4.1 General site character

Habitat class % Cover

Total Habitat Cover


Other Site Characteristics

The waterside of the river Sazliyka for the most part is strongly influenced from negative impacts. The river is surround with agricultural lands. The waterside is afforested on the top end, but marshy on the lower reaches of the river. The Sazliika is a river in the South-Western Bulgaria, a left tributary of the Maritza River. It springs from the Surnena Sredna gora Mountains. The river valley in the upper current is narrow, shallow and deforested and in the lower current is widely cut into Pliocene and Quaternary alluvial deposits. Before the correction of the river-bed the river formed many meanders. Near the mouth there are well-developed accumulation and mixed terraces. The river is used for irrigation during summer. The river forms the Gulubovo reservoir and its tributaries form 12 small dams. The river runs mainly along arable land within the site. A small part of it is surrounded by plain broad-leaved forests. It is an important bio-corridor and a habitat of many species.The Gora Topolyane site is a former flood-plain forest along the Sazliika River. A part of it is still preserved. Dominant tree species are oak and poplar. There are humid meadows, 2 drying reservoirs and a micro-reservoir as well in this part of the site.

4.2 Quality and importance

After planting and recovery (partly on the waterside marshes), the waterside of the river Sazliyka would be ecocorridor, connecting the slopes of the Sredna Gora mountain and the river Maritsa.The site is an important bio-corridor and a habitat of many species. In Gora Topolyane area is one of the last remaining plain forests.In table "Ecological Information - Other Important species", the species justified by 'A-National' are not necessarily included in the National Red Data Book, because its last edition is too old (1985), not up-date and has no legislative value. The species indicated by 'A-National' are the protected flora and fauna species, included in the Bulgarian Biodiversity Act, and therefore this motivation is given highest priority. The Elaphe quadrolineata species found within the site is subspecies Elaphe quadrolineata sauromates.
