“…The other species from the Northern Hemisphere, S. globifera, is distributed only in the Canary Islands and North Africa. This species can be considered vicariant with S. holoschoenus, as both are found in the same habitat, i.e., Mediterranean tall herb humid grasslands (García-Madrid & al., 2014). In northern Morocco, both species (S. globifera, S. holoschoenus) can coexist in small populations (J.A.…”

Cyperaceae is the third‐largest family of monocotyledons and one of the 10 largest families of angiosperms. The family includes two subfamilies and several tribes, one of which, Cypereae, is the aim of the present study. Recent studies recognize the Ficinia clade, composed of six genera (Dracoscirpoides, Erioscirpus, Ficinia, Hellmuthia, Isolepis, Scirpoides), as more closely related to Cyperus (Cypereae) than to Scirpus (Scirpeae), where it was traditionally placed. In this study, phylogenetic analyses of the Ficinia clade have been carried out, based on sequences of two nrDNA loci (ITS, ETS1f) and three plastid loci (trnL intron, rps16, trnH‐psbA) and with special attention to the smaller genera of the clade (i.e., Dracoscirpoides, Erioscirpus, Hellmuthia, Scirpoides). Results revealed a strong geographic pattern within Scirpoides, in which two groups are identified, one including the southern African and the other representing the northern hemisphere species. Dracoscirpoides and Erioscirpus are monophyletic genera while Hellmuthia formed a clade with Ficinia and Isolepis. One species of Scirpoides (S. dioeca) was outside the clade of Scirpoides s.str. in the analyses, and is here transferred to a new monospecific genus endemic to southern Africa: Afroscirpoides.

“…Other assessment criteria have been proposed: Naturalness (state of conservation of the plant community), Distance in the serial sequence to the potential natural vegetation (PNV), Cover rate (ratio of occupied area to a standard area), Endemicity (exclusivity of the plant community or its upper hierarchical ranks in the area under consideration), Fragility (ecological valence of the plant community), History (relict state of the plant community or of some of its prominent or characteristic species), and Vulnerability (tendency of a reduction in the area of occupancy) (Asensi et al 1991;Dengler et al 2005;Loidi et al 2007;Gauthier et al 2013;Benavent-González et al 2014;García-Madrid et al 2014;Berg et al 2014). Other parameters considered have been: the value of the plant communities in terms of their marginal chorological position (Richard et al 1988), the degree of fragmentationbased on the average distance between geographical occurrences (Seibert 1980;Loidi 1994)-, and the value of environmental services yielded: carbon retention, soil protection or protection of hydrological resources (Loidi 2008;Loidi et al 2007).…”

“…Assessment based on the floristic composition of the community, estimated, for example, as a function of the richness, the importance of the flora involved or the presence of local endemic species (Theurillat et al 1988;Rossi et al 1999;Dengler et al 2005;Sudnik-Wójcikowska et al 2011;Benavent-González et al 2014;García-Madrid et al 2014) has also been tested. Other studies have opted for the assessment of landscapes (Couderc 1980), ecological diversity (Redžić 2007), environmental impact (Richard et al 1988;Ceschin et al 2010) or for the ranking of agroecosystems by diversity of vegetation (Taffetani & Rismondo 2009;Rismondo et al 2011;Galdenzi et al 2012).…”

Risk of extinction of plant communities: Risk and assessment categories

There are many proposals for the assessment of plant communities, based on different criteria, but very few proposals for categorization of the risk of extinction of plant communities (syntaxa). In this paper, concepts related to extent of occurence (EOO), area of occupancy (AOO), extinction and regeneration of plant communities are defined. Also, we propose and define several ranks of extinction risk based on quantitative criteria of the EOO, AOO and processes of decline. The proposals are global, for application to any type of cormophytic vegetation, without geographical restrictions. To check the adequacy of the proposed ranks and its thresholds, the method has been applied to the vegetation of the Iberian Peninsula based on the EOO (122 plant communities) and the AOO (2224 plant communities).

Consider that plant communities associated with Molinio-Holoschoenion class present Maspalomas are those with a higher priority conservation in Spain (García-Madrid et al 2014).…”

Proposal for new EU habitats associated with coastal dune fields of the Macaronesian region. A case study in the Canary Islands (Spain)

The aim of this work is to identify habitats of European interest for the existing dunes in the Canaries, in order to provide data for their proper management. Dune systems considered were the following: aeolian sedimentary systems that cover both most of the island of La Graciosa and also the dune fields of Maspalomas (Gran Canaria) and Corralejo (Fuerteventura). The methodology consisted of overlapping layers of habitats and vegetation by using geographic information systems, so the correspondence between habitat and plant community are analyzed. The results indicate that dune habitats in the Canary Islands have not been well defined. The habitat B2110 embryonic shifting dunes^is associated with several situations incompatible with their biotic and abiotic characteristics. Meanwhile, habitat B2130 fixed dunes with herbaceous vegetation (grey dunes)^is linked, among others, to the phytosociological association Traganetum moquinii. However, embryonic dune formation in the Canaries is mainly done by this community, which is inconsistent with its inclusion in the grey dunes habitat. The proposed habitats of European interest associated with dunes in the Canaries are the following: Coastal shifting dunes with Traganum moquinii, dunes with Tamarix canariensis, Macaronesian aeolian sand sheets and humid dune slacks. It is also suggested the need for a comprehensive study of dune habitats existing in the Canaries and Macaronesia, covering the whole of aeolian sedimentary systems, performing a proper identification, characterization and detailed mapping of these habitats, based on both the existing vegetation and also on the associated landforms and geomorphic processes.
