Overview

About This Region

The Eastern Great Lakes and Hudson Lowlands ecoregion spans areas influenced by the Great Lakes, moderating the climate but increasing snowfall. Originally mixed coniferous-deciduous forest, large swaths have been cleared for agriculture, including dairy and row crops. This habitat destruction, coupled with the use of chemical pesticides and diseases, poses significant threats to local pollinator populations. Restoration of native flowering plants and responsible land management are critical for supporting “A Billion Small Steps.”

What shapes this region

Climate pattern

  • Conditions are shaped by nearby large water bodies and wetlands.
  • Microclimates (small local weather differences) can make one yard warmer, windier, or wetter than another nearby.
  • Seasonal swings are typical, so planning for early, mid, and late blooms matters.

Why pollinators matter here

  • Pollinators support wild plants and many garden crops.
  • Habitat can be fragmented by development, making “stepping-stone” gardens valuable.
  • Wet-to-dry site variation means there’s room for many different native plant choices.
  • Pesticide exposure and lack of continuous bloom can be major limiting factors in managed landscapes.

Seasonal timing

Planting seasons

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

Seasonal timing

  • Early season: Focus on early-blooming natives and leaving spring “mess” (stems/leaves) a bit longer.
  • Mid-season: Add the biggest variety of flowers; aim for multiple colors and flower shapes.
  • Late season: Prioritize late-blooming natives so pollinators can fuel up before cold weather.
  • Dormant season: Planting can still be possible for some perennials/shrubs depending on local conditions; planning and site prep are always useful.

Quick seasonal checklist

  • Choose 3+ bloom windows (early, mid, late).
  • Add at least one clump of the same plant (pollinators find patches faster than single stems).
  • Keep one area pesticide-free and less-tidy for nesting and shelter.

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 up and nestLeave some leaf litter and stems; plant/plan early bloomers; avoid “spring cleanup” that removes shelter too soon
SpringSteady food as populations ramp up; nesting materials and sitesPlant a mix of spring bloomers; keep a small patch of bare, well-drained soil; provide shallow water (pebbles in a dish)
SummerHigh-volume nectar/pollen; shade and water during hot spellsAdd mid-summer natives; group plants in clumps; water new plantings; keep blooms coming (no big gaps)
Late summer / fall“Fuel-up” blooms; seeds and shelter for overwinteringPlant late bloomers; leave seedheads; reduce mowing; keep stems standing where safe
WinterUndisturbed shelter for overwintering insectsLeave stems/leaves in a corner; avoid cutting everything down; plan next season’s additions

Seed mix concept

A Billion Small Steps Seed mix

A simple way to plan (or buy/build) a seed mix is to think in three layers so flowers don’t “run out” mid-year:

Spring starter

Spring starter: early bloomers that wake up pollinators and support early nesting.

Summer bridge

Summer bridge: reliable mid-season flowers that carry the highest activity period.

Fall finisher

Fall finisher: late-season asters/goldenrods and other fall bloomers that help pollinators fuel up before winter.
