotic ointment (Opticlox®) and a tincture of Lugol’s iodine. The animal had three other spear wounds which were however not deep. They were at the left rump, near the base of the trunk and at the mid lumbar vertebral area. They were also cleaned and treated the same way as the other two. The animal was also given a high dose of long acting and broad spectrum Oxytetracycline (Oxykel®). After ascertaining that there was no other injury, the animal was revived with 60mg of Diprenorphine Hcl intravenously.
The unit will be kept updated on its progress and if not satisfactory a repeat treatment will be considered. At the time of preparing this report however, it had not been found and efforts to find it are ongoing. Odile had a family of 14 individuals. It was speared while defending its family against Maasai morrans on a revenge mission on claims that one of their cows had been killed by elephants while watering their animals within the park. It became separated from its family after the incident. Before we left for Tsavo the following day, an aerial survey was done to try and locate the family. Ground searching by vehicle was resorted to facilitate more detailed observation of families seen during the aerial survey. Fortunately, the family was found near the Research camp. One of the cows was observed to have an infected spear wound on its right shoulder but the rest were unharmed. The wound was discharging pus and the animal seemed to be in some pain as it occasionally avoided bearing its full weight on this leg. It also kept on scratching the wound. We decided to treat it in order to arrest the infection before it spread. It was immobilised with 17mg M99® and went down in about 7 minutes on its sternum. We quickly rolled it over onto lateral recumbency to prevent respiratory complications that arise on sternal recumbency. The pus was cleaned out and the wound treated in the same way like the above elephant.
An antibiotic cover of LA Oxytetracycline (Oxykel®) was also given intramuscularly at different sites. The animal was thereafter revived with 60mg of Diprenorphine Hcl (M5050®) injected into an ear vein. It stood up in two minutes.
At the time of preparing this report, neither the matriarch nor the family had been found after treatment. The unit is in touch with Amboseli for an update when found. Just before embarking to treat the above elephant, we received a radio message from Voi that Nepasha, an orphan at the Ithumba orphanage, had a piece of stick piercing its left fore leg. The leg had become swollen and painful. We left Amboseli for Voi in the afternoon and proceeded to Ithumba the following day (the 19th). The calf would not allow anybody to touch that leg and physical restraint to facilitate treatment proved futile. The stick was deeply embedded and had no grip to allow its removal without proper restraint. The calf was therefore given 3mg Etorphine Hcl by hand injection to cause mild narcotisation to allow physical restraint and administer treatment. The stick measuring about 2 inches in length was subsequently removed.
The wound was slightly infected and was cleaned and an antibiotic ointment applied. Two tubes of the antibiotic ointment were given to the keepers to apply the following two days. An antibiotic cover was also given intramuscularly. The calf was thereafter revived with Diprenorphine Hcl given intravenously. A report received while preparing this report indicates that the swelling has subsided and the gait has now normalised.
On the 24th August, the unit was requested by the management of Tsavo East Park to help assess the possible cause of death in an adult elephant at Dakota ranch on the southern boundary of the park. The carcass was however in an advanced stage of decomposition (at least one week old) to do any autopsy. However, foul play is suspected as the tusks were missing.
KWS rangers have already recovered them from livestock herders in the privately owned ranch. We could not tell how it was killed but we suspected poisoning with an arrow. There was a skin breakage at the right rump which looked to have occurred ante-mortem. It measured about 3 inches in length and was possibly caused by an arrow. We latter observed three groups of over 50 elephants each come to water at a nearby cattle trough. None was observed to have injuries.
