Definitions: • Migration: “the act of moving from one spatial unit to another“
(Baker 1978, p. 23) • ‘true migration’ : “seasonal movement with return to starting point –
the traveller needs a return ticket”(Dingle 1996) • Political definition: the entire population or any geographically
separate part of the population of any species or lower taxon of wild animals, a significant proportion of whose members cyclically and predictably cross one or more national jurisdictional boundaries“ (CMS 1979, Article 1)
• GROMS: true migration > 100 km (excl. local migrants)
CMS
Global Register of Migratory Species (GROMS)http://www.groms.de
A Geo-Database of migratory species at a global scale

Main results
• Identification of migratory species: bats, terrestrial mammals, seals, sirenia, whales and dolphins, birds, turtles, fishes
• Threat assessment (IUCN Red List 2000): species not listed by CMS, but threatened!
• GIS „calculation“ of range states
• GIS analysis of global migrant diversity

PerspectivesAny information system dealing with migratory species has to cover:
- movements of migrants, requiring a GIS with time-code,
- a higher taxonomic resolution at subspecies and/or population level.
At present, none of the major databases covers these aspects.
GROMS is unique because it has developed a data model covering these aspects.
It can be used for any biodiversity information system dealing with species distributions changing overn time
