The Biden administration called for new protections under the Endangered Species Act for an iconic bird of the Great Plains, a move with major consequences for the oil and gas industry. US Fish and Wildlife Service officials proposed listing as endangered a portion of the lesser prairie chicken's population living in Texas and New Mexico, whose range overlaps with the oil- and gas-rich Permian Basin. The agency stopped short of awarding the same protections to the birds' northern population, in Oklahoma and Kansas, on the grounds that their numbers had declined less drastically. The decision, one of nearly two dozen new conservation measures the administration has adopted in the past four months, underscores President Biden's push to unravel his predecessor's environmental policies. In a separate move, the Environmental Protection Agency abolished a rule restricting what sort of studies the agency can use in crafting public health rules.
