Overview

About This Region

The Coppermine River and Tazin Lake Uplands ecoregion, spanning from Nunavut to the Northwest Territories, is defined by its rugged landscape and rich wildlife, including caribou and muskox. The sparse vegetation supports local pollinator populations, which face challenges from climate change, habitat loss, and potential chemical exposure. Protecting this unique arctic environment is vital for maintaining the delicate balance that sustains its biodiversity, especially its essential pollinator species.

What shapes this region

Climate pattern

  • Short growing season; timing varies widely by exposure and shelter.
  • Cool nights are common even in summer.
  • Microclimate = small local weather differences (sunny rock outcrops vs. shaded forest vs. windy shorelines).

Why pollinators matter here

  • The flowering season is brief, so timing (early-to-late bloom coverage) matters a lot.
  • Many pollinators rely on small, scattered flower patches rather than large gardens.
  • Nesting sites can be limited by wet soils, shallow soils, or frequent disturbance.
  • Avoiding pesticides is especially important where recovery time is slow and habitats are naturally sparse.

Seasonal timing

Planting seasons

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

Seasonal timing

  • After snowmelt / early warm season: focus on site prep, small hardy plantings, and protecting existing blooms.
  • Mid warm season: maintain moisture for new plants, and add “bridge” blooms if you have gaps.
  • Late warm season: prioritize late-blooming flowers and avoid heavy cleanup that removes shelter.

Quick seasonal checklist

  • Choose the sunniest, most sheltered spot you have (a wall, fence, or rock edge can help).
  • Start small: one pot, one bed edge, or one protected corner.
  • Aim for early + mid + late blooms (even if the list is short).
  • Leave some natural areas “messy” for nesting and overwintering.

Yearly needs

Pollinator calendar

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

Late winter / early springSafe shelter as temperatures swing; early food when availableDelay major cleanup; keep leaf litter/plant stems in a corner; plan a small planting for the earliest bloom window your site can support
SpringEarly nectar and pollen; water; nesting sitesProtect existing early flowers; add hardy early-bloom natives where feasible; keep a shallow water dish with stones (in a safe spot)
SummerSteady bloom; shade breaks; pesticide-free habitatAdd mid-season flowers (pots work); water new plants during dry spells; avoid all insecticides and “systemic” treatments
Late summer / fallLate nectar; places to overwinterPlant or protect late bloomers; leave stems/seedheads; keep some bare/undisturbed ground if you have it
WinterUndisturbed shelterDon’t “reset” the whole garden; leave natural debris in place; plan next season’s bloom sequence

Seed mix concept

A Billion Small Steps Seed mix

In this region, seed mixes can be tricky because establishment is highly site-dependent and locally native species matter. If you use seed, think in three simple roles (and choose locally appropriate native species for each role):

Spring starter

Spring starter: early blooms to help the first active pollinators

Summer bridge

Summer bridge: steady mid-season flowers to prevent a “hungry gap”

Fall finisher

Fall finisher: late blooms that fuel pollinators before winter

Native plants

Plants that thrive in this region

Alders (*Alnus* spp.)

Alders

Alders are fast-growing trees in the genus Alnus that are especially useful in damp spots and along edges where you want quick cover and early-season pollen for insects.

Birches (*Betula* (genus))

Birches

Birches are graceful trees in the genus Betula, known for their often light-colored bark and early-season pollen and catkins that support springtime insects.

Poplars, aspens & cottonwoods

Poplars, aspens, and cottonwoods (genus Populus) are fast-growing trees best known for their fluttering leaves and soft “cottony” seeds. They can support early-season pollinators with spring catkins, but they’re also big, thirsty, and often short-lived in small yards—so they’re best chosen with space and roots in mind.
