A Tree Ring Based Fire History of the Clover Mountains, Lincoln County, Nevada
Fire is a dominant form of disturbance in the American west, and is a primary management concern because of its threat to natural resources and human development. Research on fire history of the Great Basin is lacking. Here I summarize the results of a fire history study in the Clover Mountains of …

Fire History of an Acidic Barrens Complex: A Methods Assessment of Fire Return Intervals
Fire-scarred trees provide an important source of data and direct evidence for understanding past fires and vegetation dynamics. Although dendrochronological fire scar records provide fine-scale temporal and spatial resolution, limitations exist in the development, analysis, and interpretation of …

A 4700-Year Record of Lake Evolution and Fire History for Laguna Limon, Dominican Republic
Fire is a primary driver of environmental change that can originate from natural or human ignition. Macroscopic charcoal (>125 "m) deposited into lake sediment is a record of a local fire event, whereas microscopic charcoal indicates fire activity on a broad landscape scale. Patterns of charcoal …

Fire Ecology of Northern Andean grasslands: Estimating recent fire history and its impact on páramo plants
… and sustainable management is a high priority. Fires are the most significant human impact in the páramo, yet fire regimes and the response of plant communities to fire are not well understood (Luteyn, 1992; Laegaard 1992; Ramsay and Oxley, 1996; Ramsay, 2001; Horn & Kappelle, 2009). A …

Holocene Fire History Reconstruction of a Mid-Evaluation Mixed-Conifer Forest in the Eastern Cascades, Washington
Fire histories of mid-elevation mixed-conifer forests (MEMC) are uncommon, particularly in the eastern Cascades of Washington. As a result, fire regimes and the effects of 20th century fire suppression in these forests are not well understood. In the summer of 2014 a 7.80 meter-long sediment core …

Burning for birds : the response of bird communities to recent fire history in the Serengeti ecosystem
Fire is a ubiquitous ecosystem process with important implications for savanna ecology and conservation. In this study we aimed to explore the short-term and long-term effects of recent fire history on bird communities in the greater Serengeti savanna ecosystem in Tanzania. The study investigated …

A Regional Synthesis of Post-Glacial Fire History in the Eastern Cascades, Washington, Using Macroscopic Charcoal Analysis
<p>The recent rise in severe wildfires in the Pacific Northwest (PNW) has created a heightened sense of urgency and reignited public interest in wildfire risk. In order to put this rise into a broader spatial and temporal context, a more in-depth look at fire histories from frequently burned areas …

Postglacial Reconstruction of Fire History from a Small Lake in Southwest Yukon using Sedimentary Charcoal and Pollen
… an increase in the frequency and severity of wildfire. Recent wildfire seasons in northern Canada generally support these studies, with some of the worst fire seasons on record occurring during the past few years. While we can readily track the spatial and temporal distribution of these events …

Post-Glacial Fire History of Horsetail Fen and Human-Environment Interactions in the Teanaway Area of the Eastern Cascades, Washington
… unclear how past relationships between people, fire, and climate interacted on the landscape. The purpose of this research was to reconstruct the post-glacial fire history of a wetland known as Horsetail Fen, located in the Teanaway area of the eastern Cascades of Washington State. The goal was …

Forest structure in unharvested old-growth: understanding the influence of soils on variability of long-term tree dynamics and fire history
… North American forests adapted to frequent fires have been fundamentally altered and fragmented as a result of fire exclusion, the transportation infrastructure, development patterns, and other landscape level changes. In order to enhance the resiliency, diversity, and productivity of forest …

Laser-based method for black carbon determination in lake sediment cores and black carbon deposition in Greenland since 300 CE
… in ice cores, can be used to reconstruct forest fire history over past millennia. Thus, quantifying BC's role in the climate system is important for understanding both fire history and Earth's radiative budget. This study presents a new method for measuring BC in lake sediment cores using a …

Comparison of Charcoal and Tree-Ring Records of Recent Fires in The Northern Rocky Mountains, Kalispell, MT, USA
… In this study we created a dendrochronological fire history using fire-scarred trees in the watershed of Foy Lake in the Flathead Valley, MT, to determine the synchronicity between two fire proxies: the watershed’s tree fire scar chronology and the dated charcoal in the sediment lake strata. I …

The macro-charcoal signature in Bwabwata National park, north-east, Namibia: Calibrating surface macro-charcoal with environmental variables
Fire is a major driver of vegetation patterns in the savanna biome of southern Africa and is hypothesized to allow for the tree-grass co-existence. However, to better understand the drivers of the savanna vegetation structure, more research is required. Furthermore, fire management can benefit …

A stable isotope and macro-charcoal sediment record spanning the Pleistocene-Holocene transition from Maple Pond in the southern Shenandoah Valley, Virginia, USA
… years of continuous sediment accumulation, fire history, and environmental variability from the Late Pleistocene to the present. Stable carbon isotope ratios (δ13C: -29‰ to -27‰) and atomic C:N ratios (11-36) indicate terrestrial C₃ vegetation as the primary source of organic matter during …

Effects of Prescribed Fire Regimes on White-tailed Deer (Odocoileus virginianus) Browse, Forage, and Nutrient Availability in the Pineywoods Ecoregion of Texas
<p>Fire is a management tool for white-tailed deer (<em>Odocoileus virginianus</em>) habitat, influencing browse availability, herbaceous production, and nutrient content. In 2020 and 2021, this study utilized 46 plots across East Texas to assess these habitat components. A stem count index survey …

Do wetland characteristics, specifically plant communities, surface water, and soils play a significant role in whooping crane (<i>grus americana</i>) site selection?
… twenty non-nesting wetland sites. Due to past fire management throughout the refuge, the effects of fire history were also investigated by comparing burned (n=17) and un-burned (n=22) areas.</p> <p>A multi-dimensional scaling analysis did not detect significant differences in plant community …

Late Quaternary fire histories in the eastern Mediterranean region from lake sedimentary micro-charcoals
The Eastern Mediterranean has a long history of human occupation, which spans the transition from hunter-gatherers to the establishment of early agro-pastoralist communities, coinciding with the Last Glacial: Interglacial transition. Over the same timeframe a delay in postglacial woodland …
