main objective of this effort is to get an better idea of the amount of
honey bee colonies losses over the states during the timespan of 1
The second objective is finding out how much impact different stressors have on honey bee colonies.
The third aim is searching for any relations between stressors and losses.

1/ January 1 colonies plus all colonies moved into that state during the quarter.
2/ Percent lost is the number of lost colonies divided by maximum colonies except for the United States, where percent lost is the number of lost colonies divided by the January 1 colonies.
3/ Defined as any surviving colony that was requeened or received new honey bees through nuc or package.
4/ Percent renovated is the number of renovated colonies divided by maximum colonies except for the United States, where percent renovated is the number of renovated colonies divided by the January 1 colonies.

Note the big increase in colonies during the Q1 in California: from 1.150.000 to 1.540.000. In February the almond trees in California have their blossom season, however the local bee population is too small for a full pollination. So they have to attract many non-local bee colonies. Bee colonies are transported from state as far as Michigan. These transports induce stress to the bees: temperature differences, fuels and vibrations. In 2019 a study found that esp. temperature differences are a factor in CCD, colony collapse disease.
Let's see if we can visualize these movements.
California has an armada of bee colonies, and this is also the case for some other southeners like Texas, FL and GA.
In the North is Idaho the top colony keeper, followed by Oregon and ND.
