Disequilibrium of fire-prone forests sets the stage for a rapid decline in conifer dominance during the 21st century Authored by J. Serra-Diaz; Published The impacts of climatic changes on forests may appear gradually on time scales of years to centuries due to the long generation times of trees.
Consequently, current forest extent may not reflect current climatic patterns. In contrast with these lagged responses, abrupt transitions in forests under climate change may occur in environments where alternative vegetation states Fire science projects influenced by disturbances, such as fire.
The Klamath forest landscape northern California and southwest Oregon, USA is currently dominated by high biomass, biodiverse temperate coniferous forests, but climate change could disrupt the mechanisms promoting forest stability e.
Such shifts were widespread under the warmer climate change scenarios RCP 8. Our results demonstrate that major Fire science projects ecosystem shifts should be expected when climate change disrupts key stabilizing feedbacks that maintain the dominance of long-lived, slowly regenerating trees.
Zander Evans, Forest Stewards Guild Millions of acres of fuels reduction treatments are being implemented each year in the fire adapted forests of the US. Typical these fuel reduction treatments target small diameter trees for removal producing large amounts of unmerchantable woody material and elevating surface fuel loadings.
Often this material has no market value and is piled by hand or with heavy machinery and burned on site. We examined the effects of time since construction i. The webinar will also touch on pile decomposition rates and unplanned fire in areas with piled fuels.
Policy Design to Support Forest Restoration: Schultz; Published To address rapid change and complex environmental management challenges, governance approaches must support collective action across actors and jurisdictions, and planning at appropriate spatial extents to affect ecological processes.
Recent changes in U. Based on interviews with agency personnel and partners, and a survey of agency staff members, we investigated how two new policy approaches affected the governance of forest restoration and also looked at the other factors that most significantly affected policy implementation.
Our findings reveal that, under these policies, multi-year funding commitments to specific landscapes, combined with requirements to work collaboratively, resulted in larger scales of planning, improved relationships, greater leveraged capacity, and numerous innovations compared to the past.
A history of collaborative relationships, leadership, and agency capacity were the most significant variables that affected the implementation of policies designed to support collaborative landscape restoration.
Our findings suggest that policies that provide focused investment to undertake landscape approaches to restoration, along with specific requirements for interagency and partner collaboration, are yielding positive results and may represent a new era in forest policy in the United States.
How does forest recovery following moderate-severity fire influence effects of subsequent wildfire in mixed-conifer forests?
Collins; Published Given regional increases in fire activity in western North American forests, understanding how fire influences the extent and effects of subsequent fires is particularly relevant.
Remotely sensed estimates of fire effects have allowed for spatial portioning into different severity categories based on the degree of fire-caused vegetation change. In this paper, we investigated how burned areas in this broad category of moderate-severity fire fared when reburned by a subsequent fire.
We used plot-based measurements of trees and shrub cover to develop 15 forest structure and composition variables to attempt to explain observed reburn severity. His research during the last 25 years has focused on the effects and interactions of fire disturbance, climate, and people on forest dynamics at various time scales, and on the influence of understory plants on tree regeneration.
Alan presented on "Humans modulate fire regimes, forest characteristics, and fire-climate relationships in California Montane Forests.The Northwest Fire Science Consortium works to accelerate the awareness, understanding, and adoption of wildland fire science.
We connect managers, practitioners, scientists, and local communities and collaboratives working on fire issues on forest and range lands in Washington and Oregon.
Emergency Management Resources Emergency Management. Emergency Management is a publication aimed at public safety and emergency management professionals and covers trends and issues dealing with areas such as disaster preparedness, infrastructure protection, and training.
Here is a collection of elementary science projects. These experiments were selected for the relatively short time it takes to complete one, for scientific value, and for fun value.
The Rim Fire was a massive wildfire that started in a remote canyon in Stanislaus National Forest in ashio-midori.com portion of the central Sierra Nevada spans Tuolumne and Mariposa counties. The fire started on August 17, during the California wildfire season. It was the fourth-largest wildfire in California's history, having burned , acres ( sq mi; 1, km 2). Need it Fast? Select from the projects that are in bold font. Select your science project topic and then click on that to access the introduction page. Science projects for kids are supposed to be able to give details concepts of science in a simple way and the projects should be easy enough that they could be performed by kids themselves. Materials or the equipment used should be accessible easily and the experiments should be protected.. Google Science Fair is a global online competition open to individuals or teams from 13 to 18 years old.
Welcome to the Forensic Institute for Research and Education (FIRE) website. As a board certified forensic anthropologist, I have over thirty years of experience as a forensic educator and practitioner in settings involving skeletal crime scenes and analysis.
Part of the Joint Fire Science Program, we share wildland fire science information among federal, tribal, state, local, and private stakeholders in Washington and Oregon.
