We are implementing the BCA model and will be evaluating and assessing the project until at least 2012. The Grasslands Programme team’s goal is to get all 33 pilot sites declared formally either as ‘nature reserves’ or as ‘protected environments’ under the Protected Areas Act. )Download figureOpen in new tabDownload powerPoint, Figure 4. The important attention to conservation of biodiversity, pattern and processes of ecosystems, and rewilding landscapes did not appear until recent decades. Identifying the most appropriate framework for restoring grasslands is dependent on the objectives of restoration, which is inherently determined by human priorities. Human culture in the North American Great Plains has been variable in space and time but generally transitioned from mostly hunter–gatherers to European settlers who were largely focused on subsistence agriculture. Aso Grassland Conservation Center. grasslands provide habitat for pollinators, small mammals, grassland birds and raptors, like the American kestrel. Research in the Great Plains indicates that some segments of the public have a strong aversion to fundamental aspects of biodiversity, such as heterogeneity and diversity of plants [58]. 26-43). After animals remove the vegetation by overgrazing, grasslands are susceptible to … Rotational grazing requires that farmers and ranchers allow their herd animals to graze an area for only a short time and then move (or rotate) them into a different area. Plant invasions or fire policy: which has altered fire behavior more in tallgrass prairie? Simplified conceptual model for North American grasslands indicating the major changes to socio-ecological structure of grassland ecosystems at different times. The American bison became a dominant large herbivore because of a complex interaction with fire (pyric herbivory), humans, predators, other herbivores and the regionally variable climate (figure 3) [12,19]. 2. Programs such as The Temperate Grasslands Conservation Initiative has launched global initiatives and action plans designed to raise awareness for protecting grasslands and to begin conservation efforts in North and South America, Russia, Mongolia, and China. Conservation of remaining landscapes is critical to global biodiversity and will be dependent on multiple models that range from the attempt to restore wilderness to conservation-based management on privately owned landscapes that are agriculturally based. Hence, the Grasslands Programme team is concentrating its efforts on those sites that still have some biodiversity intact, where long-term conservation management can have the biggest impact. Conservation of North American grasslands, including restoring natural disturbance regimes and rewilding landscapes with mega-herbivores or their surrogates, has been a popular topic in ecology [1,2]. Conservation groups, agencies and private land-owners have biases towards native or domestic herbivores despite the fact that studies have demonstrated that similar responses in biodiversity can be achieved by cattle and bison as long as both species are allowed to interact with heterogeneous fire patterns [12,33]. in a Changing Landscape. 2002) and conservation efforts have been directed to maintaining existing areas of these habitats. Despite APR's success, bison conservation and in some cases rewilding have not always acknowledged the complexity of rewilding landscapes and the types of management that may be required to achieve conservation objectives. © 2018 The … The conservation area is an easement program that will be part of a landscape-scale, strategic habitat conservation effort. Municipalities are working to replant grass and revitalize soil where historical growth has caused harm. shifting populations and food production) of such a model. Some conservation approaches have focused on combining components from several of these perspectives. They originally claimed that their goals and ideas of restoring the original anthropogenic extirpations were ‘justified on ecological, evolutionary, economic, aesthetic and ethical grounds’ [9]. Published by the Royal Society. They have restored free-roaming bison and random anthropogenic fires on a large landscape, but are also encouraging research and outreach on developing conservation approaches for surrounding ranchers to promote a similar heterogeneous landscape with domestic livestock [12]. GBT’s Conservation Achievements. The paper also proposes a unified, community-based vision for grassland conservation, which could help coordinate efforts across sectors. There are several conservation efforts underway today: 1. Efforts afoot to save South’s disappearing grasslands Across much of the South, at least 90 percent of native grasslands have been lost, according to the Southeastern Grasslands Initiative. Private lands offer a potential source of hope for grassland and aridland birds, as 84% of grasslands and 44% of aridlands are held in private ownership; therefore, private land conservation efforts could have substantial population‐level impacts (Askins et al., 2007; North American Bird Conservation Initiative & U.S. Committee, 2011). 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. The property, referred to as Zen-Ridge, is 195 … A similar approach has been proposed that is focused on the food web and considers the mosaic associated with herbivores and fire the central goal of conservation without limiting the attention to a specific herbivore or suite of herbivores [57]. For example, the elimination of the black-tailed prairie dog (Cynomys ludovicianus) in some parts of its distribution can contribute to increased woody cover and shifts in the herbaceous plant community [35–38]. The three perspectives we present all have differing objectives. As late as 2009, there were no peer-reviewed studies that directly compared bison and cattle on large complex landscapes (greater than 300 ha). Our Objectives: Raise awareness about the need for increased conservation and protection of temperate grasslands. These three perspectives vary from an unencumbered vision to a more practical perspective that attempts to integrate regional societal objectives (table 1). We declare we have no competing interests. For one, improved monitoring of prairies and conversion would enable the focusing of policy and protection efforts on those locations of highest need. The Nature Conservancy of Canada has announced that an expanse of grasslands located south of Maple Creek is now a protected conservation site. data). In the past, the first two perspectives have been described as unlikely approaches to grassland conservation, but the progress of APR suggests that some visionary ideas may be locally important because cultural limitations change and there is considerable uncertainty in the future. Additionally, the current and impending threat of major shifts in climate is a primary limitation to most models that are focused on using the past for target conditions. Let us know! bison) then this decision is simplified considerably. Viewpoint: the black-tailed prairie dog – headed for extinction? Part of the reason grasslands are so easily lost is because many people don't recognize them as anything special, said Theo Witsell, an ecologist who cofounded the conservation … Over the past 500 years, it is difficult to disentangle the biophysical changes in North America from the cultural changes (figure 2). Humans can be considered within this model or they can be involved through making management decisions that modify both herbivore and environmental factors. Natural and semi-natural grasslands were integrated into agricultural regimes and grazing animals became intensively managed with a goal of promoting homogeneous vegetation that was often inaccurately perceived to be superior for livestock production [24,45]. will need to identify areas where private landowners and the WGFD have similar interests, and build upon those opportunities. Recognizing the importance of pri-vate land efforts to bird conservation, the National Audubon Society Endangered plants and animals are having their habitats more vigorously protected. Much of the discussion around the most appropriate approach has focused on the importance of large herbivores, as well as other disturbances in the evolution and development of flora and fauna on these landscapes [3,4]. 1. Conservation efforts have worked locally on restoring previously cultivated lands [ 23] and restoring fire regimes [ 46 ], but across the entire Great Plains, grassland fragmentation has continued through increases in energy development and woody plant encroachment and remains the primary limitation in conservation or rewilding of grasslands [ 26, 47 ]. Suggesting that we restore large herbivores or their surrogates (while ignoring small herbivores) into a novel plant community, a novel climate and a novel human population has extremely limited application potential. Timeline of the numerous changes that have occurred on the socio-ecological landscape of the North American Great Plains. The Alberta Land Stewardship Act identifies provisions to explore and test market-based conservation products (ALSA, pp. Clear differences in the life history of these species suggest that differences could be expected. The more practical approach of conservation of pattern and process seems more likely to achieve conservation goals across many fragmented landscapes in the near term because it is compatible with the current human culture of livestock and agriculture. Early and current efforts focused on managing all grasslands for moderate grazing to minimize intense disturbance has had a negative effect on agricultural production and biodiversity [10,24]. The negative impact of climate change and invasive species is predicted to be stronger in the future. The California Native Grasslands Association works to conserve grasslands throughout California through education, advocacy, research, and stewardship. Humans are, therefore, part of the plan and APR provides an example of a tentatively successful restoration of bison to large but limited areas. With the eventual settlement of most of the United States, all that was considered ‘wild’ was not tolerated and agriculture would forever alter these grassland landscapes and the species that occurred on them. The most appropriate model is dependent on the human priority of (i) restoring a certain herbivore or group of herbivores, (ii) the processes and patterns that are critical to biodiversity of all remnant grassland species and (iii) the ecological processes that provide goods and services. We evaluate each of these three conservation perspectives in terms of a framework that includes a human domain, an herbivore domain and a biophysical domain. Early calls for Pleistocene rewilding made grandiose suggestions of reintroducing mega-herbivores (or their surrogates) that went extinct not long after human arrival in North America. We do not intend to develop a comprehensive socio-ecological framework for conservation of grasslands and we question whether a single framework is even appropriate. Any differences between these species, or potentially other species, may be overwhelmed by differences in management styles that often accompany them and are associated with the human domain (figure 3) [27,29]. This rotation from one grazing spot to another mimics the natural process of herd animals grazing a landscape and allows the patches of grassland to recover before the animals return to graze them. (Online version in colour.). Management of these landscapes transitioned from hunter–gatherers to subsistence farming and eventually industrial agriculture. A conceptual model illustrating the complexity of variables that can modify the effects of any herbivore population. Figure 2. Suppression of fires may shift grassland communities from grasses and herbs towards woody-stemmed species. In order to understand the objective of this grassland tools project, a review of the relevant legislation including the Alberta Land Stewardship Act (ALSA) and the SSRP was completed. Continue education efforts, particularly among farmers, on how to protect the soil and prevent soil … There are several critical factors that are absent or limited by all of these perspectives and will probably limit their success. The mission of the Western Grassland Initiative is to serve as the primary contributor to the implementation of conservation and management actions, through partnerships and cooperative efforts, resulting in improved species status, grassland habitats, and recreational opportunities for grassland dependent species across North America.
