Benefits Of Native Shrubs For North Dakota Pollinators

Native shrubs are a high-impact, cost-effective element of any landscape, restoration project, or farm margin in North Dakota. They provide year-round benefits to pollinators and other wildlife by offering nectar, pollen, shelter, larval host plants, and fruit for food and seed dispersal. When chosen and managed correctly, native shrubs increase pollinator abundance, support species diversity (including specialist bees and lepidoptera), stabilize soil, and create resilient habitat corridors across fragmented prairie and agricultural lands.
Understanding the specific ecological roles shrubs play in the Northern Plains and applying practical planting strategies will make small properties and large-scale projects much more valuable to pollinators.

Why native shrubs matter for pollinators in North Dakota

Native shrubs co-evolved with local pollinators and herbivores. They flower at times when herbaceous plants are not yet in bloom or are past their peak, creating continuity of nectar and pollen resources across the season. Shrubs also produce berries and seeds that feed birds and small mammals, which in turn disperse seeds and maintain shrub populations.
Native shrubs do more than feed adult pollinators. They:

• Provide structural diversity for nesting, resting, and shelter from weather.
• Serve as larval hosts for moths and butterflies.
• Support specialist native bees that nest in stems, pithy wood, or nearby soil.
• Improve landscape connectivity by forming hedgerows and windbreaks.

These functions are especially important in North Dakota, where tallgrass and mixed-grass prairie fragmentation has reduced continuous habitat and where pollinators must find reliable resources across agricultural seasons.

Seasonal resource gaps and shrub value

Spring: Many solitary bees emerge early and need pollen and nectar before most forbs bloom. Shrubs such as willows and chokecherry bloom early and are critical spring forage.
Summer: Shrubs that bloom in mid-to-late summer support bumble bees, syrphid flies, and butterflies when prairie flowering can be variable under drought.
Fall: Fruit-bearing shrubs extend nutritional resources for migrating pollinators and seed-eating birds preparing for winter.

Best native shrubs for North Dakota pollinators

Below is a selection of North Dakota native shrubs that reliably support pollinators. For each shrub, I list the typical bloom period, primary pollinator visitors, and practical notes on siting and size.

• Chokecherry (Prunus virginiana) — Bloom: late April to May. Pollinators: bees, flies, butterflies. Notes: small tree/shrub, white racemes of flowers, important early-season pollen and host plant for some Lepidoptera. Fruits are eaten by birds.
• Serviceberry / Saskatoon (Amelanchier alnifolia) — Bloom: April to May. Pollinators: native bees, honey bees, flies. Notes: attractive spring flowers and edible berries; good for small yards and naturalized corridors.
• Buffaloberry (Shepherdia argentea) — Bloom: April to May. Pollinators: bees and flies. Notes: drought tolerant, produces red/orange berries that persist into winter and feed birds. Tolerates alkaline soils.
• Western Sand Cherry (Prunus besseyi) — Bloom: April to May. Pollinators: bees, butterflies. Notes: adapted to prairie soils and dry sites; produces small cherries valued by wildlife.
• Red-osier Dogwood (Cornus sericea) — Bloom: May to June. Pollinators: bees, beetles. Notes: wetland-friendly, provides summer fruit and dense winter cover for birds.
• Snowberry (Symphoricarpos albus) — Bloom: May to June. Pollinators: bees and flies. Notes: white berries persist after fall and provide winter interest and cover. Tolerant of shade and poor soils.
• Leadplant (Amorpha canescens) — Bloom: June to July. Pollinators: bees (including native bees). Notes: a leguminous subshrub that fixes nitrogen and provides late-spring to mid-summer blooms.
• Willow species (Salix spp.) — Bloom: very early spring (catkins). Pollinators: early-emerging bees and flies. Notes: critical early pollen source; many willow species are native to riparian zones and wetlands.
• Currant / Golden currant (Ribes aureum) — Bloom: April to May. Pollinators: bees and hummingbirds to a limited extent. Notes: fragrant flowers and edible berries.
• Smooth Sumac (Rhus glabra) — Bloom: mid-summer. Pollinators: bees and butterflies. Notes: forms clumps or colonies and provides fall color and fruits that birds use.

Each of these shrubs plays a slightly different role in the seasonal resource calendar and in structural habitat. Combining species with staggered bloom times maximizes benefit.

How shrubs support different pollinator groups

Shrubs feed and shelter a broad spectrum of pollinators. Practical pairings to consider:

• Early-spring solitary bees: Willows, chokecherry, and serviceberry provide pollen and nectar just when queens and early-emerging solitary bees need it.
• Bumble bees: Large, nectar-rich flowers and continuous bloom from shrubs like leadplant and sumac support bumble bee colonies through summer.
• Butterflies and moths: Prunus species and some dogwoods and willows act as larval host plants for caterpillars, while shrub flowers supply adult nectar.
• Specialist bees: Some native bees require specific nesting substrates (pithy stems, hollow stems, or nearby bare ground). Shrubs with pithy stems (e.g., elderberry, certain roses) or adjacent open soil improve nesting opportunities.

Practical planting and management tips

1. Choose shrubs that match your site conditions (soil type, moisture, sun exposure) and spacing needs. Most prairie shrubs prefer full sun and well-drained soil, but species like red-osier dogwood prefer moist soils.
2. Plant a sequence of shrubs that bloom from early spring through fall. Aim for overlapping bloom windows so pollinators always find resources.
3. Source true native stock from reputable native plant nurseries. Avoid cultivars selected only for ornamental traits that reduce nectar/pollen or change floral morphology.
4. Plant in groups. Pollinators find and use patches more efficiently when shrubs are clustered rather than single specimens scattered widely.
5. Minimize pesticide use. If pesticides are necessary, apply them at night when pollinators are inactive and avoid systemic insecticides that move into nectar and pollen.
6. Manage for structural diversity. Leave some dead stems standing through winter for cavity-nesting bees, and retain leaf litter and bare ground for ground-nesting species.
7. Prune at the right time. Prune spring-flowering shrubs immediately after bloom to avoid removing next year’s flower buds. For shrubs primarily valued for summer bloom, late winter pruning is acceptable.
8. Mulch and water conservatively at establishment. Many native shrubs are drought-adapted once established; overwatering can weaken root systems.
9. Protect young shrubs from heavy browsing with temporary fencing or tree guards in areas with deer or rabbit pressure.
10. Monitor and adapt. Observe pollinator visitation and shrub performance, and adjust species composition or maintenance practices accordingly.

Designing pollinator-friendly shrub plantings

Design should consider vertical structure, bloom succession, and connectivity:

• Use shrubs as backbone elements in hedgerows that connect remnant prairies, shelterbelts, and field margins.
• Combine shrubs with native perennial flowers and grasses to create layered habitats: groundcover, herbaceous forbs, shrubs, and occasional small trees.
• Place shrubs on the south and southeast sides of properties where they provide warm microclimates favored by many pollinators.
• Leave corridors 6-12 feet wide where possible to allow for dense shrubings that serve as travel routes and foraging patches.
• Integrate fruiting shrubs near bird-friendly areas to maximize seed dispersal and wildlife interactions.

Pitfalls to avoid

• Planting non-native ornamental cultivars with reduced forage value. Showy double flowers or sterile cultivars can provide little to no nectar or pollen.
• Using systemic neonicotinoid-treated stock. These chemicals can persist and affect pollinators that use pollen and nectar.
• Removing all dead wood and stems every season. Many native bees overwinter in hollow stems or in pithy wood; removing all plant debris eliminates key nesting sites.
• Failing to plan for mature size. Planting shrubs too close together or under utility lines leads to later removal and habitat loss.

Monitoring success and community benefits

Measure results with simple, repeatable steps: count pollinator visits to focal shrubs for five minutes during peak bloom, record species observed, and note nesting signs such as chewed stems or bee holes. Over multiple seasons you should see increased pollinator diversity and abundance.
Beyond direct pollinator benefits, native shrub plantings provide erosion control, improved soil health, windbreak protection for crops, and aesthetic value. They also form part of climate-resilient landscapes, buffering temperature and moisture extremes for both plants and pollinators.

Takeaways

• Native shrubs are keystone components of pollinator-friendly landscapes in North Dakota because they provide food, nesting habitat, and structural diversity across seasons.
• Choose a mix of early-, mid-, and late-season bloomers (e.g., willow, chokecherry, serviceberry, leadplant, sumac) to deliver continuous forage.
• Plant in groups, match species to site conditions, avoid pesticide use, and manage to retain dead stems and leaf litter for nesting.
• Small changes–adding a few native shrubs in windbreaks, field edges, or yards–scale up to meaningful landscape-level benefits for bees, butterflies, birds, and other wildlife.

Implementing these practices will make any North Dakota property more supportive of pollinators and more resilient ecologically, while providing tangible benefits for agriculture, biodiversity, and community enjoyment.
