I was just having a nose around Sweden's tentative list when I stumbled upon this, which took my interest:
The Rise of Systematic Biology In Sweden it is mostly the buildings at Uppsala University associated with Carl Linnaeus that have been put forward it also states that this will be a serial site across 8 countries.
Nomination page:
Since systematic biology is a science based on observations of organisms, a World Heritage Site reflecting the foundation of the science must be defined in areas where descendants still exist of organisms once studied and preserved by scientists. This could be a field collection area or a historical garden.
From what I can pick out it seems these would be in the proposal:
UK:
Chelsea Physic Garden, London (just down the road from my office so this may encourage a visit)
Netherlands:
Botanic Garden of University of LeidenFrance:
Jardin des Plantes, Paris
USA:
Bartram's Garden, Philadelphia
I guess these are the field collections:
South Africa:
Table Mountain National Park/ Cape Floral Kingdom
Japan:
Dejima Island? in Nagasaki and
Hakone National ParkAustralia:
Botany Bay National Park, NSW
It also concludes with the following:
Nomination page:
Apart from the component parts described above, it must here be mentioned that the collected individuals, i.e. the museum specimens, once collected from these populations are of uttermost value to science, especially Linnaeus' natural collection kept in London by the
Linnean Society of London. These can, however, not be included in this nomination.
I don't know whether this is a viable proposal or not, but it seems to have a little more scope than the Darwin based proposal that the UK has been unsuccessful with.
To my knowledge none of the other sites feature on respective tentative lists (Cape Floral Region is already a WHS though). I haven't heard anything about Chelsea Physic Garden during the recent updating of the UK tentative list, and likewise Batram's Garden may have missed the boat with the recent update of the US tentative list.
Not really sure if there was any point in this posting, but it just interested me and I thought perhaps some others may like it as well.
