Pacific Lowland Mixed Forest Province 3 Why support pollinators?

In t h e i r 1996 b o o k , Th e Fo r g o t t e n Po l l i n a t o r s , Buchmann and Nabhan estimated that animal pollinators are needed for the reproduction Farming feeds of 90% of flowering plants and one third of human food . Each of us “ depends on these industrious pollinators in a practical way to provide us with the wide range of foods we eat. In addition, pollinators are part of the intricate web that supports the biological diversity in natural ecosystems the world, and that helps sustain our quality of life.

Abundant and healthy populations of pollinators can improve set we must remember and quality, and increase fruit size. In farming situations this increases production per acre. In the wild, biodiversity increases and wildlife food sources increase. that pollinators Pumpkins, broccoli, squash, and cabbage are some of the crops raised in the Pacific Lowland Mixed Forest Province that rely on and native bees for . Domestic honey bees pollinate approximately are a critical $10 billion worth of crops in the U.S. each year.

Unfortunately, the numbers of both native pollinators and domesticated bee populations are declining. They are threatened by habitat loss, link in our food disease, and the excessive and inappropriate use of . The loss of commercial bees to (CCD) has highlighted how severe the issues of proper hive management are to reduce stresses caused systems. by disease, use, insufficient , and transportation practices. ” Currently, the pollination services that the commercial industry -- Paul Growald, provides are receiving much needed research and conservation resources. Co-Founder, The efforts to understand the threats to commercial bees should help us understand other pollinators and their roles in the environment as well. Pollinator partnership

It is imperative that we take immediate steps to help pollinator populations thrive. The beauty of the situation is that by supporting pollinators’ need for habitat, we support our own needs for food and support diversity in the natural world.

Thank you for taking time to consult this guide. By adding plants to your landscape that provide food and shelter for pollinators throughout their active seasons and by adopting pollinator friendly landscape practices, you can make a difference to both the pollinators and the people that rely on them.

20 Selecting Plants for Pollinators Habitat and Nesting requirements:

Bumble Bees: Abandoned mouse nests, other burrows, upside down flower pots, under boards, and other human-made cavities. Colonies are founded by a queen in the spring and don’t die out in the fall. New queens mate then and overwinter in a sort of hibernation. Bumble bees are usually active during the morning hours and forage at colder temperatures than honey bees, even flying in light rain.

Large carpenter bees: Soft dead wood, poplar, cottonwood or willow trunks and limbs, structural timbers including redwood. Depending on the species, there may be one or two brood cycles per year. These bees can be active all day even in the hottest weather.

Digger bees: Sandy soil, compacted soils, bank sides. Anthophorid bees (now in the ) are usually active in the morning hours, but can be seen at other times.

Small carpenter bees: Pithy stems including and blackberry canes. These bees are more active in the morning but can be found at other times. “ MONARCH Squash and Gourd bees: Sandy soil, may nest in gardens (where pumpkins, squash and gourds are grown) or BUTTERFLIES pathways. These bees are early risers and can be found in pumpkin patches before dawn. Males often sleep in the wilted flowers. NEVER FAIL TO Leafcutter bees: Pre-existing circular tunnels of various diameters in dead but sound wood created by emerging beetles, some nest in the ground. Leave dead limbs and trees to support not CATCH THE just pollinators but other wildlife. Leafcutter bees can be seen foraging throughout the day even in hot weather. VISITOR’S EYE Mason bees: Pre-existing tunnels, various diameters in dead wood made by emerging beetles, or AND ALWAYS human-made nesting substrates, drilled wood boards, paper soda straws inserted into cans attached to buildings. Mason bees are generally more active in the morning hours. LEAD TO Sweat bees: Bare ground, compacted soil, sunny areas not covered by vegetation. Like most bees, sweat bees forage for pollen earlier in the morning and then for nectar later. A TEACHABLE

Plasterer or cellophane bees: Bare ground, banks or cliffs. Colletid bees can be active in the morning or later in the day. MOMENT.” Yellow-faced bees: -- LOGAN LEE, In dead stems. These bees are more active during morning hours. PRAIRIE SUPERVISOR Andrenid bees: Sunny, bare ground, sand soil, under leaf litter or in soil in banksides and cliffs. These MIDEWIN NATIONAL generally spring-active bees are most commonly seen on flowers during the morning when pollen and nectar resources are abundant. TALLGRASS PRAIRIE

Pacific Lowland Mixed Forest Province 21 A Basic Checklist

Become familiar with pollinators in your landscape.

n Watch for activity throughout the day and the seasons. n Keep a simple notebook of when and what comes to your garden. NOTE: It is not necessary to identify each species when you first get started. Simply note if it is a bee that likes the yellow flower that blooms in the fall. n Consult a local field guide or web site when you are ready to learn more details.

Add native plants to attract more native pollinators.

n List the plants you currently have in your landscape. n Determine when you need additional flowers to provide nectar and pollen throughout the growing season. n Add plants that provide additional seasons of bloom, create variable heights for shelter, and attract the types of pollinators you want. n Don’t forget to include host plants that provide food and shelter for larval development. n Contact your local native plant society or extension agent for more help.

Use pollinator friendly landscape practices to support the pollinators you attract.

n Use Integrated Pest Management Practices to address pest concerns. n Tolerate a little mess – leave dead snags and leaf litter, keep areas bare for ground nesting insects, and leave some weeds that provide food for pollinators. n Provide safe access to clean water.
