Many of the fires in California are not forest fires; they are mainly scrub brush (chapparel) wildfires and cannot be prevented by improved logging practices.
The Ferguson fire near and in Yosemite is a forest fire. The forests of the Sierra can be better managed. Many of the Sierra forests have been hard hit by bark beetles and there are many dead standing trees, especially around Sequoia and Kings Canyon National Parks.
Wiki: Chaparral is a shrubland or heathland plant community found primarily in the US state of California and in the northern portion of the Baja California Peninsula, Mexico. It is shaped by a Mediterranean climate (mild, wet winters and hot dry summers) and wildfire, featuring summer-drought-tolerant plants with hard sclerophyllous evergreen leaves, as contrasted with the associated soft-leaved, drought-deciduous, scrub community of coastal sage scrub, found below the chaparral biome. Chaparral covers 5% of the state of California, and associated Mediterranean shrubland an additional 3.5%. The name comes from the Spanish word for evergreen oak shrubland.
