The ecological compensation areas in Freiham South include the cultivated landscape around the Freiham estate and habitats on lean, dry sites up to the areas along the railroad.
Colorful flowering meadows with marguerite and sage, orchards and hedges with sloes, wild roses and peacock trees are habitats for birds, small animals and insects. In addition to the Freihamer Allee, which characterizes the landscape, sparse groves of oaks, pines and maples frame the meadows.
The so-called networking axis connects the former railroad depot with the habitats along the railroad tracks. Together with the areas next to the geothermal plant, these sites primarily serve to protect species: for example, the sand lizard, the wasteland shrike and the Idas blue butterfly live here. Species-rich rough grasslands and raw soil areas, shrubberies and bushes form a varied mosaic.
These valuable structures are kept open through controlled maintenance.
