The BIG Biodiversity Challenge to 'do one thing' invites you to add one new biodiversity enhancement to your construction site, development or existing building.


The BIG Biodiversity Challenge is a CIRIA Biodiversity Interest Group (BIG) initiative, launched on 14 October 2013.  Since its launch in 2013 the challenge has grown considerably and attracts organisations from across a wide range of stakeholder groups.


The Challenge aims to:


  • Raise awareness of the importance of protecting and enhancing biodiversity in the built environment to all those who work in the construction industry

  • Encourage construction teams to collaborate with local communities to ensure long term awareness and protection of local biodiversity

  • Promote the integration of biodiversity in green infrastructure initiatives

  • Support the targets of Biodiversity 2020 strategy in the built environment.



"With a little planning and cost, simple and effective action can be taken for biodiversity in the built environment - what could you do?"

Martin Ballard, Group Environmental Manager, Willmott Dixon Group

What is a biodiversity enhancement?


A biodiversity enhancement is an action that improves biodiversity and ecological habitat in the local environment. Enhancements should increase opportunities for local biodiversity and go beyond normal business practice or predetermined planning or construction conditions.


The biodiversity enhancement can be large or small scale and can be permanent or temporary measures. It could also include initiatives such as creating biodiversity champions in your organisation, or programmes that engage with the local community. Find out more about the award categories.


The Challenge demonstrates that small enhancements are the crucial first step in engaging with and understanding biodiversity.
