• DEFRA: Payments for Ecosystem services Best Practice Guide
  An expert consortium with hands-on experience of developing Payments for Ecosystem Services (PES) schemes was commissioned to develop a Best Practice Guide in collaboration with potential users. This Guide collates a number of instructive domestic and international case studies demonstrating the various challenges and solutions associated with a PES approach. This Guide will help users to: •understand the principles of PES •identify and test potential opportunities and suitable partners for PES •find solutions to technical, legal and institutional issues.
• Developing the potential for Payments for Ecosystem Services: an Action Plan
  This Action Plan promotes practical and innovative development of Payments for Ecosystem Services (PES) schemes, and considers the actions we can take to enable them. PES schemes are about identifying practical ways to deliver new and additional investment in the natural environment, as well as seeking better targeting and value for money of existing funding streams. The Action Plan considers capacity building actions for government, the key policy areas of opportunity for PES and the monitoring and evaluation needs of PES schemes.

• The Value of Green Infrastructure in Birmingham and the Black Country
  The pressure on the natural environment, especially in urban areas, is increasing. One main reason is that ecosystem services and the benefits they provide to human welfare are ignored or strongly undervalued and not adequately assessed in planning and policy. Most benefits provided by Green Infrastructure are still fairly uncertain and not marketable. The term “Green Infrastructure” describes the structure, position, connectivity and type of green spaces. Environmental economist Oliver Hölzinger has undertaken work on behalf of the Wildlife Trust in an attempt to start to put a value on these services.
