Moreover, the German Unity 17 transport project, if implemented, would cause a further drop in the water level, posing an additional threat to the pike's habitat.

The LSG serves as an important inner-city link in the Havel biotope network and functions as a flight path for bats and a migration route for the native beaver.

The western boundary runs southwest between an allotment/weekend settlement and a forest and meadow area, then continues along the Faulen See Lake, and finally crosses the Kleiner Jürgengraben ditch.

In the lowland area south of the village of Tiefwerder, the boundary turns west and runs along the Kleiner Jürgengraben for a short distance to the Havel River.

Along the river and the Havelseenweg, the western border stretches south almost to the Freybrücke (Frey bridge) and, after a short detour, it reaches the Heerstraße on Pichelswerder.

Here, it also runs parallel to the district border with Charlottenburg-Wilmersdorf, which is marked by the S-Bahn embankment of the Spandauer Vorortbahn (Spandau Suburban Railway), located a few meters away from the Havelchaussee.

Just before reaching the Stößensee Lake, the LSG border crosses the Hohlen Weg to the west towards the Steffenhorn and runs below the Schulzenwall and Langer Wall along the Hauptgraben back to the north.

The landscape conservation area measures approximately 1.6 kilometers in length from north to south and about 900 meters in width, from west to east.

On the eastern side, separated by the Havelchaussee and the S-Bahn embankment, lies the Schanzenwald forest, which also belongs to the valley sand area of the Spree lowlands.

Interestingly, the Tiefwerder Wiesen and the Schanzenwald forest run parallel to each other, separated by only a few meters, but are now divided by the S-Bahn embankment of the Spandauer Vorortbahn, also known as Olympic Railway.

This railroad was built during preparations for the Summer Olympics, which were canceled due to the First World War, and eventually took place in Berlin 20 years later.

The channel continues to flow towards Scharfen Lanke and Grimnitzsee, which are located on the opposite side of the Havel, facing the Tiefwerder Wiesen.

The biotope and landscape function of the Tiefwerder Wiesen also referred to as pike spawning meadows, relies heavily on their flood dynamics, which are greatly influenced by the water level of the Havel River and human activities.

Additionally, the deteriorating flood dynamics have resulted in limited accessibility of the small remaining area for pike, making it possible only during specific years.

According to an interim report from the Berlin House of Representatives in February 2009, the transport project could lead to a drop in water levels, resulting in changes to the flooding dynamics of the Tiefwerder Wiesen.

[13][14] In response, the state of Berlin aims to protect the Tiefwerder Wiesen by implementing compensatory measures, including artificial irrigation using water from the Havel and the construction of fish ladders.

In order to keep the water in the wetland for as long as possible, a near-natural bottom ramp should be created in the drainage area towards the Jürgengraben, which can also be passed by fish.

[6][16] The Tiefwerder-Wiesen biotope provides a diverse habitat for fish, amphibians, reptiles, insects, birds, and mammals such as bats and the beaver, which has now become a permanent resident after several guest visits.

Similarly, the protected turbot, under Annex II of the Fauna-Flora-Habitat (FFH) (Habitats Directive), searches for food only at night and burrows into the bottom during the day, with only its head and tail protruding.

Another species of concern, the asp, a member of the carp family, gather in small schools as juveniles but develops into solitary fish as adults.

[17] The otter, occasionally spotted in the Tiefwerder Wiesen, finds its ideal habitat in the shallow, fish-rich Havelaltarms and the flood plains.

[6] However, the abundant presence of wild boars has become a concern, with the Senate Department for Urban Development citing their burrowing activity as a contributing factor to the decline of the tall sedge meadows.

For the planned designation of the landscape conservation area as a nature reserve, the state of Berlin conducted investigations on the bat fauna in the Tiefwerder Wiesen and Pichelswerder in 2007.

These nocturnal and highly social bats seek out the insect-rich Tiefwerder Wiesen for hunting, starting from their roosts in places like the Citadel or the old walls on Pfaueninsel.

The silt weevil (Pelenomus velaris), which prefers vegetation-free, periodically flooded, waterlogged sand and mud areas, and its developing plant is not known.

[18][23] The reedbeds of the Tiefwerder Wiesen are home to the grass frog, which is specially protected under the BNatSchG, but since a good population trend was noted as early as 1991, it is no longer classified as endangered on the current Berlin Red List of 2003.

A plank footbridge about 200 meters long, built in 1996, leads through the wet meadows, while wooden bridges guide over several ditches and the Totes Mantel.

In 2004, the Senate Department for Urban Development proposed an elevated path on the edge of the Teltownord as part of a plan for the western region of Berlin.

This path would create an almost continuous green corridor, starting from the Tiefwerder Wiesen, passing via Charlottenburg Palace and the Großer Tiergarten to the western part of the city.

Within this extensive biotope network, the centrally located Tiefwerder Wiesen plays a crucial role as an inner-city link and acts as a " stepping stone for crossing the urban area" for many species.
