Sažetak
This paper presents the results of research into the effects of stands of black pine (Pinus nigra Arn.) and Aleppo pine (Pinus halepensis Mill.) on the protection of soil from rain-induced erosion. Research was conducted in the watershed of the torrent Suvava at Muć in experimental plots B4 and B5 inhabited by old stands of black pine at an inclination of 32°, and in the watershed of the torrent Rupotine near Solin in experimental plots B8 and B9 containing preserved and burnt stands of Aleppo pine at inclinations of 26 and 20°. The estimated mean annual values of surface runoff in old and open stands of black pine with completely preserved humus accumulative horizon covered with thick grass, at an inclination of 32° (plots B4), were 16.17 mm/m2 (161.7 m3/ha), with the runoff coefficient of 0.015 and soil loss of 0.0107 t/ha. Surface runoff in fully canopied stands of black pine and no grass cover, at an inclination of 32° (plot B5), amounts to 31.65 mm/m2 (316.1 m3/ha), with the runoff coefficient of 0.027 and soil loss of 0.0196 t/ha. In the fully canopied preserved stands of Aleppo pine, at an inclination of 26° (plot B8), surface runoff amounts to 6.23 mm/m2 (62.3 m3/ha), with the runoff coefficient of 0.0087 and soil loss of 0.044 t/ha, and in the burnt area at an inclination of 20° (plot B9), surface runoff amounts to 35.51 mm/m2 (355.1 m3/ha), with the runoff coefficient of 0.0478 and soil loss of 19.93 t/ha. According to the results, , erosion-induced soil loss in the burnt forest area at an inclination of 20° is 463 times greater than under the preserved stands of Aleppo pine at an inclination of 26°.
