We examined the ability of an ecosystem-based framework for sagebrush conservation, the sagebrush conservation design (SCD) strategy, and the associated model of sagebrush ecological integrity (SEI), to identify and rank priority habitats for sage-grouse, a sagebrush indicator species. We compared sage-grouse population trends from 1996–2021 across the three ranked SEI categories. We then modeled those trends directly as a function of the same landcover predictors underlying SEI, used the median trend estimates to recategorize the sage-grouse's range, and used spatial correlation methods to compare our sage-grouse performance categories with those of SEI. Finally, we compared the sage-grouse condition categories, predicted by our landcover-based model, to empirical trends derived from population count data. We found that the SCD and SEI were effective tools for identifying and ranking priority habitats for sage-grouse. Population trends were stable in the core areas identified by SEI but declining in the lower (i.e., growth and other) condition categories. As a result, core areas encompassed an increasingly larger share of the total sage-grouse population in a disproportionately smaller area. Our model supports the general functional relationships between landcover and sage-grouse performance suggested by SEI. We found strong spatial congruence between our categories of predicted sage-grouse population performance, the condition categories of SEI, and empirical trends derived from population count data. Our analysis demonstrates that proactive ecosystem-based approaches to the conservation of the sagebrush biome can help optimize the return on limited conservation resources and benefits for sagebrush obligate species and help reduce some of the real and perceived conflicts inherent in single-species management.</div></div>","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":"97 ","pages":"Pages 146-159"},"PeriodicalIF":2.4,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142437886","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}

Tree removal is a widespread strategy to restore ecosystem services and biodiversity in impacted landscapes. However, tree removal can also increase the risk of invasion by exotic annual grasses. In western North America, juniper (<em>Juniperus spp.</em>) encroachment threatens the ecological integrity of intact sagebrush (<em>Artemisia tridentata</em>) shrublands. We used remote sensing to track vegetation changes following juniper removals on 288 parcels totaling 106 333 ha in southern Idaho, USA. We also analyzed vegetation changes following 64 wildfires that burned 152 611 ha of nearby rangeland during the same period. We matched areas within removals and wildfires to similar undisturbed areas, and then used causal impact analysis to estimate the effects of the disturbances. Juniper removals resulted in sustained reduction of tree cover and increased perennial forb and grass cover across nearly all sites, achieving key management goals. Based on the metrics evaluated, juniper removal was more effective than wildfire in delivering long-term restoration in this sagebrush system. However, juniper treatments also stimulated temporary undesirable increases in annual grasses and forbs, indicating the need for additional management to achieve durable conservation outcomes. Intensive mechanical methods initially reduced shrub cover in some treatments, but shrubs recovered to near pre-treatment levels within 7 years.

Historically, conservation decisions in the biome have been driven by wildlife species-specific demands, but increasing recognition of the scale of threats and the pace of ecosystem degradation has compelled a shift towards threat-based ecosystem management. Therefore, there is a need to evaluate the scale of conservation implementation relative to the rate of degradation or loss from specific threats to the biome to assess whether a conservation deficit exists. To this end, we: 1) quantified and compared the average hectares of conservation practices implemented annually relative to the hectares of CSA loss attributed to each threat; 2) evaluated the relative amount of conservation actions in core sagebrush areas, growth opportunity areas, and other rangeland areas; and 3) assessed how much additional conservation may be needed to stop CSA declines. We then quantified how better spatial targeting and enhanced coordination might reduce the total additional amount of future conservation needed, and evaluated how an influx of resources can close the conservation gap, or the deficit between the conservation needed to offset annual loss and degradation and the capacity for conservation implementation. We found that current rates of conservation (e.g., hectares treated annually) are markedly lower than rates of CSA loss (∼10% of average annual loss). Furthermore, most conservation actions, ∼90% for some treatment types, occurred outside of CSAs likely reducing the efficacy of these conservation actions at retaining and restoring intact sagebrush rangelands. Additionally, we found that conservation efforts will need to increase by more than an order of magnitude (at least 10x) annually to halt CSA declines. However, through better spatial targeting of conservation actions, the increase in conservation needed to stop CSA loss could be reduced by 70% or more.

To combat this biome decline, western partners have unified around a common vision for sagebrush conservation by developing the Sagebrush Conservation Design, which identified high-priority areas, designated as “core sagebrush areas” (CSAs), to anchor conservation actions throughout the biome. While this conservation design did not explicitly consider the distribution or abundance of focal species, an underlying assumption has been that sagebrush-associated wildlife will benefit from actions targeting threats to the sagebrush biome. Herein, we explicitly test whether sagebrush ecological integrity (SEI), the metric used to quantify CSAs, is associated with sagebrush songbird abundance and population trends, such that CSAs provide an effective umbrella for wildlife conservation. Because species likely vary in their response to different ecological factors, we further examined the relative importance of the five components of SEI: sagebrush cover, tree cover, perennial grass cover, annual grass cover, and human modification, in structuring sagebrush songbird populations. We found substantial increases in population counts associated with increased values of SEI across three species examined: sagebrush sparrow (<em>Artemisiospiza nevadensis</em>), Brewer's sparrow (<em>Spizella breweri</em>), and sage thrasher (<em>Oreoscoptes montanus</em>). Specifically, models supported 10 times (sage thrasher), six times (Brewer's sparrow), and three times (sagebrush sparrow) higher median relative abundances in CSAs compared with surrounding areas. Further, we found strong evidence of large population declines as areas transitioned out of CSAs. Finally, although we found some species-specific differences in the relative importance of the five SEI components, generally, sagebrush cover and tree cover were more important than grass cover in influencing bird populations.

Reversing the impacts of these threats is a formidable challenge. The Sagebrush Conservation Design (SCD) emphasized that limited conservation resources should first be used to maintain Core Sagebrush Areas (CSA), and then to grow such areas where possible. The SCD heightens the ecological importance of maintaining and strategically growing CSAs. However, the fact that these areas have been identified does not mean that conservation is immediately possible or will be effective. Strategic conservation in the sagebrush biome does not only involve working in ecologically important areas; it is an approach that must explicitly acknowledge the social and administrative conditions in which individuals and organizations are making decisions. We accordingly propose that strategic, durable work can only occur in geographies of “conservation readiness,” that is, where ecological importance, social capacity, and conducive administrative conditions intersect. We offer a framework for assessing conservation readiness that functions as both an inventory and diagnostic tool, highlighting current assets while shining a light on needs and the types of activities that will create or sustain conservation readiness. We demonstrate the utility of the Conservation Readiness Framework for identifying the different roles and activities that must occur at local, mid, and regional levels to nurture conservation readiness over time. In practice, this approach contrasts with management driven solely by ecological importance and illustrates that effective conservation must also involve targeted efforts that curate both social and administrative conditions.</div></div>","PeriodicalId":49634,"journal":{"name":"Rangeland Ecology & Management","volume":"97 ","pages":"Pages 187-199"},"PeriodicalIF":2.4,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142437890","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}
