The Wohldorf Forest is the oldest forest district in Hamburg and has been owned by the city of Hamburg since 1437. The forest has always been a popular destination for the Hamburg city population. There have been walking paths here since 1770, and in the first decades of the 20th century the area was accessible by a narrow-gauge railway that has since been dismantled. The Wohldorf Forest covers a total of 364 hectares, of which the central 278 hectares are now a nature reserve and are protected under the Fauna-Flora-Habitat Directive and the EU Bird Protection Directive. The areas not under protection are managed by the Hamburg Forestry Administration, and the nature reserve is jointly managed by the Nature Conservation Office, the Forestry Office and the German Forest Protection Association.

Rodenbeker Quellentag - Gasthaus Quellhof, great place to stop for refreshments with beer garden

The Rodenbek is a river that flows into the Alster in the Rodenbeker Quellental nature reserve. The idyllic Rodenbeker pond along its course is managed by the Rahlstedt sports fishing association from 1934 e.V. and is the habitat of numerous fish species, such as carp, eel and perch. kulturlotse.de/ort/rodenbeker-teich-3806401676914271620

Cheerful birdsong accompanies you through the beautiful deciduous forest. The frogs are croaking in the pond.

The Rodenbeker Quellental nature reserve is an 84-hectare glacial meltwater river system in northeast Hamburg. It lies in the former edge area of the Vistula glaciation. Locally there are elevations in the form of ground moraines. The site elevation is between 15 and 20 meters above mean sea level. The site was granted protected status on January 25, 1977, originally measuring 47 hectares. On July 26, 2011, the Hamburg Senate announced an expansion by 37 hectares to 84 hectares. In the Quellental there are extensive deposits from an ice reservoir, which are now cut through by various smaller basins, small rivers. These are the Rodenbek, the Bredenbek, the Lottbek, the Mühlenbek and other small streams. All flow in an east-west direction to the Alster, a northern tributary of the Elbe. The formation of the Rodenbeker Quellental began in the Weichselian Ice Age, when the Bredenbek Glacier slowly retreated and the meltwater at the base of the glacier found its way to the Alster. The current appearance of the spring valley is also due to spring erosion. (Source: Wikipedia)

The Höltigbaum nature reserve consists of the Höltigbaum, Stellmoorer Tunneltal and Ahrensburger Tunneltal areas. The so-called Hamburger Ring natural area has a total area of 1000 hectares, making it one of the largest nature reserves in the Hanseatic city. The ice masses that covered the area some 15,000 years ago have done their utmost to leave behind a beautiful landscape. In addition to the wide, semi-open pastures, you hike over drumlins - long stretched hills left behind by the ice age - and through tunnel valleys that have formed under the ice masses as a result of the condensation water running off. Over time, humans also influenced the area through agricultural use. Extensive cultivation lasted for many decades. However, because fertilizers and pesticides were not used in the process, today there is a largely unaffected natural area in which rare species have survived. For example, the red-backed shrike feels very comfortable in the Höltigbaum. The brute name belongs to a medium-sized songbird that impales its prey - insects, lizards or even a mouse - on the thorns of a tree. In addition, there are woodlarks and yellowhammers, various amphibian species such as sand lizards or crested newts and two endangered species, polecats and pygmy shrews. On a hike through the nature reserve, you will also come across Galloway cattle, sheep or goats grazing in the wild meadows. The flora was heavily influenced by the military use of the area in the mid-20th century. Again and again, the heavy vehicles destroyed the vegetation cover, so that many pioneer plants settled, which were more resistant to the difficult conditions. The Kratt forests with their many-stemmed oaks and the wild apple and wild pear trees are also striking.

The Wohldorfer Wald impresses with its deciduous trees and is the largest contiguous deciduous forest in Hamburg. The nature reserve has a total size of 278 hectares and forms a 1,800 hectare biotope network in northeast Hamburg with the nature reserves Duvenstedter Brook, Hansdorfer Brook and Ammersbek-Niederung. The Wohldorfer Wald is the oldest forest district in Hamburg and has been designated as a recreation area since 1770. The city acquired the area as early as the 13th century. Due to the proud age of the forest, a special flora and fauna has developed there. The varied tree population is reflected in different forest images. There are alluvial forests, in the depressions and hollows alder and beech forests and also areas with oaks, ash trees and maples. The landscape is shaped by the Ice Age terminal moraines and is accordingly hilly. The animal world of the Wohldorfer Forest includes 14 different bat species and four beetle species from the "jungle relict" category, which only occur in particularly old forests. With a little luck, otters, kingfishers, woodcock or black woodpeckers can also be observed there. https://www.hamburg.de/wandern-ausflug-hamburg/297246/wandern-wohldorfer-wald/

Very nice pond where you can go for a walk.
