The volunteers recognize LIFE

During the period 13-16 June, second phase of invasive plant species removal from the dunes of Natura 2000 site SCI “Pomorie” BG0000620 was implemented. These dunes are situated at the sand spit dividing Pomorie Lake and the Black sea and represent following habitats listed in the EU Habitats Directive 92/43/EEC – 2110 Embryonic shifting dunes and 2120 Shifting dunes along the shoreline with Ammophila arenaria ("white dunes"). The activity is part of action C4: Improvement of nesting conditions and removal of invasive plant species at Pomorie Lake within the project LIFE10/NAT/IT/256 MC-SALT Environmental Management and Conservation in Mediterranean Saltworks and Coastal Lagoons.

 

For the second time students from “Prof. Asen Zlatarov” high school provided precious voluntary support and actively cleared alien plants species that inhibit the development of protected local plant species associated with the dunes.

 

Sand dunes form several habitat types identified as conservation objective by European ecological network NATURA 2000. These provide suitable environment for variety of birds and valuable rare plants protected by Bulgarian and European legislation. Pomorie Lake sands dunes are not an exception and these harbour number of protected plant species. Some of these are: Sea rocket (Cakile maritima), Sea holly (Eryngium maritimum), Purple spurge (Euphorbia peplis), Yellow horn-poppy (Glacium flavum), and Trachomitum venetum. A great threat for local flora is not only coastal developments in the form of construction of resorts, golf courses, etc. but also invasive alien species like Indigo bush (Amorpha fruticosa), Spanish broom (Spartium junceum) and Snapdragon (Antirrhinum majus). These species were introduced primarily as decorative plants in the gardens and for reinforcement of slopes during road construction but nowadays these are spreading on vast territories causing threats for the development of local plant species. This is mainly because they are very well adapted to different environmental conditions – drought, floods, heat, cold, etc. The invasive species form large bushes that inhibit growing of the local plants – a common problem in the protected habitats like the coastal dunes. Therefore it is necessary to remove these alien plant species that have already overgrown sand dunes of Pomorie Lake. This is a priority conservation action in the protected area because invasive species already shown their negative effect.

 

The young student volunteers from “Asen Zlatarov” high school have proven once again that the hard work of removing invasive species is not a challenge for them. Through the whole period they eliminated invasive species Indigo bush (Amorpha fruticosa), Spanish broom (Spartium junceum) and Snapdragon (Antirrhinum majus) along 2,5 km length of the sand bar. Removed plants were dumped outside of the protected site at the municipal landfill.

Everybody was satisfied by the good results of the work done and positive impact it should have on the protected habitats. Along the work the students had the chance to learn more biodiversity of Pomorie Lake and goals and objectives of MC SALT project.
