Sea water flood resilience of five plant species with conservation status over the Bulgarian Black Sea Coast

The Bulgarian Black Sea coastal zone is relatively protected from sea floods. Only extreme meteorological events such as unusual storms can cause flooding of areas. Crucial for the application rapid methods vulnerability assessment plant communities caused by over Coast to obtain experimental data water flood resilience. This study aims determine species survival in simulated experiments order identify resilience five with conservation status: Centaurea arenaria M. Bieb. ex Willd., Crambe tataria Sebeok, Aurinia uechtritziana (Bornm.) Cullen & Dudley, Silene thymifolia Sm., and Stachys maritima Gouan. As a result experiment, Critical Decomposition Time (CDT) was obtained. were within most vulnerable group (CDT < 48 h). CDT significantly shorter than floods maximum duration Coast. values parameter beginning decomposition leaves accelerated higher temperatures. Other parameters unrelated different investigated have low rates degree their will not be able recover after one vegetation season.
