[Mastwatch] Shorea albida

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....
