Perhaps you've been reading that the Trump administration wants to make it easier to eliminate polar bears, spotted owls and other species from the face of the earth. As ever in Donald Trump's Washington, the reality is different, so allow us to explain.

The uproar concerns a proposed new rule to revise some practices under the 1973 Endangered Species Act. For all the praise liberals shower on that law, it has achieved far less than advertised. A 2018 report from the Heritage Foundation's Robert Gordon found that since 1973 the ESA has helped to recover only 40 species, and nearly half of those were mistakenly listed in the first place.

Meanwhile, the law has become a legal weapon to strip property rights and block millions of acres from private development. Congress ought to rewrite the ESA but can't break a partisan impasse. So this week Interior Secretary David Bernhardt tried to clarify regulation under the law to prevent abuses.

The new rule restores Congress's original two-tiered approach, killing the Fish and Wildlife Service's "blanket rule" that treated "endangered" and "threatened" species alike. This will devote scarce government dollars — and landowner attention — to the species most at risk. It will also provide states more flexibility to assist species that are struggling though not seriously endangered.

The rules clarify vague terms such as "the foreseeable future" to mean only as far as the government can "reasonably determine" a danger of extinction. This will make it harder for activists to use claims of future climate damage to declare many more species endangered.

And the rules remind regulators they must use the same five criteria in deciding whether to delist a species as they did when listing one — destruction of habitat or range; overutilization; disease; inadequate regulation; or other natural or man-made factors. This will guard against special interests that move the goalposts every time a recovered population is proposed to be cleared.

The goal of all this is to return to a rules-driven, scientific approach to species management.
