A documentary produced by ARTE explores how botanical gardens across Europe serve as critical sanctuaries for plant biodiversity during the climate crisis [1].
These institutions act as living archives, preserving species that are increasingly threatened by rapid environmental changes and habitat loss. By maintaining genetic diversity outside of unstable wild environments, these gardens provide a final line of defense against total extinction for various flora [1, 2].
Directed by Angela Scheele, the film has a runtime of 44 minutes [1]. It documents the specific efforts of botanical gardens in diverse locations, including Berlin, London, and the French Alps [1]. The production emphasizes the transition of these spaces from historical curiosities to essential scientific hubs for conservation [2].
Botanical gardens maintain curated collections that allow researchers to study plant resilience and adaptation. This work is vital as the climate crisis accelerates, pushing many species toward the brink of disappearance [1, 2]. The documentary illustrates how these curated spaces bridge the gap between historical botanical study and modern ecological survival.
Released in 2024, the film remains available for streaming until Aug. 20, 2026 [1]. It serves as a visual record of the ongoing struggle to catalog and protect the natural world before it is lost to environmental degradation.
“Botanical gardens across Europe act as sanctuaries for plant biodiversity in the climate-crisis era.”
The shift in the role of botanical gardens from aesthetic displays to genetic reservoirs reflects a broader global strategy in conservation biology. As wild habitats become less viable due to temperature shifts and extreme weather, ex situ conservation—preserving species outside their natural habitat—becomes a primary tool for preventing permanent biodiversity loss.
