Abstract:

Apiarists in Austria are under the impression that the diversity of grasslands is decreasing over the last few years. Scientifically it is proved that the connection between plant diversity and exploitation methods as well as exploitation frequency is eminent. In order to discover the influence of different ways of utilisation in grasslands on the potential nutrition for Apis mellifera, plant species were documented on nine different trial fields in the Ennstal-area during the growing season in 2015. Weekly enquiries were made. The experimental area included single cut meadows, meadows with two, three or more than three cuts per year, field forage and permanent pasture. Statistical evaluations were made by means of this collected data, as well as differences between mountain and valley areas distinguished. There is a diminution within utilisation forms from extensive to intensive cultivation, however there are also methods to improve the concomitance of blooming plants which are important for honeybees. Additionally, there is a difference between the amount of plant species on fields in valleys or mountains. Montane areas are rich on plant species and they appear to have higher surface coverage of blooming plants. Mowing dates and mowing frequencies have a high impact on available blooming plants. If the cutting range of equally or divers cultivated fields is delayed by one to three weeks, the surface coverage is highly improving. Only a mosaic display of cultivation can keep a steady surface coverage of blooming plants which is important for the nutrition of honeybees. This is a possible way that seems to fulfil the demand of famers economically, as well as it adds value to the nutrient of Apis mellifera. And the result of these actions will serve the general public.
