Operation Pollinator

Recent efforts to re-establish declining
pollinator species have focused on curbing losses
of honeybee populations due to colony collapse
disorder. But scientists argue that a focus on
wild pollinators is an equally worthwhile
strategy. To that end, agribusiness giant
Syngenta (Basel, Switzerland) has begun a 1
million program, dubbed Operation Pollinator,
to boost native pollinating insects across
Europe, by planting low-cost seed mixtures
containing specific pollen- and nectar-rich
forage plants near agricultural lands.
Habitat loss, stemming from changes in land use
and intensification of agriculture, is widely
agreed to be the major driver of wild pollinator
losses across the UK and Europe, says ecologist
Claire Carvell (UK Centre for Ecology and
Hydrology, Wallingford, Oxfordshire). Carvell
helped develop plant mixtures that when sown at
the edges of cropped fields boost bumblebee
numbers more than 30-fold. These mixtures were
developed as part of Operation Bumblebee, a
collaboration with Syngenta that resulted in over
1000 planted hectares. Despite the initial
emphasis on bumblebee-oriented plants, the
mixtures increased the number and diversity of a
wide range of pollinators, including butterflies
and non-social bee species, such as mason bees.
Interestingly, Carvel found that sowing these
mixtures into more intensively farmed areas
attracts higher densities of bees than sowing
into more biodiverse areas suggesting that
planting mixtures in poorer quality landscapes will have greater benefits.
Syngenta, in collaboration with the National Fish
and Wildlife Foundation (Washington, DC), is
currently expanding their efforts to key
horticultural areas in the US, including
California, Florida, and Michigan. The
independent research will define the preferred
seed mixtures for specific ecoregions and develop
activities to establish and manage pollinator
habitat. The goal is to develop land-use
management practices that are practical and cost
effective, and will improve productivity on the
farm, says Jeff Peters, Sustainability Technical
Manager at Syngenta Crop Protection (Greensboro,
NC). We view restoring habitat for pollinators
as a supplemental insurance policy one that
makes the most of marginal cropland by increasing biodiversity, he explains.
The challenge is finding native,
ecoregion-specific plant mixtures able to produce
a sequential bloom and therefore long-term
foraging habitat from spring through fall, and to
include plants that will not dominate the
landscape over time. Ideally, says Peters, at
least 15 farmers in each US region will be
recruited to the campaign, to establish best
management practices necessary to maintain these
mixtures. We want this program to flourish, he
continues, because agriculture and biodiversity can coexist.
