Dr Karyne Rogers, GNS Science

The core idea of both this Trees for Bees Conference and next year's is to greatly increase our knowledge of trees bearing high-protein pollens that can nourish bees (of all types - honey bees, bumble bees, native bees) especially during times of pollen shortage. Linda Newstrom-Lloyd is concentrating on collecting and analysing pollen from bees visiting both native and exotic flowers, especially honey bees.

Her recent research at Eastwoodhill has been on spring flowering species that will help honey bees in the critical phase of population build-up from August to October, before the bees are needed for pollination services and honey harvesting.

The conference planned for next year will look more closely at trees that produce pollen in the autumn when bees are collecting their stores for overwintering. Both these times of year are critical and often have pollen shortages so planting out high-protein pollen bearing species will benefit all bees.

The great thing about Eastwoodhill Arboretum for this type of research is the huge diversity in the 12,000+ catalogued trees and shrubs. These represent around 147 families, 475 genera and 1663 species plus over 150 hybrids. This diversity concentrated in one area has facilitated the research on bee forage, as many of these species are undervalued for this purpose and not on bee plant lists.
