Galapagos Tortoise Survey – Isabela

September 20, 2011 § Leave a comment

A group of six guards and three staff of the Charles Darwin Foundation made a census of Galapagos Giant Tortoises Geochelone guntheri the species in the Sierra Negra volcano on Isabela Island (Galapagos), to check their population status.

The census was conducted in San Pedro sites, Roca Union and Humedales of Sierra Negra volcano. So far there have been three trips, which lasted 16 days.

On each trip the area was surveyed by zones, the park rangers observed the tortoises and verified from their tag if they had been repatriated or born in the wild. Additionally, they measured the long curve of each turtle, to measure the growth of subsequent monitoring and compare with the last census.

Partial results have counted 23 tortoises in the Humedales surveyed, 26 in San Pedro and 23 Rock Union. Final results of the survey will be announced soon and the national park will announce the population numbers of this species of tortoise.
