Description and Ethnobotany
| Growth Form | Shorea robusta is a large tree 45-50m tall; trunk to 5m dbh (diameter at breast height). However, most trees would normally attain a height of 18-32 m, with a dbh of 1.5-2m. |
|---|---|
| Crown | The Sal tree has a spreading and spherical crown |
| Trunk | The bark is deeply fissured in younger specimens of Shorea robusta, but the fissures gradually becomes more shallow as the tree matures. |
| Roots | This species has a tendency to develop a long and deep tap root even at a very young age. |
| Foliage | The leaves of the Sal tree are oblong to oval, 10-20cm long by 6-12 cm wide, with 12-14 pairs of lateral veins. |
| Flowers | The flowers of Shorea robusta are cream- yellow, about 2cm across, and are carried in large and showy clusters. The flowers are pollinated by Thrips (Insects from the order Thysanoptera). |
| Fruit | The small fruit is oval in shape and measure about 0.8-1 cm in diameter. Each fruit comes with 5 wings that measure 5 - 7.5 cm in length, and of which 3 are longer than the other 2. |
| Habitat | Shorea robusta occurs in deciduous (moist or dry) forests and can be found from sea level to about 1,500m. However, it is not common above 1,000m above sea level. It is estimated that the Sal tree makes up some 14% of India's total forested area. It is likewise dominat in some parts of Nepal. |
| Ethnobotanical Uses | Edible Plant Parts : Edible Seeds Food (Fruit or Vegetable): In India, the seeds are also cooked into a porridge with other ingredients. The seeds are also ground into a coarse flour to make bread, and oil from the seeds of the Sal tree is also extracted commercially and used as a substitute for cocoa butter. The 'Seed butter' is also used in cooking, and the plant itself is also consumed, but only as faine food. Timber & Products: In India and parts of Nepal, Shorea robusta is the predominant hardwood species that is used in construction, where it is used in the building of houses, ships, railway cars, as well as in hydraulic engineering. The wood is highly resistant to termites, and very durable. Agriculture - Forestry: Shorea robusta has been grown alongside with Tectona grandis (Teak) in mixed plantations, with good results. Others: The leaves of Shorea robusta are also harvested to make hats, as well as lacquered plates and bowls. The leaves are also used as cattle fodder. |
