# ECO-001 — Sparrow abundance and measured base station fields

Why this matters
This retrieval lead concerns whether house-sparrow abundance varies with measured base-station fields. It brings free-living wildlife into the assessment, where habitat and other local conditions can also shape results. The original design and analyses need checking before an observed association can support a causal ecological claim.

Topic: Environmental effects

Verification Group: Retrieval lead

Record Role: Retrieval lead

Featured: False

Exposure: See original source for calibrated field and modulation conditions.

Design: Observational or experimental ecology; original methods pending.

Finding: Discovery dossier reports negative association between house-sparrow abundance and measured GSM fields.

Boundary: A retrieval entry, not a verified ecological causal conclusion.

Protection Question: Does the sparrow-abundance association persist after accounting for habitat and other local conditions? Until original methods and analyses are checked, this is a field-observation lead rather than an ecological causal finding.
