This checklist is a review of the Danube Delta National Institute (D.D.N.I) intern reports dealing with the vascular wild flora from Danube Delta Biosphere Reserve (D.D.B.R.) and recent field observations during 2006 – 2010. It summarizes a total number of 1215 taxa, listed per genus rank in alphabetical order. There were excuded from the database the synonymous names of the species, which have been found according to the litterature or species with doubtfull presence and/or insuficient data. Key words: Danube Delta, vascular flora, checklist, conservation status, red and black list INTRODUCTION This changing wetland due to its hydrological regime, human impact and nevertheless climate changes comprise a large variety of plant species, both native and alien. Debates on D.D.B.R. vascular flora are still present and there is not a recent comprehensive list dedicated. Therefore, we have attempted to provide relevant present data on D.D.B.R. wild and subspontaneous vascular plants, necessary for biodiversity inventory, field monitoring, management plan and to support different research projects. The enlisted plants cannot be a complete assemblage of data and we emphasize the importance of expanding and refining the understanding of Danube Delta and its surroundings flora. Comparing it with other lists, the current inventory differs in total area covered and number of species, which is larger, namely the limits of Natura 2000 SCI Danube Delta. This checklist gives, also, information on the accepted scientific names and synonyms from Flora Europaea, an up to date conservation status at national level made by 1994 [12] and 2009 [6] red lists and their general distribution. MATERIALS AND METHODS From the total of 5480 database entries of species have been validated as occurence and nomination according to Flora Europea [28, 29] and other listed references, 1215 vascular plant species. The presentation of the species list is made as it follows: accepted scientific name found into the research reports or database; family of the species; the synonyms mentioned into round brackets; the general distribution and if is alien species with indication (*); occurence in D.D.B.R. and map (Annex I); and the conservation status at national level, if should be the case. Abbreviations used in the list for occurrence: Ca.-Caraorman (including the forest and sand dunes); CARo.C.A.Rosetti; Ch.-Chituc (including Periboina); Cl.-Chilia; Cn.-Cardon (including the forest); Cs.-Crişan; DD.Danube Delta; Do.-Doloşman (including the Iancina Cape); Dr. –Dranov; Du.-Dunăvăţ; Ec.-Erenciuc ; GL.-Grindul Lupilor; Gv.-Gorgova (including the complex); GS.-Grindul Sărăturile; H.-Histria; Ig.-Ilgani; Le.-Letea; Ma.-Maliuc; Ms.-Musura; Mu.-Murighiol; ObM.-Obretinul Mare; Pa.-Pardina (agricultural polder); Pe.-Perişor; Po.- Popina Island; Pr.-Portiţa; Ps.-Periteaşca; Pv.-Periprava; Ru.-Rusca; Sa.-Sacalin; Sf.Ghe.-Sfântu Gheorghe; Si.-Sireasa; So.-Şontea (including the aquatic complex); SoPa.- Somova-Parcheş Complex; SS.-Sea side area (the area represented mostly by 2110 Natura 2000 habitat type); Su.-Sulina; Tu.-Tulcea; Ul.-Uzlina; Va.- Vadu (including Corbu area). Abbreviations used in the list for 1994 red list (V – vulnerable, R – rare, A - endemic, K – insufficient known, Ex extinct, B – European taxon, E – endangered, b – subendemic, DH2 – Habitat Directive) [12] and for 2009 red list (EN – endangered, CR – critically endangered, LR – low risk, VU – vulnerable) [6].

CONCLUSIONS There were enlisted 1215 vascular plant species, from which: 18% are included in the red lists with different conservation status, comparing the red lists (1994 and 2009) we can emphasize that more species turn into vulnerable or endangered; 5,4% are alien species, the relatively high number prove that this wetland is strongly disturbed by anthropogenic activities and climate changes; 3% are extinct or not recently found and 0,5% are endemic or subendemic.
