Knowledge of Dipterocarpaceae  

Wow, I'm not even sure how to say that word. Have we recently crossed paths editing somewhere?   WikHead  

To be quite honest, I don't really know a lot about trees. I am however searching for a good central tree-related talk-page for you... somewhere where you might have a better chance of attracting other users with the knowledge you seek. If I can find a good link, I will most certainly post it here to your talk page. )   WikHead  

You're most certainly welcome! I'm guessing that the talk-page at Wikipedia talk:WikiProject Forestry might be a really good place to find other users who can be of most help to you. I wish you the very best of luck with your updates. Have yourself a great day Curritocurrito, and happy editing! )   WikHead  

Hi Curritocurrito, thanks for your post at WikiProject Forestry. If you could elaborate a little more either there or at Talk:Dipterocarpaceae about what specific additions you might suggest for that article, that would be helpful. Thanks,   
Thanks for your reply. I suggest that you add your questions  "why are they important? what habitat are they living? what animals eat their seeds? are they important economically? what minerals or grounds they need?"  to the Talk:Dipterocarpaceae page. That will help others think about how they might contribute to that article.   
I don't get much time to edit Wikipedia pages, but am slowly trying to creat stubs for all the Dipterocarps and correct errors in existing stubs/article. If anyone is interested in editing these pages and needs access to primary sources - I have a reasonable collection of papers (mainly for SE Asia) and can send pdfs.
RE: the questions raised above
are they important economically? - they use to be the main timber export from SE Asia. I don't have figures for what % of the timber trade they account for now
what minerals or grounds they need?- variable - there is a high degree of habitat speacilsation. Some species only occur in Peatswamps, other in poor sand soils i.e. heath forests, others on rich clay soils.
what animals eat their seeds? - when they fruit, which varies from yearly in some of the Sri Lankan species to onces every x (2-16) years in some of the Borneo species - they are an important food source.
