{"slug":"nationale-boomfeestdag","name":"Stichting Nationale Boomfeestdag","tagline":"The Dutch national tree-planting day for schoolchildren, held every year since 1957","description":"Stichting Nationale Boomfeestdag in Tilburg organises the Netherlands' national tree-planting day for primary-school children, first held on 10 April 1957 in Apeldoorn after the FAO raised the alarm on deforestation; the foundation says 5 million children have planted 10 million trees since then. Since 2020 the national Boomfeestdag opens a planting season on the third Wednesday of November that runs to the third Wednesday of March, during which municipalities, schools, scouting groups and nature clubs register their own local planting celebrations on the foundation's map, order trees via partner nursery Ebben and use its tree-education platform. The 69th edition opens on 18 November 2026 at Landgoed Prattenburg (Rhenen/Veenendaal) with about 300 children, while more than 20,000 children are expected to plant trees in municipalities nationwide that day. It also runs Kinderbossen (children's forests) in eight provinces and provincial celebrations.","website_url":"https://www.boomfeestdag.nl","logo_url":"https://www.boomfeestdag.nl/uploads/Logos-Boomfeestdag/LOGO-BFD-2020-200-px-RGB.jpg","founded_year":1957,"org_type":"nonprofit","scope":"national","headquarters":{"city":"Tilburg","region":"North Brabant","country":"NL","lat":51.5555,"lng":5.0913},"volunteer_url":"https://www.boomfeestdag.nl/organisatoren","donation_url":"https://www.boomfeestdag.nl/doneer","events_url":"https://www.boomfeestdag.nl/activiteiten","featured":false,"trees_on_record":10000000,"primary_activity":"education-advocacy","activities":[{"slug":"education-advocacy","name":"Education & advocacy","primary":true},{"slug":"reforestation","name":"Reforestation","primary":false},{"slug":"urban-forestry","name":"Urban forestry","primary":false}],"updated_at":"2026-11-08T00:02:16.194Z","url":"https://treerm.org/org/nationale-boomfeestdag","markdown_url":"https://treerm.org/org/nationale-boomfeestdag.md","api_url":"https://treerm.org/api/v1/organizations/nationale-boomfeestdag","data_note":"The foundation publishes only cumulative totals (10 million trees, 5 million children since 1957) and no per-season tree or child counts; its ANBI form is an image PDF that could not be text-extracted.
