When the Dragon Bravo and White Sage fires roared through northern Arizona last summer,
they didn't just destroy the Grand Canyon Lodge and hundreds of thousands of ponderosa pine trees.
They also affected a humble yet ecologically important native succulent, the Peridine Plains Cactus.
It's not a plant many four corners visitors are likely to notice.
Shape like a tiny green hedgehog, the Peridine Plains Cactus grows just an inch or two above the ground
and could fit in the palm of your hand.
In winter, when it's cold and dry, the entire plant often recedes underground,
lying dormant until warmer and wetter conditions return.
When Claire Aslan, an associate professor in now School of Earth and Sustainability,
heard the white sage fire had spread across much of the plant's native range,
she worried the species would suffer irreparable damage.
I knew some really high severity burns had occurred right where these cacti grow,
Aslan said.
I went up there in October, right after the fire was 100% contained.
I saw that lots of them were very charred, but to my surprise, some areas were totally black
except for these little green dots. It was the cacti. I thought, how is this even possible?
Thanks to a grant from the U.S. Forest Service, Aslan is about to find out just how resilient these
succulents can be. Over the next three years, Aslan and assistant professor Sarah Souther
will venture out to a series of white sage fireburn sites on forest service land and monitor
the life cycles of every cactus they find. While they'll take note of cacti,
that were completely charred by the fire and cacti that remain completely green, they're most
interested in the plants that have burned out are spines but remain green in the center. We're studying
those most closely to find out whether they make it in the long term, whether they regrow or not,
as land said. We'll also track reproduction. Some plants look like they're not reproducing this year,
but we'll see if that changes in the future. If it does, we'll be able to see new baby plants
appear. Aslan said the work will help the Forest Service understand which fire-burned areas need
restoration work and which are better left to regenerate on their own, allowing them to allocate
taxpayer dollars more wisely. They have to be careful with limited resources, Aslan said. If we're
seeing sites that are more resilient, that seem to be recovering just fine, they might skip
restoration in those areas and save it for other sites that need it more. But the study's
impact could extend far beyond succulence in the southwest. About a quarter of the U.S. has been in a
megadrought since the year 2000. Ecologists like Aslan have measured the effects on plants in a wide
variety of biomes, from the coast to the desert, and they're worried. There's a strong drought
response in these plants, Aslan said. Plant diversity has taken a hit. There are fewer pollinators.
A lot of the ecosystem is at its limit now. The plants don't have many free resources.
To add a big fire on top of that is incredibly damaging and could make it really hard for plants
to recover. And yet, as Aslan has seen, some plants do
recover, including some small succulents like the Paradine Plains Cactus. If ecologists can monitor
plants across all fire-prone areas and track which species do and do not recover well without
human intervention, governments can do a more effective, efficient job at preserving these
environments in the future. In lots of places, from California to Minnesota, we're getting
bigger fires and more prolonged droughts, as land said. Understanding how our plant communities can
make it through those kinds of shocks is a huge question in restoration. If we can identify sources of
resilience, we could help improve resilience across all our ecosystems. Read more stories from
