Overview

About This Region

The Lower Mainland & Puget Lowland is a vital, diverse region for pollinators, including bees, butterflies, and bats. This area’s mix of urban development and agricultural land creates unique challenges for these species. Habitat loss due to urbanization, pesticide use in farming, and the introduction of non-native species are significant factors affecting pollinator health and populations. Conservation efforts focus on creating green corridors and promoting native plant species to sustain these essential animals for our ecosystem and food security.

What shapes this region

Climate pattern

  • Ocean influence often moderates temperatures compared with inland areas.
  • Rain and cloud cover can be common outside of summer; summer dryness can be significant in many neighborhoods.
  • Microclimates (small local weather differences) matter a lot—coastal vs. inland, sunny vs. shaded, and sheltered vs. windy sites can behave like different gardens.

Why pollinators matter here

  • Pollinators support native plant reproduction and healthy food webs in parks and natural areas.
  • Urbanization can reduce nesting sites and “continuous bloom,” making gardens and schoolyards especially valuable.
  • Early-season flowers can be critical when emerging pollinators have few options.
  • Summer dry periods can create nectar/pollen gaps unless gardens are planned for drought-tolerant bloom.

Seasonal timing

Planting seasons

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

Seasonal timing

  • Late winter to early spring: Plan, observe sun/shade, and start with early bloomers in pots or beds when conditions allow.
  • Spring: A common time for planting and adding a wider variety of natives; aim to establish plants before summer dryness.
  • Summer: Focus on watering new plantings, mulching thoughtfully, and adding heat/drought-tolerant bloomers.
  • Late summer to fall: Often a strong season for planting perennials and shrubs so roots can establish before winter.
  • Winter: Do gentle maintenance; leave stems/leaf litter in place for shelter where possible.

Quick seasonal checklist

  • Choose at least 3 bloom windows (early, mid, late).
  • Add one shrub (long-term nectar/pollen) if you have space.
  • Keep one small “messy” corner for nesting and shelter.
  • Water new plants through their first dry season (site-dependent).

Yearly needs

Pollinator calendar

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

Late winter / early springFirst nectar and pollen; safe places to warm up and nestPlant/maintain early bloomers; leave some leaf litter and stems; avoid “spring cleanup” that removes shelter
SpringSteady bloom and nesting materialsAdd a mix of flowers + at least one native shrub; keep some bare soil patches; provide shallow water (pebbles for landing)
SummerDrought-resilient flowers; shade and water nearbyPrioritize summer bloomers; water new plantings; avoid pesticides; let some herbs/flowers go to bloom
Late summer / fall“Last chance” nectar/pollen to fuel overwinteringPlant late bloomers; avoid deadheading everything; leave seedheads and stems for wildlife and future nest sites
WinterShelter from cold/wet; undisturbed nesting sitesLeave stems standing; keep logs/woody debris in place where safe; plan next year’s bloom sequence

Seed mix concept

A Billion Small Steps Seed mix

A simple way to plan a pollinator patch is to think in three layers that cover the whole growing season:

Spring starter

Spring starter: early bloomers (often shrubs and bulbs) that feed emerging pollinators.

Summer bridge

Summer bridge: drought-tolerant mid-season flowers that keep nectar/pollen available through dry spells.

Fall finisher

Fall finisher: late bloomers (like asters and goldenrods) that prevent an end-of-season food gap.
