interesting, given that Parashorea [[Shorea?  no, Parashorea?  No!
Shorea!]] is the one in China, where no GF occurs.  Perhaps the one
recruiting successfully in Sepilok outside of GF is a reinvasion of
Borneo?  There is a clear Indochinese Lithocarpus invader into Borneo.

The dominant Dryobalanops around GP (D. beccarianus? I've forgot) always
seemed gregarious and more frequently fruiting than other dipts but
those are just casual observations.  Their distribution was also patchy
- completely absent from the western side of GP while being abundant
north and to the east.
