Trend <strong>in</strong> Proportion of Illegally Killed<br />

PIKE is an <strong>in</strong>dex that measures <strong>the</strong> proportion of illegally killed<br />

elephants to <strong>the</strong> total of carcasses found. It ranges from 0.0 (no illegal<br />

kill<strong>in</strong>gs) to 1.0 (all carcasses found are illegally killed elephants).<br />

The PIKE trends across African MIKE sites suggest an ongo<strong>in</strong>g<br />

<strong>in</strong>crease <strong>in</strong> levels of poach<strong>in</strong>g s<strong>in</strong>ce 2006, with 2011 show<strong>in</strong>g <strong>the</strong><br />

highest levels of poach<strong>in</strong>g s<strong>in</strong>ce MIKE records began <strong>in</strong> 2002<br />

(CITES 2012a). The cont<strong>in</strong>ental PIKE level rose from 0.24 <strong>in</strong><br />

2005 to 0.7 <strong>in</strong> 2011, which was higher than that of 2010 which<br />

was at 0.6. Data from <strong>the</strong> first six months of 2012 <strong>in</strong>dicate that<br />

PIKE levels will likely be similar to 2011.<br />

The data make it possible to estimate <strong>the</strong> percentage and<br />

actual number of elephants be<strong>in</strong>g killed <strong>in</strong> MIKE sites.<br />

In 2011, approximately 7.4 per cent of <strong>the</strong> total elephant populations<br />

<strong>in</strong> African MIKE sites were killed illegally. This is a significant<br />

<strong>in</strong>crease from 2010, when <strong>the</strong> average number of elephants<br />

killed was estimated to be 11,500.<br />

Figure 9: S<strong>in</strong>ce 2010, <strong>the</strong> percentage of elephants be<strong>in</strong>g killed<br />

illegally at MIKE sites across Africa has been higher than <strong>the</strong>ir<br />

natural reproduction rate.<br />

Healthy elephant populations have a natural annual growth<br />

rate of between 5 and 6 per cent (Dunham 2012), or a <strong>the</strong>oretical<br />

maximum of 7 per cent (Hanks 1973). Thus <strong>the</strong> 7.4 per<br />

cent estimated illegal off-take <strong>in</strong> 2011 <strong>in</strong>dicates an unsusta<strong>in</strong>able<br />

trend of elephants be<strong>in</strong>g killed faster than <strong>the</strong>y can breed.<br />

If this trend cont<strong>in</strong>ues over a number of years, current poach<strong>in</strong>g<br />

levels will lead to significant population decl<strong>in</strong>es across<br />

much of <strong>the</strong> cont<strong>in</strong>ent.<br />

Sub-regional overview<br />

Central Africa has shown worry<strong>in</strong>g poach<strong>in</strong>g trends for some<br />

time, and has consistently displayed <strong>the</strong> highest levels of<br />

poach<strong>in</strong>g <strong>in</strong> any sub-region s<strong>in</strong>ce MIKE monitor<strong>in</strong>g began. In<br />

2006, PIKE levels were at 0.5, mean<strong>in</strong>g that about half <strong>the</strong><br />

elephant carcasses encountered on patrol <strong>in</strong> MIKE sites were<br />

<strong>report</strong>ed as illegally killed. In 2011, however, PIKE levels had<br />

risen to 0.9. This extremely high PIKE level exceeds any of<br />
