Welsh filmmaker Ross Pierson has announced his latest documentary, “The Red List,” which sheds light on the vital work being done at the National Botanic Garden of Wales to protect the country’s most endangered plant species. The film, self-funded and filmed over the course of a year, pairs stunning visuals with the renowned naturalist Iolo Williams as he takes viewers on a journey through the Garden’s laboratories, horticultural center, and remote locations in the Welsh countryside.
Director Ross Pierson explains, “Plant conservation may not often make headlines, but it is crucial for the survival of our ecosystems. When I learned about the dedicated work being done at the Garden, I knew it deserved to be showcased. This film aims to bring awareness to the fight to save our botanical heritage and overcome ‘plant blindness.'”
The documentary showcases the efforts of botanist Dr. Kevin McGinn and his colleagues as they work to locate and propagate endangered species in Wales, search for rare plants in unexpected habitats, and partner with London’s Kew Gardens to preserve biodiversity for future generations. The film also highlights the personal stories of the scientists and horticulturists who are passionate about leading Wales to the forefront of conservation efforts.
“The Red List” will premiere at the Raindance Film Festival on June 27th, 2025, followed by an exclusive screening at the National Botanic Garden of Wales’s Theatre Botanica on July 25th, 2025. The July event will also serve as the finale of a joint crowdfunding campaign between Pierson and the Garden to support the film’s final production costs and wider distribution.
