A Resilient, Arid Ecosystem

North Seymour is a prime example of the Galapagos arid vegetation zone. The island’s dry, rugged terrain is dotted with low-lying bushes, Palo Santo trees, and towering Opuntia cacti, providing a unique habitat for wildlife to thrive.

Despite its harsh conditions, North Seymour Island is teeming with life, making it an unforgettable destination for nature lovers!

North Seymour Island History : A Name with a Legacy

Like many Galapagos Islands, North Seymour has a fascinating story behind its name. It was named after Lord Hugh Seymour, a distinguished English naval officer and landowner during the era of British exploration.

Unlike most Galapagos islands, which later had their names changed to Spanish, North Seymour retained its original English name, making it a rare exception in the archipelago. This historical connection adds to the island’s unique character, blending its natural wonders with a touch of maritime history.

Fun Fact: The Land Iguana Rescue Mission

Did you know that North Seymour Island originally had no land iguanas? That changed in the 1930s, when naturalist Allan Hancock relocated 70 iguanas from Baltra Island (South Seymour) to North Seymour. Thanks to the island’s ideal habitat, with plenty of Opuntia cactus for food, the iguanas thrived and multiplied into a thriving population.

Ironically, this relocation ended up saving the species. During World War II, Baltra Island was used as a U.S. military airbase, and unfortunately, the native iguana population was wiped out due to target practice by soldiers.

Thankfully, in the 1950s, conservationists were able to repopulate Baltra Island using the healthy iguana population from North Seymour. Today, both islands are home to thriving land iguana communities, and for many visitors, the Baltra Land Iguana is the first Galapagos species spotted upon arrival!
