BURNS, Ore. — The leader of an American Indian tribe that regards an Oregon nature preserve as sacred issued a rebuke Wednesday to the armed men who are occupying the property, saying they are not welcome at the snowy bird sanctuary and must leave.

The Burns Paiute tribe was the latest group to speak out against the men, who have taken several buildings at the preserve to protest policies governing the use of federal land in the West.

“The protesters have no right to this land. It belongs to the native people who live here,” tribal leader Charlotte Rodrique said.

She spoke at a news conference at the tribe’s cultural center, about half-hour drive from Malheur National Wildlife Refuge, which is being occupied by some 20 men led by Ammon Bundy, whose father Cliven was at the center of a standoff in Nevada with federal officials in 2014 over use of public lands.

Ammon Bundy is demanding that the refuge be handed over to locals.

Rodrique said she “had to laugh” at the demand, because she knew Bundy was not talking about giving the land to the tribe.

The 13,700-acre Burns Paiute Reservation is north of this remote town in Oregon sagebrush country. The reservation is separate from the wildlife refuge, but tribal members consider it part of their ancestral land.

As with other tribes, the Burns’ Paiute’s link to the land is marked by a history of conflict with white settlers and the U.S. government. In the late 1800s, they were forced off a sprawling reservation created by an 1872 treaty that was never ratified.

Some later returned and purchased property in the Burns area, where about 200 tribal members now live.

Bundy’s group seized buildings Saturday at the nature preserve in eastern Oregon’s high desert country. Authorities have made no attempt to remove them.

The Burns Paiute tribe has guaranteed access to the refuge for activities that are important to their culture, including gathering a plant used for making traditional baskets and seeds that are used for making bread.

The tribe also hunts and fishes there.

Rodrique said the armed occupiers are “desecrating one of our sacred sites” with their presence at refuge.

Bundy’s group, calling itself Citizens for Constitutional Freedom, says it wants an inquiry into whether the government is forcing ranchers off their land after Dwight Hammond and his son, Steven, reported back to prison on Monday.

The Hammonds, who have distanced themselves from the group, were convicted of arson three years ago and served no more than a year.

A judge later ruled that the terms fell short of minimum sentences requiring them to serve about four more years.
