SUMMARIES OF RED DATA BOOKS IN THE BLACK SEA COUNTRIES
1. BULGARIA
by Tsonka Konsulova
The "Red Data Book (RDB) of the Republic of Bulgaria" was published in 1985 in
order to make the public familiar with the prevailing state of plant and animal species
which were found only infrequently in the country, e.g. they were not as widespread
as "ordinary ones". Three categories of deficiency were adopted:
-Category A - plant and animal species and subspecies that had disappeared or
become extinct
-Category B - plant and animal species and subspecies that were threatened either
because of an unfavorable change in their habitats and narrow ecological niches or
because of poor self-restoration of their populations
-Category C - rare plant and animal species, which either consisted of only a very
small number of specimens or were extremely limited in occurrence and which, if no
urgent measures were taken for their protection, were in danger of becoming extinct.
The two-volume Bulgarian RDB provides a sound basis for a large number of
initiatives and statutory acts aimed at the improvement, protection and restoration of
the species included. It also serves as a basis for the adoption of measures to protect
other species that are not yet included in it. The species in the Bulgarian RDB were
classified according to our present level of knowledge on their "genetic fund" (= their
total genetic variation or gene pool); this knowledge is rather scarce on certain groups
of plants and animals. Volume 2 of the Bulgarian RDB includes information on 157
vertebrate species of the classes Cyclostomata, Osteichthyes, Amphipoda, Reptilia,
Aves and Mammalia. The description of each species contains the following
