Jul 25, 2017 · Here are some of the main threats to bees: 1. Habitat loss - less forage and shelter for bees. Changes in our land use, including insensitive urban development and intensive farming, have caused significant losses and fragmentation of pollinator-friendly habitats.
The most pressing threats to long-term bee survival include: Climate change. Habitat loss and fragmentation. Invasive plants and bees. Low genetic diversity. Pathogens spread by commercially managed bees. Pesticides
- The scourge of Varroa mites. Pollinators contribute an estimated US$235 billion to $577 billion yearly to global agriculture, based on the value of the crops they pollinate.
- Pesticide microdoses. Pesticides also harm bees, particularly products that cause sublethal or chronic bee health issues. Sublethal pesticide exposures can make bees less able to gather forage, grow healthy larvae and fight off viruses and mites.
- Junk food diets. Like many other species, bees are losing the habitat and food sources that they depend on. This is happening for many reasons. For example, uncultivated lands are being converted to farmland or developed worldwide.
- Climate change is a force multiplier. Researchers don’t know exactly how climate change will affect bee health. But they suspect it will add to existing stresses.
Britain’s bees are in trouble. 35 UK bees species are under threat of extinction, and all species face serious threats. Pesticides are one of the key threats to bees. The decline in bees' diversity and abundance would have a serious impact on how the natural world functions, including our crops.
Nov 20, 2020 · Loss of British bees threatens food security. World's biggest bee found alive. Current Biology. Some bee populations, such as bumblebees in Europe and North America, are well studied. But in...
Apr 29, 2024 · Wild bees face risks from domesticated bees, habitat loss, and climate change. Supporting bee diversity in Ontario is an important component of promoting a healthy environment.
Bees in a modern, industrialised world are facing a range of complex and interacting threats, and the cumulative effect of which could affect the abundance and diversity of bee species. The IUCN list shows that as many as 24% of Europe’s bumblebee species are now threatened with extinction, despite being worth a staggering £690 million per ...
