Abstract

U NP Sjeverni Velebit u znatnoj mjeri prisutan je trend napredovanja prirodne šumske vegetacije (sukcesija) na područjima svih tipova travnjaka, posljedica čega je gubitak njihove biološke raznolikosti. Stoga se pristupilo utvrđivanju najugroženijih travnjaka odnosno onih koji su najviše zahvaćeni sukcesijom. Interpretacijom DOF-a iz 2007. godine i satelitske snimke visoke prostorne rezolucije IKONOS iz 2010. dobili smo uvid u stanje travnjačkih površina Parka. Zatim smo izradili tematske karte travnjaka kako bi ih usporedili sa travnjacima kartiranim na TK25 iz 1977. godine. Na temelju usporedbe travnjačkih površina iz navedenih izvora utvrđene su površine na kojima je došlo do sukcesije. Dobiveni slojevi su uklopljeni u GIS model područja istraživanja te su na taj način omogućene različite prostorne analize. Također, ukazano je i na značaj daljinskih istraživanja pri uspostavi GIS-a za monitoring.

Abstract (english)

In NP „Sjeverni Velebit“ there is a notable progressing of natural forest vegetation trend (succession) in all types of grasslands, resulting in loss of their biological diversity. Therefore, we approached determening most endangered grasslands, those which are affected by succession the most. Interpreting DOP from 2007. and high resolution satelite images IKONOS from 2010. we got an insight in the condition of grassland surfaces of the Park. Then we made thematic maps of the grasslands so that we could

compare them with grasslands maped on tophographic map 1:25000 from 1977. We determined surfaces which were affected by succession based on comparison of grassland surfaces from sources stated above. Obtained layers of area of research are fitted into GIS model and in that way different space analyses were enabled. Also, we indicated significance of remote sensing at establishment of GIS for monitoring, diversity. Therefore, we approached determining most endangered grasslands, those which are affected by succession the most. Interpreting DOP from 2007. and high resolution satelite images IKONOS from 2010. we got an insight in the condition of grassland surfaces of the Park. Then we made thematic maps of the grasslands so that we could compare them with grasslands mapped on tophographic map
