Evaluating Postfire Seeding Treatments Designed To Suppress Cheatgrass (Bromus Tectorum) In A Ponderosa Pine Forest On The Colorado Plateau, Matthew L. Brooks, Robert Klinger, Jennifer Chase, Curt Deuser

Joint Fire Science Program Research Project Reports

The restoration of historical fuel conditions and fire regimes is one of the primary land management goals in the Shivwits Plateau region of northwestern Arizona. Fire is the primary tool used in this region to reduce fuel loads and shift landscapes back to historical conditions of a low intensity, 8- 15 year return interval, surface fire regime. However, the invasive plant cheatgrass has become the dominant understory vegetation and fuel type following initial fire treatments in many areas. There is significant concern that repeated burning at historically appropriate fire return intervals for ponderosa pine forest will benefit this invasive plant …

Evaluating Approaches To Mapping Burn Probabilities For A Quantitative Wildland Fire Risk Analysis Framework., Carol Miller, Marc Parisien, Alan Ager, Mark Finney

Joint Fire Science Program Research Project Reports

This final report summarizes a collaboration that brought together experts in burn probability (BP) modeling and wildland fire risk analysis to compare and evaluate BP models, and ultimately incorporate these into a risk analysis framework. The project built on and extended the work from JFSP project #01-1-1-05. This project evaluated and tested three different independent models that generate BP maps as output for their operational use in risk analysis. The project quantified the relative sensitivity of the three BP models to different inputs, enhanced our understanding of the factors that affect BP at the landscape scale, and yielded concrete improvements …

Burning And Bats: Fire’S Effect On The Endangered Indiana Bat, Christina Frame

Joint Fire Science Program Briefs (2007-2012)

The spring prescribed burn window in the Central Hardwoods is short (usually April) and good burning days are few. The Daniel Boone National Forest (DBNF) prescribed fi re program is trying to regenerate oak ecosystems ahead of the arrival of gypsy moths in the region and the high overstory oak mortality that can result. If the burn window could be extended into the growing season (later spring), managers could control vegetation more effectively. However, the DBNF also serves as warm-season roosting habitat for the endangered Indiana bat, so burning into the growing season could potentially put the bats—and especially maternity …

A Gust Changes Everything: Local Wind Information In Unprecedented Detail With Windwizard And Windninja, Marjie Brown

Joint Fire Science Program Briefs (2007-2012)

Fire behavior model accuracy has suffered from a lack of specific information about how winds shift in direction and speed in mountainous terrain at fine scales. Before this project, fire managers lacked a tool that could provide realtime status of changing wind conditions at the scale of a specific ridge or drainage. This project resulted in two wind simulation tools that focus on this critical need: WindWizard and WindNinja. WindWizard, based on commercial computational fluid dynamics software, comes with a price tag and is computationally slower due to the complexity of the calculations it performs. WindNinja was developed as WindWizard’s …

Nebraska Statewide Forest Resource Assessment & Strategy - 2010, Scott Josiah, John Erixson

Nebraska Forest Service: Publications

This Assessment relies heavily on the input from our partners. To complete the Assessment, we bolstered our own forest resource data with publicly available data from a variety of sources, including the National Land Cover Dataset, USFS Spatial Analysis Project, U.S. Census Bureau, Nebraska Game and Parks Commission, Nebraska Department of Roads, Nebraska Natural Resources Districts and input from many partners. Combined, this information provided us with valuable insights about the nature, complexity and value of our forest resources, and helped us identify priority forest areas across the state.

Using the information from the Assessment, we developed strategic goals based …

Stand Conditions Immediately Following A Restoration Harvest In An Old-Growth Pine-Hardwood Remnant, Don C. Bragg

Journal of the Arkansas Academy of Science

Portions of the Levi Wilcoxon Demonstration Forest (LWDF), a privately owned parcel of old growth pine and hardwoods in Ashley County, Arkansas, were recently treated to restore conditions similar to some historic accounts of the virgin forest. Following a hardwood-only cut, a post-harvest inventory showed that the number of tree species in the sample area declined from 24 in 2006 (the most recent pre-harvest inventory) to 12 in 2009. Loblolly (Pinus taeda L.) and shortleaf (Pinus echinata Mill.) pine now comprise 59.2% of the remaining live trees, up from 16.2% in 2006. Between 2006 and 2009, basal area dropped from …
