Four at-risk species of wild bees are overdue for listing under SARA
Buzzing along, providing essential pollination services for both wild plants and cultivated crops, wild bees fulfill many important functions necessary to ensuring we have healthy ecosystems and flourishing agricultural economies. Unfortunately in recent years, we have seen a steep decline in the wild bee populations we depend on so much.
Honeybees are often the species most associated with dwindling bee numbers — in the winter of 2013-14, Ontario beekeepers lost 58 per cent of the province’s honeybee population — but what people may not know is that the honeybee is not alone. Many other bee species are in decline as well, and some have become threatened or endangered. The Gypsy Cuckoo Bumble Bee, Western Bumble Bee occidentalis and mckayi subspecies, and Macropis Cuckoo Bee have all been recommended for listing under the Species at Risk Act (SARA) by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC).
Unfortunately, when it comes to protecting these important wild pollinators, the federal government has not lived up to its responsibilities under SARA. Since COSEWIC first supplied its assessments to the Minister of Environment last year, no steps have been taken to add these four bee species to the List of Wildlife Species at Risk — no species receives any protection under SARA until it has been added to the List.
That’s why Ecojustice lawyers — on behalf of the Wilderness Committee, David Suzuki Foundation, Equiterre, Friends of the Earth and Ontario Nature — sent a letter to the Minister today, urging her to act now to protect the bees:
The federal government’s inaction leaves these bees vulnerable in the face of growing threats to their survival and recovery.
One particularly dangerous threat is the increasing use of bee-killing pesticides, called neonicotinoids or “neonics” for short. In 2012, Health Canada confirmed the link between the high number of bee deaths and the use of neonics on corn seed. Since then, the evidence of neonics’ lethal and chronic effects (including impairing natural forging behaviour) on pollinator species has continued to mount.
Scientific studies have also linked these pesticides to a wide range of harmful effects on other important species, including birds, butterflies, and earthworms.
Although the Ontario government has restricted the use of neonics on soy and corn seeds, Ontario’s regulation does not help the wild bee populations in provinces outside of Ontario where there are no limits on the use of neonics in place.
And of course, neonics are not the only threat that wild bee populations face. Disease, habitat loss, pests, and increasingly, climate change also endanger their survival and recovery.
They may be tiny, but wild bees are part of a critical network of pollinators vital to the functioning of our ecosystems and agricultural systems — when it comes to their pollination services, wild pollinators generally outperform honeybees. One study found that crops pollinated by wild pollinators resulted in higher yields than ones that had been pollinated by honeybees. Wild pollinators can also pollinate some plant species that honeybees are unable to pollinate.
We cannot afford to stand by while these fundamental species continue to die off. And we can’t afford to let the federal government continue to stand by, either.
