These unwitting traitors were then set free around the islands, irresistible bait for the fugitives. Much of the geographically-specific flora has recovered and is growing once more. Development and implementation of cost-effective methods of eradicating, controlling, and mitigating the impact of invasive species, which has since been used and will continue to be used on other islands and for other species. Karl has more … The project began in response to the massive destruction caused by introduced goats on Alcedo Volcano on northern Isabela, whose population was estimated at 100,000 animals.
