Fisheries Research Report No. 190 - Esd Reporting And Assessment Subprogram: Strategic Planning, Project Management And Adoption - Stage 2, R Fletcher
Fisheries research reports
Final FRDC Report – Project Number 2004/006
The second stage of the operation of the ESD Subprogram was successful, but compared to the focus during the first subprogram period, mostly in a consolidation manner rather than from the generation of significant new tools. This was necessary because it takes time to adopt and integrate significant changes to the methods of operation of agencies and industries. The policies must be there before any real activity can occur and we found that for the broader focused, cross fishery/cross sector applications of the framework, agencies were not in a position for much of …

The supply chains through which foods are produced, processed, and transported can have a significant impact on the environment in terms of the carbon dioxide (CO2) that is emitted during each of these phases; however, little research has incorporated information about environmental impact into supply chain scenarios. Moreover, many consumers are unaware of how their food choices may impact the environment in this way. To fill these gaps, a tool called CarbonScope was developed to show consumers the CO2 emissions associated with different food types and food transportation scenarios. A short training was designed that walks participants through various food …
Sustainable Site Remediation : A Life Cycle Assessment Approach, Harnoor Dhaliwal
Sustainable Site Remediation : A Life Cycle Assessment Approach, Harnoor Dhaliwal
Theses
Remediation of contaminated areas is often a resource-intensive activity that itself can create environmental burdens. Life cycle assessment (LCA) was used as a tool to examine the environmental impacts associated with remediation activities. A hypothetical contaminated site with five remediation alternatives was developed for this analysis. The results of Life cycle Impact Assessment (LCIA) indicated that greater site activity in terms of transportation, material and equipment use translated into higher environmental impacts.
A sensitivity analysis was performed to evaluate the environmental impacts further in different time horizons. The results showed that choice of time horizon can have a significant effect …

Natural processes tend to vary over time and space, as well as between species. The ecosystem services these natural processes provide are therefore also highly variable. It is often assumed that ecosystem services are provided linearly (unvaryingly, at a steady rate), but natural processes are characterized by thresholds and limiting functions. In this paper, we describe the variability observed in wave attenuation provided by marshes, mangroves, seagrasses, and coral reefs and therefore also in coastal protection. We calculate the economic consequences of assuming coastal protection to be linear. We suggest that, in order to refine ecosystem-based management practices, it is …

A Comprehensive Guide To Fuel Management Practices For Dry Mixed Conifer Forests In The Northwestern United States, Theresa B. Jain, Michael Battaglia, Han-Sup Han, Russell T. Graham, Jeremy S. Fried, Christopher R. Keyes, Jonathan Sandquist
JFSP Research Project Reports
This guide describes the benefits, opportunities, and trade-offs concerning fuel treatments in the dry mixed conifer forests of northern California and the Klamath Mountains, Pacific Northwest Interior, northern and central Rocky Mountains, and Utah. Multiple interacting disturbances and diverse physical settings have created a forest mosaic with historically low- to mixed-severity fire regimes. Analysis of forest inventory data found nearly 80 percent of these forests rate hazardous by at least one measure and 20 to 30 percent rate hazardous by multiple measures. Modeled mechanical treatments designed to mimic what is typically implemented, such as thinning, are effective on less than …

A Comparison Of Fire Severity Patterns In The Late 19th And Early 21st Century In A Mixed Conifer Forest Landscape In The Southern Cascades, Alan H. Taylor, Carl N. Skinner, Becky Estes
JFSP Research Project Reports
The extent and severity of fires in the United States during the last decade has been remarkable. Since 2002, there has been seven years (2002, 2004, 2005, 2006, 2007, 2011, 2012) when over 2.8 million ha have burned, more than twice the previous decade. The extent of recent fire activity has increased risks to lives and property (Cohen 2008; , biodiversity and species-at-risk (Spies et al. 2006), the timber value of forests (Butry et al. 2001) and forests as a carbon sink (Hurteau et al. 2008, 2011). Although one driver of the increase in fire extent, at least in western …

A Synthesis Of Post-Fire Road Treatments For Baer Teams: Methods, Treatment Effectiveness, And Decisionmaking Tools For Rehabilitation, Randy B. Foltz, Peter R. Robiochaud, Hakjun Rhee
JFSP Research Project Reports
We synthesized post-fire road treatment information to assist BAER specialists in making road rehabilitation decisions. We developed a questionnaire; conducted 30 interviews of BAER team engineers and hydrologists; acquired and analyzed gray literature and other relevant publications; and reviewed road rehabilitation procedures and analysis tools. Post-fire road treatments are implemented if the values at risk warrant the treatment and based on regional characteristics, including the timing of first damaging storm and window of implementation. Post-fire peak flow estimation is important when selecting road treatments. Interview results indicate that USGS methods are used for larger watersheds (>5 mi2) and NRCS …
Delivery And Demonstration Of Surface Wind Simulation Tool For Fire Management Decision Support, Mark Finney, Larry Bradshaw, Bret Butler
Delivery And Demonstration Of Surface Wind Simulation Tool For Fire Management Decision Support, Mark Finney, Larry Bradshaw, Bret Butler
JFSP Research Project Reports
One major source of uncertainty in fire behavior predictions is the spatial variation in winds blowing over mountainous terrain. Fire managers have not had access to “real time” predictions of surface wind flow. With the generous support of the JFSP and additional funding from several USDA Forest Service sources a wind simulation tool has been developed and tested. This project had three primary objectives: 1. Support wildland fire incident management teams with surface wind flow simulations. 2. Validate, improve and document the utility of gridded wind as a fire management decision support tool. 3. Produce technical documentation, including a user’s …

Characterizing Lessons Learned From Federal Biomass Removal Projects, Dennia R. Becker, Dalia Abbas, Kathleen E. Halvorsen, Pamela J. Jakes, Sarah M. Mccaffrey, Cassandra Moseley
JFSP Research Project Reports
The idea of offsetting the costs of wildfire hazardous fuels reduction treatments by selling the biomass removed is appealing. There are however challenges to biomass utilization that impedes progress. For instance, the lack of biomass processing capacity may impede progress in some regions, while in other regions an inconsistent supply of biomass available for wood products markets limits private investment. Despite efforts to increase biomass utilization, uncertainty exists of regarding the characteristics necessary to stimulate biomass utilization, effectiveness of agency and local efforts, and the role of partnerships in building the types of capacity necessary to expedite biomass removal. The …

JFSP Research Project Reports
This project provided for an improved version of the Fire and Fuels Extension to the Forest Vegetation Simulator (FFE-FVS), a program whose original development was largely financed by the JFSP. The program is widely used by JFSP member agencies and several JFSP-sponsored research projects to support analysis at the stand to large landscape spatial scales. New research results rendered version 1 obsolete and experience with the model demonstrated that some parts of it needed to be improved. Equally important are issues regarding support, training, and system usability. We conducted 42 on-site training sessions over the last 4 years and also …
Does Prescribed Burning In Southern Forests Release Significant Amounts Of Mercury To The Atmosphere?, Thomas A. Waldrop, Mac A. Callahn, John A. Stanturf
Does Prescribed Burning In Southern Forests Release Significant Amounts Of Mercury To The Atmosphere?, Thomas A. Waldrop, Mac A. Callahn, John A. Stanturf
JFSP Research Project Reports
Mercury (Hg) emissions from prescribed fire present a potential impact on air quality that could motivate regulators to further restrict prescribed burning. Atmospheric deposition of Hg (originating from industrial sources) to forests is well documented, and the prescribed burning of two to four million acres per year in the South recycles an unknown (but potentially significant) amount of Hg into the atmosphere and surface waters by volatilization and post-fire runoff. This and other environmental concerns present a significant challenge to local land managers who use prescribed fire. Our objectives were (1) to estimate local and South-wide emission of Hg due …

Effect Of Mechanical Mastication Followed By Prescribed Fire On Mycorrhizas And Hypogeous Fungi In Mixed Hardwood Chaparral, Darlene Southworth, Jennifer Gibson, Jessica Donohue, Jonathan Frank, Kate Wagner, Jason Lambert, Acacia Baldner
JFSP Research Project Reports
The purpose of this study was to examine the effects of mechanical mastication followed by prescribed fire on mycorrhizal fungi and hypogeous sporocarps. A dense fire-prone mixed hardwood-conifer chaparral comprises a significant component of vegetation at Whiskeytown National Recreation Area. Prescribed burns, as fuel reduction treatments, are limited by air quality restrictions and narrow climatic conditions appropriate for burnings. Brush mastication is a fast and inexpensive tool commonly used by land managers to reduce ladder fuels. However, a dense layer of chipped debris remains, which, when burned, heats the soil more than ladder fuels. The upper layers of mineral soil …

Effects Of Prescribed Fire On Biological Soil Crusts And Their Subsequent Recovery In A Great Basin Juniper Woodland, Steven D. Warren, Larry L. St.Clair, Jeffrey R. Johansen, Paul Kugrens
JFSP Research Project Reports
A prescribed burn was conducted in a juniper woodland approximately 40 km south of Tooele, Utah on 05 October 2006. Conditions were sub-optimal, and the fire did not encroach into mid- or late-successional areas; only the early-successional area burned successfully. This study evaluated the effects of the prescribed burn on biological soil crusts that occupy the soil surface and are important for soil stability, soil nutrient cycling, and the germination and survival of vascular plants. Biological soil crusts are composed primarily of cyanobacteria, green algae, lichens and mosses. Mosses were rare under juniper trees, so the effects of the fire …

Effects Of Fuels/Fire Risk Reduction Treatments Using Hydro-Mow Or Thinning On Pinyon-Juniper Ecosystem Components Within The Wildland-Urbaninterface., Gerard J. Gottfried, Steven T. Overby, Philip A. Kemp, Cara Macmillan
JFSP Research Project Reports
Pinyon-juniper woodlands are a dominant vegetation type throughout the Interior West on lands managed by the U.S. Forest Service and the USDI Bureau of Land Management. The woodlands have traditionally been viewed as having a low risk of wildfires because of the lack of a continuous and dense ground cover and low tree stand densities. However, stand densities are often high and are increasing in many areas and wildfires, often resulting in loss of lives and property, will occur under conditions of low humidity, high temperatures and wind speeds, and an ignition source. Woodlands commonly surround or are adjacent to …

Synthesis Of Knowledge On The Effects Of Fire And Fire Surrogates On Wildlife In U.S. Dry Forests, Patricia L. Kennedy, Joseph B. Fontaine
JFSP Research Project Reports
Dry forests throughout the United States are fire-dependent ecosystems, and much attention has been given to restoring their ecological function. As such, land managers often are tasked with reintroducing fire via prescribed fire, wildland fire use, and fire-surrogate treatments such as thinning and mastication. During planning, managers frequently are expected to anticipate effects of management actions on wildlife species. This document represents a synthesis of existing knowledge on wildlife responses to fire and fire-surrogate treatments, presented in a useful, management-relevant format. Based on scoping meetings and dialogue with public lands managers from throughout the United States, we provide detailed, species-level, …

Synthesis Of Knowledge On The Effects Of Fire And Thinning Treatments On Understory Vegetation In U.S. Dry Forests, Anne M. Bartuszevige, Patricia L. Kennedy
JFSP Research Project Reports
A century of fire exclusion in dry forests across the United States has resulted in high fuel loads and increasing dominance by fire-intolerant vegetation. Federal, state, and private agencies have adopted a goal of managing forests to reduce the risk of high-severity wildfire. Forest managers use a variety of tools to create desired conditions within forests; the most common are prescribed fire and mechanical thinning. These two treatments may be used separately or in combination, depending on restoration goals for the forest stand. Before these treatments can be applied, managers must justify their choice by documenting the effects of the …

The Joint Fire Science Program (JFSP) sponsored this study to enhance the ability of federal land managers to understand and deal with the economic and financial aspects of woody biomass removal as a component of fire hazard reduction treatments. The study objectives were to synthesize the body of economic and financial information and tools currently available to federal land managers in the West, identify managers’ information needs and disconnects from available information, and fill the gaps between existing information and tools versus managers’ awareness of available information and access to tools. The methods used for this study included 1) preparing …
Epidemic Southern Pine Beetle Attacks: A Problem Of Fuel-Loading Or An Opportunity For Management?, Thomas A. Waldrop, G. Geoffrey Wang, Knight Cox
Epidemic Southern Pine Beetle Attacks: A Problem Of Fuel-Loading Or An Opportunity For Management?, Thomas A. Waldrop, G. Geoffrey Wang, Knight Cox
JFSP Research Project Reports
The Piedmont Region of South Carolina experienced one of the heaviest attacks of southern pine beetle (Dendroctonus frontalis Zimm.) in history during the early part of this decade. Managers with both commercial objectives and restoration objectives needed information on how prescribed burning or mechanical treatments can be used to reduce the heavy fuels resulting from these attacks, without neglecting their primary management objectives. Prescribed burning is of concern because intensities are expected to be high and fires may damage soils, neighboring trees, or target vegetation. Methods of predicting fire behavior and fuel consumption are unavailable. Mechanical treatments will reduce fuels …

JFSP Research Project Reports
Dimensions, volume, and biomass were measured for 121 hand-constructed piles composed primarily of coniferous (n=61) and shrub/hardwood (n=60) material at sites in Washington and California. Equations using pile dimensions, shape, and type allow users to accurately estimate the biomass of hand piles. Equations for estimating true pile volume from simple geometric shapes and measurements of pile dimensions were also developed to allow users who require estimates of pile volume for regulatory reporting. Biomass and volume estimation equations are being programmed into a web-based calculator to allow users to estimate either value from pile dimensions.

We evaluate whether current procedures used in fire behavior prediction models such as FVS-FFE provide predictions of CBD and CBH suitable for evaluating fire behavior in response to fuel treatments. Currently, FFE-FVS uses a geographic non-specific set of tree allometries and assumes a uniform distribution of crown mass when estimating CBH and CBD. We develop allometric equations to predict crown mass specific to ponderosa pine in the Black Hills (Pinus ponderosa Dougl. ex Laws.) from a sample of 80 felled trees in 16 forest stands spanning a wide range in tree size and stand. We develop a non-uniform description of …

Ecological Effects Of Prescribed Fire Season: A Literature Review And Synthesis For Managers, Eric Knapp, Becky Estes, Carl N. Skinner
JFSP Research Project Reports
Prescribed burning may be conducted at times of the year when fires were infrequent historically, leading to concerns about potential adverse effects on vegetation and wildlife. Historical and prescribed fire regimes for different regions in the continental United States were compared and literature on season of prescribed burning synthesized. In regions and vegetation types where considerable differences in fuel consumption exist among burning seasons, the effects of prescribed fire season appears, for many ecological variables, to be driven more by fire-intensity differences among seasons than by phenology or growth stage of organisms at the time of fire. Where fuel consumption …

Reducing Fine Fuel Loads, Controlling Invasive Annual Grasses, And Manipulating Vegetation Composition In Zion Canyon, Utah, J. R. Matchett, Aviva O'Neill, Matt Brooks, Cheryl Decker, Jennifer Vollmer, Curt Deuser
JFSP Research Project Reports
Fine fuels created by non-native annual grasses are a land management problem throughout the United States and beyond. These fuels facilitate the ignition of wildfires and promote their spread, creating hazardous fuel conditions in wildland urban interface areas. For example, fine fuel accumulations from non-native annual grasses in the riparian corridor at Zion National Park threaten the few egress routes from Zion Canyon, creating a threat to human life should a large wildfire occur there. In addition, when these non-native plants create novel fuel characteristics and fire behavior, they can lead to altered fire regimes that can significantly degrade natural …

A Regional Assessment Of The Ecological Effects Of Chipping And Mastication Fuels Reduction And Forest Restoration Treatments., Mike Battaglia, Charles Rhoades, Monique E. Rocca, Michael G. Ryan
JFSP Research Project Reports
Over the past several years, fire managers have increased their use of mastication treatments, the on-site disposal of shrubs and small-diameter trees through chipping and shredding. Mastication is a relatively untested management practice that alters the chemical and physical conditions of the forest floor and may influence vegetation regrowth and fuel development for years or decades. Eighteen sites were established across four ecosystems of the southern Rocky Mountains and the Colorado Plateau: lodgepole pine (Pinus contorta), mixed conifer (Pinus ponderosa, Pseudotsuga menziesii, Pinus flexilis, and Pinus contorta), ponderosa pine (Pinus ponderosa), and pinyon pine/juniper …

The Healthy Forest Restoration Act of 2003 (HFRA) was enacted to reduce wildfire risk to communities and other at-risk lands through a collaborative process of planning, prioritizing and implementing hazardous fuel reduction projects. One of the key features of HFRA is the development of community wildfire protection plans (CWPPs). We studied the development of CWPPs in order to identify those factors and processes that consistently lead to effective collaborative fire and fuels management as defined by HFRA, and enhance local social capacity to sustain wildfire protection activities into the future. Findings from this research highlight the importance of: (1) drawing …
