Marco, I agree. Thanks for the offer.

Since there seems to be some momentum in this discussion and it would be
great to keep it moving forward, I went ahead and made a Google Docs
spreadsheet. I sent the link to all on this list (currently 62 active
email addresses). Check your spam filter if you missed it. Since the
archives of the list are public, I think it best to keep the URL of the
data sheet private (i.e., spam-proof), but anyone can add another person
to the list of editors.
I populated it with some data from the earlier Mastwatch database. The
- Date of observation (YYYY-MM-DD, use 1st of month for obs to month
- Area (Peninsular, Borneo, Sumatra, Philippines, Indochina) *
- Location name
- Longitude (d.ddddd) *
- Latitude (d.ddddd) *
- Elevation (m) *
- Forest type (Montane, Hill, Alluvial, Swamp, Kerangas) *
- Real mast event, apparently? (Yes,No) *
- Estimated spatial extent of this reproductive activity (km) *
- Flowering or Fruiting? *
- Percent all trees (> 10 cm DBH) reproductive *
- Percent dipterocarps (> 10 cm DBH) reproductive *
- Estimated months until fruitfall *
- Canopy trees: list reproductive genera (comma-delimited)
- Smaller trees: list reproductive genera (comma-delimited)
- Data owner (person name)
- Data use license (http://creativecommons.org/ prob by-sa or by-nc-sa) *
- Data enterer (person name)
(The fields with * use basic data validation in the spreadsheet to keep
the data formats consistent)
This is just a suggestion for fields. Everyone will have an opinion as to
other fields to add, and in the beginning, feel free to add additional
fields to the spreadsheet, perhaps after a short discussion on this list.
The goal should be to capture key observations without making the list of
fields too long and onerous. Of course, we should really know what
question we are asking first! Please do post short outlines of questions
to be addressed with the data.
A core aspect to agree upon first is what the fundamental data unit is
that we are recording. I suggest that it is an abstract `state of the
forest' at a particular place and time (i.e., not a per tree, or per
species record). This is the thinking behind the DB I uploaded.
Hope this is something we can work with.
