The 2024/25 Wednesday Webinar series (kindly sponsored by Stihl) was another great success, with the 14 webinars attracting an audience of more than 6,000 people from 60+ countries.
As ever, we covered a diverse range of subjects including British bats, orchards, heritage trees of Scotland, fluid dynamics, phytoremediation, tree species selection, practical tree management wisdom and much more. Almost all the webinars in the series – and many more - are available to watch via the Association’s website. Scan the QR code to access the webinar archive.
Over the years our wonderful speakers have contributed to an eclectic list of their favourite tree books, which we reproduce here for your reading pleasure – even after 96 webinars we still rarely have repeat selections, and our presenters never fail to surprise and inspire us.
The Wednesday Webinars will be back in autumn 2025 for another exciting series which will bring you the best speakers and most interesting projects from around the world, piped into your home or office and absolutely free of charge. Obtaining CPD or CEU credits has never been more accessible.
If you have a suggestion for topics or presenters then please do let me know at john@trees.org.uk and we will give it some thought.
The 2025/26 series will also bring our 100th webinar, so for that one you can almost certainly look forward to a no-expense-spared extravaganza.*
*Terms and conditions apply, no-expense-spared extravaganza available only while stocks last.
