Contact area assignments contain Tailte Éireann Local Authorities – National Statutory Boundaries – Ungeneralised 2026, © Tailte Éireann, licensed CC BY 4.0 (https://creativecommons.org/licenses/by/4.0/). Source: https://www.arcgis.com/home/item.html?id=74b839e09e1c48f2b2fe4efccb52a73d.
Contact facts retain their published council, operator or community-directory sources in contacts.json and contact-research.json. No licence to underlying page text is implied. Community Gardens Ireland entries are member-supplied; their current responsiveness is unverified.

Rich profile additions (checked 31 October 2026): OpenStreetMap fact observations retain ODbL attribution and exact source references. Short council/operator summaries identify their sources and check dates in profiles.json/profile-research.json; source-specific rights remain. Application guide wording is original explanatory content and links to the relevant published guidance. The nine individual site photographs retain their stated CC BY, CC BY-SA or CC0 licences, photographer credits and dates. See photos/CREDITS.txt and profile photo metadata. Photo licences do not change the combined database licence.

Map outline layer: site-areas.json contains OS Open Greenspace geometries (April 2026), matched by exact source reference. Contains OS data © Crown Copyright and database rights 2026; Open Government Licence v3. Source endpoint, check date and original-file digest are retained in its metadata. These mapped growing areas are not legal boundaries or individual plots.
