The two giant sequoias near Kölpin in the parish of Demen in the district of Ludwigslust-Parchim in the German state of Mecklenburg-Vorpommern, are a natural monument.
[1] They belong to the species commonly known as giant sequoia, but also Wellingtonia and Sierra redwood (Sequoiadendron giganteum).
Hüniken was a member of the Mecklenburg Society of Foresters (Verein Mecklenburgischer Forstwirte).
As a result of his interest in dendrology, rare trees were also planted, such as these giant sequoias, otherwise native in North America on the western slopes of the Sierra Nevada in California.
[5] At the foot of the trees stands a memorial to Heinrich Hagge, who worked in this forest estate from 1875 to 1904.
