Periodic Reporting for period 1 - ECO-MOUNTAIN (Environmental connectivity as the keystone to ecological restoration of degraded European mountains)
Période du rapport: 2020-09-01 au 2022-08-31
The Pyrenees comprise many fragile ecosystems with a host of plant and animal species, but are subject to severe anthropogenic pressure, exacerbated by extreme weather events, making them vulnerable to hydro-climatological risks. Hotspots of degraded soil exist, but are difficult to locate in a complex and often inaccessible landscape. If not mitigated, pockets of soil erosion can rapidly become a danger to downslope human communities and infrastructure.
ECO-MOUNTAIN aims at developing a novel methodology using the environmental DNA (eDNA) signature of vascular plants in sediments, to identify the origin of eroding soil. In collaboration with local stakeholders, we will test our method on a degraded catchment that is partially undergoing ecological restoration using diverse local plant ecotypes. Results should enable to propose an innovative method for tracing soil erosion and help devise restoration scenarios using local species mixtures.
The project provides evidence that plant eDNA can be used to identify sources of erosion in a watershed. Managers can then focus on restoring the most fragile areas, working with the appropriate land owners.

Identifying degraded ecosystems was done using sediment fingerprinting. It is a relatively new method which allows to identify areas in a catchment where soil erosion occurs following hydro-climatological events. In essence, during intensive rainfall, degraded ecosystems will be subjected to soil erosion and streams draining degraded slopes will transport sediment.
In high mountain catchments, as vegetation type is strongly linked to topography and microclimate, identifying soils originating from below specific plant communities would enhance the sediment fingerprinting method significantly. In that regard, environmental DNA (eDNA) or DNA of organisms isolated from environmental samples has recently been considered as a marker that could be used for sediment fingerprinting.
Expected results (i.e. identified erosion hotspots) will enable stakeholders to guide the implementation of effective mitigation actions, such as nature-based solutions, when restoring these fragile environments.
The impact on the Pyrenean mountain range is tangible though the uptake of research results by stakeholders and spinoff projects. In that regard, the project collaborated with ECO-ALTITUDE (local ecological restoration company), O2H (project on sediment dynamics) and the PLVG (local government, natural resource management). In addition, we will also stimulate the competitiveness of small and medium sized enterprises by developing promising methods for targeted ecological restoration actions for companies such as ECO-ALTITUDE.
