The chart illustrates the number of honey bee colonies and the amount produced in the US from 1970 to 2000. The number of honey-bee colonies were shown at the left chart.
In 1970, there were four million honey-bee colonies and the next ten years, this increased approximately 4, 2 millions. However, in 1990, the number of one fell to 3, 5 millions colonies, and then this decreased every ten years. Finally, in 2010, the number of colonies reached just under 2 millions.
During the same periods, the amount of honey production were 130. 000 tonnes in 1970 and dropped to 70. 000 tonnes in 2010. But between 1980 and 1990, the amount of production of honey were increased about 10. 000 tonnes (from 110. 000 tonnes went up to 120. 000 tonnes production).
In conclusion, there was decreasing in the number of honey bee colonies and their production in 40 years.
