On the evidence for evidence‐based conservation

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
We explore the evidence base underlying evidence‐based conservation (EBC). Drawing on varied examples, we suggest that EBC is often (but not always) a justified investment to improve conservation outcomes. We offer suggestions for how to generate further evidence on EBC, framed around a theory of change for how EBC improves conservation outcomes ...
