Another tool in the toolbox? Using fire and grazing to promote bird diversity in highly fragmented landscapes
(Ecological Society of America, 2011-03-08)The grasslands of central North America have experienced drastic reductions in extent, removal of historic disturbance patterns, and homogenization of remaining fragments. This has resulted in steep declines for a broad ... -
Black-tailed Prairie Dog and Large Ungulate Response to Fire on Mixed-grass Prairie
(Oklahoma State University, 2010-12-01)Restoring historic fire-grazing regimes and the declining keystone species the black-tailed prairie dog (Cynomys ludovicianus) are two management priorities in North America's grasslands. My study sought to investigate the ... -
Effects of Fire and Grazing Driven Heterogeneity on N Cycling in Tallgrass Prarie
(Oklahoma State University, 2005-07-01)The purpose of this study was to evaluate the combined interactive effect of fire and grazing on N availability in tallgrass prairie. To address this, data from recently burned, one year since fire, and two years since ... -
Effects of prescribed fire and forest thinning on white-tailed deer forage productivity and quality in a southern oak-pine forest-savanna continuum
(2021-07)White-tailed deer (Odocoileus virginiana) represent an important economic component in the management of forest lands in the USA with over 16 billion dollars of expenditures annually related to deer hunting. Climate change ... -
Effects of season of burn on native forage quality: Implications for cattle and white-tailed deer management
(2021-12)Previous research has examined the benefits of fire and its ability to alter the nutrient quality of forages. Fire increases forage quality, but is largely based upon composite forage samples or on fire removing older, ... -
Empirical Comparison of Three Existing Methods for Simulating Embers in Computer-generated Fire
(Oklahoma State University, 2006-12-01)This study compares computer-generated embers using three existing methods. While there exists research related to fire propagation, flame rendering, and smoke generation, there is nothing that discusses embers. This study ... -
Estimating live fuel moisture content in Oklahoma plants
(2023-05)Live fuel moisture content (LFM) is an important variable in fire danger rating systems. LFM collection is time and resource intensive and plant water relations vary within and between species. Consequently, the best ... -
Fire department fitness and wellness program implementation
(2019-12)Health promotion programs are becoming increasingly popular throughout the private sector. The return on investment averages between $3 - $6 for every dollar spent on program costs. Despite this, implementation has lagged ... -
Fire, Browsing, and Deer Density in the Mixed-Grass Prairie
(Oklahoma State University, 2010-05-01)White-tailed deer are keystone herbivores that have been shown to reduce reproductive success, abundance, diversity, distribution, and survival of plants in the tallgrass prairie. I assessed concerns that deer browsing ... -
Forest floor depth mediates understory vigor in xeric Pinus palustris ecosystems
(Ecological Society of America, 2007)Longleaf pine (Pinus palustris) woodlands and savannas are among the most frequently burned ecosystems in the world with fire return intervals of 1-10 years. This fire regime has maintained high levels of biodiversity in ... -
Implications of pyric-herbivory on central North American grassland ecology, management and production
(2014-07)The interaction of fire and grazing is an ecological process regulating fire-dependent ecosystems. Prior to European settlement, grasslands were regulated by fires and focal grazing by herbivores (pyric-herbivory), a ... -
Interactive effects of grazing and burning on wind- and water-driven sediment fluxes: Rangeland management implications
(Ecological Society of America, 2011)Rangelands are globally extensive, provide fundamental ecosystem services, and are tightly coupled human-ecological systems. Rangeland sustainability depends largely on the implementation and utilization of various grazing ... -
Large scale avian conservation issues in the Great Plains of North America
(2020-12)Globally many bird populations are declining at a rapid pace due to direct and indirect anthropogenic disturbances. Bird collisions with buildings are one major source of direct mortality. Chapter 1 examined species- and ... -
Nesting and feeding ecology of grassland birds in mixed-grass prairie managed with patch-burn techniques
(2009-07)Scope and Method of Study: In 2006-2008, we applied patch-burn management techniques to a sandsage (Artemisia filifolia) mixed-grass prairie in western Oklahoma and compared the responses to traditionally managed (i.e., ... -
Restored Heterogeneity as a Conservation Strategy for Grassland Birds
(Oklahoma State University, 2014-05-01)Grasslands are inherently dynamic in space and time evolving with frequent disturbance from fire and herbivores. Throughout much of the world, grasslands have been converted and fragmented and many remaining grasslands ... -
Spatial heterogeneity increases diversity and stability in grassland bird communities
(Ecological Society of America, 2015)Grasslands are inherently dynamic in space and time, evolving with frequent disturbance from fire and herbivores. As a consequence of human actions, many remaining grasslands have become homogenous, which has led to reduced ... -
Vegetation Pattern and Response in the Context of Heterogeneous Pasture Management in Southeastern Nebraska
(Oklahoma State University, 2014-05-01)Prior to European settlement, the interaction of fire and grazing was a dominant disturbance and driver of vegetation structure and diversity in the Great Plains. Periodic wildfires and anthropogenic fires created burned ... -
Vegetation response to fire and domestic and native ungulate herbivory in a Wyoming big sagebrush ecosystem
(Oklahoma State University, 2011-12-01)Coupling of fire and grazing as a landscape management tool is a global phenomenon in many diverse landscapes. While grazing exclosure studies examining the effects of livestock on rangelands have provided insight into the ...
