We indeed have a large dataset on the Bornean dipts, which you can
probably use. All records have been georeferenced, as part of my
thesis-work. The results are largely available at
Let me know whether you are interested, or possibly want to collaborate?

Apologies for brevity. Hope all is well.
Most important contact of top of head is Niels Raes, whom you may
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
All the best,

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.
