Vascular flora of northeastern part of island Cres

Abstract

Tijekom 2006., 2007. i 2008. godine istraživana je vaskularna flora sjeveroistočnog dijela otoka Cresa. Na području površine 15 km2 nađeno je 329 svojti vaskularnih biljaka iz 219 rodova i 70 porodica. Najučestalije porodice su Poaceae (10,94%), Fabaceae (9,11%) i Lamiaceae (6,99%). Analizom flornih elemenata utvrđeno je najviše hemikriptofiti (40%), zatim slijede terofiti (26%), fanerofiti (12%), hamefiti(10%) i geofiti (9%), a najmanje ima epifita, hidrofita i parazita (zajedno 3%). Analiza flornih elemenata pokazala je najveću zastupljenost široko rasprostranjenih vrsta (18%), a nešto manje su zastupljene cirkummediteranske biljke (16%) i južnoeuropskomediteranske biljke (15%). Ekološke analize su samo potvrdile submediteranske karakteristike tog područja. Analizom endema, zaštićenih i ugroženih svojti utvrđeno je 19 endema, 1 ugrožena i 1 osjetljiva svojta, 8 gotovo ugroženih svojti, te 42 zaštićene i 23 strogo zaštićene svojte.The research of vascular flora of northeastern part of island Cres was carried out during 2006, 2007 and 2008. 329 taxa from 219 genera and 70 families was found on the area range 15 km2. The most abundant families are: Poaceae (10.94%), Fabaceae (9.11%) and Lamiaceae (6.99%). Analysis of life forms showed that hemycryptophyta are dominant (40%), followed by therophyta (26%), phanerophyta (12%), chamaephyta (10%) and geophyta (9%). There were the least epiphyta, hydrophyta and parazites (together 3%). Phytogeographical analysis showed that widespread plants are dominant, with 18% of taxa, followed by Circum - Mediterranean plants (16%) and South European – Mediterranean plants (15%). Ecological analsys only confirmed the submediterranean caractheristics of the area. On the researched area 19 endemic taxa were found, as well as 1 species with a very high extincion risk, one with a high extincion risk, 8 nearly threatened species, 42 protected and 23 strictly protected species
