Overview

About This Region

The Mid-Boreal Uplands and Peac-Wabaska Lowlands, characterized by coniferous forests, peatlands, and wetlands, offer crucial habitat for numerous pollinators. However, these species face threats from habitat fragmentation due to resource extraction and agricultural expansion. Climate change is altering bloom times and species distributions, disrupting essential pollinator-plant synchronization. Conservation efforts in this region must focus on mitigating these impacts and preserving diverse flowering plant communities to support healthy pollinator populations.

What shapes this region

Climate pattern

  • Strong seasonality: a short warm season and a long cold season are typical.
  • “Microclimate” (small local weather differences) matters a lot—south-facing slopes, sheltered yards, and forest edges can behave very differently from open lowlands.
  • Wet lowlands can stay cooler and wetter; uplands and sandy/gravelly spots can be warmer and better drained.

Why pollinators matter here

  • Pollinators help many native flowering plants reproduce, supporting food webs.
  • Short growing seasons make timing important: early and late blooms can be especially valuable.
  • Sunny edges can act like “pollinator highways,” linking flowers and nesting sites.
  • Diverse native plantings can help stabilize nectar and pollen availability when weather swings from year to year.

Seasonal timing

Planting seasons

Timing varies by microclimate; use this as a flexible guide.

Seasonal timing

  • Spring: Good for planting hardy natives and starting small patches once soils are workable.
  • Summer: Focus on watering new plants, adding mulch carefully, and filling bloom gaps with summer-flowering natives.
  • Late summer/fall: Often a strong time for planting perennials and sowing some native seeds for natural cold-stratification (where appropriate).
  • Winter: Plan your patch, choose plants, and leave stems/leaf litter for overwintering insects.

Quick seasonal checklist

  • Pick a sunny spot (6+ hours is a common goal, but “more sun = more blooms” is the simple rule).
  • Plant in clusters (3–7 of the same plant) so pollinators can find them.
  • Ensure something blooms early, mid, and late.
  • Add nesting habitat: bare soil, stems, and a small brush/leaf area.

Yearly needs

Pollinator calendar

What pollinators need throughout the year, and what to do about it.

Late winter/early springEarly nectar/pollen; safe places to warm upLeave last year’s stems/leaves in place; plan for early-blooming natives; avoid spring “clean-up” that removes shelter
SpringSteady pollen for bee brood; fresh blooms; nesting sitesPlant early bloomers; keep a small patch of bare, well-drained soil; avoid pesticides and “weed-and-feed” products
SummerContinuous nectar; water; shade/shelter during heatAdd mid-season flowers; provide a shallow water dish with stones; keep blooms coming in sunny clusters
Late summer/fallHigh-energy nectar for late-season insects; seeds/structurePlant late bloomers; avoid deadheading everything; leave some seedheads and stems standing
Winter or Dry SeasonOverwintering shelter; undisturbed nestingLeave stems, leaf litter, and a “messy corner”; delay major cutbacks until the next growing season

Seed mix concept

A Billion Small Steps Seed mix

A simple way to plan a seed mix (or plant set) here is to build it in three layers so pollinators have food across the whole growing season:

Spring starter

Spring starter: early bloomers (often shrubs and early perennials) to help emerging bees.

Summer bridge

Summer bridge: reliable mid-season flowers that carry pollinators through the busiest months.

Fall finisher

Fall finisher: late-season asters/goldenrods (or other late natives) to fuel the last wave of pollinators before winter.
