Abstract
Invazivne vrste su agresivne i brzo se rašire staništem. Na takvim staništima broj autohtonih vrsta se smanjuje zato što im invazivne vrste uzimaju prostor i hranu, a nekima su predatori. To dovodi do smanjenja biološke raznolikosti koja je uvelike važna za zaštićena područja. U ovom su radu navedena glavna obilježja nacionalnih parkova i parkova prirode u Hrvatskoj i ukratko su opisane neke invazivne vrste koje su ih naselile. Navedeno je njihovo podrijetlo, način unosa, prilagodbe koje su im omogućile opstanak na novom staništu, razlog zašto se smatraju invazivnima na određenom području te mogući načini uklanjanja.Invasive species are aggressive and they spread rapidly in the habitat. In such habitats, the number of autochthonous species decreases because invasive species take their place and food, and some invasive species are predators to the autochthonous species. This lead to the reduction in biodiversity which is extremely important for protected areas. In this paper I mention the main features of national parks and nature parks in Croatia and briefly describe invasive species that have settled in them. I discuss their origin, the way of entry, adaptation that allow them to survive in a new habitat, the reason why they are considered invasive in a given area and the possible ways of their removal
