National Pollinator Week and the Oregon Bee Project

For the past ten years, National Pollinator Week has provided a unique occasion for education, outreach and activity around pollinators. It is no coincidence that this annual celebration was established or that it has grown into the anticipated fixture on the summer calendar that it is today. In fact, the origins of Pollinator Week stretch back further than its proclamation by the US Senate in 2006.

In the late 1990s, an organization called Pollinator Partnership began linking together all the pieces around pollinator health and recognized that any meaningful national strategy would have to engage a broad spectrum of people; from growers, to consumers, from concerned citizens, to government agencies. Broad engagement, they determined, was necessary from the fact that insect pollinators are deeply interwoven into both natural and agricultural systems, and as such, are affected and influenced by a wide range people doing a variety of different activities during their busy lives.

There have been considerable changes in the way Americans relate to pollinators since the first National Pollinator Week. In fact, it might be difficult to fully understand the need for something like the Oregon Bee Project without taking stock of the ten years, or more specifically, two events that occurred that have strongly conditioned how we come to think about pollinators.

  • The first event that has definitely shaped how Americans think about pollinators occurred during the very first National Pollinator week in 2007. In that year U.S. beekeepers were discovering a new and yet explained syndrome facing their hive, Colony Collapse Disorder (CCD). Although the symptoms of CCD grew less prominent in subsequent years, the U.S. beekeeping industry, to this day, continues to face historically elevated levels of colony death which now appear to be the result of a combination of parasites and new diseases, reduced forage for colonies and pesticide exposure.
  • The second event occurred here in Oregon and it brought attention to the issue of native bees and pesticides. During the sixth National Pollinator Week bumble bees were killed by the improper application of insecticide applied to shade trees in a suburban Portland parking lot. The incident became a national news story and prompted calls for action around pesticide education and outreach.

These two events led to a response from both the Federal government and the Oregon Legislature. From the US Government there was the 2016 Pollinator Partnership Action Plan, which outlined a strategy to reduce honey bee colony losses and establish targets for building habitat for pollinators. Included in the federal approach were new guidelines for the Environmental Protection Agency to reduce pesticide exposure to pollinators through voluntary state-led Managed Pollinator Protection Plans (MP3s). In 2015, a Pollinator Health Task Force, commissioned by the Oregon Legislature, identified the need for better outreach and education around pesticides and pollinator to both traditional licensed pesticide applicators, but also unlicensed applicators, including home-owners.

What this means for the Oregon Bee Project: 

As we are busy learning, thinking, and celebrating National Pollinator Week in 2017, it’s a good time to think about the Oregon Bee Project and where it might be headed. In the short term, the Oregon Bee Project will be changing its scope in order to meet the mandates set by the Oregon Legislature and the Federal government and to work at a broader, more inclusive scale. Throughout 2017 Oregon State University and Oregon Department of Agriculture have been talking to all of you and using these conversations to outline a general strategy to coordinate state-level efforts on pollinator health around all these issues. We hope to get the details of this plan out to you early in the fall, but what this will ultimately mean is more partners and better footing for the Oregon Bee Project.

The Oregon Bee Project starts from the idea that pollinator health ultimately depends on the innovativeness of landowners, growers, homeowners and pesticide applicators and that this innovation is limited primarily by the absence resources, local networks, and science-based education, outreach and engagement. The Project is ultimately premised on the original vision of Pollinator Partnership that originally set the state for National Pollinator Week. As the Oregon Bee Project looks ahead to the second decade of National Pollinator Week it remains focused on developing practical tools for all Oregonians, drawing on the experience of the people who regularly work with and around bees, to keep Oregon bee-friendly.

Nesting Stations in Washington County

By Ron Spendal, OSU Extension Master Gardener

For the past 13 years I have been studying native pollinators in Washington county. I have eleven project sites across the county. Four of the sites are public venues like Jackson Bottom Wetlands and Jenkins Estate. The other seven sites are private farms. I also have three projects at three Hillsboro elementary schools where I teach second graders about pollination and mason bees. Each school has a mason bee nesting station and the second graders monitor and record the mason bee nesting activity.

I began my study of the mason bee using drilled nesting blocks but was quickly frustrated because I wanted to know what was happening inside of the blocks. I began making my own nesting devices and over time I have settled on making poplar nesting trays with five routed nesting channels that are 5/16 of an inch in diameter. All of my trays have clear plexiglass lids taped on them so I can see the bees building nests. I can see and photograph the bees laying eggs, the larval development, and the subsequent cocooning. I distribute and monitor approximately 500 nesting trays each season. Last year I harvested just under 20,000 mason bee cocoons. Many other native pollinators also nest in these trays. To see what other native pollinators might be at my sites I made several nesting trays that have nesting channels ranging from 1/8 inch diameter to ½ inch diameter.

A number of native pollinators used all of these trays so I began recording what species showed up and when. I have had several types of Osmia nest in the trays as well as other species of bees and wasps.  The blue orchard bee, commonly just called the mason bee, is generally the earliest bee to show up in the spring (early to mid April). Osmia cornifrons, the hornfaced  mason bee, follows soon after (mid to late April) then the Osmia caerulescens, the blue mason bee, follows (mid to late May). The small passaloecus wasp, the aphid wasp, comes next (early June) and prefers a channel diameter of 1/8 inch although it uses tree sap to reduce the entrance diameter to 1/16 of an inch.  This wasp preys on aphids.   Another wasp shows up at about the same time. It is Isodontia elegans, the grass carrying wasp. This beautiful wasp preys on drumming katydids and snowy tree crickets and builds nesting cells in 5/16 inch channels using grass clippings to make the cells. Anthidium manicatum ,the wool carder bee, shows up about the same time and builds fascinating cotton like tubes in the nesting channels. Many varieties of resin bees show up in early July and build nesting cells from all sorts of tree saps. Megachile angelarum uses beautiful ruby red sap to make its nesting cells. Other resin bees use black, green white and clear resins often mixed with sand particles or vegetation. In late June to early July Osmia Aglaia, the berry bee, and Osmia kinkaidii appear.  The berry bee is a brilliant green color. Megachile rotundata, the alfalfa leaf cutter bee, and Megachile, the sunflower bee appear in mid to late July. Other lesser known species of bees and wasps also make use of the nesting trays. Basically the trays are nested in from early April through late September. Since all of the bees and wasps nesting in the trays are solitary, they are all docile and easily viewed and managed.

Bee watching can be an engaging hobby. Using plastic lidded nesting trays allows you to have total access to the goings-on of a wide range of bees and wasps. They provide excellent opportunities to use in educating children and others on the nesting behaviors of native pollinators. Anyone who wants to explore these opportunities can conduct a number of citizen scientist projects and data collection. The bottom line is: build it and they will come!
