Report of the month - August

 

History: The nature reserve "Schlammwiss" was founded in 1982 by the foundation"Hellef fir Natur" (HFN). Afterwards the group "Letzeburger Natur- a Vullenschutzliga" (LNVL) founded the station "Schlammwiss". The station is leaded by the "centrale ornithologique Luxembourg" (COL), a part of the asbl. Natur & Emwelt. Due to the fact that Luxembourg doesn't have its own bird ringing central, we work in cooperation with Royal Belgian Instutitute of Natural Sciences. Therefore, we use rings from the Belgian Museum of Natural Sciences.

 

Location: The bird ringing station "Schlammwiss" is located in Luxembourg, between the communities Schuttrange & Munsbach. The nature reserve is part of the 375ha big Syrvalley and is an extremely important Natura 2000 zone. The reserve is periodicly flooded due to the Syr river, which is an important generator of biodiversity.

 

Research area: Around 30ha are used for researche, on a length of 1km and a width of 30-120m. The main area is covered by reeds and wetlands (20ha). Furthermore, the resarch area is subdivided and caracterized by an orchard, a forest, several ponds distributed throughout the reedbed and a purification plant (SIAS). The main techniques employed are mist nets and rail traps in order to realize population estimates (i.e. breeding population, migration, overwintering population) and survival estimates by Capture-Mark-Recapture. There are several projects running in the nature reserve and visitation are possible.
