Pollinators such as bees, butterflies, flies, and hummingbirds play a key role in supporting plant diversity and maintaining healthy ecosystems, according to the Marin Master Gardeners. Over 80 percent of the world’s flowering plants depend on pollinators for reproduction. This includes wildflowers and many native species that contribute to air, soil, and water quality.
While wind, rain, birds, and bats can act as pollinators, insects like bees and wasps are especially important. The United States is home to about 3,600 native bee species. Most of these are solitary bees; females build their own nests and collect pollen using specialized hairs. Honeybees often seek out brightly colored flowers with sweet scents.
Bumble bees use a method called buzz pollination by vibrating their wing muscles to release pollen from certain flowers. This process benefits crops such as tomatoes and peppers.
Butterflies and moths also contribute to pollination. Some are generalists visiting various plants, while others require specific habitats. They prefer broad-faced flowers where they can land before feeding on nectar with their straw-like mouthparts.
Hummingbirds have long beaks suited for reaching deep into flowers for pollen and nectar, favoring bright colors like red.
Flies rank second only to bees in pollination importance due to their adaptability in harsh weather when bees remain inactive. Flies visit a variety of plants—including those with unpleasant odors—and transfer pollen as they feed on nectar.
Gardeners can support local pollinator populations by planting diverse flowers that bloom throughout the year and by prioritizing native species such as Milkweed, Poppies, and Asters. Other recommendations include practicing Integrated Pest Management (IPM) to limit chemical exposure for pollinators and providing water sources through birdbaths or shallow dishes.
The Marin Master Gardeners offer resources about pollinators on their website and in their newsletter. They will host a Pollinator Plant Sale on Saturday, March 7 from 9 AM to 12 PM outside the Falkirk Green House in San Rafael. The event will feature more than thirty-five types of organically grown plants suitable for local pollinators—including five hundred Narrow Leaf Milkweed plants for monarch caterpillars—as well as “Bug Hotels” for children.
UC Agriculture and Natural Resources (UC ANR), which shares science-based practices across California communities through research and outreach initiatives according to its official website, maintains nine Research and Extension Centers across diverse ecosystems and operates offices in all 58 counties. UC ANR is affiliated with the University of California and has provided resources in nutrition, food networks, environmental conservation, wildfire protection, and youth education for over a century as stated on its website. Glenda Humiston serves as vice president of UC Agriculture and Natural Resources according to the official site.
“Bug Hotels” will be available to purchase for the kiddos to decorate.
