Impact of two types of management on arthropods diversity in olive groves
The intensification of olive production in Croatia, has involved a widespread use of tillage resulting in progressive loss of natural vegetation in comparison with traditionally managed ones with mowing or grazing. Tillage may impact the epigeic fauna and its diversity. To quantify that difference, we have analyzed epigeal arthropod diversity in 4 tilled and 4 mowed groves in Central Dalmatia. Field survey was undertaken in spring 2011 and arthropods were collected using pitfall traps filled with ethanol. Here, we compared higher taxonomic levels as a tool for rapid biodiversity assessment and carabid and spider species diversity to detect which method could better distinguish different management systems. Five groups of arthropods were recorded: Arachnids, Insects, Entognathids, Isopods and Myriapods. Altogether 6167 individuals have been sampled, with 84% of insects. All 5 groups were more abundant in the mowed groves than in the tilled ones. Among arthropods the highest portion of beetles (40%) were recorded, followed by ants and spiders. Although, there were almost equal numbers of beetle individuals in the both types of management, significant differences between the families were observed. Tenebrionid beetles were more abundant in tilled, while staphylinid and carabid beetles were more abundant in the mowed groves. Diversity of spiders also reflected different types of management. Obtained results imply that mowing is much better type of management in olive groves with respect to epigeic arthropod diversity. Higher taxonomic level methodology (HTLM) could be used to rapid assess of biodiversity in olive orchards at a local scale, in different managements regimes.
