Über dieses Buch

Since the 1970s and particularly the works of Tüxen (1978) and Géhu & Rivas-Martínez (1981), dynamico-catenal phytosociology has facilitated the integration of vegetation dynamics by more precisely describing the trajectories of vegetation series. A national habitat mapping program (CarHAB), launched by France’s Ministry of Ecology, aims to map the vegetation and vegetation series of metropolitan France at a scale of 1: 25,000 by 2025. In this context, Corsica has been selected as a pilot region, due to its unique characteristics regarding Mediterranean and alticole vegetation.

This book describes in detail the vegetation series and geoseries (ecology, structure, dynamic trajectories, effects of anthropogenic factors on vegetation dynamics, catenal positioning in the landscape) of two Corsican sectors: Cap Corse and Biguglia pond. These two study sites were selected using two methods:

• For Cap Corse, the typology and mapping are based on an inductive approach, which seeks to understand the dynamics of vegetation by drawing on the mature, substitutional, pioneering and anthropogenic associations likely to exist within a tessellar envelope. These various dynamic stages characterize “the vegetation series” (sigmetum or synassociation), the fundamental unit of symphytosociology (Géhu 2006; Biondi 2011). The aim of symphytosociology is, therefore, to define the vegetation series; in other words, it seeks to identify the repetitive combinations of syntaxa under homogeneous ecological conditions.

• For Biguglia pond, the typology and mapping are based on a deductive approach, which combines (under SIG) the ecological descriptor maps with the vegetation mapping, in order to reveal the tesselas and the natural potential vegetation that underlies them. Thanks to the improvement of GIS techniques, this approach has been frequently used to characterize plant landscapes from vegetation to vegetation geoseries since the 2000s, with applications to the conservation management of natural and semi-natural environments.

General Introduction

Abstract

Numerous vegetation and habitat mapping studies have been developed since the twentieth century (Rey 2009; Pedrotti 2013). Vegetation mapping of France, carried out in 1945 by Gaussen et al., by Paul Ozenda in the Alps (Ozenda 1963, 1985, 1986 Ozenda and Wagner 1975) and plant mapping in Montpellier under the direction of Louis Emberger (1961; Emberger and Gounot 1963), demonstrate amply the interest in mapping work for vegetation monitoring and conservation, land-use planning and nature protection.

Vegetation and Vegetation Series of Cap Corse (With Mapping at 1:25,000)

Abstract

Cap Corse is a micro-region encompassing three watersheds: Luri stream, Poggiolo stream and western Cap Corse (Fig. 1). Located in northern Corsica, Cap Corse extends over 33,730 ha, from Mucchiete in the east to the Campu Maggiore stream in the west, to Barcaggio in the north. Cap Corse extends over 23 communes and culminates at 1307 m (Monte Stello). The altitudinal range and the geomorphological complex (Castelnau 1920; Palmieri 2004) of its coastal features induce ecological and phytocoenotic diversity. Beyond its floristic-phytosociological originality, the plant landscape of Cap Corse integrates the ancient and recent history of the Corsican pastoral society (Ravel 1911; Simi 1964; Ravis-Giordani 1983).

Typology and Mapping of Plant Landscape of Biguglia Pond: Application to Planning and Conservation Management

Abstract

The Biguglia Pond shows a great diversity of natural habitats and a strong plant originality (Gamisans 2005, 2006; Géhu and Biondi 1994) and constitutes an ecotone between the marine system and the terrestrial systems.

Discussion

Abstract

Vegetation mapping is a useful tool for the spatialization of vegetation. It provides a large amount of information on the phytochemical diversity of a given territory but requires a consistent scientific knowledge. Compared to vegetation series maps, vegetation maps provide precision on the surfaces and spatial forms of the dynamic stages of the series.

Conclusion

Abstract

The Nature Reserve of Biguglia Pond offers a unique landscape combining systemic diversity: lagoon system, sandy coastal system and salt meadows, mesophilous system and marshy edaphohygrophilous system. These systems are composed of different vegetations and habitats with limited geographical area in Corsica. Despite a strong degradation of vegetation by fire and grazing, the reading of vegetation sequences remains legible and there are still complete sequences from the littoral to the inland. It is a complex and very diverse site where aquatic vegetation overlaps and is closely intertwined with riparian vegetation.

General Conclusion

Abstract

Mapping is a means of expression offering many resources, on various themes (vegetation, vegetation series and vegetation geoseries). It is also an original method of research by the simultaneous representation of qualitative and quantitative variables (Rey 1961; Dupias et al. 1965; Ozenda 1986). The principles of cartography require a multiplicity of techniques for structuring and hierarchizing spatial data, organizing legend and semiology in order to accurately transcribe the phenomena observed in the plant landscape (Pesaresi et al. 2007; Blasi 2010; Penas and Del Río 2012).
