6 Thriving or Threatened?

Why did the bee get in trouble? They weren’t bee-hiving themselves



There are many theories that explain why bumble bee populations have declined over the years. Many researchers agree that things such as use in farms and a decrease in bumble bee habitat are some of the leading causes for these population declines. When farming is conducted on a large scale we refer to this as . To make industrial agriculture efficient, large fields are planted with a single crop to make harvesting easier. This practice is called monoculture and it reduces the of an area as there is only one species of plant present as opposed to many different species like what we would see in a natural habitat.

Bumble bees depend on a wide variety of plant species for , therefore, when an entire field is planted with a crop that they are unable to forage on throughout their lifetime, they are unable to thrive in that area. Having a large diversity of flowers available for bees is essential for bumble bee survival.

As we previously mentioned in Chapter 3, such as s also have a negative impact on native bumble bee species. Non-native bees compete with bumble bees for food and other resources and they can also introduce dangerous s that can harm or kill bumble bees. When humans introduce non-native bees as pollinators for agricultural purposes or when they start a commercial beekeeping operation with honey bees, this can deter native bumble bees from that area.

Additionally, has a big impact on bumble bee survival. Fluctuating weather patterns, changing flower blooming times, and temperature extremes all influence a bumble bee’s ability to thrive.

Overall, bumble bee populations are very much at risk. Species such as the yellow-banded bumble bee and the gypsy cuckoo bumble bee in particular have been significantly impacted by human activity. It is our responsibility to do what we can to protect these important pollinators for the wellbeing of the natural environment.
