National Park Risnjak is located in Gorski kotar, western part of Croatia. Park covers an area of 64 km2 and its peak, called Veluiki Risnjak, is 1528 m a.s.l. The average amount of percipitation is 3579 mm and annual temperature is 6, 5 0C. According to the Koppen climate classification , the study area belongs to the snow-forest climate with cold summer - Dfc. The main part of Risnjak massif is formed predominantly of limestone and the rest is dolomite. Geological structure, together with climate, is the main factor of development of almost 1000 plant taxa. Floristic research conducted in August 2006 covered the woodland area between Veliki Risnjak and Bijele stijene, with an overall area of 5 km2. In this study, 210 taxa of vascular plants from 57 families were found. The most abundant families are Asteraceae (9, 0%), Ranunculaceae (7, 1%), Apiaceae (6, 7%), Liliaceae (6, 2%), and Lamiaceae (5, 7%). In the life form spectrum, hemicriptophyta are dominant (62.9%) followed by geophyta (13, 3%)chamaephyta and nanophanerophyta (each 7, 6%), phanerophyta (6, 2%) and therophyta (2, 4%). In the Red Book of Vascular Flora of Croatia, 16 taxa are listed (VU 6, NT 8, LC 1, DD 1). According to the Nature Conservation Act, 13 taxa are strictly protected and 48 taxa are protected. The most valuable contribution of this study is the discovery of five new species for the flora of Risnjak: Bromus ramosus Huds., Dryopteris expansa (C.Presl) Fraser-Jenk. et Jermy, Goodyera repens (L.) R.Br., Scabiosa hladnikiana Host i Trifolium ochroleucon Huds. |
