pbb Carbon and Biodiversity Project

At the Oberammergau and Altenau sites, as well as at Pürschling, Hörnle and Waldalm, individual spruce trees on steep, inaccessible slopes are to be removed using helicopters over an area of approximately 15 hectares. In addition, the massive spread of blackberries is to be prevented and annual mowing carried out. The aim here is to preserve species-rich mountain meadows and prevent the growth of other species. This will also improve the habitat for black grouse, butterflies and many other species.

In Ettal, giant hogweed is being combated over several hundred metres along the Mandlbach stream. An electric lance is used to damage the roots of the plants.

Another measure is the mapping of butterflies on the Sonnenberggrat ridge in the municipality of Unterammergau over a distance of several kilometres. Based on these surveys, various measures and their implications are being planned, depending on the use of the land in grazed, ungrazed and only lightly grazed areas. These will be followed by further measures in subsequent years, which will include the preservation of open land and the transition from forest to open land.

The Fröhner Filz moor in the municipality of Kohlgrub is being rewetted as part of this project by building dams to prevent water from draining away. The first year will be spent planning the project, including analysing the condition of the moor, while the measures will be implemented in the second year. The aim is to raise the water level in the moor.

In Pulvermoos near Unterammergau, a system for regulating the water level is being built on an area of 20-30 hectares. This will allow the water level to be raised throughout the year and lowered once a year for mowing the litter meadow.

In the forests of Oberammergau, willow cuttings will be planted in damaged areas during the first two years, replacing trees that have been destroyed by storms or bark beetles. This will increase biodiversity in the forest and create new sources of nectar for wild bees and butterflies. This measure will be carried out on an area of 15 to 20 hectares.

Along the Ammer, in the catchment area of the Linder, gravel banks that have become overgrown due to a lack of river dynamics are being cleared over several hundred metres.  Shrubs and trees are being removed to create habitat for red-listed species such as the red-winged grasshopper and the gravel bank grasshopper, which depend on large areas of gravel redistribution.
