Rather, the intent is to maintain as much biodiversity as possible by restoring disturbance processes and patterns in ways that allow humans to meet current and future needs from the landscape. Finally, we propose some critical considerations for future conservation efforts of North American grasslands and include some examples of perspectives that have been applied. cow-calf, stocker steers) and the sex ratio is often highly skewed depending on the objective. For one, improved monitoring of prairies and conversion would enable the focusing of policy and protection efforts on those locations of highest need. Similarly, climate projections, as well as land use changes, suggest that these landscapes will become more different from their pre-historical conditions over the next century. Since Glacial Maximum, vegetation and climate have been dynamic, suggesting that contemporary ecosystems are not good indicators of past conditions [42,43]. However, in the case of fire, it largely remains an objective for the future. For the first time, consumers are now able to contribute to grassland conservation efforts through their fork by selectively purchasing beef from Audubon-certified farms and ranches, like Ranney Ranch. Lastly, we discuss a perspective that is less focused on the question of which herbivore to include, but more focused on restoring the pattern and processes of herbivory on grassland landscapes [12,13]. A matrix illustrating the complex conditions that can exist with all contributing to ecosystem functions and biodiversity on grasslands.Download figureOpen in new tabDownload powerPoint. Native grassland and pollinator habitat conservation is vital to agriculture and to Nebraska wildlife. In some cases in the North American Great Plains, prairie dogs may be keystone species that influence large herbivore distribution, plant species composition and biodiversity. These models have similarities and differences and none are complete on their own, but we have chosen them for comparison to describe the complexities and challenges of grassland conservation on contemporary landscapes. While all conservation perspectives partly address the three domains, they all fall short in key areas. Further, lack of clear objectives and outcomes from the conservation community make the limited evidence of differences between these herbivores all but irrelevant for predictive purposes. Continue education efforts, particularly among farmers, on how to protect the soil and prevent soil … In order for the WGFD to successfully implement large-scale grassland conservation efforts, it September 2006 2 Wyoming Game and Fish Department. landscape fragmentation, woody plant encroachment, alteration of fire regimes, cultural demand on natural resources). While these ideas are engaging to many and stimulate excitement, they are usually based on a romantic objective of restoring something long lost and probably impossible to restore. Early Clovis hunters are most often associated with the extirpation of 35 genera of large mammals in North America at approximately 11 000 years ago [15,16]. Shifts from C3 to C4 grass dominance would have a substantial influence of altering critical features associated with forage quality and quantity. We own and manage 78 acres in the heart of the IBA at the site of our our Alfred Z. Solomon Grassland … One of the focuses of climate science has been to understand the nature of the balance needed to promote a healthy temperate biome. This can mean that even fire-adapted plants (such as some pines and palms) are killed. One contribution of 16 to a theme issue ‘Trophic rewilding: consequences for ecosystems under global change’. Specifically, we (1) selected stream and grassland species of common conservation interest to partnering states, (2) modeled and mapped regional distributions of these species, and (3) used predicted species occurrences to identify regional conservat ion focal areas. Email: firstname.lastname@example.org. bison) then this decision is simplified considerably. They originally claimed that their goals and ideas of restoring the original anthropogenic extirpations were ‘justified on ecological, evolutionary, economic, aesthetic and ethical grounds’ . After animals remove the vegetation by overgrazing, grasslands are susceptible to erosion by wind and water, which may convert the land into desert — thus making it generally unable to sustain vegetation. More recently, agricultural policy has promoted the conversion of marginal cropland back to grassland, but these landscapes remain highly fragmented  and the vast majority of many of these grasslands, such as the Great Plains, remain privately owned and managed for agriculture and energy development. For example, cattle herds are typically associated with ranches that are managed for optimum commodity production. A new look at an old debate, Wildlife encounters by Lewis and Clark: a spatial analysis of interactions between native Americans and wildlife, Impact of an agri-environmental scheme on landscape patterns, Rotational grazing on rangelands: reconciliation of perception and experimental evidence, Application of the fire-grazing interaction to restore a shifting mosaic on tallgrass prairie, A hierarchical perspective to woody plant encroachment for conservation of prairie chickens, Foraging ecology of bison and cattle on a mixed prairie: implications for natural area management, Vegetation trends in tallgrass prairie from bison and cattle grazing, Ungulate preference for burned patches reveals strength of fire-grazing interaction. The focus is to conserve populations of migratory birds by protecting the unique, highly diverse, and endangered ecosystem known as the Prairie Pothole Region. Figure 3. Protecting grassland ecosystems conserves biodiversity, and results in cleaner streams, less fertilizer runoff, increased numbers of pollinators for plants, and high carbon sequestration in soils. European settlement fragmented large landscapes, introduced cultivation and domestic livestock and concomitantly reduced fires. This approach to conservation may loosely recognize that landscapes are spatially and temporally dynamic and largely dependent upon people, but they generally fall short of incorporating these concepts into any semblance of a workable plan . Consequently, it is a challenge for conservation to achieve the vision necessary to restore and/or maintain grassland ecosystems, but also remain practical with modern society and the requirements of agricultural and energy production.
