Abstract

[en] Riparian zones are environments exceptionally rich in biodiversity but are also among the most threatened ecosystems. With the increase in population pressure, humans are currently causing major disruptions to these environments, which will increase further with climate change. As a result, image-based tools have become essential to characterize these sensitive areas on a large scale, with the aim of promoting biodiversity conservation policies. Copernicus data, available at European level, aim to meet these challenges. In this study, the potential of the Copernicus data was compared with two other very high resolution data sets to determine whether they can assess the ecological integrity of riparian zones using a landscape metric approach. The results showed that the Copernicus data react positively to the influence of an anthropogenic disturbance gradient. However, Copernicus data are not shown as accurate as very high resolution datasets, which can have consequences on the management of these environments. The influence of spatial scale on the structure of riparian vegetation was studied and showed that vegetation near the watercourse is the most affected. This work has also shown the relevance of using the landscape approach but has pointed out a limitation in that this approach has not taken into account the three-dimensional variables, which are essential to characterize riparian environments.
