This book was released on 2006 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic land use alterations such as livestock grazing and fire suppression have greatly altered sagebrush grasslands of the Great Basin, facilitating invasion of exotic annuals, increases in woody species, and losses of native species. Much of the current research surrounding wildland and prescribed fire in sagebrush dominated ecosystems has focused on a persistent belief that fire in sagebrush systems results in a loss of native flora and a trend toward dominance by exotic annuals. Fire was historically the dominant disturbance throughout the sagebrush steppe and the plant species that comprised these communities possess a variety of adaptations facilitating survival to the fire regime. In order to restore ecosystems, land managers will need to reintroduce natural ecosystem processes, including natural disturbance processes. To describe the response of these plant communities to fire, I examined the plant community response, seedbank response, and reproductive and density responses of three native bunchgrasses (Pseudoroegneria spicata, Achnatherum therberianum, and Elymus elymoides) as well as one native forb (Calochortus macrocarpus) following spring and fall prescribed fires at Lava Beds National Monument. Fires were applied to three Artemisia tridentata ssp. vaseyana (Mountain Big Sagebrush) plant communities with different land use and fire histories. These communities were different in composition ranging from a dominance of exotic annuals to dominance by native grasses, shrubs, and trees. Little is known about how prescribed fire affects the soil seed bank in sagebrush-dominated ecosystems. To address this, we quantified the emergence of Bromus tectorum (cheatgrass) seedlings as well as emergence of seedlings of functional groups (native forbs, bunchgrasses, and shrubs) in a seedbank germination study. At the invasive dominated site (Gillems Camp), we found 91% fewer B. tectorum seedlings germinated in spring burned sites than in controls immediately following spring prescribed burns. However, soils collected one-year following fire had 40% more B. tectorum germinants (8017 germinants/m [superscript 2]) than unburned controls (5132 germinants/m [superscript 2]). Following fall burns at this site there was a similar response, with a 56% immediate reduction in B. tectorum (as compared to unburned control) and a 59% increase in B. tectorum and 58% increase in exotic forb germinants one year following fires. There was an increase in native forb germination following spring burns (94%) and fall burns (45%) at a site dominated by native plants (Fleener Chimneys). Native bunchgrass seed germination declined following spring fire in sites dominated by sagebrush and native understory vegetation (79%), and in sites where Juniperus occidentalis (western juniper) and other woody species dominated (Merrill Caves) (71%). In invasive-dominated sites (Gillems Camp), there was a decrease in B. tectorum cover following both spring (81% decrease) and fall fires (82% decrease), and little native vegetation composition change. Shrub cover, made up predominantly of Chrysothamnus nauseosus, decreased following spring (95% decrease) and fall (93% decrease) fires. At the sagebrush, native understory site (Fleener Chimneys), there was a reduction in native bunchgrass cover (64% decrease), and an increase in native forbs (168% increase) following spring burns, with no changes following fall fires. At the juniper- woody dominated site (Merrill Caves), fire treatments resulted in a decrease in woody plant cover, with no immediate postfire differences seen in the herbaceous plant community. Density of bunchgrass species (Pseudoroegneria spicata, Achnatherum therberianum, Elymus elymoides) did not change following either spring or fall prescribed fire treatments. Fire enhanced flowering was not seen in C. macrocarpus following spring or fall burns at the native or juniper dominated sites. There was increased reproductive effort in native bunchgrass species following fires in all communities studied. Following spring fires at invasive dominated sites, there was a 245% increase in reproductive culms of P. spicata. Following fall fires in native dominated sites, we saw a 974% increase in reproductive culms of P. spicata and a 184% increase in reproductive culms of A. therberianum. Following fall fires at juniper-dominated sites, we saw in an increase in reproductive culms of P. spicata (678% increase), A. thurberianum (356% increase), and Elymus elymoides (209% increase). These results suggest that implementing prescribed fire in order to restore the natural disturbance regime in these fire-adapted ecosystems is beneficial to restoration and preservation of the native biota.

Available in PDF, EPUB and Kindle. Book excerpt: Grasslands can support high levels of biodiversity and provide numerous ecosystem services, but they have been widely degraded, often via loss of natural disturbance regimes. North American grasslands were once created and maintained by fire. In some cases, fire has been more important than climate in determining the distribution and extent of grasslands. Conservation of the biodiversity harbored by grasslands relies, in part, on ecological restoration of these habitats and the fire regimes that historically maintained them. In this dissertation, I examined the effects of prescribed fire on grassland plant species and plant communities of the southern Great Plains in the short-term (up to two years after fire) and longer-term (twelve years after fire). Cool-season prescribed burns (those conducted in January – March) were not sufficient to shift overall plant community composition (e.g., increase richness of native plant species or reduce cover of the invasive grass Bothriochloa ischaemum) in 10 sites distributed from central Texas to southern Oklahoma (Chapter 2). However, these fires did have measurable effects on eight individual forb species in the same sites (Chapter 3). In general, the eight forb species studied individually responded to the winter fire individualistically, but all three annual species increased their floral displays (flowers/m2) in the burned plots in the short term. Forb species that increased their floral display in burned areas did so via increased plant biomass (grams of dry aboveground biomass) or plant density (plants/m2). We found little evidence that these forb species shifted their resource allocation towards reproduction. In a separate study (Chapter 4), a prescribed fire conducted in July was sufficient to shift plant community composition in the short term, mostly by reducing the cover of the invasive grass B. ischaemum and increasing native species richness; the latter effect was likely the result of reducing B. ischaemum. In the same study, only the increases in native grass cover and richness were still detectable twelve years after the fire. Perhaps due to two additional cool-season fires across the entire site, B. ischaemum cover remained low twelve years after the fire in burned plots but unexpectedly had also decreased in unburned plots. The results from all three chapters supported our expectation that summer fires would be more effective than cool-season fires in changing the plant community composition, including controlling the invasive grass B. ischaemum. Interestingly, forb species were highly individualistic, from differences in their abundances among sites in the multi-site study (Chapter 3) to differences in their responses to fire (Chapter 4). These findings support conducting prescribed fires in summer months to control invasive grasses and to increase native plant species richness, and consequently conserve the biodiversity supported by grasslands in this region

Book Synopsis Rangeland Systems by : David D. Briske
Download or read book Rangeland Systems written by David D. Briske and published by Springer. This book was released on 2017-04-12 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.
Book Synopsis Fire Ecology and Prescribed Burning in the Great Plains by : Henry A. Wright
Download or read book Fire Ecology and Prescribed Burning in the Great Plains written by Henry A. Wright and published by . This book was released on 1980 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historical evidence indicates that fires were prevalent in grasslands. In the past, big prairie fires usually occurred during drought years that followed 1 to 3 years of above-average precipitation, which provided abundant and continuous fuel. Fire frequency probably varied from 5 to 10 years in level-to-rolling topography and from 15 to 30 years in the rougher, dissected topography containing rough breaks and rivers. This paper contains basic ecological information, vegetative descriptions, and fire effects data for the shortgrass, mixed grass, and tallgrass prairies in the southern, central, and northern Great Plains. In the appendix, fire effects data have been tabulated for each species for quick reference. Prescription guides are provided for all major vegetation types where prescribed burning data have been collected. In the shortgrass prairie, grasses do not benefit from prescribed burning, but fire can be used to clean up uprooted brush, kill small juniper, and kill cactus. Prescribed fire has a wider variety of uses in the mixed and tallgrass prairies, particularly if the burns are conducted following winters with above-average precipitation. Major benefits of prescibed burning are to control undesirable shrubs and trees, burn dead debris, increase herbage yields, increase utilization of coarse grasses, increase availability of forage, improve wildlife habitat, and to control exotic, cool-season grasses. Often, several objectives can be achieved simultaneously. Prescribed fire frequency should not be more often than 5 to 8 years in a 20-inch (51-cm) precipitation zone but can be as often as 1 to 3 years in a 35- to 40- inch (89- to 102-cm) precipitation zone. Good soil moisture in the upper 1 ft (0.3 m) of soil is especially important before conducting a prescribed burn if the goal is to increase yield and palatability of forage. If control of shrubs is the primary consideration, such as in juniper country, burning during drought years may have the best long-term effect. To use prescribed fire is not as dangerous as most people think, providing it is done by experienced personnel. We recommed a minimum of 2 years of prescribed burning experience under a range of weather conditions for individuals having major supervisory responsibilities. Moreover, we recommend that supervisors be trained in planning and conducting burns and in evaluating the weather. To achieve a desired effect and for safety, one must have the skill to recognize, and the patience to wait for favorable weather.
