The U.S. Department of Agriculture has announced that it’s suspending tracking the plunging honeybee population because of a budget shortfall.

The department will suspend data collection for its Honey Bee Colonies report, and officials did not say when — or if — it would be restarted. It will release data already collected from January 2018 through April of this year.

The Agricultural Department has been a key source of data on the insects, which is critically important to scientists and farmers.

The number of honey bee hives, vital to pollinating crops for the agricultural industry and other plants for wildlife, plummeted from 6 million in 1947 to 2.4 million in 2008. The worst honeybee hive loss on record occurred last winter as beekeepers reported a 40% loss of their colonies over the year.

Critics say the USDA’s move is the latest evidence of the Trump administration’s war on science, and its goal of suppressing information about serious environmental harms increasing under Donald Trump’s presidency.

“This is yet another example of the Trump administration systematically undermining federal research on food safety, farm productivity and the public interest writ large,” Rebecca Boehm, an economist at the Union of Concerned Scientists, told CNN.

Ironically, Vice President Mike Pence’s wife, Karen, gushed last month about National Pollinators Week and bragged about hives at the Pence residence.
