Fire Ecology

Defending Bedrock Environmental Laws and Policies

Fire is a natural force that has shaped the biodiversity of dry forests across the West for millennia. Fire is only catastrophic when it destroys homes or results in loss of life. Unfortunately, fire has been used as an excuse for opening up millions of acres of public lands to unabated logging based on the false premise that logging can prevent future fires and is needed to “restore” forests that have burned. We have chosen to work on fire as a key- stone ecological process because there is much public concern about whether it will increase during a warming climate and whether it is a significant source of CO2 emissions.

For over a decade, Geos Institute has been playing a leadership role in bringing cutting-edge science on the ecological importance of fire featured in top tier science journals, news media reports, and in efforts by partners to defend landmark environmental laws and policies. We continue to develop scientifically sound alternatives that advocate for let-burn policies under safe conditions in the backcountry and fuels reduction near homes and in flammable tree plantations.

A New Climate- and Human-Influenced Wildfire Era for Western Forests

By Dominick DellaSala, Ph.D.

2014 Meadow Fire, Yosemite National ParkWildfires are greatly impacting human communities in the West that every summer face the prospects of loss of life, homeowner damages, and smoke-filled skies. Legislators and many managers believe wildfire intensity and occurrence can be greatly reduced by removing environmental safeguards to allow more logging in the backcountry to avoid wildfire “disasters.”

Wildfires are not ecological catastrophes, rather, they are a keystone natural disturbance agent that has maintained the biologically rich and fire-adapted web-of-life in forests of the western United States for millennia. Wildfire area burned, size of large wildfires (>1,000 ac), and length of the fire season have been increasing in recent decades and these increases are at least partially attributed to the emergence of a new fire-climate era that is interacting with human-caused wildfire ignitions and logging related conversion of native fire-resilient forests to flammable tree plantations.

Proposals to radically increase logging of native forests to reduce “fuels” will not achieve their desired outcomes but instead may increase wildfire risks and impair the adaptive capacity of forests to respond to cumulative disturbances in a rapidly changing climate. Responsible wildfire management and climate change policies are needed to:

  1. reduce greenhouse gas emissions from fossil fuel burning while storing more carbon in forest ecosystems;
  2. prioritize vegetation treatments in “fire-sheds” closest to homes;
  3. redesign the built environment with wildfire safety in mind, including limiting ex-urban sprawl, and
  4. manage wildfires for ecosystem benefits under safe conditions.

Scientists fight for wildfire-burned land amid logging threat

Published by The Guardian, November 15, 2017

The US cashes in on timber from ‘devastated’ areas – but the land is actually ‘the rarest and most biodiverse habitat in the Sierra Nevadas’, says an expert

Less than a mile from Yosemite national park, Chad Hanson is wading through a sea of knee-high conifers that have burst from the ashes of the vast 2013 Rim fire. The US Forest Service essentially says the baby trees don’t exist.

The agency says that “catastrophic” fires have “devastated” parts of the forest, painting an eerie picture of swaths of blackened tree trunks like something out of a Tim Burton film.

But the vibrant green pines, firs and cedars surrounding Hanson among the patches burned during California’s third-largest wildfire tell a different story.

The Damage Done - a two-part series on the Chetco Bar fire (Jefferson Public Radio)

Restoration efforts in the Chetco Bar fire in southwest Oregon are getting underway. While most of the area was lightly burned or even unburned, more than a third of the acreage suffered severe or moderate tree damage.

Federal forest managers are gearing up to authorize salvage logging in some of the more badly-burned areas. Local elected officials are pushing hard for cutting those trees. But others question whether the long-term costs outweigh the short term benefits.

The Chetco Bar fire in southwestern Oregon was the state’s biggest wildfire of 2017, burning just over 191,000 acres, mostly in the Rogue River-Siskiyou National Forest. Seven homes were lost and hundreds of people had to evacuate from Brookings and nearby communities.

Summer of Fire, Smoke and Ash

Why has this year's fire season in the West been so intense? Is this a precursor of what is becoming the new normal?

On Monday October 16, Dominick DellaSala was a guest on KBOO's Locus FocusLocus Focus. In previous conversations they stressed the important role that fire plays in ensuring healthy forest ecosystems. But after this summer of fire, smoke and ash across the Pacific Northwest, and now Northern California, how do we reconcile our understanding of the need for forests to burn from time to time, with the horrific realities now in our faces.
