Link to the decision
Srebarna Biosphere Reserve (Bulgaria)
The Committee was concerned to note that the water quality and balance in this small World Heritage site (600 ha) has deteriorated to such an extent that the site is no longer ecologically viable; large colonies of water birds, except for the Dalmation Pelican, are absent, and many of the passerine species have emigrated or occur only in low numbers. The Committee recognized that most problems were attributable to the slow drying of the lake bed, exacerbated by upstream development projects, impacts of nearby pig farms and a rise in the wild boar population. The Committee, while awaiting the results of a joint Ramsar/World Heritage field mission to assess whether the site still meets criterion (iv), recommended that the Secretariat request the Bulgarian Ministry of Environment to nominate this site to the List of World Heritage in Danger.

Inscription on the Danger ListYear: 1992 -2003
Threats to the Site:
A series of upstream interferences, including the Iron Gates Dam, have permanently altered the natural hydrology of the Danube River in the region and that of Srebarna, located downstream along the river.
Prevention of seasonal flooding has caused significant decline in the size and productivity of Srebarna; agricultural and residential use of surrounding areas have impacted the wetland leading to decline or disappearance of the water and passerine bird populations.
The threats indicated are listed in alphabetical order; their order does not constitute a classification according to the importance of their impact on the property.
Furthermore, they are presented irrespective of the type of threat faced by the property, i.e. with specific and proven imminent danger (“ascertained danger”) or with threats which could have deleterious effects on the property’s Outstanding Universal Value (“potential danger”).
