<strong>Isabela</strong>: ground hunting phase<br />

Ground hunters to the rescue<br />

A strategy for dense vegetation<br />

Aerial hunting removed 6,077 animals from Alcedo’s densely vegetated southern slope (see zone of interest in the map). The<br />

remaining goats had become wary of this method and kill rates dropped to 1.5-2 goats per flight hour. In anticipation, ten<br />

water catchments were set up at 3 km intervals throughout this zone. Groups of 2-3 hunters and their dogs were based at<br />

water catchments for 12 days for three consecutive trips.<br />

Hunters´ tracks Goats killed<br />

First trip in January 2005: 3.6 goats per hunter day<br />

Second trip in February 2005: 0.7 goats per hunter day<br />

The images below show hunters’ GPS tracks and positions of goats killed. The second and third trips killed approximately<br />

one-tenth the number killed the previous trip. Aerial hunting was simultaneously conducted around this zone, removing<br />

goats attempting to flee the area. At the end of the third trip Judas goats were deployed in this area.<br />
