The Neram tree (Dipterocarpus oblongifolius) is a fairly common inland riverside tree in the north-eastern half of Peninsular Malaysia and also throughout most of Borneo (Sarawak, Brunei, Kalimantan, and parts of Sabah). It seems to be absent from the West Coast states, although strangely, seems to be present at the Ulu Kenas Recreational Forest park, near Kuala Kangsar in Perak (which is an exception). In Pahang itself, it is not found in all areas, and therefore can only be considered as locally common. In Sarawak, it is called the Ensurai tree.
The Neram tree is a dipterocarp which may surprise some people as dipterocarps are normally associated with straight and tall timber trees in the South East Asian rainforests. The Neram is anything but straight and tall, although it can grow to more than 2 meters in diameter and reach perhaps 40 meters tall. The trunk and branches tend to lean out over the water’s edge in order to facilitate its fruit dispersal.
This beautiful tree is very important for protecting riverbanks which would otherwise get eroded away during floods. As such, the tree is accorded some form of protection status in Sarawak. The Neram also plays a vital role in Kelah (Tor Tambroides) conservation as its fruit is eaten by those fishes (a fruiting drought some years ago decimated the Kelah population).
The fruit consists of 3 very short wings and two main pink colored wings that are about 8 – 10 cm long. The leaves are dark green and shiny, about 15 – 18 cm long, and with prominent ridge veins. The bark is fairly reddish-brown with dimples, and somewhat flaky as well.
Kayaking along inland rivers with the huge Neram trees arching over the river and providing much valued shade is a great experience, and only possible where they are found. Their boughs, branches, and trunks are often festooned with numerous epiphytes, ferns, and orchids, and when they fall into the river through old age, their enormous trunks provide a convenient natural bridge to ford the river.
Neram trees can be found throughout Taman Negara, where they line almost all the riverbanks there, although they seem to be absent from the other major conservation areas in Peninsular Malaysia, such as Endau Rompin National Park and Royal Belum State Park (as far as I know). They are impossible to miss throughout their range, as they are distinctive, large trees which tend to colonize entire riverbanks. Some magnificent stands of tall Neram trees may still exist along rivers flowing down the eastern flank of the Main Range in Pahang, such as at the beautiful Ulu Jelai (upper Jelai river), site of a proposed conservation area for many years, but which never got anywhere.

Dear Sir, thank you for the great site. I am from Beaufort, Sabah. I am currently planting lots of neram seedlings about 16-20 inches tall amongst my palm plantation. I was wandering if these neram trees will grow straight in the future. I am lucky in a sense that neram trees are plentiful along a river near my plantation which is next to a forest. Likewise i am planting a few other Shorea species too, namely S. pauciflolius, S. johorenesis and D.lancelotius( need spelling check on that word for spear shape in latin) . If you have more advice or information please let me know, i am doing my part so that future generations can view these beautiful trees close up. One other question if i may, what is the name for this tree species, it has dots at the ends of the leaf’s viens and the leaf is spear head shaped. Thank you very much.

I think it’s good that you are interested in planting our beautiful Malaysian forest trees. I think your spelling should be Shorea pauciflora, Shorea johorensis, and Dryobalanops lanceolata. I’m sorry I don’t know what tree you are referring to in your question, but good luck. Maybe you can start the next FRIM in Sabah. FRIM started off as a forest plantation on almost barren land, but look what they have become today.

Dear Sir, thank you very much for your encouragement. I will certainly do my part as a Malaysian! I would like to pass on some pictures of that forest plant with the spotted leaf, if i can e-mail you. Thanks again! Ghani.

I love this tree…it’s one of the most beautiful trees I’ve seen in the world!!another one is probably the weeping willow tree:) .I consider myself a sport angler,fishing from the drain,upper river jungle,sea and even ice fishing in artic circle.
Ensurai as we call it here in Sarawak,is blessed for its ‘never straightness’…that spare them from being use as timber,even since the older days.And they can almost grow on rock with almost a slight present of soil by the river bank.They only give up to bizarre flood or the big part of the bank give away.Dead trunks and branches fall into river provide homes and shelters to many river dwellers like masheer,hampala,upper river snakehead and others.
The more you look at these trees,the more you appreciate them.Cruising through on a longboat ride underneath their arch give me a feeling that you are entering Rivendell…thus we shall keep these Ents and our other nature beauties that we borrow from the future generations…
If words are not enough, pictures in my blog may give you better story of this living paradise..😎

Gentlemen, I’m interested to plant Neram tree. Where can I get the seedlings in Selangor? Appreciate your sharing.

I’m not sure, but you can ask the FRIM in Kepong.
