Nature-based solutions to facilitate forest's adaptation to climate change.
The objectives with future climate change in the Ariege Pyrenees Ariegeoises are to maintain the services provided by the forest, whether in terms of economic services (wood production and associated jobs), socio-cultural (wood production and associated jobs), socio-cultural services (landscapes, recreational uses, tourism) or regulation ervices (soil maintenance in mountains, carbon absorption and storage, preservation storage, preservation of water quality).
The actions will be :
- to identify and test nature-based technical solutions
- to facilitate to... more
The ground threshold Heimertingen is currently impassable for aquatic organisms, such as fish or micro-organisms moving on the ground. By converting the concrete sleepers into shallow ramps, the passability for aquatic organisms is achieved. A sole ramp provides passability over the entire width of the watercourse. The watercourse section is extended and creates new valuable habitat.
The aim is to achieve good ecological status or, in the case of heavily modified water bodies, good ecological potential in accordance with the Water Resources Act (§ 27 WHG). The status of the habitat for aquatic organisms is to be improved by relocating... more
Following 2005 floods, the water authority Kempten improved the flood protection at the torrent Argen near the development area Seltmans-Süd (municipality Weitnau). In course of that the river bed was widened, retention area was created and the river bed was redesigned in order to imrove the ecological passability.
The Arlacher Weir is currently impassable for aquatic organisms such as fish or microorganisms moving along the river bed. Due to local conditions, the construction of a ramp is not possible. The passage is therefore made by a fish ladder. It runs along the bank next to the weir and connects the upper and lower water. Different variants, such as a near-natural bypass channel or a technical fish ladder are being investigated. Structural, hydraulic, ecological and economic criteria are compared for the different variants. The measure is part of the project Agile Iller.
The BUND Naturschutz owns some litter meadows in the Wettismoos and maintains them according to the guidelines of nature conservation. The meadows are partly mowed by hand. In order to preserve the biodiversity the mowing takes place after the first of September. The mowed material is used as litter by local farmers.
Strong drainage, intensification of use and abandonment of use have severely degenerated the Felmer Moos. The BUND Naturschutz was able to acquire 12.5 hectares in the Felmer Moos and has renaturalized it according to the requirements of climate and species protection.
With 24 dam power plants, the Lech is the most densely used river in Bavaria. Its original floodplains with their typical flora and fauna have disappeared. Only a few areas, mostly near-natural, have remained, including the Litzauer Schleife south of Schongau. But here, too, natural processes have been disrupted: the construction of the Forggen lake dam has cut off the transport of sand, gravel and boulders (so-called bedload) from the Tyrolean Lech. Strong flood events hardly ever occur anymore due to the strong regulation of the water level. Within the framework of the project, the association Lebensraum Lechtal will carry out measures... more
Forest clearance work to allow the development of the most beautiful trees and to limit the risks linked to the fall of decaying trees and fires.
The two ground threshold in Felheim and the one in Pleß are currently impassable for aquatic organisms, such as fish or micro-organisms moving on the ground. By converting the concrete sleepers into shallow ramps, the passability for aquatic organisms is achieved. A sole ramp provides passability over the entire width of the watercourse. The watercourse section is extended and creates new valuable habitat.

"Gravitational natural hazards such as snow avalanches, rockfalls, shallow landslides and volcanic activity represent a risk to mountain communities around the world. In particular, where documentary records about these processes are rare, decisions on risk management and land-use planning have to be based on a variety of other sources including vegetation, tree-ring data and natural hazard process models."
