[Mastwatch] Shorea albida

Hi ewverybody,



All interesting, including Colin (Maycock?) at Danum who says there has been little drought up there to date, - out of kilter with Sunda further west as so often. But there is another potentially intriguing aspect of this issue which UBD sleuths can get on to, and for which I have brought Ian Baillie in as he has had an interest in the coastal climate of NW Borneo: Primary seringawan forest should evapotranspire roughly as much vapour as the sea surface, so where is the climatic coastline, on the true sea front or at the back of swamps where extensive? Of course coastal development, and conversion to oil palm down the coast, wil laffect this. But, if the climatic coastline is at the back of the swamp, that might explain why swamps flower at different times from inland forests.



And Joe (it is always good to hear from you!), what has happened to what was left of Andulau, by far the most important forest for conservation from a tree species endemism perspective (and probably a lot more, such as soil fauna and flora, and arthropods, besides)?



Peter

Peter,  Vast expanses of the S. albida swamp which you had  earlier visited have all disappeared giving place to highways and low cost housing. Whether there is regeneration at all in the remaining tall alan stands needs to be investigated.

I will take a better look in these peat swamps. Last time was actually my first visit to a peat swamp ever. We stopped along the water pipeline road and only went in about a hundred meters..... I noticed that there were no small trees because I wanted to take some pictures of the Shorea, so in the end I just collected some fallen leaves and flowers and took some pictures....

THe drought this year was as serious in Brunei as elsewhere  in Malesia.
It broke in Singapore with heavy rain on 16th March, but by then I was no longer ion Brunei so can't say what has happened there.
The Belait river and its tributary Ingei were near record low level
But in the Ingei Protection forest area, the kerapa-swamp forest remained damp underfoot

Dear Ferry, mark, Gathorne and Kit!

Mass flowering of Shorea albida occasionally does coincide with mass flowering in the upland forest, but is much less frequent, as you say, and on occasion does not coincide. I read here (in European news) that fires are raging again in Sumatra: Is there evidence of drought in Brunei, and are there any other dipterocarps flowering?

The regeneration of S. albida is intriguing. Did you go far into the swamp, Ferry? Seedling regeneration and pole sized trees have rarely been observed in the tall alan (seringawan) stands behind the coast (Anderson's phasic community 2), but does occur, patchily, in p.c. 3-4. But I did observe vigorous regeneration on the banks of the fresh drainage cut behind Seria, as it was in 2002. Is it still there? Could it be that increasing eustatic sea level is backing up water in the swamp periphery?

Peter

Ferry,
that's exactly the same for GP--- I recall plotting the dbh class frequency distributions some years ago for our peat Shorea, and amazingly, they formed cohorts with spaced dbh peaks 10-15 cm apart... I was shocked as this indicated recruitment might be what--- every 30, 40 years, given the expected slow growth rates?
fascinating... Mark

For what I heard, this is the first time in a very long time (more than 10 years) that these Shorea's are flowering..... The funny thing is that there are only large trees, I couldn't find a single seedling, sapling or pole..... How is that in the peats of Gunung Palung?

Dear Ferry,
I think not all peat swamps are the same or follow the same pattern.  For at least the period 1983-2000, the common peat  species at Gunung Palung, Shorea uliginosa, never flowered, despite being represented by many very large trees.  Cam Webb or Andy Marshall might have observations since 2000.  Peat at our research site was shallow, a meter deep or so...
Very long masting cycles that vary by species and productivity?
best regards, Mark Leighton

I just went to a peat swamp in Brunei and almost all the Shorea albida were flowering! The whole forest floor was covered with flowers!

Not sure if peat swamps follow a normal Mast pattern though....
