September is Biodiversity Month and because of this, we’re honouring the wide variety of life that sustains healthy ecosystems from the tiniest soil microbes to the tallest trees and everything in between. In this blog post, we are looking at how we can view infrastructure as an asset to biodiversity rather than the concrete, drains, and retaining walls that often dominate the landscape.
For Orterra Landscape Architects, biodiversity isn’t an afterthought it’s a guiding principle that shapes how we design, restore, and integrate infrastructure into the living world.
Biodiversity Is More Than Green Space
In infrastructure projects, biodiversity isn’t only about planting trees or adding shrubs. It’s about enhancing ecological function at every scale. This looks like:
- Supporting pollinators with native flowering plants
- Restoring soil health so that new vegetative communities can thrive
- Connecting fragmented habitats so wildlife can move freely
- Clean water systems that support aquatic life
- Reducing the impact of weeds
In essence, biodiversity becomes measurable outcomes, not just ornamentation.
Infrastructure as Habitat
Traditional infrastructure can unintentionally fragment habitats and erode local ecosystems. At Orterra, we ask: How can infrastructure itself become part of the natural system?
- Green bridges and wildlife crossings that allow safe animal movement
- Bioengineered drainage systems with plants that filter runoff and prevent erosion
- Revegetated embankments that support native grasses, shrubs, and insects
These design elements don’t just reduce impact, they add biodiversity value.
Design With Local Ecologies, Not Against Them
One of the most important principles we apply is context-led design. What species are native? What plants are resilient in local conditions? What ecosystems existed historically?
This understanding informs:
- Plant palettes based on local provenance
- Soil improvement strategies that support thriving root systems
- Infrastructure alignment that avoids sensitive wetlands
By working with local ecologies, infrastructure can be an ally not a threat.
Articulating Biodiversity in Project Outcomes
Biodiversity shouldn’t sit in design guides or technical reports it should be evident in project outcomes. This might look like:
✔ A freshwater corridor supporting native fish and invertebrates
✔ Roadside verges buzzing with native pollinators
✔ Rehabilitated soil teeming with microbial life
✔ Habitat mosaics that sustain birds, bats, frogs, and more
These outcomes aren’t incidental they’re designed, measured, and celebrated.
Beyond Construction: Long-Term Stewardship
Biodiversity isn’t “done” when construction wraps up. Real success lies in long-term ecological health:
- Maintenance schedules aligned with wildlife needs
- Adaptive management as ecosystems mature
- Monitoring ecological indicators (e.g., species diversity, water quality)
We work with project teams, clients, and communities to ensure biodiversity thrives long after the plans are signed.
Why It Matters
Infrastructure shapes our everyday world how we travel, how water flows, how cities grow. When biodiversity is integrated into these systems, we don’t just protect nature we enhance human well-being:
- – Cleaner air and water
– Resilient landscapes in the face of climate change
– Greener, healthier communities
Biodiversity becomes a shared legacy.
This Biodiversity Month, let’s reimagine what biodiversity looks like in infrastructure projects. It may not always be a dense forest or a pristine wetland it might be the subtle hum of native bees along a rehabilitated verge, or the return of frogs to a once-degraded drainage pond.
At Orterra Landscape Architects, we believe biodiversity is an achievable part of modern infrastructure design. Together, we can make infrastructure that supports life, not just movement. If you are planning a project and want to unlock biodiversity outcomes, let’s talk about how we can help shape it from day one.
