JFSP Research Project Reports
A major problem in post-fire restoration of semi-arid shrublands dominated by annual bromes is the presence of carryover seed banks that cannot be controlled using conventional methods. These seeds can provide significant competition for seeded species in the years following treatment. We investigated the feasibility of using a naturally occurring seed pathogen, the ascomycete Pyrenophora semeniperda, as a biocontrol organism for eliminating this carryover seed bank. We carried out the necessary technology development to create and apply field inoculum to cheatgrass- or red brome-infested areas (both burned and unburned) at six sites located in three states across two years of …

Fire is a significant and essential disturbance in ponderosa pine ecosystems but the management and the re-introduction of fire across the landscape is a difficult task for land managers. In this study we worked with land managers, stakeholders and researchers to examine the effects of a large wildfire on the Kaibab Plateau in northern Arizona. We analyzed litter and duff depth, downed woody debris and understory vegetation responses to low and high burn severity and assessed the response of the understory vegetation to seeding with Lolium perenne ssp. multiflorum in high severity burn areas. To assist land managers in future …

The use and cost of post-fire emergency stabilization treatments continues to grow. To help maximize the impact of these treatments, many assessment teams use the Erosion Risk Management Tool (ERMiT) erosion model to predict postfire erosion and mitigation effects. However, despite several completed JFSP projects, the long-term effects of these treatments remain unknown, and the ERMiT model has not been validated. Long-term post-fire erosion and runoff data on a variety of mulches and erosion barriers were collected using 12 existing sites throughout the Western U.S. The agricultural straw and wood strand mulch treatments were very effective at reducing erosion and …

A web-programming project was undertaken to allow users of the online Hand-piled Fuels Biomass Calculator to also estimate the volume, biomass and potential emissions of mechanically piled fuels. Machine pile calculations encoded in the decision support software CONSUME 3.0 were added to the online Calculator to achieve this objective. In addition, the ability to batch process piled fuels data was added to the online Calculator to ease data input for large analysis projects. A stand-alone version of the Calculator was developed for users without access to the Internet. As it is executed within a standard web browser (e.g., Microsoft Internet …
Evaluating The Effects Of Pinyon Thinning Treatments At A Wildland Urban Interface, J. R. Matchett, Matthew L. Brooks, Anne Halford, Dale Johnson, Helen Smith
Evaluating The Effects Of Pinyon Thinning Treatments At A Wildland Urban Interface, J. R. Matchett, Matthew L. Brooks, Anne Halford, Dale Johnson, Helen Smith
JFSP Research Project Reports
This study evaluated the short-term effects of thinning methods for pinyon pine woodlands at two sites in the southwestern Great Basin. Both cut/pile/burn and mastication treatments were equally effective at reducing the target fuels which were mature, live pinyon trees. Application costs though differed substantially, with the cut/pile/burn technique being less expensive. Thinning treatments increased the abundance of herbaceous vegetation, although in some cases the strength of the increase was constrained by the level of pre-treatment tree dominance. Increases in perennial grass cover and density in response to thinning were usually greatest at lower levels of pre-treatment pinyon dominance, whereas …

Exploring The Traditional Use Of Fire In The Coastal Mountains Of Central California, Brent E. Johnson, Rand R. Everett, Kent G. Lightfoot, Charles J. Stiplen
JFSP Research Project Reports
This study brought together a team of ecologists, archaeologists, environmental historians, indigenous peoples, and land managers within a research framework combining an ethnographic investigation of traditional practices with cutting-edge paleoecological techniques to answer questions about Indian utilization of fire as an ecological and cultural landscape management tool in Central Coastal California. The study was designed around four key elements: (1) examining fire regimes for research sites using a combination of fire scar dendrochronology, phytoliths, archaeology, historical information, and traditional ecological knowledge; (2) attempting to formalize a methodology for using phytoliths to estimate the fire return interval and intensity in grassland …

Fire Regimes Of The Southern Appalachian Mountains: Temporal And Spatial Variability Over Multiple Scales And Implications For Ecosystem Management, Charles W. Lafon, Henri D. Grissino-Mayer, Sally P. Horn, Robert N. Klein
JFSP Research Project Reports
Information about historic fire regimes and the departure of current fire regimes from historic conditions is essential for guiding and justifying management actions, such as prescribed burning programs for ecosystem process restoration and fuel reduction. Such information is noticeably lacking for the southern Appalachian Mountains, where human populations are encroaching onto wildland areas, and where decades of fire exclusion have contributed to the decline of fire-associated communities and also to altered fuel loads. We address this knowledge gap via a multi-scale investigation of the variability in fire regimes over time and space using tree-ring reconstructions of fire history and stand …

We studied the nesting ecology and movement patterns of Eurasian black vultures (Aegypius monachus) nesting in and near Ikh Nart Nature Reserve, Dornogobi Aimag, Mongolia. From 2003 till 2009, we monitored nesting pairs from incubation to fledging and compared nesting success for pairs nesting on rocks and trees. We captured chicks just prior to fledging to apply leg bands and wing tags. We also captured adults in June and attached solar-powered global positioning system (GPS)/satellite telemetry units, leg bands, and wing tags. We collected resighting data on marked birds opportunistically and telemetry data on tagged birds. We monitored …

First paragraph:
Seit der ersten Mongolisch-Deutschen Biologischen Expedition im Jahre 1962 hat die Erforschung der Avifauna große Fortschritte gemacht, wobei im Zoologischen Institut der Martin Luther Universität Halle-Wittenberg, der Mongolischen Akademie der Wissenschaften und dem Biologischen Institut der Nationaluniversität der Mongolei in Ulaanbaatar umfangreiche Balgund Skelettsammlungen angelegt wurden. Nicht wenige Vogelfunde lagen aber in Form von Nahrungsresten der Greifvögel, Eulen und des Haarraubwildes vor und waren damit nur schwer anzusprechen. So gingen die aufgesammelten Rupfungen und Säugetierrisse zumeist an den Autor, in der Hoffnung, dass sie bestimmt werden können.

Water is a key resource for most large bodied mammals in the world’s arid areas. With the growing human population, access to water for wildlife often becomes compromised. Equids are typical inhabitants of semi-arid to arid rangelands and need regular access to fresh water. However, their water needs are difficult to study under free-ranging conditions. In this study we investigated Asiatic wild ass (Equus hemionus) use of permanent water points in the Great Gobi B Strictly Protected Area (SPA) in south-western Mongolia. We combined observational data from one specific water point with high frequency GPS location data from …

Group size is an important variable describing behavioral ecology of animals. A variety of factors such as habitat characteristics, life history, spatio-temporal resource dynamics, population density, predation risk, competition with kin, and social learning often determine group size in large mammals. We studied temporal dynamics of group size in Siberian ibex (Capra sibirica) in a protected area in Mongolia. We measured monthly and yearly variations in typical group size and used the sexual segregation and aggregation statistic to assess sexual segregation. Ibex formed the largest groups in November and smallest groups in July. However, group sizes did not …

Behavioral observations of free ranging animals can provide important insight into many aspects of their biology but are not without problems. The recent development of GPS technology allows to remotely collect high precision location data at fixed intervals. We tested whether it is possible to classify the behavior of a Przewalski’s horse in the Mongolian Gobi into Resting, Grazing and Moving based on GPS locations collected at 15 minute intervals by comparing GPS data with direct observations. Although behavioral categories lasting for 15 minutes could by fairly reliably separated based on the distances covered between successive fixes, almost half the …

The toad headed agama (Phrynocephalus versicolor) ranges across the arid steppe regions of southern and western Mongolia and represents one of the most common reptiles in the country. However, few details of the species’ population characteristics exist, which may be important for evaluating population trends and assessing its conservation status. We estimated toad headed agama density in Ikh Nart Nature Reserve, Mongolia based on surveys conducted in the summers (June-September) of 2005, 2006, 2008, and 2009. We conducted surveys in three steppe habitats including tall grassland (n = 7), shrub-steppe (n = 7), and semi-shrub steppe …

Bats of the steppe habitat require particular attention in Mongolia because of increasingly frequent droughts and the looming specter of global warming which could have a devastating impact on their population. Especially the bats in arid steppe region lack of water resources. All bat species we trapped in Erdenesant, Tov aimag, were using hand dug wells as water source indicating the significance of water availability. Many wells have been dried out or polluted in Mongolia in recent years due to warming effect of climate change and artisanal mining activities, but the extent of their impacts on bat populations have to …

Geomorphological, geochemical, sedimentological and palynological results are presented against the background of palaeoclimatic changes during the past 15,000 years, yielding a chrono-, bio- and morphostratigraphical model of landscape evolution in the region of northern Central Asia. Holocene and Late-Glacial climatic fluctuations there are shown to correlate well with conditions in central Europe. Particular attention is given to the importance of the palaeoclimatic interpretation of lake Basin sediments when reconstructing the palaeoenvironment.

During 1988-2004 Russian and German biologists carried out a research of biodiversity of the mountain taiga within the territory of State Nature Reserve “Azas” (Republic of Tyva/Russia). Along with executing the main task – studying and development of an aboriginal population of Tuvinian beavers Castor fiber tuvinicus – materials on the fauna of small mammals of the Todzha kettle were collected. On the basis of samples (about 550 collected micromammals) information on the occurrence, reproduction and morphometric characteristics of four species of Insectivora, six species of Chiroptera and eleven species of small Rodentia inhabiting the territory of the reserve “Azas” …
