Site Description
The Mareau-aux-Prés islands, along the Loire river, are characterized by a multiple channel pattern, where natural limestone riffles influence the morphology and spatial distribution of vegetated islands, secondary channels and alluvial bars. Within these islands, in september 2012, fluvial management operations (FMO) were launched. The vegetation of the central sandy-gravelly bar (3 ha area) was uprooted and the bar level lowered in order to maintain the flow capacity of the river. A new sandy-gravelly bar appeared in spring 2013, ideal field support for studying long-term ecological issues. A multidisciplinary research program (‘BioMareau’ project) is currently being conducted from 2012 to 2019, focusing on biodiversity recolonization and on interactions and feedbacks between biotic and abiotic compartments.

Purpose
- Understanding colonization dynamics of native and invasive with a focus on the colonization by Populus nigra. - Monitoring of gravel nesting birds in this new bare island. - Understanding the community structure assemblages of ground beetles. - Understanding the consequences of the modification of the feeding habitat of Castor fiber on vegetation composition. - Defining the influence of hydro-morphodynamism on these biotic compartments, through ecological modelling. - Integrating a landscape approach, with the aim to understand the social impacts of FMO.
