Excessive-intensity fires in 2020 and 2021 devastated the grownup sequoia tree inhabitants globally, notably at Sequoia and Kings Canyon Nationwide Parks in Northern California.
That is likely one of the few issues that Nationwide Park Service staffers and the environmentalists who’re suing the company can agree on.
On the root of the lawsuit, filed earlier this month, is a basic disagreement over the function of high-intensity fires. The Nationwide Park Service is asking “for motion … with some degree of urgency” to reseed burned areas which might be “in any other case unlikely to get well” with out human intervention. They see these fires as a risk to the species.
Analysis ecologist Chad Hanson, nevertheless, insists that such exercise is pointless and “synthetic.” He says high-intensity fires assist regrow dying populations by clearing brush that chokes younger seedlings. Additional, the method of reseeding would entail the usage of dynamite and chainsaws, which might harm forest populations.
Hanson’s John Muir Venture together with Wilderness Watch, Sequoia ForestKeeper and the Tule River Conservancy filed the go well with towards the Nationwide Park Service to cease the company’s plan.

The grievance was added as an addendum to a earlier lawsuit towards the Nationwide Park Service meant to cease the thinning of forests to stop and reduce the severity of fires.
“I’m not precisely certain what’s occurring with the Nationwide Park Service, however the information coming after the fires is excellent,” Hanson stated. “The regeneration of the forest is on tempo to be the most effective in a long time, nevertheless it looks as if we’re allergic to excellent news.”
Hanson first visited burned areas throughout the Sequoia and Kings Canyon Nationwide Parks in late June.
Till that time, the information coming from these areas was gloomy.
A Nationwide Park Service report in June 2021 stated 10% of the world’s sequoias had been wiped out by the Fort fireplace alone. Ecologists and researchers with the U.S. Geological Survey, the U.S. Forest Service and different companies had an estimate that was almost double that, primarily based on two main fires in 2020 and 2021. They put the lack of the large bushes someplace between 13% and 19%.
Hanson disputed these figures, saying his on-the-ground surveys coupled with satellite tv for pc imagery resulted in an estimated sequoia lack of 8% over the identical interval, from 2020 to 2021.
He says that a lot of the Nationwide Park Service’s information come from “anecdotal units collected by non-scientists.”
He added that laypeople gathering the information counted bushes that had already perished from drought stress and age, and different bushes thought of useless have been nonetheless alive.
“They’re well-intentioned, for certain,” Hanson stated, “however improper.”
Sintia Kawasaki-Yee, a parks spokesperson, stated she couldn’t speak concerning the lawsuit. She did, nevertheless, strongly push again on the “non-scientific” declare made by Hanson.
“Have a look at individuals concerned within the analysis,” she stated. “They’re from USGS, UC Berkeley and numerous specialists within the subject of sequoias. This was well-researched.”
The numbers dispute extends to seedlings.
The Nationwide Park Service stated a reseeding program is required primarily based on the low common of 14,112 seedlings per acre discovered the second yr after a serious fireplace.
Hanson and different environmentalists within the lawsuit dispute that determine, saying 20,000 to 30,000 seedlings per acre have been “typical” at Redwood Mountain Grove, one in all six such groves into consideration for reseeding at Sequoia and Kings Canyon parks. Hanson stated the counting was performed all through this summer season and fall. The opposite areas embody Suwanee, New Oriole Lake, Dillonwood, Board Camp and Homers Nostril.
“Sequoia seedlings appear like shrubs,” Hanson stated, “and at these locations that have been laborious hit by fireplace, you nearly couldn’t keep away from stepping on them as a result of they have been so plentiful.”
He stated that, in some areas, the variety of seedlings rose as excessive as 150,000 to 200,000 per acre. He stated he pointed that out to Clayton Jordan, superintendent of Sequoia and Kings Canyon Nationwide Parks, on a visit to Redwood Mountain Grove in September.
If the lawsuit is profitable, it might cease the Nationwide Park Service from authorizing the usage of dynamite, chainsaws and mule trains to succeed in distant areas for reseeding.
Sam Hodder, president and chief govt of the Save the Redwoods League conservation group, stated he understood the “emergency” that created the necessity to reseed.
“We’ve misplaced 19% of big sequoias in simply two years,” he stated. “That alone established a way of urgency.”
Hodder, who shouldn’t be related to the lawsuit, stated he wouldn’t touch upon its deserves, however he stated he discovered it “regrettable” that “repeated lawsuits that get dismissed are slowing down the method.”
“We firmly help our public company companions to advance this work,” he stated.
