Where climate refugia occur is not always where protection is most feasible
WHAT THE EVIDENCE SAYS
Researchers mapped potential climate refugia using topographic diversity and projected climatic and plant-distribution changes, then overlaid those priorities with plant biodiversity, accessibility, proximity to protected areas and a parcel-size cost proxy. Refugia potential was strongest in the Andes, but incorporating conservation feasibility shifted mapped opportunities toward coastal ecosystems. The result identifies places where ecological priorities and implementation conditions overlap; it is not a controlled comparison of small and large reserves.
WHY IT MATTERS / OUR READ
A map of ecological value and a map of feasible conservation action answer different questions. Keeping both visible helps planning teams distinguish what deserves protection from what can realistically be secured and managed. A feasibility score should prompt landowner, cost and field checks—not substitute for them.
CAVEATS / UNCERTAINTY
These are modeled priorities, not verified future safe havens. The top-30% refugia cutoff is a planning threshold; plant models and future-climate assumptions constrain resolution and scope. Parcel size is not a measured land price. We do not use the paper's unreconciled area totals or counts of ecosystems meeting protection targets, and infer no acquisition-cost saving.
