USE OF ARBUSCULAR MYCORRHIZAL FUNGI IN LAND SCAPE RESTORATION

A short description of the NBS project

The reintroduction of lost ground microorganisms is a strategy strongly recognized as effective to promote the restoration of vegetation cover. Arbuscular mycorrhizal fungi (MA) represent an important component which is commonly lost as a direct result of the activities of roads and railways constructions. The main objective was the implementation of a more efficient soil erosion corrective revegetation measure in construction sites. The mycorrhizae fungi is specially recommended in degraded or poor grounds, or in those areas with restrictive weather conditions: aridity, salinity, scarce or torrential rains. Firstly, mycorrhizaes favour plants rooting. Secondly the ground retention prevents landslides and in third place the mycorrhizae favour the continuity of the establishment of the vegetative cover with minimum contributions or no additional fertilizer and water.

Stakeholder and Governance
Who Started this initiative? A private stakeholder
Contracting Authority Public works Ministry
Project manager (leader and main partners): entities names, and know-how involved Leader: Acciona Construcción (civil engineering works) Main partners: Acciona I+d+i: Technology & innovation division & ADIF: manager of the cut slope plots for the tests
Who (else) was involved in the project ? (Inhabitants, local association, etc.) Acciona Construcción: project manager ADIF: Owners, co-owners of railway infrastructure Public works Ministry : Client
More detail on the process and the role of the different stakeholders (How did it happen?) The ADIF (High-speed railway lines manager company in Spain), in charge of managing a large part of the investment in rail infrastructures and of managing the high-speed network entrusted to its organisation, they offered their work sites to analyse the fuctionality of mycorrhizae amendments in slopes.
OPTIONAL Considering the actual impacts, who are the primary beneficiaries of the project. Construction companies Owners of civil infrastructures City Halls and in general all the citizens
