Why is plant diversity important for pollinator health, and name one plant group that supports native pollinators in Wisconsin.

• A. It helps support non-pollinator insects by providing habitat.
• B. It increases competition for resources; plant group: invasive grasses.
• C. It provides a range of nectar and pollen across seasons and reduces reliance on one species; a plant group: native wildflowers such as goldenrod, milkweed, and asters.
• D. It has no impact on pollinators; plant group: synthetic annuals.

Answer: (C)

Diverse plantings provide a steady buffet of nectar and pollen across the growing season, which keeps pollinators energized and able to reproduce. When bloom times are spread out and plants offer different nectar/pollen rewards, a variety of pollinators—from bees to butterflies to moths—find what they need without having to rely on a single species. This reduces the risk that bad weather, pests, or disease wiping out one plant will leave pollinators without food.

In Wisconsin, native wildflowers are especially supportive because they’re adapted to local soils, climates, and pollinator communities, offering reliable resources throughout the season. Native wildflowers like goldenrod, milkweed, and asters provide nectar and pollen at different times, sustaining pollinators from spring through late fall. Milkweed is particularly important for monarchs, while goldenrod and asters help supply late-season nectar.
