Pollinator conservation
Apr 14, 2023
By Kwiaht
Maintaining pollinator services on Lopez is all about protecting nesting habitat for our wild bees, and avoiding the use of pesticides - not importing more domestic bees.
At Kwiaht we receive a lot of questions each year about bees and other pollinators in the islands. This year, with support from the San Juan Island Community Foundation, we have published a series of one-sheet briefing papers on recognizing wild native bees and inviting them to nest in your garden. We have also prepared two self-explanatory slideshows on the islands’ wild native pollinators, and how they are adapting how climate change: the cooler, wetter and windier early spring weather pattern that so often coincides with the first flush of cherries, plums, and native flowering currants. These publications and slideshows are free to download and to share.
Six key takeaways from our research, and research elsewhere on wild pollinators:
1. In the islands, we have inherited a diverse wild native pollinator community that includes at least 91 species of bees and more than a hundred species of “flower flies†or “hoverfliesâ€. Most of our wild bees are “solitary†and make simple individual nest tunnels in undisturbed ground.
2. Most wildlands and gardens in the islands are still pollinated mainly, if not exclusively, by wild native bees and flies. Nationwide, honeybees are only needed for the pollination of large-scale monocultures, especially in areas where mechanical cultivation, pesticides and herbicides have already degraded wild pollinator communities.
3. As our regional climate shifts to stormier winters and drier summers, we expect that native flies will account for a greater proportion of pollinator services, especially in early spring.
4. Commercially available domestic bees such as honeybees are unnecessary for maintaining pollinator services in the San Juan Islands. There is growing evidence that they displace native pollinators, and can spread viral diseases that kill native pollinators, such as Deformed Wing Virus.
5. Honeybees in particular require housing and feeding, while wild native bees only require appropriate places to build their nests such as rockpiles, rockery walls, brushy uncultivated patches, and hedgerows. Inviting native bees to nest inside your garden is the most economical and sustainable way to maintain pollinator services in the future.
6. The greatest threat to wild native pollinators in the San Juan Islands is the application of pesticides to buds, flowers, and soils, which poisons pollen and can infiltrate ground nests of bees. Pesticide sprays on aphid infestations kill flower-fly larvae that eat aphids, like ladybugs. Pesticide-contaminated insects are also a threat to the islands’ bats, which play a major role in suppressing moths and other garden pests.
