The massive die-off of conifers in the Sierra Nevada between 2012 and 2018 was predictable and unprecedented. Sadly, it is also likely to happen again, said UC Cooperative Extension forestry advisor Susie Kocher.

To help landowners manage forests in a way that minimizes the risk of such catastrophic tree die-off and the threat of uncontrolled wildfire, Kocher and two colleagues produced a 20-page publication that summarizes current research on tree mortality and outlines actions that can be taken to make the forest more resilient. The publication, Mass Tree Mortality, Fuels, and Fire: A Guide for Sierra Nevada Forest Landowners, is...

For millennia, fires periodically burned through California forests, thinning trees, reducing shrubbery and clearing out downed branches and debris. Without periodic fire, the forests became more dense, with spaces between large trees filling in with a thick carpet of duff, seedlings and shrubs.

As a result, today's forests are prone to more intense and damaging fires, like the Rim Fire, King Fire, and — most recently — the Camp Fire in Butte County. These fires are burning with unprecedented severity and speed, threatening large swaths of forest, towns, and even urban areas.

Using fire as part of forest management is not a new concept. Native Americans...

The humble rake has been in the spotlight in recent weeks, and its role as a forest management tool ridiculed and scorned. However, most fire professionals believe rakes are a necessary part of saving California's forests.

Those who are familiar with fire are undoubtedly familiar with the McLeod, which is a standard firefighting tool and … it is essentially a rake (one side is a rake with coarse tines and the other side has a flat sharpened hoe). The McLeod was created in 1905 by a U.S. Forest Service ranger who wanted a single tool that could rake fire lines (with the teeth) and cut branches and roots (with the sharpened hoe edge). The McCleod is used to scrape fuels...

To reduce the dry grasses and shrubs that can fuel intense wildfires, California landowners and land managers are invited to attend a prescribed-fire workshop organized by University of California Cooperative Extension in October. The workshop will be offered in two locations – Placer County and Calaveras County.

On Oct. 2, the prescribed-fire workshop will be held at Colfax Veterans Memorial Hall, 22 Sunset Circle, Colfax. 

On Oct. 4, the workshop will be held at Ebbett's Pass Fire District, 1037 Blagen Road, Arnold. 

The one-day workshop is designed for landowners and land managers who want to learn skills in prescribed-fire planning...
