Why Do Native Pollinators Matter in New Hampshire Landscaping?
What are native pollinators in New Hampshire?
Native pollinators are the insects, birds, and other animals that evolved in a region and perform pollination services for local plants. In New Hampshire, this group includes a diverse set of bees (solitary mining bees, mason bees, bumblebees, sweat bees), butterflies and moths, flies such as syrphid hoverflies, beetles, and hummingbirds. Each of these taxa plays a different role in moving pollen, supporting plant reproduction, and maintaining habitat complexity.
Many of these species are specialists that require particular native plants or nesting substrates. That close ecological fit is why native pollinators are especially important for landscapes that aim to support local biodiversity and ecosystem function.
Bees: the workhorses
Native bees are the most efficient pollinators for many New Hampshire plants and crops. They outnumber honey bees in species diversity and include:
-
Ground-nesting bees (Andrena and many halictids) that nest in bare or sparsely vegetated soil.
-
Cavity-nesting bees (Osmia, Megachile) that use hollow stems, pithy canes, or wood cavities and are excellent early-season pollinators.
-
Bumblebees (Bombus spp.) that forage in cool, cloudy weather and are important for pollinating tomatoes, blueberries, and many native perennials.
Native bees provide services at low cost to the landscaper – they do not need hives, are active when local plants bloom, and often forage within short distances of their nests. Many native bees are more effective crop pollinators than managed honey bees because of traits such as buzz-pollination and longer tongues suited to certain flower shapes.
Butterflies, moths, hummingbirds, flies, and beetles
Butterflies and moths contribute to pollination while also depending on landscapes for host plants and nectar. Monarch butterflies rely on milkweed for larval development; several native swallowtails and fritillaries need specific trees and shrubs as caterpillar food.
Hummingbirds, particularly the ruby-throated hummingbird, are attracted to tubular native flowers like columbine and bee balm and provide pollination for those species.
Syrphid flies mimic bees in appearance and pollination function. Beetles and small flies are important pollinators for some native shrubs and early-blooming species. The diversity of pollinators ensures that a wide range of plant morphologies are serviced across the growing season.
Ecosystem services and local benefits
Native pollinators deliver multiple, measurable benefits in New Hampshire landscapes:
-
Pollination of native plants: Pollinators ensure seed set for wildflowers, shrubs, and trees that support food webs, soil stabilization, and native plant regeneration.
-
Agricultural production: Highbush blueberry, apples, raspberries, and many small fruits in New Hampshire rely on insect pollination. Native bees can significantly increase fruit set and quality.
-
Biodiversity support: Pollinators underpin food resources for birds and mammals. Native plants supported by pollinators provide nesting and cover.
-
Resilience and adaptation: Native pollinators are adapted to local climate, soil, and plant communities. Landscapes that support a diversity of native pollinators are more resilient to pests, diseases, and changing conditions.
-
Cultural and aesthetic values: Pollinator-friendly gardens offer seasonal interest, education opportunities, and a connection to New Hampshire’s natural heritage.
Designing a pollinator-friendly New Hampshire landscape
Thoughtful design maximizes the presence and effectiveness of native pollinators. The design approach should prioritize local plant communities, structural diversity, and seasonal continuity of resources.
Plant selection: native species and bloom sequence
Choose plants that are native to New England or the local ecoregion. Important species and general bloom timing include:
-
Early spring: Willows (Salix spp.), serviceberry (Amelanchier), native fruit tree blossoms, and early bulbs provide nectar and pollen when pollinators emerge.
-
Late spring to early summer: Wild columbine (Aquilegia canadensis), wild blueberry (Vaccinium angustifolium and V. corymbosum), highbush cranberry (Viburnum trilobum), and beardtongue (Penstemon).
-
Summer: Wild bergamot (Monarda fistulosa), beebalm (Monarda didyma), coneflowers (Echinacea spp.), black-eyed Susan (Rudbeckia hirta), and native phlox.
-
Late summer to fall: Goldenrods (Solidago spp.) and asters (Symphyotrichum spp.) are critical late-season nectar sources.
Plant in drifts or clusters rather than single specimens to make flowers more visible and energy-efficient for pollinators. Include a mix of flower shapes, colors, and heights to accommodate different tongue lengths and foraging behaviors.
Nesting and habitat features
A landscape that provides nesting opportunities will support resident pollinator populations:
-
Leave patches of bare or sparsely vegetated soil for ground-nesting bees. Avoid compacting these areas with heavy mulch.
-
Retain dead wood, logs, and standing snags for beetles, solitary bees, and cavity-nesting insects.
-
Preserve and plant pithy-stemmed natives (e.g., sumac, elderberry) or provide bundles of hollow stems for cavity-nesters.
-
Create brush piles and maintain leaf litter for overwintering insects and pupae.
-
Install bee hotels only as a supplement and follow best practices: use varied tunnel diameters, depth control to prevent parasites, and clean or replace tubes yearly to avoid disease buildup.
Water, shelter, and wintering
Provide shallow water sources with landing stones for bees and butterflies. Small saucers or birdbaths with pebbles work well. Maintain microhabitats: sunny glades, windbreaks, and undisturbed edges where pollinators can warm, forage, and find shelter.
Allow parts of the landscape to go untidy in late fall and winter. Many pollinators overwinter as larvae or adults in stems, leaf litter, and soil. Cutting back all vegetation in autumn removes these safe sites.
Maintenance, pesticides, and common pitfalls
Management practices can either help or harm native pollinators. Follow these guidelines:
-
Minimize or eliminate use of insecticides, especially systemic neonicotinoids. These chemicals can persist in soil and nectar and harm non-target pollinators.
-
If pesticides are necessary, use targeted applications, choose products with the lowest toxicity to pollinators, and apply at dusk or dawn when pollinators are less active.
-
Reduce lawn area in favor of native plantings. Lawns offer little for pollinators and require inputs that can be harmful.
-
Avoid excessive tidy-up in fall. Leave seed heads, stems, and leaf litter through winter.
-
Beware of “bee hotel” misuse. Poorly maintained hotels can concentrate parasites and pathogens. Clean, rotate, or replace nesting materials.
Practical checklist – ten actions to help native pollinators
-
Replace part of your lawn with native flowering plants and shrubs.
-
Plant interconnected patches of natives to create movement corridors.
-
Ensure continuous bloom from early spring through late fall with staggered plantings.
-
Provide bare soil patches and pithy stems for nesting.
-
Keep dead wood and brush piles as habitat features.
-
Supply a shallow water source with landing stones.
-
Avoid neonicotinoids and reduce broad-spectrum insecticide use.
-
Time any necessary pesticide applications for evening hours and spot-treat only.
-
Leave some plants and seedheads standing into winter.
-
Learn to identify key pollinators and monitor visits to adapt plant choices.
Monitoring, community involvement, and next steps
Homeowners and landscapers can contribute to broader conservation by monitoring pollinators and sharing observations. Simple actions include counting visitors on a patch of flowers, photographing species for identification, and tracking bloom windows. Neighborhood-scale actions – creating pollinator corridors along roads, parks, and yards – multiply benefits.
Local native plant nurseries, extension services, and community groups can help with species selection and propagation tips. Working with landscapers to include native plant palettes and pollinator-friendly practices in design can make new developments more wildlife friendly from the start.
Common mistakes to avoid
-
Relying solely on ornamental non-native plants that offer little pollen or nectar.
-
Clearing all “messy” elements like leaf litter and dead stems every fall.
-
Installing poorly designed bee hotels and then neglecting them.
-
Choosing plants based only on color without considering bloom time, form, or native provenance.
-
Assuming honey bees replace native pollinators – honey bees can compete with wild bees and do not pollinate all crops as effectively.
Conclusion – the long-term value of native pollinators in New Hampshire landscaping
Native pollinators are essential partners for healthy New Hampshire landscapes. They support native plant reproduction, enhance yields for local fruit crops, and sustain biodiversity. Designing landscapes that provide food, nesting sites, water, and shelter will increase pollinator numbers and diversity while delivering tangible benefits to gardeners, farmers, and communities.
Investing in native plants, adapting maintenance to support wildlife, and reducing pesticide reliance are concrete, practical steps any homeowner or land manager can take. Collectively, these steps create resilient neighborhoods and working landscapes that preserve New Hampshire’s natural heritage for future generations.
