40 years - 40 natural reserves – Leresmillen
In 2014, the Hellef fir d'Natur Foundation was able to acquire an important wet meadow bird refuge area near the village of Leresmillen.
The 16.5 km long valley of the "Trëtterbaach" is known among ornithologists for its diverse bird life. In 2014, natur&ëmwelt Fondation Hellef fir d'Natur was able to acquire an important refuge for birds, whose occurrence is typical for extensively used wet meadows, near the village of Léresmillen. These areas reflect the importance of the "Trëtterbaach" and its tributaries, surrounded by small wetlands and marshes and a few lean mowing meadows. In total, the Foundation owns 47.98 ha between the Léresmillen and Emeschbaach areas.
The area around the "Trëtterbaach" is characterized by numerous wet meadows and lean mowing meadows, all of which are considered habitats for numerous endangered bird species. 15 endangered and Europe-wide protected species such as the Black Stork (Ciconia nigra), the Red Kite (Milvus milvus), the Red-backed Shrike (Lanius collurio), the Great Grey Shrike (Lanius excubitor), the Yellow Wagtail (Motacilla flava), the Meadow Pipit (Anthus pratensis) or the Common Snipe (Gallinago gallinago) can be observed here. In 2019, newspapers announced the sad news that the formerly widespread whinchat (Saxicola rubetra) has become extinct as a breeding bird in Luxembourg. One of its last refuges was in the extensive wetland here, where it can still be observed during the migratory season. Threatened butterfly species such as the blue iridescent fire butterfly (Lycaena helle) or the fringe ringed moth (Boloria eunomia) also occur in the wetlands dominated by snakeweed (Bistorta officinalis). The "Trëtterbaach" is home to fish species such as the brown trout (Salmo trutta fario) and the bullhead (Cottus gobio) or the brook lamprey (Lampetra planeri), which benefit from the renaturation measures.
