Galapagos vegetation has further adapted and diversified due to the range of habitat zones in the Galapagos Islands. There are at least three habitat zones in the Galapagos: the coastal zone (dominated by salt-resistant plants), arid zone (succulent cacti and leafless shrubs), and the highlands (lush Scalesia forests).

What is the climate and vegetation like on the Galapagos Islands?
The islands have a varying climate marked by a scarcity of rain. The coastal areas are quite arid, covered with plants that have adapted to desert-like conditions, but lush vegetation grows in the highlands of the larger islands.
What are the 5 vegetation zones of the Galapagos Islands?
Galapagos Vegetation Zones
- Coastal Zone.
- Lowlands Zone.
- Transitional Zone.
- Scalesia Zone.
- Brown Zone.
- Miconia Zone.
- Pampa Zone.
How did plants get to the Galapagos?
BY AIR. Wind is thought to have played a major role in transporting spores of the lower-form plants, such as ferns, mosses, and lichens, to the Galapagos Islands.The weaker-flying land birds and bats (2 species) likely arrived with the help of the wind.
What plants and animals live on the Galapagos Islands?
9 animals you’ll only find in the Galápagos
- Galápagos land iguana.
- Marine iguanas.
- Galápagos giant tortoise.
- Darwin’s finches.
- Frigatebirds.
- Blue-footed boobies.
- Flightless cormorants.
- Sally Lightfoot crabs.
What is the geography of the Galapagos Islands?
The Galapagos Islands are formed of lava piles and dotted with shield volcanoes, many of which are periodically active. The striking ruggedness of the arid landscape is accentuated by high volcanic mountains, craters, and cliffs.
What is the environment of the Galapagos Islands?
Environmental conditions make the Galápagos a unique island ecosystem. The Galápagos Islands are located near the equator, yet they receive cool ocean currents. This makes for a strange mix of tropical and temperate climates. For most of their history, the islands have been extremely isolated.
What does the Galapagos habitat look like?
The natural environment of Galapagos varies greatly across space. This creates a range of distinct habitats for different plants and animals to live in. In Galapagos, habitats can be classified in many ways. They may be marine or terrestrial, arid or humid and densely vegetated or sparsely vegetated.
Why is Darwin’s cotton only found in the Galapagos Islands?
Galapagos cotton, or Darwin’s cotton, is a shrub endemic to the Galapagos Islands.From this research it is believed that Galapagos cotton colonised the Islands when a seed arrived either on the wind, in bird droppings or floating on the sea.
What is the plant life like in the Galapagos islands?
Pampa Zone. On the islands with elevations over 3000 ft (900 m) the highest vegetation zone in the Galapagos occurs, the Fern-Sedge Zone or Pampa Zone. There are virtually no trees or shrubs, and the vegetation consists largely of ferns, grasses and sedges.
How do plants get to islands?
Also, a lot of plants get to islands because of the wind. Plant seeds often catch a ride in the air. When they reach the island, they get buried in soil and start to sprout. These plants provide food for many animals.
What were the first things on the Galapagos?
The first things to colonise the islands are small and basic organisms (e.g. lichen, algae and mosses), able to cope with the harsh environment. Washed up on the shoreline or blown by the wind from the South American mainland, these pioneer species are the first forms of life on the bare rock.
What are 3 characteristics of the Galapagos tortoise?
Shell functions (Chiari et al. 2009)
- Protection.
- Regulation of body temperature (thermoregulation)
- Facilitation of mating and reproduction.
- Ability to turn over (“self-righting”)
- Locomotion.
- Storage of water, fat, and wastes.
How many species of plants are on the Galapagos Islands?
To date, the Islands are believed to be home to more than 600 native species of vascular plants and approximately 825 introduced species, the majority introduced by humans. More than 100 of the introduced species have become established in the wild, with many of them extremely invasive and of major concern.
What are the Galapagos Islands known for?
Six hundred miles off the coast of Ecuador lies the Galápagos Archipelago: a world unto itself, forged of lava and isolated for thousands of years. The islands are known for their famously fearless wildlife and as a source of inspiration for Darwin’s theory of evolution.
What is the biodiversity of the Galapagos Islands?
The Galapagos Islands are home to some of the highest levels of endemism (species found nowhere else on earth) anywhere on the planet. About 80% of the land birds you will see, 97% of the reptiles and land mammals, and more than 30% of the plants are endemic.
Why does the Galapagos Islands have high biodiversity?
The Galapagos Islands are so biodiverse because of the many different habitat zones that can be found across the Islands. There are coral reefs, highland forests, sand dunes and scrubland, and the changing habitats from island to island. Species diversity is only one piece of the biodiversity puzzle.
What natural process created the Galapagos Islands?
The Galapagos Islands were formed millions of years ago by volcanic activity. Discover how tectonic shifts created the islands and how deep below the sea, organisms thrive in the vicinity of hydrothermal vents.
How did the environment on the Galapagos Islands change?
The Galapagos Islands face many environmental threats. Ecosystem degradation could be caused by: climate change, deforestation, pollution, overfishing, eutrophication and the introduction of invasive species.
How warm is the water in the Galapagos?
Average annual water temperature on the coast in Galapagos Islands is 75°F, by the seasons: in winter 73°F, in spring 72°F, in summer 76°F, in autumn 78°F.
