Biodiversity and Green Roofs

Within All things green

 

What do we mean by biodiversity?  The was the question asked by Dr Nigel Dunnett at the recent Scottish Green Roof Conference. 

 

Nigel Dunnett suggested that there are four approaches to biodiversity in a green roof scenario:

   

 

1. The promotion of green infrastructure in a city - enabling the movement and flow of species with connectivity and linkage though "stepping stones"
2. Green roof "service stations" - resource rich hot spots providing food, water and shelter for a variety of species.  These green roofs are flower rich with great vegetation diversity.  The flowers do not need to be native - colour and variety is the key.
3. Green roofs targeted to specific species - having identidied target species the habitat can be created to encourage them, be they inverterbrates, certain birds etc.
4. Habitat creation / restoration ecology - green roofs can create target habitats e.g. meadows, wetlands, coastal, urban/post-industrial etc.

Thus, a 'biodiverse green roof' can mean many things and it is important to understand what it is that you want to achieve.

Why not consider Lindum's Wildflower & Sedum Mat next time you want to create biodiversity on a green roof.  A mixture of wildflowers, herbs, sedums, and flowering perennials, with 21 species in total, supplied ready established in a mat made from recycled British textiles, to create an instant, species-rich green roof vegetation mat.
