Abstract. The Red List presented in this paper is focused on Bulgarian non-marine microalgae which face a
risk of extinction. The assignment to each IUCN Red List category is according to the seven specific criteria
and their relative values in the new method for an evaluation of the threatened status of microalgae (STOYNEVAGÄRTNER ET AL., this volume). The list contains 756 taxa (613 species, 82 varieties and 61 forms) from 7
divisions, classified in six IUCN categories and shows that threatened microalgae represent 14% the total algal
biodiversity of Bulgaria.
Key words: algae, Bulgaria, Red List, threatened species
In spite of having no legal definition, Red Lists are world-wide accepted valuable sozological tools for
designating the threatened status of organisms, which face an extinction risk and for raising the public
awareness for their conservation as well. However, algae, most probably due to their general belonging to the
invisible with the naked eye microscopic world, have been rarely considered as threatened (e.g. KRAUSE 1984;
RASSI & VÄISÄNEN 1987; GUTOWSKI & MOLLENHAUER 1996; KNAPPE ET AL. 1996; KUSEL-FETZMANN 1999;

BLAŽENČIĆ ET AL. 2006; SIEMIŃSKA 2006) and only 92 taxa, mainly marine macroalgae, have been included in
The IUCN Red List of Threatened Species,Version 2015-4.
In Bulgaria, the first Red List of macroalgae, based on standard IUCN criteria and categories, was
published as a first part of general Red List of Bulgarian algae (TEMNISKOVA ET AL. 2008). The paper title (Red
List of Bulgarian Algae. I. Macroalgae) clearly indicates the wish to create a second part oriented towards
country’s microscopic algae due to the recognition of their biodiversity and conservation importance. The task
was extremely difficult because of the obstacles in applying the standard IUCN criteria to the microalgal taxa,
using the recent knowledge on their distribution and taxonomy. Therefore the efforts of the author’s team were
devoted firstly towards the development of a new method for an objective evaluation of the threatened status of
the microalgae (STOYNEVA-GÄRTNER ET AL., this volume). The Red List of microalgae presented in this paper
is based on this method and was compiled after critical reading of all the references on their distribution in nonmarine habitats of Bulgaria.
The Red List provided below is organized in a table format in the following way: 1) algal taxa in main
taxonomic groups (after TEMNISKOVA & STOYNEVA 2011a,b), enlisted in alphabetical order according to their
recently accepted taxonomic name (mainly after GUIRY & GUIRY 2016); 2) assigned IUCN threat category
based on 3) the relative value of each of the seven criteria (A-G) fixed by STOYNEVA-GÄRTNER ET AL. (this
volume), which practically gives the exact formula for each algal taxon and 4) its total counts (T). As it is
proposed in the method description, in further publications or reports such formula could be used separately for
each taxon: e.g. Anabaena pirinica Petkoff [CR - A3 B3 C4 D4 E4 F4 G4]. In case of special insistence on the
level of the importance of the species due to its total counts, the formula could be expressed as Anabaena
pirinica Petkoff [CR - A3 B3 C4 D4 E4 F4 G4 T25], or could be used in its short versions (e.g. Anabaena
pirinica Petkoff [CR - T25], or Anabaena pirinica Petkoff [CR]).
According to the IUCN recommendations in the Guidelines for Application of IUCN Red List Criteria at
Regional Levels (Versions 3.0, 2007 and 4.0., 2012) we avoided the general categories ‘Extinct’ and ‘Extinct in
the Wild’. Taking into account the lack of recent investigations in some of the localities, we decided to avoid
also the category ‘Regional Extinct’ even for species, which have not been confirmed for the territory of
Bulgaria during the last five (or more) decades. The other categories (Critically Endangered, Endangered,
Vulnerable, Low Risk /Near Threatened, Least Concern/ and Data Deficient) were designated according to the
total counts for each species, obtained after applying the seven criteria and their relative values proposed in
STOYNEVA-GÄRTNER ET AL. (this volume). Due to the restricted volume of the paper, the synonyms are
provided only for a few taxa, described from Bulgaria and references concerning the distribution of the included
algae are enlisted only in the end of the paper. A special note has to be made for some mesoalgae, which could
be visible macroscopically, but could not be identified even on generic level without a light microscope (e.g.
Oedogonium, Mougeotia, Zygnema). Their representatives are included in the present list with one exception –
Spirogyra rhodopea Petkoff, which has been enlisted as a Data Deficient species in TEMNISKOVA ET AL. (2008).
Since the recent algal biodiversity in Bulgaria is quite rich – ca. 5500 taxa (STOYNEVA 2014), a
preliminary screening of the species was done by the author’s team in an effort to elucidate the most rarely
reported algae in Bulgarian phycological literature since the first publications by ISTFANFFI (1890) and PETKOFF
(1898a-c) till nowadays. Afterwards the chosen algae were evaluated according to the method of STOYNEVAGÄRTNER ET AL. (this volume). Therefore it is possible to expect that further checking could outline more
threatened microalgae in the country.
The proposed Red List of threatened Bulgarian non-marine microalgae contains 757 taxa (613 species,
83 varieties and 61 forms) from 7 divisions classified in six IUCN categories (Appendix 1, Table 1) and the
number of the threatened taxa in these categories and main taxonomic groups is shown below in Table 2.

The number of threatened species, varieties and forms of microalgae in the present Red List shows that
they comprise 14% of the total algal biodiversity of Bulgaria, and together with the 88 threatened macroalgae
enlisted in TEMNISKOVA ET AL. (2008), they constitute 15% of all algae reported for the country.
Table 1. Red List of Bulgarian microalgae: CS - conservation status (CR - Critically Endangered, EN Endangered, VU - Vulnerable, NT - Near Threatend, LC - Least Concern, DD - Data Defficient); A-G criteria in 1-4 categories (described in details in Stoyneva et al., this volume), where: A - number of localities,
B - affiliations to protected habitats of Bulgaria, C - affiliation to ecological category, D - affiliation to
protected territories, E - endemism, F - general geographic distribution, G - expert weight and T - total
counts. In quotes are given the original writting-outs of DD infraspecific taxa, which belong to species which have
been taxonomically transferred, or taxa with author names which have been not found by the authors of this paper in
the available taxonomic literature.
