Detecting rare and endangered species is critical for guiding conservation action and ensuring that limited resources are directed where they can have the greatest impact. Accurate information on species presence, distribution and population trends allows priority habitats to be identified, threats to be assessed and the effectiveness of management interventions to be evaluated. 

Because rare species are often difficult to observe using traditional survey methods, sensitive monitoring approaches can provide early evidence of populations declines or persistence, allowing timely actions to support species protection before losses become irreversible.
