The right branch of the Weser separates the island of Harriersand from the right bank of the Weser. It is the last right branch of the river through which the Weser water flows continuously and, at least officially, does not have a more sonorous name. This means that the name “Right Sidearm” is entered on the official maps . It branches off from the main stream of the Lower Weser at the Fährplate and joins again at Sandstedt .
Waters
It is 11 to 12 km long and, like the whole of the Lower Weser, lies in the tidal range . The upper half of the river arm is only a few meters wide, the lower half has the character of an estuary and widths of up to half a kilometer. In the estuary area, the island of Harriersand has been lengthened by means of groynes by half a kilometer to the north.
About one kilometer north of the exit from the main stream, a small road bridge crosses the right arm, it is the only car access to Harriersand.
The right arm of the Lower Weser can be navigated with pleasure boats, but the upper part of the fairway is quite narrow at low tide. Sailors have to lower the mast at the road bridge and at a power line not far from it. The area south of the road bridge is used as a sports harbor.
On the right bank of the river arm lies the marshland of the Osterstade , or on more than half of the stretch of water actually two offshore islands, the already mentioned Fährplate , now a peninsula , and the Hammelwarder Sand . Hasseler Balje and Aschwardener Fleet , which border the Hammelwarder Sand, are connected to the right tributary by sluices .
administration
The rights arm of the Weser flows through the municipalities of Schwanewede in Osterholz and Hagen in Bremen in the district of Cuxhaven .

The right branch of the Weser is a former nature reserve . The area with the registration NSG LÜ 110 was around 512 hectares. Of this, around 312 hectares were in the Osterholz district and around 212 hectares in the Cuxhaven district. The former nature reserve was part of the FFH area and the EU bird sanctuary "Unterweser". The area has been under nature protection since May 2, 1985. On February 14, 2019, it opened up in the " Tideweser " nature reserve . Responsible lower nature conservation authorities were the districts of Osterholz and Cuxhaven.
The 11 kilometer long, former nature reserve was bordered by the island bridge between the Weser island Harriersand and Rade in the south and the summer dykes on the Harriersand on the (western) island and the Hammelwarder Sand on the (eastern) mainland side. In the north, the reserve extended to the Sandstedt sailing port.
nature
The island of Harriersand was created by flushing the spaces between originally seven individual islands as part of the Weser correction. The actual fairway is to the west of the island. The tributary east of the island, on the other hand, was able to develop naturally. Extensive tidal reed beds as well as individual tree willows and willow bushes therefore grow on its banks . When the tide is low, tidal flats fall dry. During storm surges, the tributary is influenced by brackish water . In places there are also grasslands delimited by the summer dykes.
Due to the extensive reed areas (a total of around 190 hectares) and in connection with the Strohauser Plate and the Schweiburg , the former nature reserve is one of the most important protection complexes in the Lower Weser area.
Flora and fauna
The flora presents itself as a typical reed and mudflat area with a small variety of plant species: In the reed beds, narrow-leaved cattails and broad-leaved cattails dominate on the water side, water swaths and reed cane on the land side. The marsh marigold is widespread.
In the reed areas breed and. a. Reed warbler , reed bunting , sedge warbler , warbler , bluethroat , bearded tit , marsh harriers and water rails . The bittern , spotted moorhen , Montagu's Harrier and Hen Harrier are the guest birds .
In addition, the area is important as a feeding and sleeping area for swans, geese and ducks who are otherwise in the surrounding areas.
