This project evaluation tool (Kapos et al., 2008) draws on a conceptual framework (Kapos et al., 2008) that builds on the concept of results chains for conservation interventions (Salafsky et al., 2001, 2008). Together, the framework and evaluation tool can be used to investigate the link between intermediate steps (such as activities, outputs and outcomes) and the ultimate success (conservation effects) of a project. By using a preliminary dataset CCF members have demonstrated that measuring outcomes can be a better alternative in terms of how easily the measures can be derived and how well they predict longer-term effects on conservation targets, rather than focusing on the more common measures of project implementation which are typically reported to donors to assess conservation effects.
