I recently (12-23 June) travelled in Sabah with Kazuki Miyamoto. Many dipterocarps were fruiting in lowland (c. 200-500 m) mixed dipterocarp forest in Maliau Basin, but we had not time to identify to species. However, we found no trees (including Shorea coriacea) bearing flowers or fruits in montane heath forests (c. 1000 m) in Maliau. In Nabawan (midway between Keningau and Maliau, c. 500 m), neither mixed dipterocarp (including Shorea laevis) or heath forest (inc. Shorea venulosa and Hopea pentanervia) had flowers or fruits. Along the road from Maliau to Nabawan, many individuals of one liana species of Bauhinia were blooming simultaneously (orange flower, entire leaf). I have not noticed this species in the previous visits to Maliau. Graduate student from Kyoto (Yuki Tsujii) said that in two lowland forests on sedimentary and ultramafic soils (c. 600 m) in Kinabalu only Parashorea was fruiting, while Shorea spp. (including S. laevis, S. argentifolia, S. leprosula, S. parvistipulata, S. ?micans) did not, which was confirmed by my visits in August.

He said that the recent mast fruiting at Gunung Palung has been huge; from what he described, I estimate it may have been the biggest successful mast since 1990! It?s been a very long time since we?ve seen dense dipterocarp seedling carpets, but he said there were dipterocarp seeds everywhere, starting to germinate (at the end of July). He most recently visited the forest in the south of the park (Pangkal Tapang area), but had also observed the Cabang Panti Research Station site (central west) several weeks earlier. There, the dominant Dipterocarpus sublamellatus (alluvial) and Shorea quadrinervis (low hills) were in heavy fruit. Overall, almost every dipterocarp tree he saw was in fruit, of almost all the species. Plus all the other masting taxa: Koompassia, Artocarpus, Nephelium, Manigera, Durio, Baccaurea, Scaphium, etc. Great news!

Date: Sat, 23 Aug 2014 07:46:37 +0800 Subject: [Mastwatch] Big Palung Status: O Hi Cam, Do you have rainfall/temp data for that area? In Sepilok only the early flowering species (Parashorea spp., S xathophylla went in a big way with up to 80% of the trees of those species), with most other species down around the 10% mark or less. In the rainfall/temperature data for Sandakan - there isn't a pronounced drought signature, but there is a pronounced reduction in temps - corresponding to the timing of the polar vortex I guess I'm wondering if there is enough data around to do a Borneo-wide assessment of flowering/fruiting intensity - environmental conditions. We have data for about 5500+ Dipts from Sepilok for the 2010 & 2014 GF events.

What a great idea. Let?s ask, ?Who on this list might be able to provide: 1) Their own temp/rainfall records for Jan-Jun 2014, or a commitment to seek out those data from nearby weather stations, 2) Qualitative (descriptive) assessments of flowering/fruiting/recruitment, 3) Quantitative (phenology, seedling plots) assessments of flowering/fruiting/recruitment?? Even a fairly rough study (4-5 sites & descriptive mast data only) would be fun to try. Best, Cam From: (Ashton, Peter) Date: Sat, 23 Aug 2014 16:02:12 +0000 Subject: [Mastwatch] Big Palung Status: O Hi all, My since the seventies is that the real McCoy mast takes place roughly every other time, that is roughly every decade. What has the Sepilok (and Lambir?) experience been in this respect? Both Gng Palung and Sepilok are close to the equator relative to Pasoh, so likely getting the southern, about July, trigger rather than January trigger from time to time, which might screw things up somewhat.

Replicated canopy temperatures are a vital future research priority.

With the wide range of low cost mini data logger/temperature sensors now available (e.g. Thermobuttons, ibuttons, etc.) it would be relatively easy to do. Eyen Khoo (from Forest Research Centre, Sabah Forestry Department) and I still maintain a climbing crew and the 160 ha Dipterocarp plot in Sepilok - so that could be one potential site. I suspect David (Burslem) and Glen Reynolds would also like to include the Danum 50 ha plot. We could also discuss with Prof Kitayama to see if he would want one/some of his Mt Kinabalu sites included. Eyen - this might also be good to do in our areas with the critically endangered dipts (Sianggau for Keruing Jarang, Nalumad for Keruing Renau, Kampung Tambilidon for Shorea kudatensis). The iButtons are a few hundred RM/piece (Temp alone is ~ RM200, Temp and RH ~ RM450).
