Viehmoorgraben

BW

The cattle Moorgraben is a creek at the Pape Teicher plateau and in the all- glacial valley with an almost 20 km ² catchment area southwest of the city Gifhorn. The creek flows between Ribbesbüttel and Brennecke bridge in the Allerkanal.

Topography

The creek arises southwest of Vollbüttel in an agricultural area and flows from here to the north of Vollbüttel over. The clarified in a sewage pond effluent from Vollbüttel are introduced into the stream. North of Vollbüttel the creek initially flows through the nature reserve "cattle Moor " Leif earth and then through the forest Fahle Heide before, a few kilometers south-east of Meinersen discharges into the Aller Canal.

Flora and Fauna

In its upper reaches the cattle Moorgraben is due to its history largely straightened and strengthened by agricultural land. It is used here in part as a drainage ditch. In the summer months the water flow in the upper reaches is sometimes very low, which expands in arid times until completely dry traps. In the lower reaches, north of Vollbüttel the stream has been largely due to its location close to nature in the nature reserve.

There are four specialized on only temporarily existing aquatic animal species that are performed on the Red List of Lower Saxony:

• Two different sub-species of caddis fly
• A subspecies of the Long- button water beetle
• As a subset of bladder snails

Water quality

The Lower Saxony Water Quality Report 2004 assesses the chemical water pollution in livestock bog trench almost the entire course as critically polluted (class II -III).
