Abstract

The aim of the present study was to examine to what extend the Greek Endemic Plants (GEP) are conserved ex situ in botanic gardens (BG) and/or seed banks (SB) in Greece, in Europe and globally. In absence of an official catalogue of GEP and due to inconsistencies in related papers published so far, we had to produce the catalogue of GEP ourselves (it includes 1,429 taxa). We searched electronically in the databases of BGCI and ENSCONET for the ex situ conservation of GEP in BG and SB, respectively. A case-by-case procedure was followed in order to assess their ex situ conservation and queries were made using all their alternative names. All cases with exact match of scientific names were considered as “exact match results” whereas cases with partial match of scientific names were regarded as “partial match results”. Additional data on the ex situ conservation of GEP in Greece were provided by the Balkan Botanic Garden of Kroussia and the J. , A. Diomides Botanic Garden, after personal communication. We found no ex situ conservation for more than half of the GEP (721 taxa). Only 483 taxa (34%) were found under ex situ conservation with certainty; for another 225 taxa (16%), the conservation status is dubious. In total, 439 taxa (31%) are conserved in BG and 345 (24%) in SB; 261 taxa are conserved in both. GEP are ex situ conserved in 213 BG distributed in all continents, except Africa, and in 14 European SB. Only 21% of GEP are conserved ex situ in Greek BG; 11.6% of the GEP may be found in other European BG (mainly of UK, France and Germany), while 8% are present in non-European BG (mainly of USA, Canada and Australia). Only 22% of the GEP are deposited in Greek SB and 3.5% may be found in other European SB, mainly of Germany, Spain and UK. GEP conserved ex situ are mostly represented by only a few accessions (1-5); this holds true for 76.5% of the GEP found in BG worldwide and 85.2% of the GEP found in European SB. The ex situ conservation of GEP in Greece or regionally/globally is far from being effective. Serious efforts should be made in order to achieve Target 8 of the Global Strategy for Plant Conservation.
