I wasn't suggesting that we limit ourselves to T List alone - merely that we should check the list before looking for other sites. PNG particularly demonstrates this!
Re the Island of Irian Jaya/PNG
Indonesia already has a fine Natural site at Lorentz NP which encapsulates a lot of the Island's specialisms as it covers an altitude range of sea level to almost 5000mtrs. The UNESCO site states that it is in "SE ASia" which of course geographically it is NOT - the Island of Papua is clearly Australasian! http://whc.unesco.org/en/list/955
Then PNG has a T List of 8 which need to be looked at - 1 of them already covers a "Trans boundary Area" - the Trans-Fly (but isn't actually proposed as such - PNG/Indonesia do NOT get on - hardly surprising as Indonesia "stole" the western side of the island!!) The problem for us is whether they add a great deal to Lorentz within our 50. I am sure some of them justify inscription but is there a major gap here?
One is a purely cultural site - among the earliest "Agricultural" sites in the world at Kuk - this was the site I was talking to the Museum curator about.
ALL the other sites are mixed - in order to bring in the tribal aspects of the inidigenous people.
One of these is the slightly controversial WWII Kokoda Track site. Although Many PNG people fought and died (or were just killed by the Japanese) in WWII there is a feeling that this is really an Australian proposal - and indeed OZ is paying money to promote it.
Another is a probably very fine Marine site - but there are good representations of these on the list already and I don't think we want them in our "Top 50 missed"
The "Natural" sight for which the whole island is most famous is the Bird of Paradise. There are many different species of these and their habitat is EXTREMELY specialised - a few hundered meters difference in altitude and you get a different species. All of the sites are likely to contain some appropriate habitat (and Lorentz has some too) but the T List site of Kikori River basin/Gt Papuan Plateau would be best for them.
If I just had to choose ONE site from PNG to encapsulate it I would choose the T List "Middle and Upper Sepik" - it has a fine range of flora and fauna (but being lowland it doesn't have a particularly large number of BofP) but it does cover the tribes of that area whose art and tribal practices ("Haus Tamburan") are very "PNG". This is likely to be proposed on EIGHT different criteria (though IUCN/ICOMOS are likely to remove a couple). I think on reflection it SHOULD be included in our "top 50 missing".
