Watson Highlands

Watson Highlands is a region extending from west of Dawson in the Yukon southeast into northeastern British Columbia, characterized by rolling uplands, small mountain groups, and nearly level tablelands, with extensive open forests of white spruce and other species, moderate to low density river systems, and land uses including mining, recreation, hunting, and trapping.

Overview

About This Region

The Ellesmere and Devon Islands Ice Caps ecoregion, characterized by a high arctic ecoclimate with very short, cold summers, presents a challenging environment for pollinators. Most of the area is barren ice and snow, limiting suitable habitat and forage. Dominant vegetation includes clumps of cold-hardy plants like moss, lichen, sedge, and cottongrass. The low species diversity and cold temperatures (-2°C mean summer) are primary factors affecting pollinator populations. With no settlements, human development impact is minimal, but the extreme climate is the critical limiting factor.

What shapes this region

Climate pattern

  • Winters are typically long; spring can arrive unevenly across the landscape.
  • Summer warmth is often brief, and cool nights are common in many places.
  • Wind exposure and slope direction (south-facing vs. north-facing) can strongly affect what grows.
  • Microclimate (small local weather differences) can make one site plantable while another nearby is not.

Why pollinators matter here

  • Short bloom seasons mean pollinators rely on concentrated bursts of flowers.
  • Native flowering shrubs and hardy perennials can be key food sources when they bloom.
  • Nesting habitat (bare ground, stems, woody debris) can be as important as flowers.
  • Small, sheltered plantings can act like “stepping stones” between natural patches.

Seasonal timing

Planting seasons

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

Seasonal timing

  • After snowmelt: Site cleanup, light soil prep, and planning for early blooms.
  • Late spring to early summer: Main planting window in many places (site-dependent).
  • Mid-summer: Watering and “bloom gap” checks—add a few mid-season bloomers if needed.
  • Late summer to early fall: Planting hardy perennials/shrubs can work in some microclimates; also a good time to plan next year’s early blooms.

Quick seasonal checklist

  • Choose plants that can handle short seasons and local conditions.
  • Aim for 3 bloom periods (early / mid / late).
  • Leave some areas undisturbed for nesting and overwintering.
  • Keep it pesticide-free.

Yearly needs

Pollinator calendar

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

Late winter / early springEarly nectar and pollen when few flowers are availablePrioritize early-blooming native shrubs/perennials; avoid spring pesticide use; leave some leaf litter/plant stems until weather is consistently mild
SpringSteady food and safe nesting startsPlant or protect spring bloomers; add bare, well-drained soil patches for ground nesters; provide a shallow water source with landing stones
SummerContinuous blooms and heat/drought support (site-dependent)Fill bloom gaps with mid-season natives; water new plantings as needed; keep some areas “messy” (stems/wood) for nesting
Late summer / fallHigh-energy nectar for late-season insects and next-year queensAdd late bloomers; avoid cutting everything back; let some seedheads and stems stand
WinterShelter and undisturbed nesting/overwintering sitesLeave stems, leaf litter, and some dead wood; avoid heavy fall cleanup; plan next year’s bloom sequence

Seed mix concept

A Billion Small Steps Seed mix

In short-season regions like Watson Highlands, a simple seed mix plan can help you avoid bloom gaps:

Spring starter

Spring starter: early-blooming species (and/or shrubs) that provide the first food after winter.

Summer bridge

Summer bridge: reliable mid-season bloomers that carry pollinators through peak activity.

Fall finisher

Fall finisher: late bloomers that help late-season insects and next-year queens fuel up.
