College student Kelli Simkus explores the ecology and problems facing the Galápagos Islands, due to the introduction of non-native plant life, animals and the invasion of humans on this island paradise.
(congratulation, well done with plenty of info…RHT)
The Galápagos Islands are a group of volcanic islands that consist of 13 main islands and six much smaller islands. There are several rocks and islets in this region. The Galápagos Islands are south of Mexico, and 600 miles west of Ecuador on the Equator. The uniqueness and beauty of these islands have brought humans to the islands for the last couple of centuries. Due to whalers, pirates, sealers, tourism and the weather, the Galápagos Islands have been placed on the World Heritage List for being in danger in 2007.
These islands are in severe need of help if the marine species are going to continue to exist. Distinct Eco-Zones The Galápagos Islands are home to many forms of wildlife in the area. The Galápagos Islands are divided into three distinct zones. It depends on the condition of the zone as to where the wildlife lives. There is the littoral zone; this area is a narrow stretch of arid lowland that can be found along the shoreline between high and low water levels. The plants found in this area are rooted, like the mangrove and common shrubs like slatbush. Beach morning glories grow on the beaches. They help stabilize the beach. (World Wildlife, 2001) There is the arid zone, which is a region where evaporation exceeds precipitation. It is inland of the littoral zone and covers most land in the Galápagos ecoregion. There are many species of cactuses that inhabit the arid zone. Finally, the third zone, the humid zone, is sometimes called the transition zone. The transition zone has arid to moist temperatures. These are areas on islands that reach elevations of 1,000 feet. Here you will find a combination of vegetation types and species.
