The survey on values, objectives, beliefs, and attitudes, implemented as a module of the National Survey on Recreation and the Environment, asked over 7,000 respondents nationwide about their values with respect to public lands, objectives for the management of these lands, beliefs about the role the USDA Forest Service should play in fulfilling those objectives, and attitudes about the job the agency has been doing. This report - one of a series of similar regional reports - shows respondents from the South (USDA Forest Service Region 8: Alabama, Arkansas, Florida, Georgia, Kentucky,...

A telephone survey of selected forest seedling nursery managers was conducted in early 2004. About 2 dozen managers were contacted and asked to respond during a brief (15 to 30 minute) conversation about the current practices they employ to manage root and shoot growth of hardwood seedlings. The participants involved were evenly split between public agencies (government) and private agencies (forest industry or other corporate entities). To receive open and honest responses to all questions, individual nursery names, locations, and managers were kept confidential.Individual papers from...

Cover crops are as essential a practice in hardwood production as in pine production or any other nursery operation. Without proper cover crop rotation in a nursery plan, we open ourselves up to an array of problems: more diseases, wrong pH, more weeds, reduced fertility, and less downward percolation of soil moisture due, in part, to compaction.Individual papers from this publication

The first rule of tinkering is to save all the parts, according to forester, philosopher, and hunter Aldo Leopold. Leopold was thinking about wildfire 50 years ago when he also was questioning his own role in exterminating large predators, wondering how their removal might affect forest ecosystems in the future. Leopold was well ahead of his contemporaries in ecological thought. Like predators, fire cleans and regenerates the systems it touches. A generation later, we're seeing the dramatic consequences of excluding fire from fire-adapted ecosystems. This brochure discusses what you can...

This report describes a new set of standard fire behavior fuel models for use with Rothermel's surface fire spread model and the relationship of the new set to the original set of 13 fire behavior fuel models. To assist with transition to using the new fuel models, a fuel model selection guide, fuel model crosswalk, and set of fuel model photos are provided.

The Smoke Impact Spreadsheet (SIS) is a simple-to-use planning model for calculating particulate matter (PM) emissions and concentrations downwind of wildland fires. This fact sheet identifies the intended users and uses, required inputs, what the model does and does not do, and tells the user how to obtain the model.Other publications in this series

In 1992 Charles H. Lowe proposed a major partition in the distribution of the herpetofauna of southern Arizona and New Mexico between the Madrean Archipelago and the Rocky Mountains along a line that parallels the present-day Interstate 10. We categorized species by elevation and geographic region and used spatial analysis to explore the existence and location of a Madrean Line. We found a difference in area occupied by species north and south of Interstate 10, and located a clear boundary where Lowe’s predicted line occurs. In addition, we found a very strong east (Chihuahuan Desert) and...

Information about avian responses to fire in the U.S. Rocky Mountains is based solely on studies of crown fires. However, fire management in this region is based primarily on studies of low-elevation ponderosa pine (Pinus ponderosa) forests maintained largely by frequent understory fires. In contrast to both of these trends, most Rocky Mountain forests are subject to mixed severity fire regimes. As a result, our knowledge of bird responses to fire in the region is incomplete and skewed toward ponderosa pine forests. Research in recent large wildfires across the Rocky Mountains indicates...

We summarize the findings from 10 subsequent chapters that collectively review fire and avian ecology across 40 North American ecosystems. We highlight patterns and future research topics that recur among the chapters. Vegetation types with long fire-return intervals, such as boreal forests of Canada, forests at high elevations, and those in the humid Pacific Northwest, have experienced the least change in fire regimes. The spatial scale of fires has generally decreased in eastern and central North America, while it has largely increased in the western United States. Principal causes of...
