Floreana island has a particularly interesting social history. According to reports it was the site of the first ‘post office’ used by travelling whalers, and home to the very first settler in Galapagos, an Irish sailor named Patrick Watkins. It was also the first island colonised by Ecuadorians, and today is home to a small population of around 140. This small community is proud to live alongside some of the Archipelago’s most unique flora and fauna. Much like the other inhabited islands in Galapagos, however, Floreana has suffered from the introduction of damaging, non-native (invasive) species by humans and the impact has changed the landscape significantly.
The introduction of invasive species has had devastating effects on Floreana’s local wildlife. 55 species found on the island are currently listed on the IUCN Red List, including two that are critically endangered. 12 species are now locally extinct, including the Floreana mockingbird and Galapagos racer, the reason for which is widely thought to be due to introduced cats and rats. Fortunately the racer and mockingbird have survived on the neighbouring islets of Champion and Gardner where such invasive species are not present, and other locally extinct species are found elsewhere in the Archipelago.
GCT is supporting Island Conservation and other project partners to undertake one of the largest, and most complex, eradication projects ever conducted on an inhabited island, with the ultimate goal to reintroduce locally extinct species to Floreana. To date no project has ever successfully removed invasive rats and cats from such a large inhabited island. Engagement and leadership by the local Floreana residents is crucial for this restoration project to succeed. Fortunately, the Floreana community is fully committed to preserving and restoring their local wildlife. The eradication of rats will also benefit the local farmers as invasive rats decimate crops and eat livestock food. To ensure native species are not impacted, bait trials and mitigation methods will be conducted to inform implementation plans.
The long-term goal of the project is to create a healthy, thriving ecosystem on Floreana island by restoring it to its former glory, including reintroducing species that have gone locally extinct as a result of invasive species.
In addition to the restoration work, we fund the Floreana mockingbird and racer reintroduction projects that aim to bring these species back to their rightful home. The team will continue monitoring the populations of Floreana mockingbirds and racers on Champion and Gardner islets, the data from which will be essential for planning reintroductions to Floreana. Initial surveys have been undertaken on Floreana to assess habitat suitability for their reintroductions and, once invasive species have been eradicated, the team will pave the way for the reintroduction of these, and other locally extinct species to Floreana.
