Abstract

Robust impact evaluations are needed for conservation to learn and grow as a field. Currently we lack a large body of evidence on the effects of behaviour change interventions in social‐ecological systems. By uncovering mechanistic relationships and establishing causality we can refine future programmes to enhance likelihood of effectiveness. Although a range of sophisticated methodological approaches to evaluation have been developed, conceptually linking project outcomes with conservation impacts remains difficult in complex systems.

However, multiple unforeseen difficulties arose which complicated attempts at causal attribution. We were hampered by spatial spillovers, design effects from the sensitive questioning technique, concurring law enforcement and changes in biological monitoring effort. These challenges highlight the difficulties faced by practitioners seeking to apply impact evaluations in the field. We reflect on what this means for future impact evaluations of behaviour change interventions in conservation. Our recommendations include combining multiple outcome measures to triangulate hard‐to‐measure behaviours and theory‐based evaluation methods to explore causal impacts.
