Ep 232 - Biodiversity on our Bodies!

In this lively, idea packed episode of The Forest School Podcast, Lewis and Wem move from Halloween chatter to a full nature reset. Wales waterfalls, Pen y Fan, Regent’s Park squirrels, and the deer rut at Richmond Park set the scene for a deeper dive. Lewis picks up Ludo Botany again and invites listeners to help build a new series, starting with tree climbing. The pair then unpack a Finnish trial that “rewilded” kindergartens with real forest floor to boost children’s microbiomes, compare new Australian findings, and explore equity, ethics, hygiene practice, and culture change. A new original song appears too. It is written from the viewpoint of an oak tree watching its acorns become craft supplies. 🌳⏱ Chapter Timings00:00 – Patreon intro and scene setting01:12 – Halloween, Wales waterfalls, Pen y Fan, London parks, and the deer rut07:02 – Ludo Botany returns and a listener call out for tree climbing nominations09:21 – New song premiere about acorns and seasonal crafting13:28 – Finland’s “forest floor in preschool” study and children’s microbiomes20:12 – Australian follow up and wider wellbeing gains beyond health22:55 – Mud as equity and even an academic intervention for learners26:30 – Ethics and longevity of transplanted soil and maintenance questions33:22 – Practicalities in settings: hygiene, thresholds, roles, and risk benefit35:56 – Alternatives: link settings to real woodlands and use green hedges to cut pollution🌲 KeywordsForest School, microbiome play, rewilded kindergartens, Finnish early years, Australian study, loose parts, hygiene thresholds, equity in education, tree climbing, Ludo Botany, Richmond Park deer rut, Welsh waterfalls🔖 Hashtags#ForestSchool #OutdoorEducation #NaturePlay #EarlyYears #ChildDevelopment🎧 Catch the full episode:Spotify: https://shorturl.at/4WdyIYouTube: https://shorturl.at/3qOUsApple: https://shorturl.at/FxfMFRSS: https://shorturl.at/A0kx9📚 Article and studies mentionedGuardian feature: https://www.theguardian.com/environment/2025/oct/29/soil-sandpit-children-dirty-biodiversity-finnish-nurseries-research-microbes-bacteria-aoeFinnish intervention study (Science Advances, 2020): https://www.science.org/doi/10.1126/sciadv.aba2578Open-access version: https://pmc.ncbi.nlm.nih.gov/articles/PMC7556828/Australian childcare soil microbiome study (2024): https://pubmed.ncbi.nlm.nih.gov/38583619/Flinders news summary: https://news.flinders.edu.au/blog/2024/06/18/dose-of-dirt-for-healthy-play/On playground pollution barriers with hedges: https://www.cam.ac.uk/research/news/roadside-hedges-can-reduce-harmful-ultrafine-particle-pollution-around-schools and https://www.nature.com/articles/s41598-022-18509-w🌐 More Episodes & SupportListen to more and access resources at www.theforestschoolpodcast.comSupport the show and join our community at www.patreon.com/theforestschoolpodcastFor questions, feedback, or collaboration: [email protected]
