Can native pollinators fill the gap?

Recently, ominous headlines have described a mysterious  ailment, colony collapse disorder (CCD), which is wiping out the honeybees  that pollinate many crops. Without honeybees, the story goes, fields will be  sterile, economies will collapse, and food will be scarce.

But what few accounts acknowledge is that what’s at  risk is not itself a natural state of affairs. For one thing, in the United  States, where CCD was first reported and has had its greatest impacts,  honeybees are not a native species. Pollination in modern agriculture isn’t  alchemy, it’s industry. The total number of hives involved in the U.S.  pollination industry has been somewhere between 2.5 million and 3 million in  recent years. Meanwhile, American farmers began using large quantities of organophosphate  insecticides, planted large-scale crop monocultures, and adopted “clean  farming” practices that scrubbed native vegetation from field margins and  roadsides. These practices killed many native bees outright — they’re as  vulnerable to insecticides as any agricultural pest — and made the  agricultural landscape inhospitable to those that remained. Concern about  these practices and their effects on pollinators isn’t new, in her 1962  ecological alarm cry Silent  Spring, Rachel Carson  warned of a ‘Fruitless Fall’ that could result from the disappearance of  insect pollinators.

If that ‘Fruitless Fall’ has not — yet — occurred, it  may be largely thanks to the honeybee, which farmers turned to as the ability  of wild pollinators to service crops declined. The honeybee has been semi-domesticated  since the time of the ancient Egyptians, but it wasn’t just familiarity that  determined this choice: the bees’ biology is in many ways suited to the kind of  agricultural system that was emerging. For example, honeybee hives can be  closed up and moved out of the way when pesticides are applied to a field.  The bees are generalist pollinators, so they can be used to pollinate many  different crops. And although they are not the most efficient pollinator of  every crop, honeybees have strength in numbers, with 20,000 to 100,000 bees  living in a single hive. “Without a doubt, if there was one bee you wanted  for agriculture, it would be the honeybee,” says Jim Cane, of the U.S.  Department of Agriculture. The honeybee, in other words, has become a crucial  cog in the modern system of industrial agriculture. That system delivers more  food, and more kinds of it, to more places, more cheaply than ever before.  But that system is also vulnerable, because making a farm field into the  photosynthetic equivalent of a factory floor, and pollination into a series  of continent-long assembly lines, also leaches out some of the resilience  characteristic of natural ecosystems.

Breno Freitas, an agronomist in Brazil, pointed out  that in nature such a high degree of specialization usually is a very  dangerous game: it works well while all the rest is in equilibrium, but runs quickly  to extinction at the least disbalance. In effect, by developing an  agricultural system that is heavily reliant on a single pollinator species,  we humans have become riskily overspecialised. And when the human-honeybee  relationship is disrupted, as it has been by colony collapse disorder, the vulnerability  of that agricultural system begins to become clear.

In fact, a few wild bees are already being successfully  managed for crop pollination. “The problem is trying to provide native bees  in adequate numbers on a reliable basis in a fairly short number of years in  order to service the crop,” Jim Cane says. “You’re talking millions of  flowers per acre in a two-to three-week time frame, or less, for a lot of  crops.” On the other hand, native bees can be much more efficient pollinators  of certain crops than honeybees, so you don’t need as many to do the job. For  example, about 750 blue orchard bees (Osmia lignaria) can pollinate a hectare  of apples or almonds, a task that would require roughly 50,000 to 150,000 honeybees.  There are bee tinkerers engaged in similar work in many corners of the world.  In Brazil, Breno Freitas has found that Centris tarsata, the native  pollinator of wild cashew, can survive in commercial cashew orchards if growers  provide a source of floral oils, such as by interplanting their cashew trees  with Caribbean cherry.

In certain places, native bees may already be doing  more than they’re getting credit for. Ecologist Rachael Winfree recently led  a team that looked at pollination of four summer crops (tomato, watermelon,  peppers, and muskmelon) at 29 farms in the region of New Jersey and  Pennsylvania.

Winfree’s team identified 54 species of wild bees that  visited these crops, and found that wild bees were the most important  pollinators in the system: even though managed honeybees were present on many  of the farms, wild bees were responsible for 62 percent of flower visits in  the study. In another study focusing specifically on watermelon, Winfree and  her colleagues calculated that native bees alone could provide sufficient  pollination at 90 percent of the 23 farms studied. By contrast, honeybees  alone could provide sufficient pollination at only 78 percent of farms.

“The region I work in is not typical of the way most  food is produced,” Winfree admits. In the

Delaware Valley, most farms and farm fields are  relatively small, each farmer typically grows a

variety of crops, and farms are interspersed with  suburbs and other types of land use which means there are opportunities for  homeowners to get involved in bee conservation, too. The landscape is a  bee-friendly patchwork that provides a variety of nesting habitat and floral  resources distributed among different kinds of crops, weedy field margins,  fallow fields, suburban neighborhoods, and semi natural habitat like old  woodlots, all at a relatively small scale. In other words, “pollinator  friendly” farming practices would not only aid pollination of agricultural  crops, but also serve as a key element in the over all conservation strategy  for wild pollinators, and often aid other wild species as well. Of course,  not all farmers will be able to implement all of these practices. And  researchers are suggesting a shift to a kind of polyglot agricultural system.  For some small-scale farms, native bees may indeed be all that’s needed. For  larger operations, a suite of managed bees — with honeybees filling the  generalist role and other, native bees pollinating specific crops — could be  augmented by free pollination services from resurgent wild pollinators. In  other words, they’re saying, we still have an opportunity to replace a risky  monoculture with something diverse, resilient, and robust.
