I had been hearing rumors of Shorea flowering and went to confirm these. Indeed, it seems like we are seeing a big flowering in the alluvial forest and adjacent lowlands. I estimate that ca. 80% of the large (>70cm DBH) red and yellow meranti are in flower, some with huge crops (leaves invisible behind a mass of yellow petals).

Also, while there were a few fallen Dipterocarpus sublamellatus flowers, this dominant was generally not flowering. Other rarely flowering taxa that are now in flower or fruit include: Castanopsis, Lophopetalum (x 2 spp), Kokoona, several Baccaurea, Sloanea, Alangium, Durio, Gonystylus, lots of Macaranga with huge crops, Salacia, Dyera, Nephelium, Parkia, Triomma, Sindora. I went to ca. 150 m elevation on the granite-derived soils and did not see any evidence of Shorea or Dipterocarpus fertile up there, so this event seems restricted to the more fertile alluvium and sandstone-derived soils. Perhaps the hill forest will follow? So, not sure how big the fruiting will be, but this is the biggest Shorea flowering I've personally seen. Fruit fall should be sometime in February. Hopefully we get a big seedling flush this time; seedling densities in plots in the granite measured in 2007 lowest they have been since the plots were established in 1993.

I'm currently working on (with David Burslem and Eyen Khoo, John Sugau and Joan Pereira of the Forest Research Centre, Sabah Forestry Department) the conservation assessments of the Dipterocarps in Sabah. The initial focus are the half dozen or so endemic species, but the plan is to expand this to all/most of the Dipts in Sabah. We are using herbarium collection records, data from research plots, forest inventories and my surveys thoughout Sabah as locality data for use in generating ecological niche models for each species - with climate, altitude, soil parent material, soil type etc. being used as the environmental layers. The generated distribution maps are then compared to current forest coverage, satellite images etc. to determine habitat loss (with groundtruthing of both the distribution maps generated by the ENM and current forest coverage images where possible). 1) I am keen on hearing from anyone that has any or knows about other sources of locality data for Dipts in Sabah. 2) I would also be interested in expanding my conservation assessments of the Borneo endemics beyond Sabah. So am keen to hear from anyone that would be interested in collaborating/has locality data for any Borneo endemics from elsewhere in Borneo/that has soil maps/forest cover etc. type data for elsewhere in Borneo.

URL: From: (Peter Shaw Ashton) Date: Tue, 20 Oct 2009 12:11:40 -0400 Subject: [Mastwatch] Flowering in Sabah Status: RO Dear Colin, Shoko - and others? This is all quite fascinating. The data available since c.1958 suggests to me that, in the northern dipterocarp flowering province (i.e. generally February-April but occasionally July-September) there has been a tendency for a light flowering early in each decade and a stronger one late in it. Areas which seem to be mainly in the southern flowering province, such as E. Borneo, seem to have a more mixed track record. For Shoko: There was a student from Osaka City U. some years back who studied flowering phenology of , but never published (I think). (was her name Suzuki?). Her work seemed to indicate some fascinating patterns, which I hope it is not too late for you to check. I remember the following: -Groups of related species do flower in overlapping sequence, , but there is much more confusion because there are so many more species; however: -Species in Shorea sec. Mutica, if separated into two series - of sandy and on clay soils, then conform much more convincingly to the Pasoh pattern. The big exception seemed to be the species related to S. macroptera (with two subspecies, one more on clay, one on sandy soil, S. acuta and S. slootenii (sandy), S. ferruginea (clay) and S. myrionerva (clay, streams), all of which seemed to flower simultaneously beginning. It would also be really interesting to check population samples of these species for fruit with variable but high multiple seeds/seedlings, implying adventive polyembrony, that Awtar Kaur found in S. -The yellow merantis completely ovedrlapped with the reds, but may also have two series, on each soil. The evidence was less clear among them. What other pollinators are you discovering? Cheers?

URL: From: (Peter Shaw Ashton) Date: Tue, 20 Oct 2009 12:11:40 -0400 Subject: [Mastwatch] Flowering in Sabah Status: O Dear Colin, Shoko - and others? This is all quite fascinating. The data available since c.1958 suggests to me that, in the northern dipterocarp flowering province (i.e. generally February-April but occasionally July-September) there has been a tendency for a light flowering early in each decade and a stronger one late in it. Areas which seem to be mainly in the southern flowering province, such as E. Borneo, seem to have a more mixed track record. For Shoko: There was a student from Osaka City U. some years back who studied flowering phenology of , but never published (I think). (was her name Suzuki?). Her work seemed to indicate some fascinating patterns, which I hope it is not too late for you to check. I remember the following: -Groups of related species do flower in overlapping sequence, , but there is much more confusion because there are so many more species; however: -Species in Shorea sec. Mutica, if separated into two series - of sandy and on clay soils, then conform much more convincingly to the Pasoh pattern. The big exception seemed to be the species related to S. macroptera (with two subspecies, one more on clay, one on sandy soil, S. acuta and S. slootenii (sandy), S. ferruginea (clay) and S. myrionerva (clay, streams), all of which seemed to flower simultaneously beginning. It would also be really interesting to check population samples of these species for fruit with variable but high multiple seeds/seedlings, implying adventive polyembrony, that Awtar Kaur found in S. -The yellow merantis completely ovedrlapped with the reds, but may also have two series, on each soil. The evidence was less clear among them. What other pollinators are you discovering? Cheers?

In Sepilok We had a big flowering of Parashoreas (P. malaanonan and P. tomentella) in Sepilok in late May, plus a few trees of Shorea leprosula & S. johorensis and 1 Shorea seminis. We had another small flowering of the Parashorea, plus a few other species Vatica rassak, Dryobalanops lanceolata & Shorea almon in September. And for the tenth year running - I don't think we are going to see any significant recruitment in Sepilok. In other parts: We had a big flowering in parts of the upland MDFs of the Trus Madi FR in early August - with S. parvifolia, S.parvistipulata, S johorensis, S. platyclados, S. ovata, H. montana, H. plagata and P. malaanonan all flowering. We also had a smallish flowering in the upland MDF of Mt Kinabalu in July/August - with S. hopeifolia, Dipterocarpus ochreaus and D. humeratus flowering. There have also been flowerings in the Sungai Imbak, Lingkabau amd Timimbang FR - from what I've seen they aren't huge and it is unlikely there will be any significant natural recruitment. Especially as we are stripping most of the interesting trees (i.e. non-Parashoreas) of their seed crops for restoration work in Sabah.

I had been hearing rumors of Shorea flowering and went to confirm these. Indeed, it seems like we are seeing a big flowering in the alluvial forest and adjacent lowlands. I estimate that ca. 80% of the large (>70cm DBH) red and yellow meranti are in flower, some with huge crops (leaves invisible behind a mass of yellow petals). Species that I noted in flower include: S. parvifolia, pauciflora, johorensis, leprasula, parvistipulata ssp. paristipulata, hopeifolia. Species already with fruit included pinanga, macrophylla (already large), gibbosa. I didn't see any selangan batu or white meranti reproductive. Also, while there were a few fallen Dipterocarpus sublamellatus flowers, this dominant was generally not flowering. Other rarely flowering taxa that are now in flower or fruit include: Castanopsis, Lophopetalum (x 2 spp), Kokoona, several Baccaurea, Sloanea, Alangium, Durio, Gonystylus, lots of Macaranga with huge crops, Salacia, Dyera, Nephelium, Parkia, Triomma, Sindora. I went to ca. 150 m elevation on the granite-derived soils and did not see any evidence of Shorea or Dipterocarpus fertile up there, so this event seems restricted to the more fertile alluvium and sandstone-derived soils. Perhaps the hill forest will follow? So, not sure how big the fruiting will be, but this is the biggest Shorea flowering I've personally seen. Fruit fall should be sometime in February. Hopefully we get a big seedling flush this time; seedling densities in plots in the granite measured in 2007 lowest they have been since the plots were established in 1993. The team who has been collecting with me is now in the forest. Let me know if there is anything you especially would like to see.

Flowering are especially intensive around the canopy crane plot, where flowering is the largest since the establishment of the plot in 2000. Probably 70 % of canopy trees have some flowers/fruits, while it is not so other areas of the park probably. Flowering of Dryobalanops has already finished one month ago, while many Shorea species are still flowering. This year we had minor flowering in June, thus some dipterocarp trees have both flowers and almost mature fruits. We are observing flower visitors, but we see less giant honey bee hives comparing with flowering 1996. I heard that flowering also occurred in the upper Baram, some part of Sabah, and around Kuching. We already enjoy plenty of durians in local markets.

The data available since c.1958 suggests to me that, in the northern dipterocarp flowering province (i.e. generally February-April but occasionally July-September) there has been a tendency for a light flowering early in each decade and a stronger one late in it. Areas which seem to be mainly in the southern flowering province, such as E. Borneo, seem to have a more mixed track record. For Shoko: There was a student from Osaka City U. some years back who studied flowering phenology of , but never published (I think). (was her name Suzuki?). Her work seemed to indicate some fascinating patterns, which I hope it is not too late for you to check. I remember the following: -Groups of related species do flower in overlapping sequence, , but there is much more confusion because there are so many more species; however: -Species in Shorea sec. Mutica, if separated into two series - of sandy and on clay soils, then conform much more convincingly to the Pasoh pattern. The big exception seemed to be the species related to S. macroptera (with two subspecies, one more on clay, one on sandy soil, S. acuta and S. slootenii (sandy), S. ferruginea (clay) and S. myrionerva (clay, streams), all of which seemed to flower simultaneously beginning. It would also be really interesting to check population samples of these species for fruit with variable but high multiple seeds/seedlings, implying adventive polyembrony, that Awtar Kaur found in S. -The yellow merantis completely ovedrlapped with the reds, but may also have two series, on each soil. The evidence was less clear among them. What other pollinators are you discovering? Cheers?

In Sepilok We had a big flowering of Parashoreas (P. malaanonan and P. tomentella) in Sepilok in late May, plus a few trees of Shorea leprosula & S. johorensis and 1 Shorea seminis. We had another small flowering of the Parashorea, plus a few other species Vatica rassak, Dryobalanops lanceolata & Shorea almon in September. And for the tenth year running - I don't think we are going to see any significant recruitment in Sepilok. In other parts: We had a big flowering in parts of the upland MDFs of the Trus Madi FR in early August - with S. parvifolia, S.parvistipulata, S johorensis, S. platyclados, S. ovata, H. montana, H. plagata and P. malaanonan all flowering. We also had a smallish flowering in the upland MDF of Mt Kinabalu in July/August - with S. hopeifolia, Dipterocarpus ochreaus and D. humeratus flowering. There have also been flowerings in the Sungai Imbak, Lingkabau amd Timimbang FR - from what I've seen they aren't huge and it is unlikely there will be any significant natural recruitment. Especially as we are stripping most of the interesting trees (i.e. non-Parashoreas) of their seed crops for restoration work in Sabah.

He's been working on SDM of dipterocarps across Borneo for some time, with an interest in some of the same questions (at a slightly broader spatial scale). All the best, Gary On Mon, Oct 19, :40 AM, Colin Maycock wrote: Hi All, On a non-Mastwatch topic. I'm currently working on (with David Burslem and Eyen Khoo, John Sugau and Joan Pereira of the Forest Research Centre, Sabah Forestry Department) the conservation assessments of the Dipterocarps in Sabah. The initial focus are the half dozen or so endemic species, but the plan is to expand this to all/most of the Dipts in Sabah. We are using herbarium collection records, data from research plots, forest inventories and my surveys thoughout Sabah as locality data for use in generating ecological niche models for each species - with climate, altitude, soil parent material, soil type etc. being used as the environmental layers. The generated distribution maps are then compared to current forest coverage, satellite images etc. to determine habitat loss (with groundtruthing of both the distribution maps generated by the ENM and current forest coverage images where possible). 1) I am keen on hearing from anyone that has any or knows about other sources of locality data for Dipts in Sabah. 2) I would also be interested in expanding my conservation assessments of the Borneo endemics beyond Sabah. So am keen to hear from anyone that would be interested in collaborating/has locality data for any Borneo endemics from elsewhere in Borneo/that has soil maps/forest cover etc. type data for elsewhere in Borneo.
