The nutritional value of wild plants varies greatly, and some species have nutritional values and digestibility comparable to those of commonly cultivated grass varieties. Thus, we hypothesized that foraging on seminatural grassland vegetation in abandoned fields could fulfill nutritional requirements for goat maintenance, and selective foraging could ensure greater availability of these nutrients, contributing to the maintenance of livestock and their growth. This study aimed to evaluate the nutritional value of semi-natural grassland vegetation in abandoned fields with selective foraging by goats and to estimate whether the vegetation in abandoned fields can satisfy the nutritional requirements of goats through the seasons. We used 16 goats to conduct grazing trials throughout the seasons in two experimental areas of an abandoned field. The variations in the chemical components of each plant group were also evaluated for each season. The nutritional composition of the goat ingesta was estimated from the number of bites of the ingested plant species, chemical components, and bite mass. The goats grazed on 33–43 plant species across the seasons, and the plants that the goats foraged changed throughout the seasons. Goats shifted their foraging from forbs to multiple other plant categories (bamboo species and the Poaceae and Cyperaceae families), increasing their intake of crude protein (CP) and minerals. Grazing under seminatural grassland vegetation in such fields allowed goats to meet their nutritional requirements of CP, calcium, magnesium, phosphorus, potassium, iron, cobalt, manganese, zinc, and chlorine and support a daily gain (DG) of 100 g throughout the season. In contrast, grazing in seminatural grassland vegetation caused excess Fe intake and deficiencies in selenium and copper. However, this study suggests that goats grazing under seminatural grassland vegetation in abandoned Japanese fields could support the nutritional requirements for a DG of 100 g in terms of CP and several minerals.
野生植物的营养价值差异很大,有些品种的营养价值和消化率与普通栽培的牧草品种相当。因此,我们假设在废弃地的半天然草地植被上觅食可以满足山羊维持的营养需求,并且选择性觅食可以确保这些营养物质的更大可用性,有助于维持牲畜的生长和生长。本研究旨在评价山羊选择性采食撂荒地半天然草地植被的营养价值,评估撂荒地植被是否能满足山羊的四季营养需求。我们用16只山羊在一块废弃田地的两个试验区进行了整个季节的放牧试验。还对各植物组化学成分在不同季节的变化进行了评价。根据所食植物种类的咬数、化学成分和咬质量来估计山羊食入物的营养成分。山羊在不同季节以33 ~ 43种植物为食,山羊觅食的植物种类随季节变化而变化。山羊的取食从牧草转向多种其他植物类别(竹类、禾本科和苏科),增加了其粗蛋白质(CP)和矿物质的摄入量。在这些草场的半天然草地植被下放牧,山羊可以满足CP、钙、镁、磷、钾、铁、钴、锰、锌和氯的营养需求,并在整个季节维持100克的日增重(DG)。半天然草地植被放牧导致铁摄入过量,硒和铜缺乏。然而,本研究表明,在日本撂撂地半天然草地植被下放牧的山羊在CP和几种矿物质方面可以满足100 g DG的营养需求。

Alpine grasslands in the Three River Headwater (TRH) region have suffered serious degradation owing to global climate change and human activity. Fencing is a major countermeasure implemented in the TRH region by the Ecological Protection and Restoration Program (EPRP) launched by the Chinese government. Fencing from the EPRP was to guarantee prohibited grazing during the growing season and rotation grazing during the cold season in the cold-season pasture. However, fencing excluded grazing over the entire growing season in previous studies, which was quite different from the EPRP. Thus, the protective effect of fencing from the EPRP in the TRH region cannot be confirmed based on previous studies. This study presents trends in vegetative and reproductive branch heights, vegetation cover, and aboveground biomass from 2005 to 2017, using ordinary least squares regression based on field observation data from 39 fenced sites from the EPRP in the TRH region. The results indicated that vegetative branch height, reproductive branch height, and vegetation cover decreased significantly by 34.8%, 38.2%, and 5.4%, respectively, over the study period (P < 0.05). The biomass proportion of Gramineae and Cyperaceae decreased by 48.2% and 23.9%, respectively (P < 0.05), whereas those of poisonous weeds and edible forbs increased by 170.3% and 42.0% (P < 0.10), respectively. This indicated a decrease in grassland quality at the fenced sites from the EPRP. The decrease in grassland quality may have been mainly caused by severe livestock overloading during the cold season. A competitive edge from forbs and poisonous weeds under fencing in degraded alpine grasslands may have further exacerbated grassland degradation. These results suggest that fencing in cold-season pasture from the EPRP did not achieve the objective of restoring grasslands under severe livestock overloading in the TRH region over the study period. These findings provide a significant basis for improving ecological protection and restoration policies in the TRH region.
由于全球气候变化和人类活动的影响,三江源地区的高寒草地遭受了严重的退化。围栏是中国政府实施的生态保护与修复工程在青藏高原地区实施的一项重大对策。EPRP的围栏是为了保证生长季节的禁牧和寒冷季节的轮牧。然而,以往的研究中围栏排除了整个生长季节的放牧,这与EPRP有很大的不同。因此,根据以往的研究,围栏对TRH区EPRP的保护作用无法得到证实。利用2005 - 2017年TRH地区39个EPRP围栏样点的野外观测数据,利用普通最小二乘法分析了植被和生殖枝高、植被覆盖度和地上生物量的变化趋势。结果表明:研究期间,营养枝高、生殖枝高和植被盖度分别显著降低34.8%、38.2%和5.4% (P < 0.05)。禾本科和苏科的生物量比例分别下降了48.2%和23.9% (P < 0.05),毒草和可食牧草的生物量比例分别增加了170.3%和42.0% (P < 0.10)。这表明EPRP对围栏样地草地质量的影响有所下降。草原质量下降的主要原因可能是寒季牲畜超载严重。在已退化的高寒草地上,篱下杂草和毒草的竞争优势可能进一步加剧了草地的退化。这些结果表明,在研究期间,青藏高原冷季牧场围篱并没有达到恢复草原的目的。这些发现为完善TRH地区的生态保护和恢复政策提供了重要依据。

Summer dormant perennial grasses in the annual rangelands of California’s foothills must be managed to maintain productivity. Weed invasion can reduce forage quality and stand persistence and information is lacking on best practices for weed management. Trials were established to assess the effects of indaziflam, rimsulfuron, and aminopyralid herbicides on nine perennial grass species. Herbicide treatments were applied seven years after planting and effects on crop coverage and forage biomass production were evaluated for two growing seasons. Treatment effects on weed populations, perennial grass coverage, and forage biomass varied by planted species. Generally, medusahead invasion was promoted by rimsulfuron treatments, yellow star-thistle was only abundant in the unplanted control, and hare barley was reduced by aminopyralid and indaziflam treatments. The lowest perennial grass coverage was typically observed in the untreated control and the lowest biomass was typically associated with indaziflam treatments. Coverage of wheatgrass and orchard grass varieties was improved by indaziflam treatments. Coverage of Harding grass varieties tended to be greatest in plots treated with rimsulfuron and the highest overall biomass and coverage was achieved in "Perla" koleagrass treated with 70 g ai ha-1 rimsulfuron. Aminopyralid treatments resulted in variable crop coverage effects, but often improved forage biomass through promotion of annual ryegrass.
加州山麓一年生牧场的夏季休眠多年生草必须加以管理,以保持生产力。杂草入侵会降低牧草质量和林分持久性,而且缺乏关于杂草管理最佳做法的信息。建立了吲哚氟仑、利姆磺隆和氨基吡啶类除草剂对9种多年生牧草的药效试验。在种植7年后施用除草剂,对作物盖度和牧草生物量的影响进行了两个生长季节的评估。处理对杂草种群、多年生牧草盖度和牧草生物量的影响因种而异。一般情况下,利姆磺隆处理促进了medusahead的入侵,黄星蓟只在未种植的对照中大量繁殖,而氨基吡啶和茚地夫兰处理减少了大麦的入侵。多年生牧草盖度最低的典型是未处理对照,而生物量最低的典型是茚地氟姆处理。茚地夫兰处理提高了小麦草和果园草品种的盖度。施硝磺隆处理的哈定草品种盖度最高,施硝磺隆70 g的“Perla”草总生物量和盖度最高。氨毒处理对作物盖度的影响不尽相同,但通常通过促进一年生黑麦草的生长来提高牧草生物量。

Long-Term Legacy of Juniper Encroachment: Increased Infiltration and Reduced Compaction a Decade After Mortality 桧树入侵的长期遗产:死亡后十年增加渗透和减少压实

Woody plant encroachment has altered many rangelands across North America, not only causing substantial changes in ecological and biophysical processes but often converting vast areas of grasslands and savannas into closed-canopy woodlands. While much research has documented impacts that living trees have on their surroundings (such as increases in soil infiltration and organic matter), very little is known about the legacy left by trees after their death or removal. In this study, we examined the legacy of juniper trees, one of the most widespread encroaching woody genera across North America, in the Edwards Plateau region of Texas that were determined to have died during a drought in 2011. Data were collected under canopies of both dead and living junipers, as well as in herbaceous intercanopy, where no trees are known to have grown. The parameters measured were soil infiltrability and compaction. We found that infiltrability of soils under canopies of both live (776 mm h-1) and dead (501 mm h-1) trees were significantly higher than in intercanopy areas (132 mm h-1). Soil compaction was significantly lower under dead trees than in the intercanopy spaces, though compaction under live trees was not significantly distinct. These results suggest that even 10 years after tree death, the positive influences on soil physical properties persist or increase. Further, our findings suggest that the process of juniper encroachment and subsequent dieback (due to either natural causes or management practices) may be an effective method for improving long-term soil development.
木本植物的入侵改变了北美的许多牧场,不仅引起了生态和生物物理过程的实质性变化,而且经常将大片草原和稀树草原转变为封闭的林冠林地。虽然许多研究已经记录了活的树木对周围环境的影响(例如土壤渗透和有机物质的增加),但对树木死亡或移除后留下的遗产知之甚少。在这项研究中,我们研究了德克萨斯州爱德华兹高原地区2011年干旱期间死亡的杜松树的遗产,这是北美最普遍的木本属之一。数据是在死桧和活桧的树冠下收集的,以及在没有树木生长的草本树冠间收集的。测量的参数为土壤渗透性和压实性。研究发现,活树(776 mm h-1)和死树(501 mm h-1)树冠下土壤的渗透性均显著高于树冠间(132 mm h-1)。枯树下土壤压实度显著低于林间空间,而活树下土壤压实度差异不显著。这些结果表明,即使树木死亡10年后,对土壤物理性质的积极影响仍然存在或增加。此外,我们的研究结果表明,杜松入侵和随后的枯死(由于自然原因或管理措施)可能是改善土壤长期发展的有效方法。

Formal monitoring is widely promoted by scientists, range professionals, Extension services, and conservation organizations in the U.S. as a tool for ranchers to develop knowledge about the condition of pasture and rangelands and to improve management decisions. Despite extensive scientific literature on formal monitoring, informal monitoring—such as visual assessments, systematic observations, and photography—has received limited attention. Through qualitative interviews with ranchers (n = 63) across three U.S. ecoregions (MI, OK/TX, WY/CO), this study explores how ranchers define and utilize both formal and informal monitoring methods. We found that formal, “scientific,” monitoring methods are often underutilized due to time constraints, labor demands, perceived irrelevance, and the inadequacy of data to capture localized variability that ranchers observe and manage. Conversely, ranchers predominantly use informal monitoring methods to develop local knowledge, track changes, and make management decisions tailored to their specific conditions. Considering our findings, we urge scientists and professionals to acknowledge and engage with the informal monitoring methods ranchers use, which may be outside of the scientific paradigm. We discuss future research and collaboration opportunities to integrate ranchers' informal monitoring approaches with formal methods to develop monitoring programs that are both useful and used, enhancing decision-making and outcomes on pasture and rangelands.
在美国,科学家、牧场专业人员、推广服务和保护组织广泛提倡正式的监测,作为牧场主了解牧场和牧场状况并改进管理决策的一种工具。尽管有大量关于正式监测的科学文献,但非正式监测——如视觉评估、系统观察和摄影——受到的关注有限。通过对美国三个生态区(MI, OK/TX, WY/CO)的牧场主进行定性访谈(n = 63),本研究探讨了牧场主如何定义和利用正式和非正式的监测方法。我们发现,由于时间限制、劳动力需求、感知的不相关性以及数据不足,正式的、“科学的”监测方法往往没有得到充分利用,无法捕捉牧场主观察和管理的局部变化。相反,牧场主主要使用非正式的监测方法来发展当地知识,跟踪变化,并根据他们的具体情况做出管理决策。考虑到我们的发现,我们敦促科学家和专业人士承认并参与牧场主使用的非正式监测方法,这可能超出了科学范式。我们讨论了未来的研究和合作机会,将牧场主的非正式监测方法与正式方法结合起来,制定有用和使用的监测计划,提高牧场和牧场的决策和成果。

Against the backdrop of increasing contradictions between economic development and ecological protection in pastoral areas, issues such as rangeland fragmentation and ecological degradation have gradually emerged. These issues severely restrict the modernization process of rangeland animal husbandry. Based on field survey data from 427 pastoral households in Inner Mongolia and Xinjiang pastoral areas, this paper constructs a theoretical framework of “rangeland transfer - rangeland pressure - rangeland ecology - herdsmen’s income.” It employs multiple linear regression and mediation effect models to explore the influence mechanism of rangeland transfer on pastoral income. It also examines the mediating role of rangeland pressure and the moderating effect of ecological degradation. The study finds that rangeland transfer can effectively increase pastoral households’ income. For those who rent-in rangeland, the effect of boosting pastoral income is more prominent. Those who rent-out rangeland achieve nonpastoral income growth through labor transfer. Rangeland pressure fully mediates the positive effect of rangeland transfer on herdsmen’s household income. However, the negative moderating effect of ecological changes on this mediation is obscured. Further analysis shows that the majority of herdsmen transfer rangeland based on kinship, geographical proximity, or policy guidance. Herders rarely get paid by users for ecologically degraded rangelands because of family relationships or a lack of legal knowledge.

在牧区经济发展与生态保护矛盾日益突出的背景下,草原破碎化、生态退化等问题逐渐显现。这些问题严重制约了草原畜牧业的现代化进程。本文以内蒙古和新疆牧区427户牧民的实地调查数据为基础,构建了“牧场转移-牧场压力-牧场生态-牧民收入”的理论框架。运用多元线性回归和中介效应模型,探讨了草地流转对牧民收入的影响机制。本文还探讨了牧地压力的中介作用和生态退化的调节作用。研究发现,牧地流转能有效提高牧户收入。对于以牧场为租用地的农户来说,提高牧区收入的效果更为突出。牧场出租者通过劳动力转移实现了非牧区收入的增长。牧场压力充分中介了牧场流转对牧民家庭收入的正向影响。然而,生态变化对这一中介的负调节作用并不明显。进一步分析表明,牧民转移牧场的主要原因是亲属关系、地理邻近或政策引导。由于家庭关系或缺乏法律知识,牧民很少从生态退化的牧场获得报酬。同时,政府监管的缺失降低了违反合同的代价,导致牧场退化仍然增加收入的现象。研究揭示了草地牧区生态与经济相互作用的动力机制。建议建立智能监控系统,加强监管执法。这些措施旨在促进牧区草地资源的优化配置和可持续发展。

These issues severely restrict the modernization process of rangeland animal husbandry. Based on field survey data from 427 pastoral households in Inner Mongolia and Xinjiang pastoral areas, this paper constructs a theoretical framework of “rangeland transfer - rangeland pressure - rangeland ecology - herdsmen’s income.” It employs multiple linear regression and mediation effect models to explore the influence mechanism of rangeland transfer on pastoral income. It also examines the mediating role of rangeland pressure and the moderating effect of ecological degradation. The study finds that rangeland transfer can effectively increase pastoral households’ income. For those who rent-in rangeland, the effect of boosting pastoral income is more prominent. Those who rent-out rangeland achieve nonpastoral income growth through labor transfer. Rangeland pressure fully mediates the positive effect of rangeland transfer on herdsmen’s household income. However, the negative moderating effect of ecological changes on this mediation is obscured. Further analysis shows that the majority of herdsmen transfer rangeland based on kinship, geographical proximity, or policy guidance. Herders rarely get paid by users for ecologically degraded rangelands because of family relationships or a lack of legal knowledge. Concurrently, the absence of government oversight lowers the price of contract violations, resulting in a phenomenon where rangeland degradation still increases income.

Landscape-scale ecosystem degradation in the western United States has been attributed to altered fire regimes, tree expansion into shrublands, and the invasion of exotic annual grasses. These changes have impacted populations of many wildlife species, including mule deer (Odocoileus hemionus). We examined how wildfire, dominant vegetation type, western juniper (Juniperus occidentalis) cover, vegetation productivity, and elevation influenced seasonal habitat selection for a population of mule deer that exhibits mixed-migration strategies. We used 51 416 global positioning system locations collected from adult (>1.5-yr-old) female mule deer to develop three separate population-level resource selection functions for the shared winter range (n = 148; December–March) and migratory summer range (n = 94; June–August), and resident summer range (n = 34). We found that both migratory and resident deer used older burns (11–20 yr) on summer ranges. Conversely, deer used more recent burns (<10 yr) more than unburned areas during winter. During the winter, deer also used areas with little juniper cover (<10%) and patches dominated by exotic grass. Our results indicate that wildfire has both positive and negative effects on mule deer habitat selection, depending on the season and age of burn. Furthermore, our results identify a threshold of juniper canopy cover selected by mule deer on their winter range.
美国西部景观尺度的生态系统退化被认为是由于火灾制度的改变、树木向灌木地的扩张以及外来一年生草的入侵。这些变化影响了许多野生动物物种的种群,包括骡鹿(Odocoileus hemionus)。我们研究了野火、优势植被类型、西部杜松(Juniperus occidentalis)覆盖、植被生产力和海拔如何影响具有混合迁移策略的骡鹿种群的季节性栖息地选择。我们利用从成年(>;1.5岁)雌性骡鹿收集的51 416个全球定位系统位置,开发了三个单独的种群水平资源选择函数,用于共享冬季范围(n = 148;12 - 3月)和夏季迁徙范围(n = 94;6 - 8月)和夏季栖息区(n = 34)。我们发现,在夏季范围内,迁徙鹿和居住鹿都使用较老的烧伤(11-20年)。相反,鹿在冬季使用较新的烧伤(<;10年)比未燃烧的区域更多。在冬季,鹿也会在杜松覆盖较少的地区(10%)和以外来草为主的斑块中活动。研究结果表明,野火对骡鹿生境选择既有积极影响,也有消极影响,这取决于燃烧的季节和年龄。此外,我们的结果还确定了骡鹿在其冬季活动范围内选择的杜松冠层覆盖阈值。

Rangeland fires can quickly change the structure of wildlife habitat and cause changes that persist for years to decades. To facilitate habitat recovery, postfire restoration actions often involve sowing seeds of native and nonnative perennial grasses and shrubs. Empirical information on whether such restoration activities are effective and how wildlife will respond is unknown. We evaluated the effects of wildfire and postfire seeding on rodent communities in sagebrush steppe by measuring environmental characteristics and live-trapping rodents at three wildfire locations in the northern Great Basin that burned 2–14 yr prior. Sampled plots were either 1) burned (control), 2) burned and seeded with nonnative species, 3) burned and seeded with native species, or 4) not burned (reference). Unburned reference plots had 95.7% more shrub cover and less cover of nonnative annual grasses than all burned plots. Burned plots seeded with native species had greater cover of native perennial grasses and less bare ground compared with burned plots seeded with nonnative species or control plots. Wildfire and postfire seeding significantly changed rodent community composition but not species richness. American deermouse (Peromyscus maniculatus) and least chipmunk (Tamias minimus) were less likely to occur in burned plots than in unburned reference plots. Ord’s kangaroo rat (Dipodomys ordii) and Piute ground squirrel (Urocitellus mollis) were more likely to occur in burned plots than in unburned reference plots. Sagebrush vole (Lemmiscus curtatus) was more likely to occur in burned plots with native seeding than with all other treatments. Species’ responses to wildfire and seeding reflected their relationships to cover of shrubs, perennial grasses, and nonnative annual grasses. These results suggest that wildfire and postfire seeding have long-lasting effects on wildlife communities. Landscape-level rodent diversity may be enhanced when small-scale disturbances or restoration actions increase landscape heterogeneity.
牧场火灾可以迅速改变野生动物栖息地的结构,并导致持续数年至数十年的变化。为了促进栖息地的恢复,火灾后的恢复行动通常包括播种本地和非本地多年生草和灌木的种子。关于这种恢复活动是否有效以及野生动物将如何反应的经验信息尚不清楚。通过测量2-14年前大盆地北部三个野火地点的环境特征和捕获啮齿动物,我们评估了野火和火灾后播种对鼠类群落的影响。采样样地分为1)焚烧(对照)、2)焚烧后播种非本地物种、3)焚烧后播种本地物种和4)不焚烧(对照)。未烧毁参考样地的灌木盖度比所有烧毁样地高95.7%,而非本地一年生草盖度比所有烧毁样地低。与外源种和对照地相比,以本地种播种的烧毁样地的本地多年生牧草盖度更高,裸地较少。野火和火灾后播种对啮齿动物群落组成有显著影响,但对物种丰富度没有显著影响。美洲鹿鼠(Peromyscus maniculatus)和最小花栗鼠(Tamias minimus)在燃烧样地出现的可能性低于未燃烧样地。大袋鼠鼠(Dipodomys ordii)和普特地松鼠(Urocitellus mollis)在燃烧样地比未燃烧样地更容易发生。山楂田鼠(Lemmiscus curtatus)在烧地发生的几率高于其他处理。物种对野火和播种的响应反映了它们与灌木、多年生禾本科和外来一年生禾本科植被覆盖的关系。这些结果表明,野火和火灾后播种对野生动物群落有长期影响。当小规模干扰或恢复活动增加景观异质性时,景观级啮齿动物多样性可能会增强。
