In total 231 higher plant species are established on the territory of the protected site. Five of the species are included in the Red Data Book of Bulgaria.
(Gypsophilla trichotoma Wend.)
(Silene euxina Rupr.)
(Eryngium maritimum L.)
(Lactuca tatarica L.)
(Coryspermum nitidum Kit.)
Amongst the plant communities the largest area is occupied by the formation of the reed (Phragmites australis). The height, thickness, the growth rate and the structure of its formations are very important for the formation of the composition of the bird fauna in the area (especially in the nesting sites).
The area between the road Burgas – Sozopol and the dyke embanked over the water pipeline is occupied by clear reed formations with a height of 1.6 – 1.8 m. To the east of the dyke, towards the sea, the reed is of smaller size. In the eastern part of the protected area, from the fence of the shipyard up to the dirt road, a reed formation could be observed, as well the wormseed and the sea rush (Phragmites australis (Cav.) Trin. ex Steud + Artemisia santonicum L. + Juncus maritimus Lam).
Along the sandy beach to the sea there are formations of mammoth wildrye, Indian plantain, rush skeleton reed, baby’s breath, sea holly and blue (Elymus sabulosus + Plantago scabra + Gypsophilla trichotoma + Eryngium maritimum + Lactuca tatarica).
In the western part of the protected area in places with shallow salt water pools are the formations of the glasswort (Salicornia europea L.). The formation of the Puccinellia convoluta (Atropis convoluta Grsb.) is situated in the central part.
A formation of sea rush, sea clubrush and widgeongrass (Juncus maritimus Lam., Bolboschonus maritimus (L.) Palla, Ruppia maritima L.) is found in the southeastern part of Poda Protected Site.
