- Trunk and buttress: Massive trunk with a circumference of up to 3 to 4 metres, supported by prominent, fluted base buttresses.
- Bark characteristics: Smooth, pinkish-grey outer bark that flakes off naturally in large thin horizontal sheets.
- Canopy structure: Wide, spreading crown with drooping branches that provide deep shade and bank stabilization.
Agroforestry and ecological importance
Arjun thrives in deep, fertile alluvial soils along riverbanks, canal borders, and ravine edges. Its extensive root system stabilizes river embankments, preventing gully erosion during monsoon floods. Furthermore, Arjun foliage serves as the primary host food plant for rearing tropical Tasar silkworms (Antheraea mylitta).
Sustainable medicinal bark harvesting
The thick inner bark contains valuable cardiotonic tannins, arjunolic acid, and flavonoids widely utilized in Ayurvedic formulations. Sustainable harvesting involves stripping vertical bark patches from only one side of mature trees (over 15 years old), allowing the cambium to regenerate fully without killing the tree.
