Abstract

Alepu marsh is a protected area in the category of natural landmarks, part of the Ropotamo Ramsar site and sand dunes Alepu. It is situated on the Bulgarian Black Sea coast, within Burgas Province, south of the resort town of Sozopol. It is also situated within the territory of the protected area of the European ecological network Natura 2000 under the Birds directive – Ropotamo Compex. Alepu marsh is covered with reeds and other swamp vegetation. The area is habitat for many rare animals and plant species. The main problem of this area is the overgrowing with reeds and the gradual swamping that leads to reduction of the open water areas in the protected area. This leads to the loss of valuable habitats, and respectively their inhabiting animal and plant species. In the study paper assessment of the dynamics of the marsh for a period of eight years (2013 – 2020) was done. Data from Landsat 8 and Sentinel 2 were used. Classification of NDVI was made for this study period. Sentinel 2 data were also used to apply an orthogonal transformation model that classifies and analyzes the processes associated with the dynamics of change affecting the main components of the earth's surface: soil, water and vegetation. The NDGI model was also used, which evaluates the dynamics of the vegetation in the marsh. The results obtained show a monitoring of the wetland for a sufficiently long period of time, which gives an idea of its condition and the need to take the necessary conservation measures for its protection.
