• Theses
• For a search catalogue on in situ data (cwr and
  on-farm)
• we need multicrop passport descriptors
• Characterisation and evaluation is most often
  done ex situ,
• therefore the linkage from in situ data to ex
  situ data
• and vice versa is important
• The data structure for the exchange of
• ex situ and in situ multicrop passport
  descriptors
• is the same for a large extent.

User needs
For use and conservation of PGR knowledge about
the species and the site is relevant - but data
about the site is often missing

Why does the site matter? - genetic variability
reflects adaptations of germplasm to
environment - abiotic, biotic and anthropogenic
elements of the site influence the pattern of
genetic diversity in space and
time environmental conditions of collecting
sites are of high interest for
- characterization of gene bank material
(retro-classification of accessions) - planning
of new collection missions - conservation
strategies

The Site - a part of the landscape
B. Biodiversity of landscapes
A. Geodiversity of landscapes

• Biodiversity
• Diversity of species
• Diversity of genes

Abiotic factors (Geos)
Lower troposphere

• Biotic factors (Bios)
• Flora
• Fauna

Georelief, soils and substratum

Tools and Infrastructure for GI
- Geographical Information Systems (GIS) -
GeoDataInfrastructure (SDI) can be used - to
improve existing passport data (map
overlay) - as data source while createing
passport data
