1. Humming for Bees February 24, 2014

2. Humming for Bees Colony Collapse Disorder (CCD) and the 4 P’s Solutions and Proposal Cost Considerations Resources Humming for Bees

3. Colony Collapse Disorder (CCD) In the United States and Europe bee colonies have experienced significant losses This phenomenon has become known as Colony Collapse Disorder or CCD There is significant concern as pollination has a very important role in our food production There are several contributors to CCD sometimes referred to as the 4 P’s Humming for Bees

4. The 4 P’s Poor Nutrition Pesticides Parasites Pathogens Humming for Bees

5. Poor Nutrition Not enough Bee Food Not enough plant variety Inconsistent food supply over entire foraging season Lawn monoculture = food desert “Weeds”, including flowering varieties, public and private, are mowed, weed-whipped and/or sprayed with poison. Humming for Bees

6. Pesticides Starting in around 2006 there has been increasing use of a family of pesticides know as “neonicotinoids” In heavy doses neonicotinoids, or neonics, are known to kill bees and other beneficial pollinators In lesser doses neonics are known to “disrupt bees’ reproduction, mobility, navigation, feeding, foraging, memory, learning, and overall hive activity” These neonicotinoids are systemic. All parts of the plant, roots, stem, leaf, pollen, nectar, and surrounding soil contain the chemical thus turning the plant into a poison factory. Humming for Bees

7. Pesticides (cont.) In some cases various pesticides (i.e. insecticides, herbicides, and fungicides) build up in bees, create problems due to the chemical combinations, and further weaken the bees Some countries have banned the use of neonicotinoids. In the USA our EPA has been granting conditional registration of neonicotinoids with incomplete health and safety data, and then extending that registration without required studies. Presently the EPA’s main action is facilitating labeling changes and providing guidance for investigation of “beekill” incidents The EPA estimated it will be 2018 before it makes a decision on neonicotinoids. Bees can’t wait 5 years! Humming for Bees

8. Pesticides (cont.) Bottom Line Don’t spray, drench, or inject bee-killing pesticides (i.e. No insecticides, herbicides and fungicides on or near Bee Food) Humming for Bees

9. Parasites and Pathogens There are a variety of parasites and pathogens that exist in honeybee populations Weaknesses due to lack of nutrition make bees more susceptible to pathogens (i.e. viruses) and they more readily succumb to parasites Weaknesses due to chronic and low levels of exposure to chemicals also make bees more susceptible to pathogens and parasites Humming for Bees

10. Humming for Bees Solutions and Proposal Humming for Bees

11. Solutions and Proposal Turn public spaces into Bee-Safe areas! Plant Pesticide-free flowers. Flowers are Bee Food! Don’t spray the Bee Food! (not on it, not near it) Educate all citizens regarding bees: their gifts and needs Begin this spring to implement the Bee Safe City Resolution Publish a “Bee Safe City Report” each spring Humming for Bees

12. Turn Public Spaces into Bee-Safe Areas Buy plants, shrubs, and trees from nurseries that guarantee they have not used neonicotinoids or other systemics on their seeds, plants, or trees. Utilize knowledgeable landscapers, gardeners and citizens who understand the issues Create Bee-Safe areas and plantings in public green spaces Humming for Bees

13. Plant Pesticide-free Flowers: Bee Food Plant a variety of flowering plants that bees like (pollen for protein, nectar for carbs) Plant a variety of flowering plants that guarantee blooming from spring to fall (April through October) Bees need to eat from pesticide-free plants, shrubs, and trees Humming for Bees

14. Don’t Spray the Bee Food No harmful pesticides (i.e. NO insecticides, herbicides, or fungicides on or near the bee food) Use IPM (Integrated Pest Management) best practices – systemic pesticides are not consistent with IPM Systemic pesticides are un-avoidable for bees and other foraging insects Humming for Bees

15. Educate the Public Tell the public what bees and pollinators are facing Tell the public what the cost of losing bees would mean to humans Show them the research by the Xerces Society, the Pesticide Action Network, our own U of M Bee Squad and the alarms that many others are sounding Ask them to see things with different eyes – perhaps the green lawn with its tons of upkeep, no flowering plants and no food for our bees is not the ideal after all. Humming for Bees

16. Cost Considerations Instead of spending $$ spraying for weeds, buy bee-favorite-food plants (garden & native species) Instead of spending $$ mowing the grass every week or two in public spaces, use that money on pesticide-free plants, shrubs and trees that provide nectar and pollen for bees Once established, many perennial garden and native plantings can be sustainable and may cost less to manage Humming for Bees
