The document analyzes transboundary conservation strategies for migratory species, highlighting the vast number of migratory animals including birds, marine mammals, and fish. It provides definitions of migration and presents a geo-database with extensive data on migratory species, such as the number of species and relevant multilateral agreements for their protection. Efficiency in conservation is assessed through red list data and examples of critically endangered migratory species are discussed.

transboundary conservation
strategies for migratory species.

2. Millions of Animals on the
Move!
• 5 billion passerine birds migrate to wintering grounds in
tropical Africa
• Marine mammals (whales, dolphins, seals) migrate to
marine zones of high productivity for feeding
• nearly 2,000 fish species migrate within oceans or
between fresh- and saltwater (oceanodromous or diadromous)
• the Monarch butterfly is a famous insect migrant

3. Definitions:
• Migration: “the act of moving from one spatial unit to another“ (Baker
1978, p. 23)
• 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)
• ‘true migration’ : “seasonal movement with return to starting point – the
traveller needs a return ticket”(Dingle 1996)
• GROMS: true migration > 100 km (excl. local migrants)

12. Multilateral Agreements affecting
Migrants
• Benelux Convention on the Hunting and Protection of Birds. Brussels, 1970
• Agreement for the Establishment of a Commission for Controlling the
Desert Locust in North-West Africa. Rome, 1970
• Convention on Wetlands of International Importance especially as Waterfowl
Habitat. Ramsar (Iran), 1970
• Convention on International Trade in Endangered Species of Wild Fauna and
Flora. Washington, 1973 (CITES)
•Agreement on Conservation of Polar Bears. Oslo, 1973
•Convention on Conservation of Nature in the South Pacific. Apia, 1976
•Convention on the Conservation of Migratory Species of Wild Animals.
Bonn, 1979 (CMS)

13. Multilateral Agreements especially for
Migrants
• bi- and trilateral agreements such as
Migratory Birds Convention Act, 1994 (USA, Canada); incl
Canada / Mexico / United States Trilateral Committee
• China and Australia Migratory Birds Agreement (CAMBA) and
the Japan and Australia Migratory Birds Agreement (JAMBA)
•Convention on the Conservation of Migratory Species of Wild
Animals. Bonn, 1979 (CMS)
ASCOBANS, EUROBATS, WADDENSEA Seals
+ 7 MoU (eg Great Bustard, African Turtles)

14. How do we measure efficiency of species
conservation?
Catch data: Hunting, Whaling and Fishery
http://www.erin.utoronto.ca/~w3env100y/env/ENV100/hum/cod.htm
From:
The Collapse of the Canadian Cod Fishery , WebCT Courses at University of Toronto
Canadian Cod (Gadus morhua, North Atlantic pop)s Fishery
Red List: VU; CMS: NL

15. Measuring Efficiency using Red List Data
• Global data (population totals per subspecies (mammals) or species (birds):
International Red List: http://www.redlist.org
•Extinct migrants: total of 8 spp
Passenger Pigeon (Ectopistes migratorius),
digitised by GROMS, after Grzimek B (1980) From: Natureworks: Extinct North American Species
