A tiny cactus that survives intense wildfire could offer clues about the resilience of ecosystems on the Colorado Plateau.
The Colorado Plateau is home to eight species of pediocacti, tiny, spiny succulents able to survive drought and extreme cold in harsh, high-elevation environments.
Now, one species has become a helpful indicator of ecosystem resilience to wildfire.
The Paradine plains cactus only grows on and around the Kaibab Monocline, mostly in the pinyon-juniper habitat where high desert sagebrush transitions to ponderosa pine forest.
They're one of the first plants to flower in spring, so they're important for early pollinators.
Part of their life cycle is spent underground when the cacti retract their stems into their roots to aid survival during extended dry spells.
After the White Sage Fire burned north of the Grand Canyon in the summer of 2025, ecologists from the Center for Adaptable Western Landscapes at Northern Arizona University were quick to visit high-severity burns where the rare cacti grow.
They wanted to see whether any of the plants they'd been monitoring had survived.
Among dead trees and completely blackened ground cover, they were amazed to see patches of what looked like little green buttons.
Incredibly, around 80% of the cacti had survived.
Although, in the highest severity burns, around half had visible fire damage.
Researchers are now carefully monitoring the Paradine plains cacti population.
With their yellow bell-shaped flowers, they're the equivalent of the canary in the coal mine, indicators of the whole ecosystem's ability to endure the increasing frequency of fire in the region.
