Abstract
About 200 species of bryophytes are currently known from Egypt. The majority are mosses, only 13 species belong to the liverworts while no hornworts exist. Regarding the liverworts, and following simplified methods used by previous workers, 11 out of the 13 species are listed under threatened categories; 6 of them are in the CR category, 4 in the EN category, 1 in the VU category and 2 are considered not threatened. This evaluation documents the situation at the time of collection, i.e. from 1958 to 1999, which is quite a long time, however, it is basic for any future Red Listing of bryophytes in the country.
Highlights
Just over 200 bryophytes are, hitherto, known from Egypt (El-Saadawi and Shabbara, 2007; El-Saadawi et al, 2015; El-Sakaty et al, 2018; Khalil and Farag, 2018; Hassan et al, 2019; Taha and Holyoak in Ellis et al, 2019; Taha, 2020)
In this article the authors try to assign the 13 hepatics known from Egypt to the conservation categories of threatened species following the methods used by Martinčič (2016) in which species were classified under the Red List categories taking in consideration the only realistic threat assessment criterion, which is expressed in the number of currently known localities: 1 (Critically Endangered "CR"), 2-5 (Endangered "EN"), 6-10 (Vulnerable "VU")....etc
It is clear that quite a small number of hepatics are recorded in Egypt; all are Marchantiales except Riella (Sphaerocarpales); all are rare and classified under threat categories (6 CR, 4 EN, 1 VU) except Riccia cavernosa and Riccia frostii which are considered not threatened being reported repeatedly from many localities in at least five of the phytogeographical territories of the country (El-Saadawi and Shabbara, 2007)
Summary
Just over 200 bryophytes are, hitherto, known from Egypt (El-Saadawi and Shabbara, 2007; El-Saadawi et al, 2015; El-Sakaty et al, 2018; Khalil and Farag, 2018; Hassan et al, 2019; Taha and Holyoak in Ellis et al, 2019; Taha, 2020). A list of threatened bryophytes in Egypt is, much needed.
