Network trends

Look for patterns, not just individual detections.

Explore changes in recorded bird activity while taking account of how long each station was operating. These summaries provide context and should not be treated as a substitute for a formal ecological survey.

Important context

A quiet or offline station does not prove wildlife has declined.

Station health records help show when a node was operating. Where coverage is incomplete, results are labelled accordingly. Changes around habitat work are presented as observations, not proof that the work caused them.

Good coverage

The station recorded enough coverage for a more useful period comparison.

Indicative or limited

Useful background, but not enough for a firm ecological conclusion.
