This week Adam Walton visits Treborth, Bangor University's botanic garden on the shores of the Menai Straits. This year Treborth is celebrating its golden jubilee and throughout those fifty years it has played a key role for the University and for many other organisations as a living laboratory and as a classroom for the botanists and ecologists of the future.

Adam meets Treborth's curator Nigel Brown and Ph.D student Sophie Williams to discuss the importance of botanic gardens around the world. He encounters a rare fern and hears from CCW upland ecologist Barbara Jones how it was almost wiped out by the Victorian craze for collecting ferns. He explores Treborth's importance as a habitat for many other species besides plants when he goes moth trapping with Iliya Vukomanovich from Butterfly Conservation. And student Mark Long introduces him to the carnivorous plants which feast on insects - and possibly larger animals too!
