“…Larger oaks trees in general are more likely to survive fires (Paysen & Narog 1993;Horney et al 2002;Swiecki & Bernhardt 2002;Regan & Agee 2004), as were the larger saplings in our study. Presumably, larger trees have thicker bark which insulates and reduces the amount of time living cells in the cambium layer are exposed to potentially lethal temperatures (Hare 1965;Plumb 1980).…”

Woodland restoration sites planted with Quercus lobata (valley oak) often have serious invasions of nonnative annual grasses and thistles. Although prescribed fire can effectively control these exotics, restoration managers may be reluctant to use fire if it causes substantial mortality of recently planted saplings. We studied the effects of prescribed fires on the survival and subsequent growth of 5-and 6-year-old valley oak saplings at a research field near Davis, California. One set of blocks was burned in summer 2003 at a time that would control yellow star thistle, a second set of blocks was burned in spring 2004 at a time that would control annual grasses, and a third set was left unburned. Very few oaks died as a result of either fire (3-4%). Although a large proportion was topkilled (66-72%), virtually all these were coppiced and most saplings over 300 cm tall escaped top-kill. Tree height, fire temperature, and understory biomass were all predictive of the severity of sapling response to fire. Although the mean sapling height was initially reduced by the fires, the growth rates of burned saplings significantly exceeded the growth rates of unburned control trees for 2 years following the fires. By 2-3 years after the fires, the mean height of spring-and summer-burned saplings was similar to that of the unburned control saplings. The presence of valley oak saplings does not appear to preclude the use of a single prescribed burn to control understory invasives, particularly if saplings are over 300 cm tall.

“…Interior and canyon live oaks sprout both from root and canopy crowns following fire. Canyon live oak bark resists low-intensity fires (Paysen and Narog 1993), whereas the relatively thin bark of interior live oak results in top-kill with all but lowest intensity fires (Plumb 1980). Both species can also sprout new branches from epicormic buds on the stem.…”

In the main forest belt of California, fires seldom or never sweep from tree to tree in broad all-enveloping sheets. .. Here the fires creep from tree to tree, nibbling their way on the needle-strewn ground, attacking the giant trees at the base, killing the young, and consuming the fertilizing humus and leaves. muir (1895) van Wagtendonk.indd 249 15/03/18 4:43 PM van Wagtendonk.indd 250 15/03/18 4:43 PM Temperature Precipitation United States LAT 38°55' N/LONG 121°05' E/193 m Auburn, CA (30-30) 16.1°C 874 mm United States LAT 38°42' N/LONG 120°02' E/2438 m Twin Lakes, CA (30-30) 4.5°C 1194 mm United States LAT 39°17'N/LONG 120°42'E/1609 m Blue Canyon, CA (30-30) 11.0°C 1641 mm United States LAT 39°23'N/LONG 120°06'E/1701 m Boca, CA (30-30) 6.2°C 570 mm FIGURE 14.1 Annual precipitation and temperature patterns for four stations along a transect from the foothills to the eastern side of the Sierra Nevada.

“…For now, the use of prescribed fire in western oaks should be approached with caution and patience. Some species are sensitive to fire (table 2-1) but may survive under certain conditions (Paysen and Narog 1993). Many oaks seem to be prone to disease, such as heart rot.…”

_____________________________________This state-of-knowledge review about the effects of fire on flora and fuels can assist land managers with ecosystem and fire management planning and in their efforts to inform others about the ecological role of fire. Chapter topics include fire regime classification, autecological effects of fire, fire regime characteristics and postfire plant community developments in ecosystems throughout the United States and Canada, global climate change, ecological principles of fire regimes, and practical considerations for managing fire in an ecosytem context.
