Ghent Botanical Garden Faces Species Decline Due to Increasing Heatwaves
The Botanical Garden in Ghent, Belgium, is at risk of losing plant species if heatwaves and dry periods continue to escalate. This warning comes from the Ghent University Museum (GUM). Prolonged warm and dry spells can lead to the depletion of rainwater reserves, forcing the garden to rely on groundwater. This groundwater is often high in calcium carbonate, which can be detrimental and even fatal to certain plant species. Consequently, the diversity and number of plants housed within the garden may significantly decrease in the future.
The increasing frequency of heatwaves and droughts presents a systemic challenge for botanical gardens worldwide. These institutions, tasked with preserving biodiversity, are now confronting environmental shifts that directly impact their collections. The reliance on groundwater, while a necessary adaptation, introduces new chemical stressors like high calcium content, highlighting a complex trade-off between water availability and plant health. This situation underscores the need for advanced water management strategies and potentially the development of more resilient plant varieties, anticipating a future where climate change necessitates a re-evaluation of traditional horticultural practices and conservation methods.
