Structural features of phytocenoses on permancnt experimental plots of the Special forest vegetation reserve "Lokrum"

Otok Lokrum nalazi se nedaleko od Dubrovnika na jugu Republike Hrvatske. Prekriven je vazdazelenom šumskom vegetacijom i makijom, a samo manji dio čine otvorena staništa te morska obala. Od ukupne površine Lokruma od 0,72 km², čak 80% iste je prekriveno gustom vegetacijom. Zbog sadržaja svih prirodnih razvojnih nizova biljnih zajednica eumediteranskog područja na takvoj maloj površini, otok je zaštićen kao Posebni rezervat šumske vegetacije. Osnova za pisanje rada su trajne plohe utemeljene 1987. godine s namjerom upoznavanja biološko-ekoloških i strukturnih obilježja šumske vegetacije te budući tijek razvijanja istih. U radu se provodi usporedba postojećih podataka iz prijašnjih istraživanja (1987. i 2011.) sa trenutnim stanjem.The island of Lokrum is located near Dubrovnik in the south of the Republic of Croatia. It is covered with evergreen forest vegetation and macchia, and only a small part consists of open habitats and the coast. Of the total area of Lokrum of 0.72 km2, as much as 80% is covered with dense vegetation. Due to the content of all natural developmental series of plant communities of the eumediterranean area in such a small area, the island is protected as a Special reserve of forest vegetation. The basis for writing this master paper are permanent plots created in 1987 with the intention of getting to know the biological- ecological and structural features of forest vegetation and the future course of their development. The paper compares the existing data from previous research (1987 and 2011) with the current situation
