Waldo Canyon fire scar restoration update

Waldo Canyon Fire

From the Associated Press via the The Denver Post:

The Forest Service picked this valley as a place to send heavy equipment and fight against the flooding that caused havoc below in the months after the fire. Five years later, the images of cars floating away in Manitou Springs remain unforgettable. Here in this sparse forest, water runs controlled thanks to those excavators, which stacked logs to form dams and sculpted the channel, filled with flow-slowing objects such as rocks and charred branches.

And all along it, willows were planted with the design of further stabilizing the banks. Also, the willows could provide shade. Perhaps with cooler waters, plant and animal habitats will make a suitable home again…

The hydrologist based in Colorado Springs calls this “a pilot site” — the beginning stage for a recovery tactic that could work at riparian areas across the scar. Along with the 2,000 willows planted last month in Waldo Canyon itself, thousands more seedlings could be spread in the barren landscape beyond.

The site showcases other revegetation trends across the scar: the erosion-mitigating grasses that RMFI planted over wiped-out hillsides, accompanied by the Forest Service’s dump of mulch from a helicopter. And Shipstead expects other human action here: biocontrol by releasing bugs which crave the invasive weeds that took root after the fire.

The group steps over the plant henchmen remaining — the spiky thistle and fuzzy mullien. They continue their willow count silently, nervously, it seems…

Five years after the devastation, land managers maintain a hopeful narrative. The Forest Service calls the burn scar 70 percent revegetated — a figure that does not allude to the return of the previous conifer-covered state, but to a transformed one.

The area is taking on a look it likely had centuries ago, says Pikes Peak District Ranger Oscar Martinez. Mother Nature has “reset the clock,” he says, by pulling up the aspens that long lay dormant beneath the now-destroyed pines and firs that dominated for generations in forest time. Also covering the slopes now are tangles of scrub oak; they, like aspens, were eager to make their presence known soon after the conifers departed…

A fire of Waldo Canyon’s magnitude heats the ground to a point of hydrophobicity, where instead of water being absorbed, it is repelled. Further complicating the conifers’ return is the forest’s unique soil — “calling it a soil is kind of a generous term,” Martinez says. Conservationists call Pikes Peak granite “kitty litter,” for its pebbly, porous condition, which rain had no problem moving in the days after the burn, washing the sediment into the canyon and piling it up to heights of grown men.

That phenomenon made portions of the Waldo trail disappear along its 7-mile loop. The Forest Service continues to take questions as to when the trail will reopen, and land managers say people should refine their questions, considering the trail no longer really exists. Realignment seems more than likely…

Back at the recovery site, the willow count continues. Reflecting on the restoration here and at areas across the scar going forward, RMFI’s Peterson wonders about human’s role. “We can jump-start the process,” she says, “but nature is smarter and stronger. Nature will always find a way.”
