Abstract

Budući da u posljednjim desetljećima čovjekov pritisak na prirodu postaje sve veći, samim time i proljetnice postaju izravno ugrožene čovjekovim djelovanjem. Svaka promjena klime, tla, izostanak košnje, promjena vodnog režima direktno utječe na floru i faunu nekog područja. Po svojim ekološkim značajkama područje jezera Ljubljanica – Odransko polje čini veoma osebujnu zajednicu vlažnih livada kod kojih je značajna izmjena vlažne i suhe faze tla. Terensko istraživanje izvršeno je u tri navrata, u proljeće i jesen 2015. godine, te u proljeće 2016. godine. Nasumično je odabrano sedam mikrolokacija na kojima je inventarizirana proljetna flora, a biljne vrste su sakupljene i herbarizirane. Analizom proljetne flore unutar zaštićenog područja Ljubljanica – Odransko polje, zabilježena je ukupno 51 biljna svojta, od toga 10 proljetnica što čini 5,1%. Ustanovljena je vrsta četverolisna raznorotka (Marsilea quadrifolia) koja je zakonom zaštićena i uvrštena u Crvenu knjigu vaskularne flore Hrvatske. Od proljetnica su zabilježene sljedeće vrste: kockavica (Fritillaria meleagris), livadna režuha (Cardamine pratensis), nekoliko vrsta iz roda žabnjaka (Ranunculus sp.), proljetni drijemovac (Leucojum vernum), šumski kopitnjak (Asarum europaeum) i mirisna ljubica (Viola odorata). Zastupljenost vrsta odnosno procjena pokrovnosti proljetnica na ovom području nije istraživana, te bi njihovu zastupljenost ubuduće trebalo bolje nadzirati.

Abstract (english)

Since the last decades of human pressure on nature is becoming greater, thus the spring flowering species are directly threatened by human activities. Every change of temperature of field, every skip of mowing, rising or falling of the water, every hidromeliorative operation etc. has a directly impact on flora and fauna of the certain area. By its ecological features, the area of Lake Ljubljanica – Odransko polje seems very peculiar community of wet meadows with significant changes of wet and dry soil phase. Field research was carried out on three locations, in spring and autumn 2015 and spring 2016. Seven micro–locations were randomly selected where the spring flora was inventoried and plant species were collected and herboried. The analysis of spring flora within the protected area Ljubljanica – Odransko polje, recorded a total of 51 plant species, of which 10 spring flowering species which makes 5.1% of the recorded species. There was also detected a protected species, Marsilea quadrifolia which is listed in the Red Book of Croatian vascular flora. Following types of spring flowering species were recorded: fritillary (Fritillaria meleagris), Cardamine pratensis, some species of the genus Ranunculus sp., spring snowflake (Leucojum vernum), forest wild ginger (Asarum europaeum) and sweet violets (Viola odorata). Spring flowering species are not numerous in this area and their occurrence and abundance should be better monitored.
