ANILCA mandates that native corporation lands receive full fire protection paid for by the federal government.  Apparently native allotments also do (but under a different authority??)

Village digs in against a fiery foe
Evacuation too expensive an option for most, so smoke-dim town eyes a runway refuge

The Alaska National Interest Lands Conservation Act, or ANILCA, requires that federal agencies fight fires on Native lands, at whatever level the Native owners request. Venetie asked that its 8 million acres be given full suppression status, Lehnhausen said.

The land threatened by the Pingo fire is precious, village resident Ricky Frank said.

"It would be a great loss" to have a fire burn through. It would kill or drive away muskrats, marten and lynx, which provide many trappers with a livelihood. The forest provides firewood and house logs. Hunters feed their families from its moose, ptarmigan and other game.

ANCSA (as amended by ANILCA)

(e) Public lands status of real property interests exempt from real estate taxes for purposes of Federal highway and education laws; Federal fire protection services for real property interests without cost. Real property interests conveyed pursuant to this chapter to a Native individual, Native group, corporation organized under section 1613(h)(3) of this title, or Village or Regional Corporation shall, so long as the fee therein remains not subject to State or local taxes on real estate, continue to be regarded as public lands for the purpose of computing the Federal share of any highway project pursuant to Title 23, as amended and supplemented, for the purpose of the Johnson-O'Malley Act of April 16, 1934, as amended (25 U.S.C.A. section 452), and for the purpose of Public Laws 815 and 874, 81st Congress (64 Stat. 967, 1100). So long as there are no substantial revenues from such lands they shall continue to receive wildland fire protection services from the United States at no cost.
