But a green appearance alone does not prove biodiversity or site safety: results depend on local ecology, contamination checks, design, public access, and ongoing management.
A degraded site can become a valuable nature reserve, but restoration works best when ecological goals are planned alongside resident needs, safety, and inclusive governance.
What makes a biodiversity park different from a normal park?
Urban biodiversity is the variety and abundance of life in a city, while urban nature includes the broader range of nature in city settings, from wild green and blue spaces to gardens, roofs, and street trees, according to the World Bank Group’s 2021 report. A lawn-heavy park and a habitat-rich park may both be green spaces, but they can support very different levels and kinds of biodiversity.
Biodiversity parks aim to conserve habitats and species while allowing appropriate public use. Depending on the site, they may also support ecosystem services such as cooling, water infiltration, and flood protection. These benefits are site-specific, not guaranteed by planting trees or increasing green cover alone.

A 2025 review in Nature Reviews Biodiversity links urban biodiversity with climate adaptation and mitigation, ecosystem services, health, well-being, and everyday engagement with nature. The review also notes pressures such as competition for urban space and human impacts, and recommends biodiversity-sensitive design with socially inclusive governance.
Can a wasteland be turned into a nature reserve?
Yes, a degraded or underused site can be restored, but “wasteland” does not mean the land is an ecological blank or automatically safe for public access. Before a project moves forward, planners need to assess existing habitats, contamination, soil suitability, hydrology, and how people or wildlife might be exposed to hazards.
A study in the Journal of Environmental Management of a reclaimed former mining site found substantial soil contamination and potential health concerns for park users. The example shows why landscaping and a green appearance cannot establish that a brownfield is safe. Assessment and management must match the site’s history and intended uses.
Restoration should also account for habitat types, native species, connectivity, and how ecological conditions change over time. Protecting existing habitat may be as important as creating new habitat, and a site’s value cannot be judged by its area or appearance alone.

How can biodiversity parks benefit city residents?
Well-designed biodiversity parks can combine nature conservation with recreation and locally relevant city services. The benefits depend on habitat quality, the park’s location, the people who can reach it, and how the site is managed.
| Potential benefit | What to consider |
|---|---|
| Habitat and species conservation | Habitat types, native species, abundance, connectivity, and monitoring over time |
| Cooling and climate resilience | Local climate, vegetation, water availability, and surrounding built areas |
| Water infiltration and flood protection | Soils, drainage, hydrology, maintenance, and visitor safety around water |
| Recreation and well-being | Who can reach and use the site, what activities it supports, and whether access works for different ages and abilities |
| Equity and public value | Who participates in decisions and how benefits and costs are distributed |
A study of 12 parks in Bradford, United Kingdom, surveyed 128 park users and assessed biodiversity and facilities. The 2018 study, published in Urban Forestry & Urban Greening, found that biodiversity predicted reported psychological restorative benefit, explaining 43% of variation across those parks. This is an association from one study and location; it does not prove that biodiversity caused the reported benefits or guarantee the same result elsewhere.
What can cities learn from restored urban parks?
Aravali Biodiversity Park, Gurugram
The FAO’s account describes Aravali Biodiversity Park as a restoration effort on degraded Panchayat land at a former quarry, where there had been encroachment and dumped waste. The land was transferred to the Municipal Corporation of Gurugram in 2009. Residents’ body iamgurgaon proposed a biodiversity park, with municipal and Haryana Forest Development Corporation participation.
The project’s restoration vision draws on the habitats of the Aravalli range and native plants. FAO’s account also reports that more than 6,000 saplings were planted in early avenues. This case illustrates how civic initiative and institutional collaboration can contribute to restoration; it does not mean the same approach will suit every former quarry or brownfield.

Bishan-Ang Mo Kio Park, Singapore
The Government Architect NSW case study describes a redevelopment that integrated a naturalized river system, stormwater management, recreation, and public space. Singapore’s National Parks Board and Public Utilities Board collaborated on the project.
Water management and public safety are part of the park’s design. A river monitoring and warning system uses water-level sensors, lights, sirens, and audio announcements to alert visitors when water rises. The case shows why nature-based design needs to account for operating constraints and visitor safety, not only ecological aims.
The Government Architect NSW case-study page reports annual visitation rising from 3 million to 6 million after redevelopment and biodiversity increasing by 30% since construction. The page as reviewed does not set out measurement methods or establish that redevelopment alone caused those changes, so treat these as reported case-study figures rather than general outcomes.
How should cities compare biodiversity parks?
Comparisons should look beyond size and visible greenery. The World Bank Group notes that the benefits people receive from urban nature can depend on where they live relative to green space. Cities should assess ecological results alongside access, safety, services, and governance.
| Comparison area | Questions to ask |
|---|---|
| Ecological outcome | Which habitats and native species are present? How are abundance, connectivity, and change monitored? |
| Resident use and access | Who can reach and use the site? What activities does it support, and are paths and facilities usable by different ages and abilities? |
| City services | Does the site contribute to locally relevant goals such as flood protection, cooling, or water quality? |
| Safety and management | Have contamination, soil, water hazards, maintenance capacity, and monitoring needs been assessed? |
| Equity and governance | Who participates in decisions, and how are benefits and costs distributed? |
What can prevent a biodiversity park from succeeding?
A project can fall short if ecological design is separated from safety, maintenance, land-use decisions, or the needs of nearby residents. Contamination may limit how a former industrial or mining site can be used. Poorly planned public access can put visitors or sensitive habitats at risk, while weak long-term management can undermine restoration.
Urban land is also contested. A site’s value, access, and future use should be addressed through transparent decisions and socially inclusive governance. Cities need to consider both ecological outcomes and who benefits from the park.

Residents can take part in local planning, follow park rules, and support monitoring or restoration activities run by responsible organizations. Learning which species are native to the region can help people understand what local habitat needs. Park access and activities should be guided by site-specific rules, particularly around sensitive habitats and water.
FAQ
What makes a biodiversity park different from a normal park?
A biodiversity park is designed to conserve habitats and the variety and abundance of life, while a conventional green space may prioritize recreation or visual landscaping. A park’s green appearance alone does not show how much biodiversity it supports.

Can a former mining site safely become a park?
It may be possible, but safety cannot be assumed from landscaping. Cities should assess contamination, soil suitability, hydrology, existing habitat, and exposure risks for the site’s intended uses, then manage any identified hazards.
Do biodiversity parks improve residents’ well-being?
One 2018 study of 12 Bradford parks found that biodiversity predicted reported psychological restorative benefit, explaining 43% of variation across those parks. The finding is a study-specific association, not proof of causation or a guarantee for every park.
How can a city tell whether a biodiversity park is working?
Measure ecological outcomes such as habitats, native species, connectivity, and change over time, as well as resident access, safety, relevant city services, and who participates in decisions. Green cover or visitor numbers alone do not provide a complete assessment.
