Investigating the relationship between Australian almond
pollinators and their foraging landscape
POLLINATION SERVICES IN
AGRICULTURAL LANDSCAPES
BACKGROUND

Australia—fastest growing almond industry in
world

Almonds rely 100% on bee pollination

Nearly 164,000 honeybee hives per year for
Australian almonds
RESEARCH NEEDS
Potential native almond pollinators
 Annual crops…Tree crops
 Tropical systems…Temperate systems
 Natural enemies…pollinators
 Temporary species ‘invasion’

AIMS
Potential native pollinators of almonds
 Macro- vs micro-agriculture
 Homeless honeybees
 Agricultural landscape structure and pollinator
relationship

RESULTS SO FAR…

More flowering ground cover = more insects

Small farms/edges of large farms = more
insects

WHAT NEXT?
More sampling
 Local honeybee populations
 Small-scale ‘mosaic’ farms vs large-scale
monocultures
 Management practice or farm size?
