MONITORING WETLANDS ALONG THE ‘WESTERN-GREEK BIRD MIGRATION ROUTE’

p. 2
Population of long-distance
migratory birds is declining
worldwide
An important cause is the loss of
suitable stopover-sites during
migration
FACTS
[Berthold, 2001; Birdlife International; Marchant et al., 1990; Çagan et al., 2004; Sanderson et al., 2006; Robbins et al., 1989; Fletcher, 2003]

mainland during their migration’

Wetlands as stopover habitats
‘Areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh,
brackish or salt, including areas of marine waters, the depth of which at low tide does not exceed six meters.’ [Ramsar Convention, 1971]
Convention on Wetlands
of International
Importance,
especially as Waterfowl
Habitat
Logarou Lagoon, April 2007
2/3rd of the Greek wetland area has been drained (20th century)
Further degradation needs to be prevented
Hypothesis and objectivesIntroduction
Hypothesis and objectivesMaterials and methods
ResultsConclusions
Future
Loss and/or deterioration of wetlands along the ‘Western-
Greek Migration Route’ can result in a critical lack of suitable
stopover sites for migrating birds
HYPOTHESIS
Obj. 1 Screening legal instruments and their implementation in the Greek legislation (literature study)
Obj. 2 Screening wetlands along the ‘Western-Greek Migration Route’
p. 9
Obj. 1 Screening legal instruments and their implementation in the Greek legislation (liturature study, in parallel with Bazigou)
p. 10
Conclusions
Legislation to protect migrating birds and wetlands along the ‘Western-Greek Migration Route’ is not sufficient and the one existing is not implemented [Bazigou, 2007].
No control to prevent ecological change from occuring in wetlands
