Report of the month - January


History: The nature reserve "Schlammwiss" was founded 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 "central ornithologique luxembourg" (COL), a part of the asbl. Natur & Emwelt. Due the fact that Luxembourg doesn't have it own bird ringing central, we're working in cooperation with Belgium. Therefore, Brussel aluminium rings of the Museum of Natural Science are used for the research in Luxembourg.


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 part of the zone Natura 2000. Through the research area flows the river Syr and affects it by periodic flooding.


Research area: Around 30ha is used for researches, on a length of 1km and a width of 30-120m. The main area is covered by reeds and wetlands (20ha). Furthermore, an orchards, a forest a several ponds in the wetland and of the purification plant (SIAS) is used. Mainly, mist nets and rail traps are used for the researches of the breeding population, resting birds and over wintering individuals. There are several projects running in the nature reserve and visitation are possible
