The White House has set up a taskforce to tackle the decline of honey bees.
The Environmental Protection Agency (EPA) and the agriculture department will lead the effort, which includes $8m (£4.7m) for new honey bee habitats.
Bee populations saw a 23% decline last winter, a trend blamed on the loss of genetic diversity, exposure to certain pesticides and other factors. A quarter of the food Americans eat, including apples, carrots and avocados, relies on pollination.
Honey bees add more than $15bn in value to US agricultural crops, according to the White House.
The decline in bee populations is also blamed on the loss of natural forage and inadequate diets, mite infestations and diseases.
There has also been an increase in a condition called colony collapse disorder (CCD) in which there is a rapid, unexpected and catastrophic loss of bees in a hive.
But other North American pollinators, like the monarch butterfly, have seen decreases in their populations as well.
