Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America.
A decline in bee population leads to a decline in crop yield, which will then result in a reduction in the food supply and cause economic hardships for farmers. [24] [25] Commercially produced B. impatiens is one of the most important species of pollinator bees that are used by greenhouse industry in North America, [7] including Canada and ...
Honey bees at a hive entrance: one is about to land and another is fanning. Colony collapse disorder (CCD) is an abnormal phenomenon that occurs when the majority of worker bees in a honey bee colony disappear, leaving behind a queen, plenty of food, and a few nurse bees to care for the remaining immature bees.

This series explores aspects of America that may soon be just a memory -- some to be missed, some gladly left behind. From the least impactful to the most, here are 25 bits of vanishing America ...
The decline was "apparent regardless of habitat type" and could not be explained by "changes in weather, land use, and habitat characteristics". The authors suggested that not only butterflies, moths and wild bees appear to be in decline, as previous studies indicated, but "the flying insect community as a whole". [1] [4] [52] [53] [54]
Ground bees are considered to be great yard aerators. Spring mining bees are also generalist pollinators, which is why they’re found on some of the earliest blooming flowers of the season.
Bombus occidentalis was once one of the most common bee species in the North West America. [4] They have been found from the Mediterranean California all the way up to the Tundra regions of Alaska, making them one of the bees with the widest range geographic range. [4] However, recently there has been a noticeable decline in population. [5]
Birds are a critical part of the ecosystem. If they can’t survive on the North American continent or in the world, other life forms may not make it either.
