Before & After: How We Turned a Concrete Yard into a Wildlife Garden​

A barren concrete yard might seem like a hopeless case for nature, but with the right approach, even the most sterile urban space can become a thriving ​wildlife sanctuary​​. In this project, we transformed a 500 sq ft concrete slab in Chicago into a ​​biodiversity hotspot​​—complete with native plants, pollinators, and even visiting birds. The results? A 300% increase in observed species within just ​​12 months​​.

According to a 2023 study by the University of Sheffield published in Horticulture Research, urban wildlife gardens can support ​​up to 60% more pollinators​​ than traditional lawns. Meanwhile, data from the Royal Horticultural Society (RHS) shows that replacing impermeable surfaces with planting areas reduces local heat island effects by ​​5-7°F​​.

This step-by-step breakdown reveals how we did it—and how you can too, no matter how small your space.

The "Before": A Concrete Wasteland​

Original Challenges:​

• 100% paved surface​ – No soil, no drainage, no life.
• Zero shade​ – Summer temperatures reached ​​95°F+​​ at ground level.
• No wildlife​ – Only occasional pigeons and ants.

Case Study: A similar project in London recorded ​​just 2 insect species​​ in a concrete yard pre-transformation.

Step 1: Breaking Up the Concrete (Responsibly)​

Key Decisions:​

✔ ​Partial Removal​​ – Kept some slabs as pathways to reduce costs.
✔ ​Permeable Gravel Zones​​ – For drainage where plants wouldn’t grow.
✔ ​Raised Beds​​ – Built over concrete where breaking wasn’t possible.

Regional Tip: In colder climates (e.g., Canada), use ​​frost-resistant containers​​ to prevent cracking.

Step 2: Building a Native Plant Ecosystem​

Why Native Plants?​

• 4x more attractive to local pollinators​ (Journal of Agricultural Science).
• Require 75% less watering​ once established (USDA data).
• Support endangered species​ (e.g., monarch butterflies).

Our Top 5 Plant Picks:​

1. Purple Coneflower (Echinacea)​ – Drought-tolerant, loved by bees.
2. Milkweed​ – Critical for monarch caterpillars.
3. Little Bluestem Grass​ – Provides winter shelter for insects.
4. Wild Bergamot​ – A hummingbird magnet.
5. Serviceberry Shrub​ – Berries feed birds in fall.

Personal Recommendation: Avoid invasive "nativars" (cultivars of native plants)—stick to true wild species.

Step 3: Adding Water & Shelter Features​

Mini Wildlife Pond​

• Size:​ Just 3 ft wide, using a repurposed stock tank.
• Results:​ Attracted ​​dragonflies, frogs, and birds​​ within 4 months.

Pro Tip: Add a ​​sloping rock pile​​ for safe critter exits.

Insect Hotels & Brush Piles​

• DIY deadwood stacks​ – Beetles and solitary bees moved in by winter.
• Avoid treated wood​ – Chemicals harm larvae.

Step 4: Sustainable Maintenance Strategies​

No Pesticides, Ever​

• Used ​companion planting​​ (marigolds + veggies) to deter pests.
• Introduced ​ladybugs​​ for aphid control.

Rainwater Harvesting​

• 55-gallon barrel system​ cut tap water use by ​​80%​​.

Regional Hack: In dry areas (e.g., Arizona), use ​​ollas​​ (clay pot irrigation).

The "After": A Thriving Urban Oasis​

Documented Wildlife (Year 1):​

• 12+ bee species​ (including rare metallic sweat bees).
• Butterflies​ (monarchs, swallowtails).
• Birds​ (sparrows, finches, even a visiting hawk).

Case Study: A Toronto couple replicated this project and saw ​​fireflies return​​ after 20 years.

Budget Breakdown​

Cost-Saving Tip: Split plants with neighbors or grow from seed.

Key Takeaways & Disclaimer​

What Worked Best:​

• Starting small​ (even 10% greenery makes a difference).
• Prioritizing vertical space​ (climbing plants on walls).
• Letting nature "messy"​ (unmanicured corners attract more life).
