Résumé partiel
Through various research techniques the floral resources of primary importance to commercial beekeeping interests within New South Wales (NSW) were established. Each method placed a different emphasis on what it is that was being evaluated. Surveys were probably the best method of encompassing all the aspects considered by beekeepers to be important pertaining to floral resources. The aspects considered of primary importance included nectar secretion, ultimately measured by honey produced, and the nutritional impact of pollen collected by honey bees on the colony. A survey of all commercial beekeepers registered with the NSW Government under the Apiary’s Act 1985 produced an 81% response. A total of 51 floral species were identified to be of primary importance to beekeepers. The top 10 listed in order were Echium plantagineum, Eucalyptus melliodora, E paniculata/E. siderophloia, Corymbia maculata/C. variegata, Brassica napus, E. macrorhyncha, E. camaldulensis, E. sideroxylon, E. albens and Trifolium repens. A total of 238 floral species were mentioned by beekeepers as important to their beekeeping business. In the State survey there was evidence of Victorian beekeepers periodically utilising flora within NSW, moreso than NSW beekeepers utilising flora within Victoria, also the same north/south movement on the Queensland border with NSW beekeepers tending to utilise flora north of the border moreso than Queensland beekeepers relying on the floral resources within NSW. The total honey production per colony increased with the number of hives managed by each beekeeping business from 41 kg/hive for operations managing less than 200 hives, to a peak of 111 kg/hive for operations managing between 801 and 1000 hives.
