Developing A Science Integration Strategy For Jfsp, Jamie Barbour
Developing A Science Integration Strategy For Jfsp, Jamie Barbour
Joint Fire Science Program Research Project Reports
The mission of the Joint Fire Science Program (JFSP) is to produce high quality research findings to inform wildland fire and fuel managers’ decisions. Since its inception in 1998, the program has funded nearly 400 studies and has generated a tremendous amount of information and analytical tools. As the JFSP moves into the future, a Science Delivery Strategy is needed to: 1) ensure that this base of information finds application, and 2) create a more systematic way to identify and organize new work that will encourage its rapid assimilation by the management community. The attached Science Delivery Strategy was developed …

Joint Fire Science Program Research Project Reports
The objective of this paper is to present recommendations for fuels treatments in ponderosa pine forests in the Southwest, Colorado Front Range, and Black Hills of South Dakota. We have synthesized existing knowledge from the peer-reviewed literature and administrative studies and acquired local knowledge through a series of discussions with fuels treatment practitioners. We describe specific treatments, the circumstances under which they can be applied, and treatment effects. We provide recommendations related to where, how, and how often fuels treatments may be prescribed to achieve desired outcomes. Desired outcomes address social, political, economic, and ecological factors.
Soil Response To Season And Interval Of Prescribed Fire In A Ponderosa Pine Forest Of The Blue Mountains, Oregon, D. Zabowski, W. G. Thies, J. Hatten, A. Ogden
Soil Response To Season And Interval Of Prescribed Fire In A Ponderosa Pine Forest Of The Blue Mountains, Oregon, D. Zabowski, W. G. Thies, J. Hatten, A. Ogden
Joint Fire Science Program Research Project Reports
Soil properties were examined at a season of burn and burn interval study located in the Malheur National for responses to prescribed burns used to reduce fuel loads and wildfire hazard. Prescribed burn comparisons included spring vs. fall burning, with either one 15-year interval burn or two 5-year interval burns of each season. Results showed that major change to soil organic matter was a reduction in the amount of O horizon. The percent bare ground increased with both spring and fall burning and was highest with multiple burns, indicating a loss of O horizon cover. There was also a decrease …

Effects Of Fuel Treatments And Wildfire On The Avifauna Of The Pine Rockland Ecosystem In Southern Florida., John D. Lloyd, Gary L. Slater, Skip Snow, James R. Snyder
Joint Fire Science Program Research Project Reports
The response of plants and animals in the pine forests of southern Florida to variation in fire and hydrological regimes remains inadequately described, hindering the ability of resource managers to manipulate fire and water to achieve desired ecological outcomes. In this study, we took advantage of natural variation in two measures of fire history (the number of days since last fire and the number of times an area had been burned during the previous ten years) and one measure of hydrology (water table elevation) to explore how plants, breeding birds, and wintering birds in slash-pine (Pinus elliottii var. densa) forests …

Effects Of Fire On Kuenzler’S Hedgehog Cactus (Echinocereus Fendleri Var. Kuenzleri), David B. Wester, Colton M. Britton
Effects Of Fire On Kuenzler’S Hedgehog Cactus (Echinocereus Fendleri Var. Kuenzleri), David B. Wester, Colton M. Britton
Joint Fire Science Program Research Project Reports
Kuenzler’s cactus (Echinocereus fendleri var. kuenzleri [Castetter, Pierce and Schwerin] L. Benson]) is a federally- and state-listed endangered species that is known to occur in pinyon-juniper habitat in the mountains of south central New Mexico in Lincoln, Otero, Chaves and Eddy counties. Presence of this species affects the management of its habitat with prescribed burning. However, there has been no research that has documented the response of Kuenzler’s cactus to fire. This project was initiated in 2002 to provide information on habitat characteristics of Kuenzler’s cacti and to investigate its response to fire. Because of the protected status of the …

We evaluated effects of an experimental fuels reduction program on elk, mule deer, and their habitat at the Starkey Experimental Forest and Range (Starkey) in northeastern Oregon. From 2001 to 2003, 26 stands of true fir and Douglas-fir that suffered high rates of mortality from an outbreak of spruce budworm were selectively thinned (spring or summer) and burned (fall) while 27 similar stands were left untreated to serve as experimental controls. We used location data for elk and mule deer collected during spring (1 April–14 June) and summer (15 June–31 August) of 1999–2006 to compare use of treated and untreated …
Restoring Mixed Conifer Ecosystems To Pre-Fire Suppression Conditions In Crater Lake National Park, Rachel Clark
Restoring Mixed Conifer Ecosystems To Pre-Fire Suppression Conditions In Crater Lake National Park, Rachel Clark
Joint Fire Science Program Briefs (2007-2012)
Mixed-conifer forests dominated by ponderosa pine trees prevail across the Western United States. Once sustained by frequent, low-intensity fires, these ecosystems have changed dramatically as a result of a hundred years of fire suppression resulting in an accumulation of fuels and shade tolerant species. Researchers are finding that reintroducing fire to these systems may be more complicated than once thought. The forests at Crater Lake National Park are a kind of microcosm for the wide-ranging mixed conifer forests across the West. Early efforts to restore fire at Crater Lake showed that older ponderosa pines were at risk of mortality via …

A Comparison Of Presettlement Vegetation And Fire Regimes With Current Patterns In Oak Woodlands And Shrublands Of Sw Oregon, Patricia S. Muir Dr., Paul Hosten Dr.
Joint Fire Science Program Research Project Reports
Fuel reduction efforts on BLM lands in southwestern Oregon are motivated by the need to reduce fire hazard and restore and rehabilitate ecosystems. Successful ecosystem restoration depends, in part, on understanding the target: what ecosystem model is considered natural and healthy for a given area? Oak (Quercus garryana) woodlands and shrublands are two of the most characteristic ecosystems in interior valleys of southwest Oregon, and extensive acreages within these systems are treated annually for fuel reduction. However, these are also two of the least understood ecosystems in the region. We know little about their presettlement attributes, responses to disturbance, or …

Characterizing Moisture Regimes For Assessing Fuel Availability In North Carolina Vegetation Communities, Roberta A. Bartlette, James Reardon, Gary M. Curcio
Joint Fire Science Program Research Project Reports
In the southeastern United States prescription burning, fire danger rating and wildfire suppression strategies are constrained by limited knowledge of the influence of moisture content in live vegetation, organic soils, water table and weather. The interactive influence of these factors on fire behavior is not well studied. The 3+ year long study reported here was conducted to gain direct empirical understanding of seasonal fuel and soil moisture dynamics in shrub-dominated pocosin communities, in coastal Virginia and North Carolina, mixed hardwoods communities containing significant laurel and rhododendron understory fuels in western North Carolina and eastern Tennessee, and longleaf pine communities in …
Fuel Reduction And Restoration Of Pine/Hardwood Ecosystems Severely Impacted By The Recent Southern Pine Beetle (Dendroctonus Frontalis) Epidemic In The Southern Appalachians, James M. Vose, Katherine J. Elliott
Fuel Reduction And Restoration Of Pine/Hardwood Ecosystems Severely Impacted By The Recent Southern Pine Beetle (Dendroctonus Frontalis) Epidemic In The Southern Appalachians, James M. Vose, Katherine J. Elliott
Joint Fire Science Program Research Project Reports
As a result of this most recent SPB epidemic (1999-2003), thousands of hectares of dead pine trees have created wildfire-hazard conditions in the southern Appalachians. One of the challenges for land managers is how to return fire to these ecosystems after (1) nearly a decade of exclusion, and (2) the more recent SPB mortality enhanced fuel loads. Higher fuel loads have the potential to increase fire intensity and severity. At the extremes, fires of high intensity and severity can have a large effect on ecosystem structure and function. The objectives of our research were: (1) to quantify fuel load reduction …

Fire In Southern Appalachians: Fuels, Stand Structure And Oaks, David L. Loftis, Mary A. Arthur, Rex Mann, Jeffrey Lewis
Joint Fire Science Program Research Project Reports
Managers responsible for maintaining the diversity and productivity of Southern Appalachian forests are increasingly turning to prescribed fire as an important management tool in oak dominated forests. The decision to use fire with increasing frequency and spatial extent is based, in part, on an emerging sense of the prehistoric significance of fire in this landscape and its potential to control the proliferation of fire-sensitive competitors in contemporary forests. While it is well documented that fire has been an important ecological force in Southern Appalachian forests for a very long time, there has been little research to demonstrate that prescribed fire …

• We identified annual area burned for 37 National Forests in Washington, Oregon, and California between 1929 and 2004 from annual fire reports. Variation in area burned each year on National Forest lands is strongly related (r2 = 0.87) to total area burned in California. This indicates area burned in National Forests is a good indicator of total area burned in a state. • Four large groups of National Forests were identified that had similar temporal patterns of fire extent. Three of these groups were spatially coherent and included mainly: 1) Washington and northern Oregon; 2) northern California and California …

In recognition of the bilingual context in which conservation occurs in the three countries of the Sangha region — Cameroon, Central African Republic, and Congo — all sessions of the conference were conducted simultaneously in French and English. This publication, which is a complete rendering of the conference papers and discussion sessions, is available in its entirety in both French and English.
Winter Activity Patterns Of American Martens (Martes Americana): Rejection Of The Hypothesis Of Thermal-Cost Minimization, Gary S. Drew, John A. Bissonette
Winter Activity Patterns Of American Martens (Martes Americana): Rejection Of The Hypothesis Of Thermal-Cost Minimization, Gary S. Drew, John A. Bissonette
Green Canyon Environmental Research Area, Logan Utah
Despite their temperate to subarctic geographic range, American martens (Martes americana) possess a thermally inefficient morphology. The lack of morphological adaptations for reducing thermal costs suggests that marten may use behavioral strategies to optimize thermal budgets. During the winters of 1989-1990 and 1990-1991, we radio-collared and monitored the diel activity of 7 martens. A log-linear model suggested that the presence or absence of light was the only factor associated with marten activity patterns (p < 0.001). A regression of the percentage of active fixes on ambient temperature failed to detect an association (b = -4.45, p = 0.084, n = 12). Contents of marten seats suggested that their activity was consistent with the prey-vulnerability hypothesis. While martens must balance multiple life requisites, their activity patterns suggest that they accept increased thermal costs in order to increase foraging efficiency. However, the nocturnal activity of martens during winter was also consistent with the hypothesis that they may be able to limit their own exposure to predation risk. The nocturnal habits of Newfoundland martens in the winter were consistent with the hypothesis of avoidance of predation risk.
Douglas-Fir Beetle, Richard F. Schmitz, Kenneth E. Gibson
Douglas-Fir Beetle, Richard F. Schmitz, Kenneth E. Gibson
The Bark Beetles, Fuels, and Fire Bibliography
The Douglas-fir beetle (Dendroctonus pseudotsuqae Hopk.) infests and kills Douglas-fir throughout most of its range in western United States British Columbia and Mexico. Occasionally western larch trees are infested when growing among Douglas-fir under attack. Attacks in standing larch are always unsuccessful, while those in freshly felled larch are usually successful and brood emergence is equivalent to that in Douglas-fir. Douglas-fir beetles normally kill small groups of trees, but during outbreaks 100 tree groups are not uncommon (fig. 1). Losses can be devastating during periodic outbreaks, such as four that occurred in western Oregon and Washington from 1950 through 1969, …

Hydraulic Lift And Soil Nutrient Heterogeneity, Martyn M. Caldwell, John H. Manwaring
Green Canyon Environmental Research Area, Logan Utah
Water released at night from roots into upper portions of the soil profile in the process of hydraulic lift may contribute to reducing spatial soil nutrient heterogeneity. A manipulative field experiment was conducted in a semiarid shrub stand to determine if circumvention of hydraulic lift, by nighttime illumination of the shrub canopy, would result in greater soil nutrient heterogeneity than if the hydraulic lift process was allowed to operate. Nutrient-enriched patches were superimposed on the existing soil heterogeneity and after 40 days, the patches and interspaces were sampled for ions of different mobility and for root mass. There was no …
Stratospheric Ozone Reduction, Solar Uv-B Radiation And Terrestrial Ecosystems, Martyn M. Caldwell, Stephan D. Flint
Stratospheric Ozone Reduction, Solar Uv-B Radiation And Terrestrial Ecosystems, Martyn M. Caldwell, Stephan D. Flint
Green Canyon Environmental Research Area, Logan Utah
Stratospheric ozone reduction is occurring and will continue to increase in magnitude into the next century. Yet, the consequences for terrestrial ecosystems of the increased solar W-B (280-320 nm) radiation resulting from total column ozone reduction are not understood. Based on studies of higher plant response to UV-B, several possible consequences for ecosystems include decreased primary production, altered plant species composition, and altered secondary chemistry with implications for herbivory, litter decomposition and biogeochemical cycles. However, like the assessment of increased atmospheric CO2, extrapolation from studies with isolated plants to ecosystem function is very tenuous at best. Very few UV-B studies …
