General Structure of the Black Sea Red Data Book

The Black Sea Red Data Book is prepared in two versions:

It is also planned to prepare a conventional book (with the sheets for each species description).

The Red Data Book is consist of:

• an introduction;
• sheets (files) describing threatened species;
• annexes (references, indexes).

The book is written in English. The scientific names of each species will also be given in Latin and in the official languages of the Black Sea countries (Bulgarian, Romanian, Russian, Turkish and Ukrainian).

The species descriptions (sheets/files) are divided into several chapters according to plant and animal taxonomy. The sheet/file of each species description includes the following information:

• names: full scientific name, synonym(s), common names;
• taxonomy: order, family, taxonomic comments;
• picture of a species (the best for identification)
• IUCN status: global status, Black Sea regional level (regional view on population status), subregional (national) levels;
• distribution (including a map);
• habitat type, critical habitats, limiting factors;
• notes on biology;
• population trends (since the 1960s, including the dynamics of species numbers);
• threats (anthropogenic impacts);
• conservation measures taken;
• conservation measures proposed;
• references.
