Introduction to Bee Decline
Scientists from Kew Gardens are conducting a new study to determine which trees can help contain the decline in bee populations. The global bee population is falling due to a mix of habitat loss, climate change, and the use of pesticides, resulting in devastating effects on biodiversity and food production.
The Problem of Bee Decline
The decline in bee populations is a significant issue, with around 90% of flowering plants depending on pollinators. In Great Britain, the population of flying insects has decreased by around 60% in the past 20 years. However, it is feared that not enough comprehensive research is being carried out to understand the problem or find solutions.
Methodology of the Study
Researchers at Kew’s "Wild Botanic Garden" in Sussex have started placing advanced bioacoustic sensors in trees to determine which bees prefer. The sensors listen to the buzz created by the wing beats of bees and build heat maps of the most popular areas. The study involves eight different tree species, including horse chestnuts and lime trees, with a mixture of local and non-local species.
Importance of the Study
The head of pollination research, Dr. Janine Griffiths-Lee, emphasizes the importance of the study, stating that the decline in pollinators is having a significant impact on crop production and ecosystem services. The study aims to provide valuable insights for urban planners, helping them to determine which trees to plant in built-up areas to combat the decline in bee numbers.
Natural Solutions for Climate Change
The director of Wakehurst, Susan Raikes, describes the 535-hectare estate as a "living laboratory" and highlights the importance of finding natural solutions to the effects of climate change. The project is part of a broader effort to understand how climate change is impacting plants and pollinators, and to identify new pollen sources that can help support local ecosystems.
Conclusion
The study at Kew Gardens is a crucial step towards addressing the decline in bee populations and finding natural solutions to the impacts of climate change. By determining which trees are most attractive to bees, researchers can provide valuable insights for urban planners and help to support the local ecosystem. The project highlights the importance of understanding the complex relationships between plants, pollinators, and climate change, and the need for comprehensive research to address these pressing issues.
