Unveiling the Historical Impact of Climate Change through Centuries-old Herbaria and Pressed Flowers

A study conducted by botanists in Italy has demonstrated that changes in plant life due to climate change can be traced by analyzing herbaria collections made by plant enthusiasts over centuries. By comparing plant samples from different time periods in the same area, the researchers observed changes in plant populations, diversity, and the disappearance of certain species. They also noted an increase in non-native species, potentially due to trading, and identified the impact of climate events on plant distribution. The study highlights the long-term effects of climate change on plant ecosystems.
