Grasses are the dominant fuel type in rangelands. Past work has shown that grass canopy architecture, which varies among grass species, can influence flammability. Whether variation in grass fuel structure can influence postfire plant responses has not yet been tested. To bridge this gap, we set up field burning experiments with different fuel treatments and examined postfire mortality of <em>Juniperus virginiana</em> L. in a tallgrass prairie in southwestern Missouri. We sampled 60 trees and measured tree height and diameter at breast height before the fire. Fuels surrounding each tree were manipulated to vary independently in both fuel load and fuel structure. Flame temperatures were measured during the fire, and both stem and canopy injuries were evaluated 1 d after the fire. We surveyed tree mortality 7 mo after the fire. We found no effects of either fuel load or fuel structure on postfire mortality or on canopy injury in <em>J. virginiana</em>. Canopy injury was a critical fire severity measurement determining postfire mortality in <em>J. virginiana</em>, and taller trees are more fire resilient. Despite laboratory-observed fuel structure effects on flammability, this study finds no evidence for the importance of grass fuel load and canopy architecture in influencing postfire tree response. This result might arise from the low crown depth and low canopy water content of <em>J. virginiana</em>, which can promote canopy fire and result in a high mortality rate across fuel treatments. Notwithstanding the negative results, testing laboratory-based findings in field settings is important for further examining laboratory observations and upscaling individual-level processes to ecosystems to help identify the key ecological processes determining population dynamics and community assembly. Our study also suggests that prescribed fire is an effective tool to remove encroaching <em>J. virginiana</em> in tallgrass prairies at an early stage.</div></div>","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":"98 ","pages":"Pages 110-117"},"PeriodicalIF":2.4,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The invasion of Eastern red cedar (<em>Juniperus virginiana)</em> across the Great Plains due to fire suppression is limiting grazeable land for cattle. Woody plant encroachment (WPE), combined with drought impacts and high input costs, becomes expensive for cattle producers who are forced to supplement, destock, or both. Patch-burn grazing is a practice based on the understanding of the interaction of fire and grazing (pyric herbivory) that divides a pasture into sections, burning one section rotationally each year. It offers improved rangeland productivity by providing high-quality forages, mitigation for drought impacts, and control of WPE. Despite these benefits, the adoption of patch-burn grazing by cattle producers is limited. Our goal involved increasing awareness of the benefits of patch-burn grazing by estimating the costs and long-term economic benefits and comparing them to those of one of the more traditional approaches of burning an entire pasture every 3 yr. In building an economic analysis, our objectives were to calculate utilization costs and quantify the benefits of high-quality forages and drought impact mitigation.</div><div>Results indicated that patch-burn grazing will cost approximately $5.94 more per hectare per year than burning the entire pasture every 3 yr.

Additionally, utilizing patch-burn grazing before a drought, not burning during a drought, and resuming after the drought reduce supplementation and burn costs by 4.5% and increase future value of savings by $100.21 per cow compared with those caused by traditional management practices after 6 yr.

Unlike historical, continuous grazing, contemporary practices generally incorporate planned periods of rest and recovery from grazing during the growing season. Dormant season grazing is one such practice that shows promise for improving degraded rangelands and reducing wildfire risk. However, no studies have compared moderate intensity dormant season grazing to contemporary spring-summer grazing and grazing exclusion in sagebrush rangelands dominated by perennial bunchgrasses. We evaluated the effects of contemporary spring-summer grazing, dormant season grazing, and grazing exclusion on plant community characteristics in a Wyoming big sagebrush ecosystem. We expected the effects of dormant season grazing to be comparable to grazing exclusion. Deep-rooted perennial bunchgrass cover and density and shallow-rooted perennial bunchgrass cover in grazed areas did not differ from grazing exclusion (control) sites, and we found no support that grazing altered the deep-rooted perennial bunchgrass community through time. Dormant season grazing reduced native annual forb and sagebrush cover, but increased density of the shallow-rooted perennial bunchgrass.

Understanding how pastoralists apply established and contemporary risk management approaches is critical for policy and planning on social protection for vulnerable communities. Hence, this study sought to describe existing informal risk-sharing approaches and explore index-based livestock insurance (IBLI) as a formal risk-sharing approach employed by pastoralists to cope with pastoral resource scarcity. Based on the socioecological and disaster approaches to resilience theory, this research employed a qualitative descriptive design. Using semistructured in-person interviews, data were collected from a sample of 69 household respondents, a focus group discussion, and 4 key informants. This study found that although social networks enhance resource sharing, adverse climate stressors were strangling the traditional resource-sharing structures of pastoralism. As a result, this study noted a potential shift from collective risk sharing to household-based or self-insurance among pastoralists. IBLI uptake was recorded as low at 17% due to low awareness levels, a slowed premium sale supply, and a plausible product trust deficit. This study affirms that formal insurance can leverage informal insurance social networks to assist households in coping better with climate shocks, thus enhancing livelihood resilience. The study recommends establishing a framework that integrates both the traditional and modern approaches to risk sharing. Additionally, a focus on designing formal risk-sharing products that cater to household and collective shock recovery may be promising.</div></div>","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":"98 ","pages":"Pages 160-169"},"PeriodicalIF":2.4,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142745711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, some invasive species thrive after disturbance, necessitating more nuanced management strategies. Managers in the Attwater Prairie Chicken National Wildlife Refuge use combinations of prescribed fire and herbicide to control the spread of Macartney rose (<em>Rosa bracteata</em>). However, literature suggests that the efficacy of such a strategy has been inconsistent, perhaps owing to differences in the seasonal timing and frequency of herbicide and burning treatments. We compared the timing of herbicide applications in relation to prescribed fire and their effects on Macartney rose by monitoring 160  ×  100 m² belt transects distributed among four categories of treatment strategy: prefire herbicide, postfire herbicide, both, or no herbicide (fire only). Prefire herbicide applications were conducted followed by prescribed fires in December 2021–January 2022, and postfire herbicide was applied in April–May 2022. We conducted plant surveys and measured Macartney rose density and cover in between and after each treatment. After all treatments, we collected arthropods by sweep netting and identified them to the order level. We also baited and collected ants and later identified and counted red imported fire ants under a microscope. We found that Macartney rose density declined by ∼40% and cover exhibited a five-fold decrease in transects that received herbicide both before and after fire, whereas plant and arthropod diversity were unchanged regardless of herbicide treatment. Prescribed fire and herbicide application are essential tools for modern coastal prairie management, but nuances regarding the different ways these tools might be combined should be considered to optimize invasive species control while limiting undesirable effects. In the case presented in this study, Macartney rose was most significantly reduced, and plant and arthropod diversity were maintained using strategies that combined fire and herbicide differently than most common practice.</div></div>","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":"98 ","pages":"Pages 237-245"},"PeriodicalIF":2.4,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Restoration of these invaded sites has been met with low levels of success. Pre-emergent herbicides can effectively control these annual weeds, but this treatment does not allow for the concurrent seeding of desired species. Seeding within a deep U-shaped furrow following herbicide application may be a method to reduce pre-emergent herbicide effects by transferring the herbicide away from the seed at the time of planting. We investigated this method by spraying plots with or without the pre-emergent herbicide imazapic, then planting with or without a deep furrow. Treatments (i.e., spraying and furrowing) were applied using mechanical equipment within a single pass at six sites. In plots without imazapic, deep furrows generally had higher plant density and more above-ground biomass of seeded species than those in plots without furrows. Similarly, in plots with imazapic, deep furrows generally improved measured plant metrics for the seeded species. For example, plant density in deep furrows was 62–97% higher than that with nonfurrow treatments in plots with imazapic and 41–89% higher in plots without imazapic. Deep furrows also decreased exotic annual weeds in the first year after planting, but weed reduction was generally more effective when this treatment was applied with imazapic. Overall, this research provides evidence that deep furrows alone can improve seeding success in most instances. Nevertheless, combining herbicide application with deep furrows in a one-pass system should be considered in areas with high weed cover. Due to the substantial soil disturbance caused by deep furrows, this method should be selectively applied, such as constraining the treatment to substantially degraded areas.</div></div>","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":"98 ","pages":"Pages 256-268"},"PeriodicalIF":2.4,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
