Only 300 to 400 more remaining...
The El Hierro Giant Lizard is a very large lacertid that can grow beyond 20 cm in length, and lives only on the Hierro Island of Spain's Canary Islands. It used to exist in a broader area but now only exists in a certain part of Hierro Island. Their number is down to a mere 300 to 400, including those returned to wilderness by humans.

Nationwide efforts to protect the El Hierro Giant Lizard
The number of El Hierro Giant Lizards has dropped because of a scarcity in food plants and an increase in attacks by seagulls and other animals. Although the extent of human-induced changes to the ecosystem is unknown, with so few El Hierro Giant Lizards in existence, any further human-induced changes to their environment could cause them to go extinct in a flash. To avoid this tragic scenario, Spain has enlisted the entire country to help protect the El Hierro Giant Lizard.
