Longtime environmental activist Idaho Lorax dies at 74

POCATELLO, Idaho (KIFI) — Longtime Idaho environmental advocate Carta Reale Sierra, commonly known as the Idaho Lorax, has died at age 74. His passing on June 9, 2026, was first reported by the Idaho State Journal and later confirmed via an online obituary shared by Rez Radio Fort Hall.

His online obituary describes him as “one of Idaho’s most unforgettable educators, entertainers, passionately eccentric public activists, and fiercely independent politicians.”

Beyond activism, Sierra was a persistent figure described as a "relentless disruptor" in local politics, running for public office multiple times. Most recently, he launched a campaign for the U.S. House of Representatives to represent Idaho's 2nd Congressional District as a member of the Constitution Party.

“Channeling Dr. Seuss, he adopted the name 'Idaho Lorax,' believing deeply in speaking up for what cannot defend itself,” states his obituary.

To honor his life and legacy, an informal gathering will be held at Lookout Point in Historic Downtown Pocatello on Saturday, June 13, from 2:00 to 5:00 PM.
