A proposed change to the Endangered Species Act has local environmental groups worried.

The U.S. Fish and Wildlife Service and National Oceanic and Atmospheric Administration are looking to repeal the definition of the word “harm,” which specifies protections under the act. While it might seem like a minor change, opponents say it will put habitat critical to the survival of endangered and threatened species at risk.

“If you were to put it in human terms, it’s just like saying it’s OK if they take your house, your clothing, your food, your shelter, as long as they’re not eliminating you. It’s kind of harder to survive without those basic things being met,” said Steve Manlow, executive director for the Lower Columbia Fish Recovery Board.

The Trump administration wants to rescind the current definition, claiming the Fish and Wildlife Service’s interpretations have expanded beyond the Endangered Species Act’s reach. The current definition prohibits any activity that would “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture or collect” an endangered species, including harm or damage to a species’ habitat. The Trump administration says the federal law only prohibits the capture or killing of wild animals.

Manlow said the fish recovery board’s goal is to recover salmon and steelhead populations to healthy and harvestable levels, and that the federal statute is crucial to those recovery efforts.

“Animals are no different, they just have different basic life needs. When it comes to fish, you have got to have food, you have got to have cool water, you have to have gravel coming in and places for the juveniles to rear,” he said.

Manlow said the federal government’s proposed change is an unprecedented and narrow interpretation of the Endangered Species Act, one that does not align with prior legal findings.

Among the more than 1,500 threatened or endangered species — including mammals, birds, plants, insects, amphibians and reptiles — on the federal list, an estimated 18 species can be found in Clark County.

Along with more commonly known species like coho, chinook and chum salmon, and the northern spotted owl are less well-known species, including the yellow-billed cuckoo and streaked horned lark (birds), the Nelson checker-mallow and golden paintbrush (plants), northwestern pond turtle and Suckley’s cuckoo bumblebee.

While the bald eagle was removed from the federal list in 2007, the species remains protected under the Bald and Golden Eagle Protection Act and Migratory Bird Treaty Act.

Noah Greenwald, endangered species director for the Center for Biological Diversity, said the Endangered Species Act definition for harm dates back to the 1970s when it was defined as habitat modification.

“It was further refined during the Reagan administration as significant habitat modification or degradation that leads to actual injury or death,” he said. “That’s the main way that the Endangered Species Act protects habitat for listed species is through that prohibition on take, including harm,” he said.
