General Information
Shorea trapezifolia is a large tree.
The tree is harvested from the wild for local use as a food and source of wood.
Regeneration is good where selective logging is taking place, but most of the habitat has been converted into plantations, resulting in the species becoming localised. The plant is classified as 'Critically Endangered' in the IUCN Red List of Threatened Species(2013)[

Propagation
We have no specific information for this species - the information below is a general guide for the genus.
Seed - best sown as soon as possible. It does not require pre-treatment, but it is recommended to soak the seed for 12 hours prior to sowing[
]. The seeds are sown in seedbeds, where they are covered with a mixture of sand and soil (1:1) or with a thin layer of sawdust[
]. Germination of fresh seeds is usually good and rapid. About two weeks after germination, when the seedlings are 5 - 6cm tall, they are potted up into individual containers about 15 x 23cm with good drainage holes at their base[
]. It is normally recommended to use a mixture of forest soil and sand (at a ratio of 3:1) as the potting medium in order to introduce the appropriate mycorrhiza to the roots. The seedlings are placed in 50 - 60% sunlight and watered twice daily[
].
Seedlings can be planted out when 30 - 40cm tall - harden the seedlings off in full sunlight for one month prior to planting[
].
