Mortality Assessment of Redwood and Mixed Conifer Forest Types in Santa Cruz County Following Wildfire
… Mountains burning approximately 7,819 acres. Foresters and other land managers were left with challenging decisions on how to evaluate tree mortality. Big Creek Lumber Company, California Polytechnic State University, San Luis Obispo (Cal Poly)’s Swanton Pacific Ranch (SPR), and other resource …

Holocene Fire History Reconstruction of a Mid-Evaluation Mixed-Conifer Forest in the Eastern Cascades, Washington
Fire histories of mid-elevation mixed-conifer forests (MEMC) are uncommon, particularly in the eastern Cascades of Washington. As a result, fire regimes and the effects of 20th century fire suppression in these forests are not well understood. In the summer of 2014 a 7.80 meter-long sediment core …

Forest Densification Over 85 Years in a Sierra Nevada Mixed-Conifer Forest Decreases Conifer Regeneration and Limits Survival
<p>Forest densification in response to a century of fire suppression in Sierra Nevada mixed conifer forests has decreased conifer regeneration and survival. Increases in overstory biomass and decreases in canopy heterogeneity, along with decreases in shrub cover in the understory, has created …

A Comparative Study of Tree Structure and Composition of a mixed Coniferous Forest and Sequoia Groves in Sequoia National Park, California
<p>Forest structure in the giant sequoia grove and in the surrounding mixed coniferous forest is dominated by Abies concolor. The large basal area of Sequoiadendron giganteum is significant within the grove in terms of relative dominance but does not offset the density of Abies concolor which …

Regeneration of fire-adapted species in the Sierra Nevada contingent upon repeated fuel treatments and available soil moisture
… have driven a significant fire deficit in the forests of western North America, leading to widespread changes in the composition, structure, and fuels of these historically fire-adapted ecosystems. Over the last few decades, fuel treatments have been widely applied to restore forest structure …

Using Airborne Laser Altimetry to Characterize Surface Fuels in Western Montana
Quantifying surface fuels in forests is problematic for land managers due to the difficulty in measuring fuels of different sizes and spatial variability. Estimating fuel loads is important for identifying departures from historical fire regimes, predicting fire behavior and effects, and …

Identifying the effects of land use and policy on disturbance regimes in the Teanaway Community Forest, Washington
The historic fire regime of the forests of the Eastern Cascades, Washington, has been described as one of high-frequency, low-severity fires using fire scar analysis. Over the past few centuries, the historically open, park-like ponderosa pine-dominated stands have been significantly altered due to …

The 2006 Warm Fire: effects on habitat and prey species of the northern goshawk
… of fire in Southwestern ponderosa pine and mixed-conifer forests since initiation of forest management early in 20th century changed the composition and structure of the forest habitats of the northern goshawks (Accipiter gentilis), a food-limited species of conservation concern, and the …

A Floristic Study of the Cal Poly Swanton Pacific Ranch and a New Combination in Sanicula crassicaulis (Apiaceae), Sanicula crassicaulis var. Nudicaulis
… marsh, coastal bluff, coastal prairie, riparian forest, redwood forest, mixed conifer forest and chaparral in approximate ascending order of elevation. The property extends over an elevational gradient from 0 m to 420 m (1400 ft). We documented 634 taxa at SPR. In total, 974 specimens were …
