Overview

About This Region

The Ungava Bay Basin/George Plateau region features cool summers and very cold winters (mean annual temp approx. -4.5°C). This severe climate limits the growing season and floral diversity, significantly impacting pollinator activity and survival. Pollinators in this subarctic area face challenges from permafrost, low species diversity, and limited habitat due to cold temperatures and high winds, necessitating specialized adaptations for local species.

Eco snapshot

What shapes this region

Climate pattern

  • Short growing season; timing varies widely by microclimate (small local weather differences)
  • Cool conditions can slow plant growth and reduce bloom windows
  • Sheltered spots near shrubs, rocks, or water can be noticeably more plant-friendly than exposed sites

Why pollinators matter here

  • Short bloom periods make “bloom timing” especially important—gaps can be hard on insects
  • Native flowering plants in natural habitats can be critical food sources when few plants are in bloom
  • Nesting and shelter sites (undisturbed ground, stems, woody debris) can be limited in heavily disturbed areas
  • Avoiding pesticides helps protect small, local pollinator populations that may recover slowly

Seasonal timing

Planting seasons

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

Seasonal timing

  • Early season: Focus on protecting existing early blooms and minimizing disturbance
  • Main growing window: Planting and establishment typically work best when soils are workable and conditions are mild
  • Late season: Prioritize leaving habitat in place (stems, leaf litter, seed heads) rather than “cleaning up”

Quick seasonal checklist

  • Walk your site and note where flowers naturally appear (and when)
  • Add wind protection and moisture-smart placement (sheltered, not waterlogged)
  • Plant in small test patches first; expand only if plants thrive
  • Leave stems and natural debris for nesting and winter shelter

Yearly needs

Pollinator calendar

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

Late winter/early springEarly food sources; safe shelter as temperatures swingAvoid disturbing leaf litter and stems; protect any early-blooming native plants you find
SpringA steady ramp-up of nectar/pollen; nesting sitesKeep areas pesticide-free; leave some bare/undisturbed ground; plant only hardy, locally appropriate natives
SummerContinuous bloom; water; shade/shelter on hot/windy daysAim for overlapping blooms; provide a shallow water source with landing stones; keep some shrubs/structure
Late summer/fall“Last chance” blooms; energy for overwintering; undisturbed habitatAdd late-blooming natives where feasible; stop deadheading everything; leave seed heads and stems
Winter or Dry SeasonProtected overwintering sitesDon’t over-tidy; leave natural cover (stems, leaf litter, woody debris) until well into the next growing season

Seed mix concept

A Billion Small Steps Seed mix

In this ecoregion, seed mixes should be approached carefully: success depends on locally native species and site conditions, and many off-the-shelf mixes won’t match northern realities.

Spring starter

Spring starter: early-blooming, cold-hardy natives (often low shrubs and woodland/edge flowers)

Summer bridge

Summer bridge: reliable mid-season bloomers that can handle exposure (where appropriate)

Fall finisher

Fall finisher: late-season bloomers (where they naturally occur) to prevent end-of-season food gaps
