Payments for Ecosystem Services (PES) is a term used to describe a range of schemes through which the beneficiaries, or users, of ecosystem services provide payment to the stewards, or providers of those services.  A number of Ecosystems Knowledge Network members are involved in piloting PES schemes, or assessing their potential. As reported in the Spring edition of Ecosystems News, a team commissioned by Defra has been developing a Best Practice Guide for PES and a set of supporting PES case studies. Comments are invited on a  draft version of the guide and case studies.  The deadline for responses is 21st September 2012. The final version will be published by Defra later in the year.
