[Mastwatch] Casual observations at Danum Valley

I would like to inform mast around Borneo Rainforest Lodge (BRL) in
Danum Valley Conservation Area, Sabah Malaysia.
Last year, we had a huge mast fruiting (more than 70% of trees had
fruiting, included Dipterocarpaceae and other families, e.g. Durio).
In this year, fruiting is few compared with annual fruiting.
However, I heard from my co-reseaher (Tomoyuki TAJIMA) who is in BRL
now, that he observed a few flowering just now.
He will go back to Sepilok at the end of this month.
Then he will tell more information to Colin and me.
We have continue monthly fall fruit census still now as same as the

ecology of Bornean orangutans (<I>Pongo pygmaeus morio</I>) in Danum
Valley, Sabah, Malaysia: a 3-year record including two mast fruitings.
