Useful plants

Wood, fibre, shelter and craft

Sal

Shorea robusta

Useful plants

Identify: Tall straight tree; thick leathery oval leaves with prominent veins; winged fruits; rough dark bark.
Habitat: South Asian monsoon forest and foothill plains.
Season: Wood year-round; seeds seasonal.
Field use: Very strong construction wood, durable fuel and leaf plates; resin and seeds have documented regional uses.
Caution: Heavy wood is poor bow-drill board material. Harvest is regulated and forests are often protected.
Look-alikes: Dipterocarps share winged fruit; local identification is needed.

Useful plants

Stylized form diagram for Banyan and strangler figs

Identify: Milky latex; alternate simple leaves; aerial roots from branches; fig fruits with tiny internal flowers.
Habitat: South Asian and tropical forest, village groves and riverbanks.
Season: Fruit varies; roots and fiber year-round.
Field use: Aerial roots and bark fiber provide cordage; dry roots and wood make light friction-fire materials; ripe figs of known species feed people and wildlife.
Caution: Milky latex irritates. Many figs are edible but some are poor; sacred or owned trees must not be damaged.
