Green spaces are becoming more fragmented, isolated by concrete and brick, yet they are more vital than ever for both wildlife and people. The need to protect and connect green spaces of all sizes is essential and urgent for climate resilient communities. 

What are green corridors?

Green corridors, also called wildlife corridors or urban green pathways, are stretches of green space that link natural habitats. These connections allow wildlife to move, feed, breed and adapt to climate change such as drought, flooding and extreme weather events.

They can include:

• Nature reserves, parks and woodlands
• Rivers, streams and ponds
• Roadside verges and hedgerows
• Allotments, gardens and green roofs
• Wildflower meadows and containers
• Climbing plants on walls and fences

In Bristol, much of the green space exists in fragmented patches. Community spaces, allotments and individual gardens can support local biodiversity, but when they are linked, they become powerful, connected networks for wildlife. The connected space then functions as a larger habitat area with more resources and support for wildlife. Connectivity is key to survival.

In Lockleaze, the sports centre’s outdoor space, village greens and individual gardens form a green corridor with nature stepping stones for the common blue butterfly and other wildlife between the railway line and Stoke Park. 

‘Nature stepping stones’ are small patches of habitat that allow wildlife to move between larger green spaces, such as reserves, parks and common green spaces. They help wildlife to survive by safely moving, feeding, finding mates and adapting to environmental changes and development.

Tree-mendous

Trees are a core part of these corridors. They provide shelter, food and nesting spots for birds, insects and mammals. For bats like the common pipistrelle, trees act as both shelter and navigation markers.

Different native trees bring unique benefits. Birch attracts invertebrates, rowan trees provides berries for birds and crab apple supports both bees and birds. In urban environments, trees also help cool overheated streets, absorb rainwater, improve air quality and store carbon. Plus street trees enhance wellbeing and community pride, making them an obvious choice for resilient and sustainable city planning. 

Small action, big impact

Nature needs to be connected to survive, which is why all actions for nature make a difference collectively. 

• Planting wildflowers in pots and containers
• Hedgehog highways
• Protecting trees
• Wildlife ponds of all sizes
• Green roofs and vertical gardening
• Greening up front gardens
• Community Nature Reserves

In Bedminster, Tom and his family transformed their urban garden into a wildlife haven. By adding a wildlife pond, dead hedges, bee hotels and two green roofs, they created a rich habitat for bees, birds and hedgehogs. They reimagined their garden from the perspective of the wildlife they hoped to attract.

In urban areas, green roofs are an excellent way to extend wildlife-friendly spaces, whether on large or small surfaces.

Community power

Social connections make a difference, especially in green spaces. Community strength and neighbourhood pride go a long way to encourage green corridors locally and viewing the area as one large ‘Community Nature Reserve’ makes a difference.

You don’t have to be a city planner to help build green corridors, though that would certainly make a huge difference! There are meaningful actions individuals and communities can take to attract and support wildlife, even in small spaces. By prioritising green corridors and connectivity, cities can become more resilient, sustainable and enjoyable places to live.
