When we think of the Andaman Sea, we picture turquoise waters and white sand. However, hidden beyond the shoreline lies an essential part of island life — the Andaman beach plants that quietly protect and sustain the coast.
From towering sea pines to delicate sand creepers, these coastal plants are specially adapted to survive salt, wind, and shifting dunes. Moreover, they’re not only beautiful but vital for preventing erosion, supporting biodiversity, and keeping Thailand’s beaches alive and thriving.

🌊 Why Andaman Beach Plants Matter
The plants along the beach aren’t just decoration — they perform essential ecological roles. For instance:
✔️ Prevent erosion – Their roots anchor loose sand and stabilize dunes
✔️ Provide shade and shelter – Vital for small animals and young trees
✔️ Support biodiversity – Birds, insects, and reptiles all rely on them
✔️ Filter salt spray – Thick leaves protect inland vegetation from salt carried by the wind
Without a doubt, these natural barriers help Andaman beaches and islands resist erosion and maintain their delicate ecosystems.
🌿 Common Andaman Beach Plants
1. Casuarina (Sea Pine Tree)
Thai name: สนทะเล
This tall, graceful tree with pine-like, needle-shaped leaves is hard to miss.
🌴 Provides shade and wind protection
🌴 Common along Phuket, Phi Phi, and Similan Islands
2. Terminalia catappa (Sea Almond / Tropical Almond)
Thai name: โพธิ์ทะเล
With broad leaves that turn red before dropping, this tree adds vibrant color to coastal areas.
🌴 Tolerates salt and poor soils
🌴 Provides habitat for birds and insects
3. Ipomoea pes-caprae (Beach Morning Glory)
Thai name: ผักเบี้ยทะเล
This fast-growing groundcover with purple flowers is seen on many Andaman beaches.
🌴 Grows directly on sand, stabilizing dunes
🌴 Known as the symbol of beach resilience
4. Pandanus tectorius (Screw Pine)
Thai name: เตยทะเล
Spiky leaves, large prop roots, and fragrant fruit make this plant stand out.
🌴 Thrives on rocky and sandy shores
🌴 Adds tropical character to the coastline
🌱 Rare or Sensitive Flora to Watch
Unfortunately, due to coastal development, some native Andaman beach plants are becoming rare. For example:
🌿 Sea Hibiscus (Hibiscus tiliaceus) – Yellow flowers that turn orange by evening
🌿 Barringtonia asiatica – Large-leaved tree with fragrant white flowers
🌿 Beach Mangroves – Essential for fish nurseries near estuaries
Therefore, visitors are kindly asked to avoid collecting leaves or stepping on seedlings. Many of these plants take years to establish in harsh beach environments.
