Habitat loss and bird conservation - Delta, SW Holland
| Type of habitat loss: |
Impact on birds |
Reference |
| Effects of a substantial reduction in intertidal area on numbers
and densities of shorebirds. A storm surge barrier and secondary dams were
built in the Oosterschelde estuary (The Netherlands) resulting in a 30%
decrease of intertidal area. |
Total numbers of Oystercatchers in the unaffected parts of
the Oosterschelde did not increase after the loss of feeding grounds in
the Krammer Volkerak. Up to 10,000 Oystercatchers failed to establish themselves
in the remaining intertidal area (also see Lambeck
1991) |

| Changes in abundance, distribution and mortality of wintering
Oystercatchers after habitat loss in the delta area, SW Netherlands. |
Oystercatchers which were displaced from areas which were
lost occurred more frequently on poorer quality areas and
disappeared more often than birds which were not displaced. |
Lambeck 1991 |
| Removal of 170 km2 of intertidal habitat between 1982 and
1987 in the Oosterschelde (SW Netherlands) as a result of large scale coastal
engineering works. |
Open water species remained stable or decreased. Those dependent
on intertidal areas decreased and intertidal bird density decreased slightly.
Those birds displaced by engineering works were not able to settle in the
remaining areas. |
