Mapping the presence of tree species in each Mediterranean-European country is important to estimate conservation priorities at the administrative level. Taxon 66:567–583, WWF (2001) The Mediterranean forests. The woody vegetation is constituted by diverse types of matorrals or shrublands (maquis, garrigue, phrygana) and forests. Our comprehensive analysis of tree taxonomic diversity in the Mediterranean-European region identified 210 tree species or 245 species and subspecies, including 46 endemic trees of the study area. The primary sources of data were the international database Euro + Med PlantBase (http://www.emplantbase.org/home.html), Flora Europaea (Tutin et al. Eleven of these threatened tree taxa, including some very narrow endemic trees such as Abies nebrodensis, Cytisus aeolicus, Rhamnus persicifolia, Zelkova abelicea and Zelkova sicula are only distributed on some large (notably Sicily, Crete, Cyprus and Sardinia) or medium (few Croatian islands sheltering Pinus nigra subsp. These useful plants have been gathered or cultivated since ancient times and some of them (e.g. Plant Syst Evol 162:93–107. mainly the Balkans), have a significantly higher tree taxonomic richness than those located further west or on the large islands. In general, annual rainfalls are greater in the northern than in the southern areas of the Mediterranean Basin and increase with elevation in the mountain ranges. 2009). While the total tree richness is concentrated mainly in the Balkans, endemic trees mostly occurred in the large countries of the three peninsula in western, central and eastern Mediterranean area (Table 2). However, the IUCN Red List contains only a limited number of Mediterranean trees and some old or inadequate assessments should be reviewed again. 2). Darker greens indicate higher richness. Many cultivated and sometime naturalized tree species have not been considered. These data will help to explore the key scientific questions associated to the drivers of the distribution pattern and to the shape of the species-area relationship. Glob Ecol Biogeogr 16:234–245, Thébaud C, Debussche M (1991) Rapid invasion of Fraxinus ornus L. along the Hérault river system in southern France: the importance of seed dispersal by water. 2017), trees constitute a major component of the structure and function of forest ecosystems located in temperate and tropical biomes. Spartium junceum in the Aeolian Islands, Italy) or ecological conditions (e.g. 6, 17 (2019). brutia forests in areas with low rainfall or formerly disturbed by man; (iii) a supra-Mediterranean belt, between ~ 500–1500(1800) m a.s.l., with diverse deciduous oaks forests (including Acer, Carpinus, Ostrya, Quercus and Sorbus) in the more humid ombrotypes; (iv) a mountain-Mediterranean level (~ 1500–2000 m a.s.l.) The countries with the highest tree richness are Greece (146 taxa), Italy (133), Albania (122), Spain (155), Macedonia (116), and Croatia (110). … We followed the classification of the Angiosperm Phylogeny Group for the definition of families (APG III 2009; APG IV 2016). The most abundant birds of this climate are the small ones or simply the birds and birds. This key result shows the importance of the southern part of Europe in preserving this rich biological heritage for a temperate region. (2018) did for instance in the recent Updated checklist of the vascular flora native to Italy; for the only island of Sicily, 11 tree taxa could be included (Betula aetnensis, Fraxinus excelsior subsp. Oxford University Press, Oxford, Browicz K (1982–1996) Chrorology of trees and shrubs in south-West Asia and adjacent regions. Am J Bot 100:951–961, Mazzocchi GB (1969) Trees and shrubs in the Maltese islands. “I?”). We studied the species-area relationship, and evaluated the conservation issues for threatened taxa following IUCN criteria. This checklist represents the first step towards a better understanding of the diversity of trees in the Mediterranean region. The distribution of those native but locally domesticated Mediterranean tree taxa will be discussed in detail below since it represents a crucial issue for the conservation of local genetic resources. country or large island, and by biogeographical provinces. Our definition is slightly different and we define as tree the plants with the following biological features: (i) secondary growth (Fahn 1990); (ii) perennials (they live many years, mostly for decades or centuries); (iii) typically (at least in some environmental conditions or locations) having a single stem or trunk, growing orthotropic with monopodial or more often sympodial branching systems, and bearing lateral branches at some distance from the ground; and (iv) the height of the mature individual is at least three meters. Therefore, the vulnerability of several of these trees is probably underestimated and further assessments are needed in the near future. Finally, there is the group of raptors, these can be both diurnal and nocturnal. Englera 33 (1 & 2): part 1, pp 1–700; part 2, pp 1–878, Svenning J-C, Skov F (2007) Ice age legacies in the geographical distribution of tree species richness in Europe. Among the other DD taxa, at least two characteristic taxa (Platanus orientalis, Vitex agnus-castus) currently experience a severe reduction of their populations due to the artificialization of their habitats, even if they still count a quite large number of populations. The taxonomic richness of the Mediterranean-European region is also found in tree genera, since 86% of the total genera (n = 74) of the whole Mediterranean biogeographic region are present in this European part. What is most worrying is that 84 taxa (19 species and 65 subspecies) included in the checklist are not considered at all in the global IUCN assessment. Among the woody diversity, the definition of a tree per se might be problematic and requires some agreement (e.g. TOTAL TREES: 32 in this pack. Some other locally threatened taxa (Buxus balearica, Rhododendron ponticum) with a highly restricted range in the N. Mediterranean region are not even considered in the IUCN database. Occurrences of each tree taxa were compiled (i) by country (n = 12) and large island (n = 5) (hereafter, “administrative regions”), and (ii) by biogeographical provinces. The species-area relationships show contrasting results between administrative regions and large Mediterranean islands (Fig. Thanks. ), Sicily (Giardina et al. This result underlines the crucial role of trees in the global functioning of the biosphere. http://www.bgci.org/global_tree_search.php?action=about, https://doi.org/10.1080/10549811.2017.1310049, http://www.bgci.org/globaltree_search.php, https://doi.org/10.1371/journal.pbio.1001569, http://www.globalbioclimatics.org/form/maps.htm, https://doi.org/10.1186/s40663-017-0120-0, http://creativecommons.org/licenses/by/4.0/, https://doi.org/10.1186/s40663-019-0170-6. 2017).

(Mulhacén, Sierra Nevada – Spain). Fire and drought are the main drivers underlying this deforestation. A large deforestation period occurred around the 11th century, when the upper forest level was burnt in order to enlarge the surface occupied by subalpine grasslands, resulting in an increase in the erosion rate and in mass movements (Montserrat 1992). It happens also for much less used and unsuspected tree species such as the manna ash (Fraxinus ornus): in Southeastern France, this tree is native in the Maritime Alps but invasive further west, along some rivers of the Hérault department (Thébaud and Debussche 1991). Consequently, the leaves have developed sclerophyllous characteristics in that they are stiff and hard and the stems have thick barks.

In the Mediterranean region, due to millenia-long human impact, we consider that the ecophysiological expression of the tree habit has been often inhibited in most of ecological situations, in parallel with the increase of climate drought. This is not surprising because at the world scale only a tiny percentage (11%) of trees has been assessed by the IUCN Red List criteria, compared with other major species groups (Fauna and Flora International 2013).

Non-Mediterranean climate regions that would feature Mediterranean vegetation include the Nile River Valley in Egypt (extending upstream along the riverbanks), parts of the Eastern Cape in South Africa, southeastern Australia, southeastern Azerbaijan, southeastern Turkey, far northern Iraq, the Mazandaran Province in Iran, Central Italy, parts of the Balkans (including Northern Greece), as well as Northern and Western Jordan. Larger Mediterranean islands (in addition to Malta and Cyprus) corresponding to the Balearic archipelago, Corsica, Sardinia, Sicily and Crete, are treated as independent units to achieve a better spatial resolution of tree taxa and island specificities. Mediterranean vegetation types vary widely with environmental constraints (climate, geology, geomorphology, soil type), dominant plant species, and disturbances induced by man and its herds. We included them in the checklist because in some localities of Corsica, Sardinia and Sicily (Aeolian islands) these taxa meet the above criteria of tree. The biogeographical limits for the Mediterranean region are similar to those proposed by Médail and Quézel (1997), except for some areas of the mountain ridge of the Italian peninsula and of the Balkans. Buxus balearica, Crataegus laciniata, Nerium oleander, Phillyrea angustifolia, Rhododendron ponticum). The highest taxonomic richness in endemic trees occurs in the Italo-Tyrrhenian (n = 16 taxa) and in the Graeco-Aegean (n = 12 taxa) provinces, then in the Betican (n = 9 taxa) and Adriatic (n = 8 taxa) provinces (Fig. J Sustain Forest.

We studied the species-area relationship within the administrative or biogeographical regions by plotting the total native tree taxa richness of each geographic unit as a function of their surface, after log transformation. These taxa belong to 33 different families; the most represented families are Rosaceae (42 taxa), Fagaceae (33 taxa), Pinaceae (21 taxa), Salicaceae (20 taxa), Sapindaceae (19 taxa), Betulaceae (16 taxa), Tamaricaceae (16 taxa), and Cupressaceae (14 taxa).

We compared historical periods of low growth due to low precipitation with the recent period of significant precipitation decline. Abscissa and ordinate axes have a logarithmic scale. Another alternative explanation could be related to better refuge conditions in some situations: unusual big trees or cryptic trees would represent in some Mediterranean areas, notably islands, the remains of old forests in lesser harsh and more stable climates. 2010). Vols 1–10 + supplement. 2012) that are not domesticated but only used by humans, the classical hypothesis of an eastern Mediterranean origin followed by subsequent westward expansion and diversification across the western Mediterranean and Macaronesia is verified. This is particularly the case for Malta and the Balearic Islands. Carob. A biogeographical focus on tree species distribution is needed for conservation of the Mediterranean forests which have undergone rapid changes in structure and composition in recent decades (Mazzoleni et al. Canthium inerme. Among the 245 taxa identified, 19 are considered to be threatened (15 CR + EN + VU) or near threatened (4 NT) by IUCN. Many of the plants are pyrophytes, or fire-loving, adapted or even depending on fire for reproduction, recycling of nutrients, and the removal of dead or senescent vegetation. present before the classical date of the “discovery” of America in 1492) and, apart from culture, are widely naturalized in some parts of the studied area but also native in some areas of the Mediterranean-European region i.e. In: Bulletin de la Société Botanique du Centre-Ouest, Nouvelle Série, Numéro Spécial, vol 39. Botanic Garden and Botanical Museum, Berlin. The ecoregions around the Mediterranean basin and in California have been particularly affected by degradation due to human activity, suffering extensive loss of forests and soil erosion, and many native plants and animals have become extinct or endangered. These cases suggest here a limited influence of historical human-mediated translocations despite the ancient use of these species.

The biome is not limited to the Mediterranean climate zone. Thus, our precise assessment of the expression of the potential arboreal character of the woody species located in the Mediterranean-European region (based on the literature data and on many in situ novel observations) allows us to identify 44 unrecognized real trees, or “cryptic trees”, representing 21% of the total trees occurring in this area (Table 1). Tropical rain forests grow around the equator in South America, Africa, and Southeast Asia. Only 11 genera (Acacia, Amygdalus, Argania, Balanites, Calotropis, Diospyros, Dracaena, Moringa, Prospis, Pterocarya, Ziziphus) are restricted to the southern or eastern parts of the Mediterranean region. 60,065 tree species currently known to science, see Beech et al. 2015) or two cryptic species in the Alnus glutinosa group (Vít et al.
