Not Bourne Yesterday
@notbourneyesterday.bsky.social
Community-powered programme, telling the story of the Chilterns chalk streams.
Made possible by the National Lottery Heritage Fund.
Chilterns National Landscape.
In ‘Is a River Alive’ Robert MacFarlane invites us to consider rivers as living beings with agency - not inate geographic features. Not Bourne Yesterday celebrated the River Wye for World Rivers Day, as more than a waterway, but as a site of stories and culture.

Rivers epitomise our memories, culture, habits and ways of being. They connect us to our landscape. We celebrated our extraordinary chalk stream, the Wye, in urban High Wycombe this World Rivers Day - a river that means so much, to so many, for thousands of years.

The How Many Geese cast get it. Chalk streams are globally rare - and we have them in abundance in England. Nine in the Chilterns. Care to hear more? Find our episode titled 'Charismatic crawlies' wherever you get your podcasts!

“Eventually, all things merge into one, and a river runs through it.” (MacClean, 1976). Today is World Mental Health Day, a day to reflect on the rivers that run through our landscapes and minds, inspiring thought and feeling, improving our our mental wellbeing. What is your first memory of a river?

Have you spotted this delicate flower, rising alongside a chalk stream before? It is water forget-me-not. Did you know that the genus for this plant is myosotis, meaning 'mouse ear,' believed to be a reference to the shape of its leaves?! 🐭

Last weekend, we hosted a day of stream-dipping as part of the Hughenden National Trust Summer of Play on the globally-rare Hughenden chalk stream. We dipped in the lush vegetation, uncovering hundreds of minibeasts!
