known to frequent the coastal shelf off South America
(Nicholls et al. 2002, Spear et al. 2003), making Argentina,
Chile, Peru and Uruguay crucial for their conservation.

Tracking ocean wanderers: the global distribution of albatrosses and petrels – Discussion
Figure 5.16. Regional maps of global utilisation distributions (UD’s) of breeding albatrosses in relation to EEZs. Important breeding sites for
albatrosses in each region are shown. A. North Pacific; B. Australasia; C. Southern Atlantic and Indian Oceans. These composites were created
by calculating the utilisation distributions for each species and combining them giving each species equal weighting.
The geographical designations employed do not imply the expression of any opinion whatsoever on the part of BirdLife International concerning the legal status of any country, territory or area, or
concerning the delimitation of its frontiers or boundaries. At the time of going to press it was noted that the EEZ surrounding South Georgia does not extend as far west as indicated in the map. A dispute
exists between the Governments of Argentina and the United Kingdom of Great Britain and Northern Ireland concerning the sovereignty over the Falkland Islands (Malvinas).

5.3 ESTABLISHMENT, MAINTENANCE AND USE
OF A GIS TRACKING DATABASE
The workshop participants acknowledged the importance
and uniqueness of the integrated perspective of global
Procellariiform distributions achieved at this workshop, and
agreed to maintain the tracking database assembled for the
Important Bird Area (IBA) delineation exercise beyond this
meeting. However, participation in this exercise does not
imply the contribution of the tracking data into a
permanent database, nor does it give BirdLife International
the permission to use the contributed data indefinitely. The
data sets used in this workshop will not be automatically
incorporated into a permanent database at the end of this
exercise. Instead, the workshop participants will be given
the opportunity to re-submit their data sets into a
permanent repository, on the basis of agreed-upon terms of
use to be ratified at a later date. Alternatively, users may
choose to withdraw their data from the tracking database
once the IBA exercise has been completed.
Many important issues concerning data ownership and
the longevity of this database will be determined in future
discussions. Nonetheless, the participants decided to
proceed with the establishment of the Procellariiform
tracking database at this time, acknowledging the need to
