Four Simple Steps – Pollinators

Bumblebee on Virginia Waterleaf (Hydrophyllum virginianum). Recent declines in pollinators have alarmed scientists and naturalists alike. Pollinators include not only bees, but also birds, butterflies, bats, beetles and more.

National Pollinator Week, initiated and managed by Pollinator Partnership, is a time to celebrate pollinators and spread the word about what we can do to protect them.

Thirteen years ago, the U.S. Senate unanimously approved the designation of a week in June as “National Pollinator Week.” S.Res. 580 (109th Congress) reads: A resolution recognizing the importance of pollinators to ecosystem health and agriculture in the United States and the value of partnership efforts to increase awareness about pollinators and support for protecting and sustaining pollinators by designating June 24 through June 30, 2007 as “National Pollinator Week.” (GovTrack)

Four Simple Steps

It’s so simple to bring “back the pollinators” with only these four simple steps – Pollinator Protection Pledge:

  1. Growing pollinator-friendly flowers.
  2. Providing nest sites.
  3. Avoiding pesticides.
  4. Spreading the word.

Million Pollinator Garden Challenge

The National Pollinator Garden Network surpassed our goal to meet the Million Pollinator Garden Challenge. So far, 1,057,008 gardens and landscapes have been registered.

Useful info from the Million Pollinator Garden Network:

  • Use plants that provide nectar and pollen.
  • Provide a water source.
  • Situate the gardens in sunny areas with wind breaks.
  • Create large “pollinator targets” (clumps) of native or non-invasive plants.
  • Plant a variety of plants that bloom throughout the growing season.*
  • Eliminate or minimize the impact of pesticides.
  • Leave a dead tree or tree limb to create bee habitat.
  • Include plants that bloom at night to attract bats and moths.
  • Use the Pollinator Partnership regional planting guides to help you determine the plants most appropriate for your area. Enter your zip code to find suggestions for your pollinator garden.

*Choose plants native to your ecoregion. They will have evolved with the local biodiversity and will be most appropriate for the local pollinator species.

We know that more nectar and pollen sources provided by more flowering plants and trees help improve pollinators’ health and numbers. Increasing the number of pollinator-friendly gardens and landscapes will help revive the health of bees, butterflies, birds, bats and more across the country.

It’s Pollinator Week!

This week, June 22-28, 2020, is when we celebrate pollinators. This is the week we celebrate the special species in our lives – the bees, birds, butterflies, bats and beetles. It is a special time to pause, celebrate pollinators and focus on what we can do to help pollinators thrive in this world of global climate change and global warming.

Ecosystems

It all starts with ecosystems. The Earth is made up of naturally occurring geographical areas with similar climate, geology and soils. Typically, within each of these ecoregions, there are a number of ecological regions referred to as ecosystems made up of plants, animals, birds, butterflies, insects, organisms and the physical environment or habitat in which they live. Typically, all these elements in the ecosystem develop a mutually dependent relationship that becomes a Circle of Life.

Pollination and the Circle of Life

Pollination is a very important element in the Circle of Life. Why? Because the Circle of Life starts with plants, and most plants depend upon pollination to reproduce.

  • Plants absorb sunlight energy through photosynthesis – solar power.
  • They use that energy to produce more plant material from water, carbon dioxide in the air, and nutrients from the soil.
  • In the process, they give off oxygen – thank goodness.
  • Herbivores (primary consumers) eat the plants and use the nutrients to produce more herbivores.
  • Predators (secondary consumers ) eat the herbivores and use the nutrients to produce more carnivores.
  • When death comes, a vast suite of soil organisms (bacteria and fungi) decompose the material, returning the nutrients to the soil.
  • This makes the nutrients available for plants to take up again, completing the Circle of Life.

Pollination is a reproductive process. Flowers offer food (nectar) to pollinators in exchange for reproduction. It occurs when pollen is transferred from the anther (male part of flower) to the stigma (female part of flower). And, it’s very important, because without pollination, we would not have vegetables and fruits to eat, and plants could not reproduce from season to season.

What Role Do Pollinators Play?

Although some pollen is dispersed by the wind, birds, butterflies, bees and other insects and animals are the main transporters of pollen between flowers, hence the term pollinators. They carry the pollen, which is a fine powdery dust found in the male part of the plant (anther) and contains the plant’s sperm, to the female part of the plant (stigma). Some pollinators have special structures by which they carry the pollen – like the native bees. Others, such as butterflies, bats and other insects carry the pollen from one flower to another when it affixes itself to their bodies, legs and wings.

Gardening for Pollinators

Flowers and pollinators co-evolved, developing features that make the exchange of pollen and nectar successful. To support native pollinators, we need to grow the native plants with which they evolved. Because they evolved together, native plants have the “right” features. Here are some examples.

Native habitat is disappearing rapidly as fencerows are being destroyed for crop farming, and land is being developed for residential, commercial and manufacturing use.* It is important to support pollinators by growing native plants to provide nectar and pollen throughout the seasons, and to make sure host plants are included that provide food and shelter for larval development. It is also important to provide access to clean water and to create variable heights for shelter and nesting. Most importantly, use insecticides sparingly, if at all.

Last, tolerate a little mess – leave dead snags and leaf litter, keep some areas bare for ground-nesting insects, and tolerate non-noxious, non-invasive weeds that provide food and shelter for pollinators.

*According to Doug Tallamy in the film Hometown Habitat, only 5 percent of our land remains as native habitat. 42 percent is being used for crop framing, and 53 percent for development.

Why Do Bees Dance?

In their search for food, honeybees and bumblebees fly far and wide searching for the best flowers (loaded with nectar) – and when a bee finds what she’s looking for, she returns to the hive to share her find with the other bees by performing a complicated “dance.”

WAGGLE DANCE

Why do the bees dance? In the 1940s, Austrian biologist, Karl Von Frisch, devised an experiment to find out. When the bee arrives back at the hive, she draws the attention of the other bees, and begins moving her body, especially vibrating her abdomen, in a specific set of movements. This “dance” resembles a figure eight as she moves back and forth, over and over. The duration of her dance indicates how far away the flowers are, and she indicates the direction to the flowers by the angle of her dance related to the sun. (The Waggle Dance of the Honeybee)

STOP SIGNAL

Honeybees also can warn their nest mates about dangers they have encountered. If a bee is doing the waggle dance, another bee who had previously encountered danger (such as a wasp or spider) at the location being “described” by the waggling bee, will often approach the dancing bee and butt her head against the dancer to cause a momentary “freeze” – which is seen as a warning by the other bees.

“S” Is for Soil!

A friend helping me with the blog has written a review of “S” Is for Soil!. In the book and the companion teacher’s guide, Digging into Soil: A Garden Practicum, we are to encouraged to see a perception of soil as a limitless resource. It is the most important natural resource on Earth. I read the book, and it was a good place to look – the soil beneath our feet.

By Kristin Kauth

I recently read and highly recommend the new book, “S” Is for Soil!, by ecologist Steven I. Apfelbaum, founder of Applied Ecological Services, Inc. The book explores the importance of soil to all life on Earth.

Only 38 pages long, the book is written for the layperson and includes an easy-to-read narrative on a complex subject. The whimsical graphics by Rob Dunlavey kept me smiling with the turn of every page, and I found the book both educational and delightful.

“S” Is for Soil! is divided into two sections:

  • The Basics – What Is Soil? (Don’t Call It Dirt) and
  • Expanded Understanding – Digging a Little Deeper (Whole System Thinking).

I can’t do better than the press release, so here are some excerpts:

As this simple primer begins, “…It has been said that we know more about the moon than the soil under our feet.” Today, with growing concern for dwindling resources, there is a new sense of urgency to better understand and care for soil (what many of us misguidedly call “dirt”) and our very real connection to it. In fact, “our lives may depend on it.”

Written for high school and older students, and lay, business, and professional audiences, “S” Is for Soil! and its cast of soil characters guides readers with clarity and humor through the essential and often complex understandings of soil, employing a conversational narrative. The book reveals the remarkable story of the abundance of life – from billions of microscopic organisms to burrowing animals – that occupies the thin layer of soil on the planet, and that represents 95 percent of all terrestrial life on Earth.

It explains the role healthy soil can play in addressing the challenging problem of climate change.

    played in storing large quantities of carbon deep in the ground – think of bison moving quickly over landscapes until it recovered.

  • Other soil-building practices like adding organic fertilizers, and innovative ranching and farming practices that are now being employed to “regenerate” or build-back soil health.
  • Building back to wetlands and the crucial role soil plays in the water cycle, and its importance in keeping our water supply clean.
  • By the putting all those “unemployed” soil microbes and deep-rooted grasses back to work, we help rebuild the lost carbon stores of the past and maintain healthy soil.

“S” Is for Soil! was produced in partnership with the Lower Sugar River Watershed Association (LSRWA). The book can be purchased individually or in larger discounted quantities online at LSRWA or by contacting at 608-897-8641.

A companion teacher’s guide titled Digging into Soil: A Garden Practicum has been created by KidsGardening in cooperation with the authors and LSRWA. It is available to download.
