<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 />
