Abstract

The Piedmont province of Biella, sandwiched between the Western Alps and the Po River valley, is unusual and diverse. Nearly 2% of its area is comprised of protected areas: Baragge are a relict heathland; Bessa is formed from debris of an ancient Roman gold mine; and Burcina Park is known for its rhododendrons. Historically, Biella was known for its rich textile industry. It has retained a wealth of natural forests and grasslands since ancient times and has proved to be suitable for beekeeping due to its mild climate and frequent precipitation that ensures continuous vegetative development. Beekeeping in the area, according to the Biella Beekeepers Association, includes 55 professional beekeepers and 3,579 bee hives, which are located mainly in the plains and low hills. An additional 199 amateurs and 1,127 registered hives exist mostly in the hills and low mountains. Interest from the local government and beekeepers themselves allowed Ferrazzi and Ferrero to research the area‘s bee flora and the Biella honeys. The work has led the most typical honeys of the area to be distinguished by the Agriqualità label of the Piemonte Region, featuring PAT (Traditional Food Products). The bee flora analysis was conducted through direct observations of honey bee foraging activity from 2006 to 2011. The honeys were evaluated from 140 samples submitted to melissopalynological, organoleptic, and physico-chemical (colour and moisture) analyses. The spring blooms of Taraxacum officinale, Salix and many genera of wild and cultivated Rosaceae (Prunus, Pyrus and Sorbus) were found especially important. The most relevant flowering is represented by Robinia pseudoacacia; Acer pseudoplatanus is also a strong contributor. Herbaceous Leguminosae, such as Trifolium repens and Lotus corniculatus were always attended by honey bees. Widespread Castanea sativa was also found to be an important crop as was simultaneousflowering Rubus. High altitude Rhododendron ferrugineum and Epilobium angustifolium are also excellent resources, the latter also present at low altitudes.
