Tsavo Mobile Veterinary Unit - March 2014

Introduction: The month of March was relatively calm compared to drier months of July to September mainly due to the lush green forage covering the ecosystem occasioned by good rains for the last few months

Introduction:

The month of March was relatively calm compared to drier months of July to September mainly due to the lush green forage covering the ecosystem occasioned by good rains for the last few months. In the month an elephant was treated for spear wound for the first time in Tsavo east indicating a new trend of poaching in the Park. Another case of the rare elephants in Lamu with a snare attended to. Rains are expected to subside in the coming months and injuries to elephants assume an upward trend as wildlife are forced  to walk for longer distances in search for water and forage.

Case #1 Treatment of an injured Elephant cow with a bullet wound on the front right leg:

Date: 14th March 2014

Species: Elephant

The wound on the distal part of the front right limb was cleaned with water mixed with hydrogen peroxide, pus squeezed out, doused with tincture of iodine and covered with green clay.                                                                               

Treatment:

Long acting antibiotics, anti-inflammatories and vitamin B12 complex (catasol) was administered to boost the poor body condition. She was declared out of danger and despite assessment of assisting her to wake up she proved otherwise and woke up on her own.

Case #5 Examination of elephant carcasses:

Date: 28th March 2014

Species: Elephant

Sex: one young Male and one Pregnant female

Age: Sub Adult

Location: Pipeline Area, Tsavo East

History:

Two elephant carcasses aged about 4 days from the time of death were spotted near the Aruba- Sala road in Tsavo east national park.

Autopsy:

The area was visited and invasive autopsy could not be carried out due to advanced level of decomposition. Close examination revealed the following:- •    No external injuries were observed. •    The elephants were a young male and a pregnant young female. •    Both died next to each other with no signs of struggle •    Both were facing the same direction. •    All the tusks were intact •    The area is deep inside the park and safe haven of the elephants with very low possibility of poisoning as happens in the boundaries.

Conclusion:

From the deduction above points the most probable cause of the deaths was put as lightning due to the heavy thunderous weather being experienced currently in the region for the last few months. 

Case #6 Treatment of an injured young elephant bull:

Date: 30th March 2014

Species: Elephant

Sex: Male

Age: Sub Adult

Location: Kipini Provisional Forest Lamu

History:

Lamu is an area with few remaining elephant population that are very shy due to the high threats of poaching. This specific young elephant bull was seen near Kipini airstrip after fire razed the area. He was limping and in great pain from a tight nylon rope snare around the front left limb. The vet team was flown into the area and easily found the elephant only 50 meters from the airstrip. He was easily immobilized with 15 mgs of etorphine in a dan inject dart system as he walked to a nearby water point to quench his thirst.

Capture and Treatment:

The rope was cut loose and the deep wound cleaned with hydrogen peroxide mixed with water, tincture of iodine applied and green clay used to cover the wound. Long acting antibiotics, anti-inflammatories and vitamin B12 complex were administered by injection. The anaesthesia was reversed using 48 mgs of diprenorphine Hcl. Close monitoring was advised.

Prognosis: Good

Conclusion and acknowledgement:

The rains are still pouring in Tsavo ecosystem and this is good news as it will keep the heavy feeders like the elephants within the park where it is secure. The case numbers remain low due to the above reasons and also due to heightened security patrols that deter poachers. The unit acknowledges the vital role of its sponsors VIER PFOTEN through the David sheldrick wildlife trust (DSWT) for their continued support to the unit. We also thank the Kenya Wildlife Service management in Tsavo and Nairobi for working with the unit. Report By: Dr. Jeremiah Poghon
