This change from sagebrush removal efforts to encourage forage production to conservation and restoration had several causes, but the largest factor was the long-term decline in greater sage-grouse (<em>Centrocercus urophasianus</em>) populations and potential for listing under the Endangered Species Act. Potential for listing accelerated planning and implementation activity by the Bureau of Land Management, US Forest Service, Fish and Wildlife Service, states, nongovernmental organizations, and private landowners that continues to this day. The tremendous investment we have all made in collaborative science has set us up for success in conserving sagebrush and sagebrush obligate species. We offer insights organized around five themes and specific recommendations for moving sagebrush conservation forward. Despite over three decades of unprecedented conservation efforts, we are still losing sagebrush at a rate of 0.53 million hectares (1.3 million acres) per year, which means we must both increase our capacity for sagebrush conservation and become more strategic in our investments. Shifting the emphasis of conservation from sage-grouse to sagebrush will reduce conflicts, increase participation, and broaden benefits. Increasing capacity, both fiscal and human from biome to local scales will require effectively communicating the value of, and threats to, the sagebrush biome. Recent science products, including this issue, offer a new ability and create a responsibility to strategically target sagebrush dollars where we can be successful. This strategic approach should be adaptive, with explicit conservation goals and monitoring to evaluate progress. This will require unprecedented collaboration to establish priority areas and goals, which will necessitate a collaborative governance structure to coordinate. Toward this end, we offer 9 specific implementation recommendations.</div></div>","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142437891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 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 . Canopy injury was a critical fire severity measurement determining postfire mortality in , 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 , 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 in tallgrass prairies at an early stage.","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":null,"pages":null},"PeriodicalIF":2.3,"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}

Disturbance is an essential part of rangeland systems. Yet climate change is likely to affect rangelands most directly by increasing the likelihood, severity, and extent of long term, negative impacts from disturbance. We conducted a synthesis of key vulnerabilities to climate change for Northwest US rangelands. These rangelands are projected to become warmer and drier this century, with episodes of more extreme droughts and higher likelihood of more severe fires affecting larger areas. Many of the vulnerabilities identified in our synthesis, such as increased frequency of fire and invasive grass proliferation, can have lasting effects, leading to “undesirable transformations” (substantial and persistent changes in vegetation composition and reductions in ecosystem services). For example, larger, more severe fires have led to the rapid loss of critical Greater sage-grouse habitat and diminished forage production capacity for livestock in some areas, lowering provisioning of ecosystem services, increasing fire management costs, and impacting rural livelihoods. Rangeland managers need guidance connecting climate change projections to on-the-ground management actions. We conclude from our synthesis of climate change vulnerabilities that supporting rangeland recovery is an important climate adaptation approach on Northwest rangelands. Proactive climate adaptation strategies (e.g., supporting soil health and vegetation) and example practices (e.g., establishing climate-adapted perennial plant species) are presented according to key action areas: prepare for, respond to, and recover from disturbance. Identifying specific adaptation needs at more local scales, like the management unit level, may be further refined through proactive planning and experimentation in collaborative settings that allow for resource pooling and foster learning.","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142192453","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}

In response to these threats, various mechanical seeding methods (such as drill seeding and mechanical mixing of broadcast seeds) are commonly employed by restoration practitioners. Despite their common use, little information exists about how additional disturbance from mechanical seeding (following wildfire disturbance) may further contribute to soil loss from wind erosion. Here, we compared the effects of mechanical seeding techniques on soil properties following two wildfires occurring in similar climates with contrasting soil textures (silty loam and gravelly loam soils). Using either a rangeland or minimum-till drill to create furrows or mix broadcasted seeds into soils, we quantified wind erosion risk for unburned sites, burned nonseeded sites, and seeded sites according to soil aggregate stability, horizontal sediment flux, surface microtopography, and soil compaction. Effects of mechanical seeding were small relative to those created by wildfire. For burned areas, differences in site stability were greatest between sites. Following wildfire, the largest decrease in site stability occurred in fine-textured soils, where horizontal sediment transport was increased by nearly five orders of magnitude relative to unburned areas. Despite these initial differences, site stability in fine-textured soils may have improved to a greater degree than stability at the coarse-textured site. Furthermore, we found minimal differences between drill types on site stability but, instead, observed that the largest differences in soil properties were created by furrow versus broadcast seeding. The different outcomes of rehabilitation on site stability found here, paired with the spatial extent to which wildfire affects landscapes, highlights the importance of postfire monitoring of site stability in more locations that vary by soil, plant, landscape, and climatic variables.</p></div>","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142011309","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}

In addition, climate change may reduce habitat connectivity for mouflon in the future.

We assessed the interaction effects of grazing intensity, season, and leaf functional traits on herbivore grazing patterns in a native grassland composed of functionally diverse patches in four 10–14 ha paddocks managed under lenient or moderate grazing intensities. Seasonal botanical composition was estimated in permanent 20 × 20 cm patches. Defoliation events of species in patches were recorded every 7–10 d, four times during summer-autumn, and five times during winter and spring. Leaf dry matter content, specific area, tensile strength, and width of dominant grass species were measured seasonally, and species were allocated to functional groups. The proportion of total defoliation events occurring in each functional group and their selectivity index were estimated for each period and season. We tested the relationship between trait community weighted mean in the pasture and that grazed by cattle for each quadrant and period within seasons. Cows focused grazing on resource-acquisitive strategy species with wider and more tender leaves during summer-autumn under both grazing intensities. As herbage mass and accumulation decreased during winter, cows shifted their foraging strategy toward shorter patches and previously rejected, tougher-thinner leaves and resource-conservative strategy species stockpiled from summer-autumn, not overgrazing the resource-acquisitive species. However, this general pattern was modulated by grazing intensity; cows grazed taller patches and more tender and wider-leaved species under lenient than moderate grazing intensity. Thus, the spatiotemporal heterogeneity of desired and rejected stockpiled patches of different functional groups was managed by integrating seasonality, grazing intensity, and leaf functional traits. Therefore, the general principle of foraging selectivity toward desired species can be altered by management practices and inherent species attributes, maintaining communities of species of different ecosystem functions in equilibrium.</p></div>","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142011308","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}

Remote sensing and Geographic Information System technologies increasingly offer opportunities to generate synoptic, high-resolution characterizations of ecosites in heterogeneous and remote rangelands.

Using 1 m airborne hyperspectral reflectance data, spectral vegetation and moisture indices (derived from hyperspectral bands and rendered together with the hyperspectral stack), and aerial imagery for ground-truthing, we were able to 1) produce a classification product quantifying some, but not all, plant and soil categories used in STMs and 2) delineate the spatial pattern and areal extent of ecological states on several ecological sites. Our remote sensing-based assessments were then compared to vegetation state maps based on traditional field surveys. We found that with the exception of native vs. nonnative grass ground cover, remote sensing picked up contributions of key ecostate classification variables. Remote sensing products thus have value for planning and prioritizing field surveys and pinpointing areas of concern or novelty.
