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)

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

Identification of migratory species:

295 Mammals: 131 bats 42 terrestrial mammals 39 seals and sirenia 83 whales and dolphins

2145 Birds

10 Reptiles ( 7 marine turtles)

1895 Fishes (ray-finned fishes, lampreys, sharks and rays, chimaeras, lobe-finned fishes)

XXL Invertebrates (12 in GROMS, monarch butterfly on CMS App. II)

Perspectives: data sets- Site data (in particular: IBA- congregation areas

BirdLife International)- satellite tracks (for included animation tool)

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
