By observing plant communities in naturally resilient environments, designers can identify robust species for green roof applications, improving their ecological functions. This sustainability research insight is drawn from a 2012 study published in The Atrium (University of Guelph). Using Comparative ecological analysis and field observation, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize plant species that naturally occur in environments mirroring green roof conditions (e.g., shallow soil, drought, exposure) or have demonstrated success on existing green roofs in the region.

Key Findings
- 01Natural ecosystems with similar conditions to green roofs harbor plant species adapted to harsh, low-resource environments.
- 02Existing green roofs in Southern Ontario host a variety of plant species, some of which may be successful due to their natural resilience.
Application
Design takeaway
Prioritize plant species that naturally occur in environments mirroring green roof conditions (e.g., shallow soil, drought, exposure) or have demonstrated success on existing green roofs in the region.
How to apply
When designing green roofs, research local native plant communities found in rocky, dry, or exposed habitats. Supplement this with site visits to observe established green roofs and note successful plant species.
Project actions
- 01When choosing plants for a green roof design, consider the environmental conditions of the roof (e.g., depth of substrate, sun exposure, wind) and research native plants that thrive in similar natural habitats.
- 02Document existing green roofs in your area and observe which plant species are flourishing, as this provides real-world evidence of suitability.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Integrates ecological research with practical design application.
- +Focuses on local context for plant selection, increasing relevance.
Limitations
The study did not include controlled experiments to definitively prove the superiority of these selected species over others, and local microclimates can significantly influence plant success.
Reliability & validity
The reliability of plant identification from ecosystems is high if proper botanical surveys are conducted. Validity is strengthened by cross-referencing with existing green roof observations, but formal performance testing would further enhance it.
Think critically
To what extent can direct mimicry of natural ecosystems be applied to engineered systems like green roofs, and what are the potential trade-offs compared to selecting species based solely on aesthetic or functional criteria?
Design Principles
"Ecological mimicry: Design solutions by observing and adapting principles from natural systems."
Green roofs are increasingly mandated in urban planning to mitigate environmental impacts like stormwater runoff and urban heat. Effective plant selection is crucial for maximizing these benefits, and drawing inspiration from natural ecosystems offers a scientifically grounded approach to identifying suitable species.
What This Means for Your Design
To make green roofs work better, look at plants that grow well in tough, dry spots in nature, like rocky fields or cliffs. Also, see what plants are already growing well on existing green roofs.
How to use in your project

Paragraph starter
Drawing inspiration from natural ecosystems, this design project investigated plant selection for extensive green roofs by analyzing species found in local alvars and rock barrens, environments that share similar substrate and exposure conditions. Furthermore, observations of existing green roofs in Southern Ontario provided empirical data on species that have already demonstrated resilience in this context. This dual approach aims to ensure the selection of robust and sustainable plant assemblages for improved green roof performance.
