hallo,
ich habe etwas gefunden, das ich hier posten möchte. auch wenn es sich eher nach artenschutz anhört, sind die zahlen und fakten erschreckend und solltem jedem, der sich einen molukkenkakadu zulegen will, zu denken geben (die zahlen für whk's sind übrigens ähnlich dramatisch):
=======================================
Justification: This cockatoo qualifies as Vulnerable because, like its congeners, it is a very popular cage-bird and has suffered a rapid population decline as a result of trapping for trade, combined with deforestation in its small range. Moreover, this decline is projected to continue and perhaps accelerate.

Population estimate >10,000
Population trend decreasing (continuing)
Range estimate 18300 km2
Country endemic? Yes
Range & Population:
Cacatua moluccensis is endemic to Seram, Ambon, Saparua and Haruku in South Maluku, Indonesia. There are no recent records from Saparua and Haruku, and it may only survive at one locality on Ambon, leaving almost the entire population on Seram, where it was once abundant, but has suffered declines, including an estimated 20-40% in one region during the 1990s. It remains locally common in Manusela National Park and, perhaps especially, in east Seram.
Ecology:
It is largely resident (although perhaps subject to minor local movements) in lowland rainforest up to 1,000 m. Recent studies estimated that densities of 8.3±5.3 individuals/km2 in primary and secondary forest, declined to 1.9±1.8 individuals/km2 in recently logged forest. Furthermore, highest densities in unlogged forest were encountered below 180 m, clearly illustrating the importance of primary lowland forest.
Threats By the 1980s the species was being extensively and unsustainably trapped for the cage-bird market, with an estimated 74,509 individuals exported from Indonesia between 1981 and 1990, and international imports averaging 9,751 per annum between 1983 and 1988. Although reported international trade fell to zero in the 1990s, trappers remain highly active and birds are openly sold within Indonesia. Forest loss, degradation and fragmentation owing to commercial timber extraction, settlement and hydroelectric projects, poses the other major threat. Most forest has already been lost from Ambon and the coasts and lowlands of Seram. It has also been considered a harmful pest to coconut palms, and, historically at least, was consequently persecuted.
Action:
It has been listed on Appendix I and II of CITES since 1989, a measure that effectively curtailed reported trade at the international level. It occurs in Manusela National Park on Seram, although it is not clear what level of protection this affords. A programme of local awareness, linked with the promotion of ecotourism, has recently been launched.
Targets:
*Conduct detailed research into its population dynamics, local movements and threats.
*Monitor trade and promote effective enforcement of regulations to control it.
*Establish a strict nature reserve in the Wae Fufa valley of north-east Seram, and adjoining catchments.
*Continue and expand conservation awareness campaigns on Seram, using it as a flagship species to reduce trapping pressure and encourage local support.
