The NSW Department of Primary Industries and Regional Development (NSW DPIRD) has released a new report revealing the pasture legume flowers that are the most attractive to Australian honeybees.
NSW DPIRD senior research scientist and Clover4Bees project leader, Dr Richard Hayes said primary producers have always had the option to use forage legumes that support honey production, thereby enhancing resources for honeybees and fostering collaboration with apiarists. However, little was known of the relative value of the range of pasture legume species for honey bees – until now.
The two-year pilot project, funded by AgriFutures Australia, evaluated 23 different pasture legume species across four NSW DPIRD research stations, focusing on their flower attributes, bee preferences, and nectar characteristics.
"Out of 23 pasture legume species, six leading contenders were selected based on their flower attributes, bee preferences, and nectar characteristics," Dr Hayes said.
"Species like subterranean clover and biserrula were found to have low nectar yields and sugar concentrations, resulting in few bee visits.
"Meanwhile, our top performers were woolly pod vetch and arrowleaf clover, which showed high potential due to their attractiveness to bees."
Balansa clover, gland clover, Persian clover, and crimson clover were also identified as highly enticing for honeybees, making them excellent candidates for supporting honey production and pollination.
Dr Hayes said the Clover4Bees project highlights the need for further research and collaboration with other agricultural sectors to enhance the use of these legumes.
"The results have come at a crucial time as environmental challenges and limited access to public lands have prompted the honeybee industry to explore alternative floral resources," he said.
"By creating a more pollinator-friendly landscape, all Australian agricultural industries can collectively ensure the sustainability of honey production and support the health of bee populations in the face of challenges like the varroa mite."
