Sažetak
These papers analyze the impact of forest litter in connection with forest fires. The ecological values of the litter are displayed and such measures necessary to reduce the risk of fire. The amount of litter indicates that there are differences between vegetation zones. The differences can not be established between different pine stands. In this study black pine, aleppo pine and maritime pine were researched. Brown soil on limestone have the highest amount of organic substances, typical (15.89 t / ha), while the lowest amount was recorded at the rendzina on marl (7.66 t / ha) for stands of black pine. Researches of forest litter showed strong influence of climatic factors on its quantity and composition. In this research some principles can be verified and may lead to connection with forest fires. First, large amounts of litter in the area eumediterranean are subject to slow decomposition for a long dry season and less humidity. On the other hand, such conditions may affect biological properties of species, that is the creation of small quantities of needles because of less favorable habitat conditions. In sub-Mediterranean area habitat conditions are more favorable, but due to lack of implementation of forest-silvicultural work and large amounts of organic matter mineralization processes and humification are slowing down. In a case of monocultures where return of deciduous vegetation is less frequent, climate-zonal problem is even more pronounced. However, in the research area and area along the Croatian Adriatic coast is dominated by pine culture. Measures that would affect the reduction of fire risk relate to quality approach to forest and forest land management. It is necessary to evaluate and better management of forest pine cultures, and to encourage more intensive forms of stand conversion where the major is protective role.
