Vegetation Zones of Ecuador: From Coast to Amazon to Galápagos

Ecuador's extraordinary biodiversity stems from four distinct vegetation zones packed into a Colorado-sized country:

1. Coastal Lowlands (Costa)

• Tropical Rainforest: North coast (Esmeraldas) — mahogany, balsa, rubber, high endemism.
• Mangroves: Estuaries (Guayas, Cayapas) — critical nurseries for marine life.
• Dry Forest: South coast (Manabí, Santa Elena) — deciduous, drought-adapted (ceibo, palo santo).

2. Andes Mountains (Sierra)

• Cloud Forest (Bosque Nublado): 1,800–3,000 m — perpetual mist, epiphytes (orchids, bromeliads, mosses), spectacled bear habitat.
• Temperate Forest: 2,500–3,500 m — alder, oak, laurel, polylepis (paper bark tree).
• Páramo: 3,500–4,500 m — unique high-altitude grassland with frailejones (Espeletia), cushion plants, glacial lakes.

3. Amazon Rainforest (Oriente / Amazonía)

• East of Andes — hyper-diverse terra firme and várzea forests. Canopy >40 m. Thousands of tree species, lianas, palms, orchids, medicinal plants. Yasuni National Park: world's highest biodiversity per hectare.

4. Galápagos Islands

• Volcanic origin, arid lowlands (cacti: Opuntia, Jasminocereus; Palo Santo), humid highlands (Scalesia forests, Miconia), mangroves. High endemism: giant tortoise, marine iguana, Darwin's finches.

Ecuador holds ~10% of Earth's plant species in 0.2% of land area—a megadiversity hotspot.
