4.4 Spatial distribution of species 4.4.1 Species richness Figure 14 shows the geographic distribution of species richness of the sample of CWR assessed (excluding species evaluated as Data Deficient and Not Applicable). As expected, species richness is highest in those areas of the region that are floristically rich – the countries of southwestern and southeastern Europe. The Eastern Mediterranean was recognized as a global Centre of Crop Diversity by Vavilov (1926); therefore, it is not surprising that as indicated in Figure 14, this area has a particularly high concentration of CWR species. Species richness in the countries of the EU (including species evaluated as Data Deficient) is shown in Table 8. The top five countries in terms of species richness are: Greece, Spain, Italy, France and Bulgaria. 4.4.2 Endemic species richness Figure 15 shows the numbers and distribution of the species endemic to Europe (excluding species evaluated as Data Deficient and Not Applicable). Of the sample of CWR assessed, 188 are endemic to Europe (Table 5) and of these, 119 are single country endemics. Endemism is highest in the Spanish territories (37 species), Greece (22), Italy (15) and the Portuguese territories (14). Many of these nationally endemic species occur in the Canary Islands and Balearics (Spain), Sicily (Italy) and Madeira (Portugal). Cyprus is also a hotspot of endemism of CWR species – although only six national endemics were included in this sample, the level of endemism is high taking into account the size of the country. Crimea also exhibits a high degree of endemism which is due to the geographical isolation of the land mass – the main area of diversity being on the south side of the escarpment. As is the case for other wild plant species, mountainous regions are also rich in endemic CWR species – for example, in Greece, Italy and Spain. 4.4.3 Distribution of threatened species Figure 16 shows the distribution of threatened CWR species in the sample assessed. As might be expected, the highest numbers of threatened species are found in the countries of southern and eastern Europe which are known to have comparatively large floras and thus a large number of CWR species. It is notable that many of the Figure 16. Distribution of threatened CWR species in Europe (based on the sample included in the European Red List) 29
