Sažetak
This paper points to problems of natural reforestation of burnt areas in the stand of Aleppo pine (Pinus halepensis Mill.) On a permanent sample plot set in the Forest Office Sibenik. Over the successive five-year survey (2001 to 2005.) Was monitored during growth and development of vegetation by type, number and height-age classes. Number of plants of Aleppo pine indicates a successful, highly abundant natural regeneration, but the problem is the lack of native vegetation in areas affected by fire. Measured 106000-121000 plants per ha shows that young plants of Aleppo pine abundance, height and 2.5 m over the burned material is grown and fully covered the burned area.
A special part of the research concerns the effects of treatment and rehabilitation work after the fire was investigated at three permanent sample plots in the field of forestry Sibenik, Split and Korcula. Research indicates a change in approach to rehabilitation of the burnt areas by omitting unnecessary, tedious, and costly stacking the remaining burnt material on the track. This highly complex material in air, in the Mediterranean climate conditions, very slowly breaks down and the long years of its mass increases the already ever present danger of fire, and distorts the landscape. It is recommended that rehabilitation care and fragmentation of material combusted on the surface of a chainsaw so that the remaining material to the soil as much as possible. Moisture from the soil and microclimate conditions of young stands of Aleppo pine, which will be processed by the material found, will contribute to the rapid development of microorganisms, its faster degradation and humification. Aleppo pine, a species of Eumediterranean, has a significant and irreplaceable pioneering role in greening the devastated area, but also in terms of site preparation for the arrival of indigenous vegetation, especially the oak as the basic types of this area.
