samo po postojećim stazama i u svrhu znanstvenih istraživanja. Osnovno polazište glede namjena šuma unutar zaštićenih područja je osiguranje potrajnosti ekosustava, održavanje općekorisnih funkcija i biološke raznolikosti, produktivnosti, obnavljanja i vitalnosti šuma u svrhu ispunjavanja ekoloških i socijalnih funkcija.
Rad je nastao u sklopu Projekta: Istraživanje šumskih ekosustava NP Brijuni, 2017. godine. Zahvaljujemo djelatnicima NP Brijuni na suradnji

Summary
The area of the Brijuni archipelago, due to geomorphological-hydrological, climatic, natural and anthropogenic influences, makes up one of a few preserved natural, cultural and landscape values in the Adriatic. In the area of Veli Brijun, there are alternating elements of several forest stand types on a relatively small surface. The anthropogenic factor influenced the disappearance of parts of forests through logging and infrastructure construction. The second factor is excessive numbers of wildlife on the island. Consequently, two test surfaces were formed intended for ecosystem monitoring on the island of Veliki Brijun: one in the fenced area of the residential park of the White Villa (No. 57) and the other in the free space in the area referred to as the Dead Peak (No. 56). The research behind this paper was conducted in May 2017 on both permanent experimental plot within which vegetative-ecological and structural features of these stands were analysed. The obtained results were compared with the most recent previous measurement of the same surfaces conducted in 1988. Based on the processed data, huge differences were identified between the measured surfaces. The floristic aspect further accentuates the differences between the two localities. In the permanent experimental plot No. 56, there is hardly any shrub layer, while in the permanent experimental plot No. 57 the latter is extremely developed. Moreover, in addition to floral scarcity on the permanent experimental plot No. 56 it is important to highlight the impossibility of natural stand regeneration, while on the permanent experimental plot No. 57 dense sprouts and young growth were recorded. Considering the measured elements of stand structure in 1988 and in 2017, the stand in the permanent experimental plot No. 57 develops and grows naturally, while the stand in the permanent experimental plot No. 56 is undergoing a phase of regression and degradation due to a large influence of wildlife. First of all, the numbers of allochthonous wildlife in the specific part of the island need to be reduced to numbers that enable stand sustainability. The permanent test surface No. 57 and the surrounding area need to be preserved as a special forest vegetation reserve and measures need to be implemented within this protection category.
