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
JFSP 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 …

The Digital Photo Series (DPS) is a web-based application that provides access to the Natural Fuels Photo Series database and photographs. The DPS works through a user’s internet browser, but has also been designed to work as a stand-alone application when the computer is disconnected from the internet. A user-friendly interface allows users to browse, query, and download photo series data and high-quality photographs. The Digital Photo Series is intended to complement, not replace, the printed photo series volumes.

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.
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
JFSP 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 …

This final report summarizes key findings relative to the five major objectives listed in our proposal, along with the crosswalk of accomplished and future deliverables. Additional details concerning objectives, methods, results, and recommendations are presented in Attachment A. Each of our major objectives is listed below with a brief summary of findings to date. Because we only recently finished the final session of data collection, all findings are preliminary and may change as more comprehensive statistical analyses are completed. 1. Evaluate the effects of fire on southern California rodent, large mammal, and bat diversity and study patterns of post fire …

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
JFSP 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 …

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 …

Chlorophacinone Baiting For Belding’S Ground Squirrels, Craig A. Ramey, George H. Matschke, Richard M. Engeman

The efficacy of using 0.01% chlorophacinone on steam-rolled oat (SRO) groats applied in CA alfalfa by spot-baiting/hand baiting around burrow entrances (~11.5 g) to control free-ranging Belding's ground squirrels (Spermophilus beldingi) were compared in 6 randomly assigned square treatment units (TUs). Four TUs were given the rodenticide and 2 treated with placebo bait. Each TU was a 0.4 ha square surrounded by a similarly treated 5.5 ha square buffer zone. Baits were applied on May 13 and re-applied, on May 20 and May 22, after 7 days of un-forecasted cool wet weather greatly reduced their above ground activity. Pesticide (EPA …
