Comparing potential fuel treatment trade-off models
Understanding the trade-offs between short-term and long-term consequences of fire impacts on ecosystems is needed before a comprehensive fuels management program can be implemented nationally. We are evaluating 3 potential trade-off models at 8 locations in major U.S. fuel types. We present results of the initial testing of the 3 selected models/modelling approaches and a 4th model on the Bitterr

Introduction to fire danger rating and remote sensing - Will remote sensing enhance wildland fire danger prediction?
While ‘Fire Danger’ per se cannot be measured, the physical properties of the biotic and abiotic world that relate to fire occurrence and fire behavior can. Today, increasingly sophisticated Remote Sensing methods are being developed to more accurately detect fuel properties such as species composition (fuel types), vegetation structure or plant water content - to name a few. Based on meteorologic

Bark heat resistance of small trees in Californian mixed conifer forests: Testing some model assumptions
An essential component to models of fire-caused tree mortality is an assessment of cambial damage. Cambial heat resistance has been traditionally measured in large overstory trees with thick bark, although small trees have thinner bark and thus are more sensitive to fire. We undertook this study to determine if current models of bark heat transfer are applicable to small trees (<20 cm diameter at

Native American impacts on fire regimes of the California coastal ranges
AimNative American burning impacts on California shrubland dominated landscapes are evaluated relative to the natural lightning fire potential for affecting landscape patterns.LocationFocus was on the coastal ranges of central and southern California.MethodsPotential patterns of Indian burning were evaluated based upon historical documents, ethnographic accounts, archaeological records and conside

Alien plant species threat assessment and management prioritization for Sequoia-Kings Canyon and Yosemite National Parks
Executive SummaryThis document reports the results of alien species surveys at Sequoia-Kings Canyon and Yosemite national parks. It includes the findings of a comprehensive literature review of the biology and ecology of all alien plant species found during these surveys and the ranking of those species for prioritizing management and control programs. Surveys primarily targeted areas of human dis

Contaminant studies in the Sierra Nevadas
1. 1. Barred owls fed at a sub-maintenance (SM) level had significantly (P < 0.01) longer meal to pellet intervals (MPI)/g eaten/kg body weight (BW) than those fed at an above maintenance (AM) level; MPI/g per kg for owls fed at a maintenance (M) level was intermediate but significantly (P < 0.01) different from both SM and AM. 2. 2. During SM feeding, MPI/g per kg gradually increased. 3. 3. T
