In recent years we've become aware that Honeybees and Monarch Butterflies have suffered population declines due to various human activities. In response some organizations or individuals have tried to create habitat for pollinators within their properties. The chemicals that effect honeybees negatively have also been put under the microscope of the public's eye. The short version of this article is written to quickly broaden our perceptions and, perhaps, direct us in a productive path towards pollinator conservation.
Why do we care about pollinators?
If you care specifically about the production of honey, a product only attainable from the non-native Honeybee (Apis mellifera), there's no need to worry. As of this time, honeybee populations are stable, though colonies suffer from higher failure/death rates than in the past due to pathogens and parasitic insects. Our monoculture, weedless agricultural landscape of almond, apple, and cherry orchards can't support bees year-round, so these orchards are honeybee dependent by design not by necessity. This is to say, if we create habitat for our 4,000 species of Native Bees within our agricultural landscape, the honeybee is no longer necessary for it's pollination services. The convenience of being able to truck-transport honeybees from orchard to orchard enables these environments to be complete free of native plants that would support native bees and other pollinators on site for pollination. See the almond orchard picture below to see the system that creates portable honeybee hive dependency. Honeybees couldn't survive here either if they weren't trucked away afterwards, because there's nothing else to forage for after the Almond bloom peaks. They'd have to be fed corn syrup and sugar water to get by.
Why Should We Care About Native Pollinators?
Native bees account for over 50% of the insect pollination in our ecosystems. The plant diversity within our Desert, Grassland/Prairie, Savannas, Forests, and Wetland ecosystems is largely dependent on native pollinators which also includes flies, beetles, moths, butterflies and other species of insects. The remainder of the pollination is taken care of by the wind, which pollinates certain trees, shrubs, and grasses primarily. Since honeybees are non-native they are in no way necessary to the function of these ecosystems. While their negative effects haven't been thoroughly studied, resource competition and pathogen spreading from honeybees have indicated potential negative effects on native bee populations. See our extended version of this article for more details on negative impacts of honey bees on native bees. Without native plant diversity, we will see a further decline in biodiversity. Native pollinators help to ensure plant diversity through the pollination of plants that compete with wind-pollinated plants. To put it simply, loosing native pollinators would destroy the fabric of our ecosystems, which currently are the only terrestrial carbon sink mitigating climate change, improving water quality, improving air quality, and supporting the thousands of species that we exclude from our agricultural system.
What should I do, what should we do?
First, don't become a honeybee keeper, your passion and energy would be more productive doing some of the things we're about to recommend. Keeping honeybees cannot solve and in some ways may worsen the major issues with pollinator conservation. The decline of native bees and pollinators is primarily due to the destruction of our ecosystems (habitat loss), owed mostly to hundreds of millions of acres of agriculturally managed land. It isn't a farmer's fault entirely, our agricultural land is decided by what people demand/consume through diet choices and energy use but we'll save that for our next article. Further decline has happened as our rural and agricultural landscapes have become more intensively applied with herbicides that eliminate the wild plants our pollinator populations relied on. While invasive plants are now destroying the edge habitats which used to hold a high diversity of flowering plants where native pollinators could set up shop. Honeybees have actually been shown to increase the success of non-native invasive plants due to their willingness to pollinate them.
So what to do, what to do? Find ways to promote and support Indigenous Agroforestry.
Currently our agricultural system is based on annuals; corn, wheat, soybeans, and a few other crops which are all seed crops. Agroforestry replaces the annual seed crop system with perennial seed crops mostly in the form of tree nuts such as Pecans, Oaks, Chestnuts, Hickories, an Hazelnuts. These woody plants can be spaced out so their canopies don't touch allowing for smaller trees, shrubs, and herbaceous crops to be grown in between diversifying the agricultural landscape. Indigenous examples of the lower level plants would be Blackberries, Raspberries, Wild Plums, Serviceberry, Passionflower, Stinging Nettle, Groundnut, Grapes, Cut-leaf Coneflower, Jerusualem Artichoke, Evening Primrose, PawPaw, American Persimmon and many more. When agriculture shifts to an indigenous perennial system, soil is conserved, more carbon is sequestered in the soil and above ground, irrigation needs decrease, fertilizer needs decrease and biodiversity increases in response to the native plants. Since the plants are indigenous, it becomes "eco-inclusive", allowing all types of insects including pollinators, and higher life forms to co-exist. Compare this with our current agricultural system which is "eco-exclusive" primarily supporting one single species (humans). In fact, any food system that isn't based in indigenous plants is much more so eco-exclusive, as non-native plants lack the co-evolution with native insects and wildlife to support them.
When our agricultural system incorporates indigenous plants as the foundation, we no longer have to look at the hundreds of millions of acres of agricultural land as habitat loss in the way that we do today. This would also in part, mitigate what is called habitat fragmentation, by connecting perennial indigenous agroforestry land to existing undeveloped habitat. We would not need to talk about Monarch butterfly decline or pollinator decline if our Agricultural system would include them, instead of exclude them. Though this requires a shift in awareness of indigenous foods and diet choice by the people to support such a major transition.
Our Upcoming Workshops as Fundraisers for Indigenous Farm
Indigenous Landscapes is preparing to purchase a 12-15 acre piece of arable land locally, in the Cincinnati Region. This land will grow over 65 native species of food crops, over 30 native culinary and medicinal herb crops, while housing over 40 more native species of plants within a prairie for pollinator support on site. This amount of land will not produce a significant amount of food for the metropolitan, but it will instead serve as the source of indigenous foods for annual indigenous food festivals. These food festivals will be the way we promote indigenous Agroforestry to the public.
If you would like to support us in this conservation venture, please attend one or all of our upcoming workshops which have a $20.00 fundraising fee. Keep in contact with our Facebook Page or watch our Workshops page on our website to be sure you're registered once registration opens. The first workshop will be this March, focused on pollinator conservation. Your attendance will not only deliver you a high quality workshop, but 100% of the proceeds will go to funding the land purchase for this local indigenous plant farm, to be.
