The goal of Project Isabela, initiated in 1997 and completed in 2006, was to eliminate large introduced mammals from northern Isabela Island (approximately 250,000 ha), Santiago Island (58,465 ha), and Pinta Island (5940 ha). The project began in response to the massive ecosystem-wide destruction caused by introduced goats on Alcedo Volcano on northern Isabela. At the start Project Isabela, the goat population on northern Isabela was estimated at 100,000 animals. Eradication work began on the smallest of the islands – Pinta – which was used as a training ground, then shifted to Santiago prior to the arrival of helicopters, which were essential for work to begin on northern Isabela.

According to scientists from the Giant Tortoise Restoration Initiative (GTRI), a project of the US nonprofit Galapagos Conservancy, Inc., the results from a recent expedition to Alcedo Volcano in Galapagos to conduct a census of the tortoise population there exceeded all expectations. WASHINGTON (PRWEB) February 08, 2021 Researchers with the Giant Tortoise Restoration Initiative (GTRI) on an expedition to Alcedo Volcano in the northern part of Isabela Island, Galapagos, recently conducted a complete census of the tortoise population there ( Chelonoidis vandenburghi ), resulting in population estimates far surpassing what was expected for this species. A total of 4,723 individual tortoises were located and marked, and scientists on the expedition noted the remarkable recovery of the region’s habitat overall following the eradication
