英语. The aim of the present work was to determine the abundance and distribution of macrophytes in streams Bloščica and Cerkniščica and to establish the relation between environment characteristics and abundance of macrophytes. The environmental and macrophytes’ inventory was made on the whole length of the watercourse. We determined a presence, abundance and growth form of macrophytes and environmental parameters according to modified RCE Inventory. Nineteen taxa were found in the watercourse Bloščica and 20taxa in the watercourse Cerkniščica. Canonical correspondence analysis revealed that six environmental parameters significantly affected macrophyte community, the most influential being bottom structure, the width of riparian zone, retention devices in a channel and the land use beyond the riparian zone.

V prispevku podajamo rezultate raziskav pojavljanja, razporeditve in pogostosti makrofitov v vodotokih Bloščica in Cerkniščica ter ugotavljamo povezavo med okoljskimi razmerami in pojavljanjem makrofitov. Makrofite, njihovo pogostost, rastno obliko in stanje širšega vodnega okolja po prirejeni RCE metodi, smo popisali na celotni dolžini izbranih vodotokov. V vodotoku Bloščica smo popisali 19 taksonov, v vodotoku Cerkniščica pa 20 taksonov. Kanonična korespondenčna analiza je pokazala, da šest okoljskih parametrov značilno vpliva na pojavljanje in pogostost makrofitov. Največji vpliv imajo struktura dna, širina obrežnega pasu, zadrževalne strukture v strugi in zaledje.
