Once there was a large fen, which today is evidence of the fossil peat soils that are still present. In earlier centuries the moor was largely drained and moist meadows and pastures were created. In the 1990s, the Hienerwiesen were mostly grazed with sheep. In the meantime, a herd of suckler cows grazes in some areas. Most of the areas are mowed - but late to give orchids and other rare plants a chance to sow. Various small bodies of water with a view of the tree frog in need of protection have also been created.
The Hienerwiesen are the largest nature conservation project that the Marburg-Biedenkopf district is implementing on its own. He cooperates with the Lower Nature Conservation Authority (UNB), the nature conservation associations as owners of parts of the Hienerswiesen, with the Ökoagentur Hessen (HGL), which is developing the "Kleewiese" as a compensation area for various interventions, and with some farmers who use the Hienerswiesen Carry out according to the technical specifications of a botanist commissioned by the district.
