By incorporating decision science principles, frameworks, and tools, it has been demonstrated that decision-makers can increase the chances of achieving conservation aims. Setting measurable objectives, clearly documenting assumptions about the impact of available actions on a specific threat or problem, explicitly considering constraints, exploring and characterizing uncertainty, and structured deliberation on trade-offs have been identified as key elements of successful decision-making. We quantify the extent to which these five elements were utilized in published examples of decision making in conservation in both academic and conservation practice between 2009 and 2018. We found that less than 50% of identified examples included all five elements, with differences in the degree of decision science applied across five commonly used decision support approaches: adaptive management (AM), systematic conservation planning (SCP), structured decision making (SDM), multi-criteria decision analysis, and cost-effectiveness analysis. Example applications that utilized the SDM framework were limited in numbers but used on average more than 50% of the five key elements we considered. Although SCP and AM constituted the majority of examples, they were more prevalent in academic studies rather than management applications.

India's Project Cheetah was tasked to restore the cheetah in parts of its historical distribution range (Jhala, Ranjitsinh, et al., &lt;span&gt;2021&lt;/span&gt;) and has received widespread public and political support while also sparking scientific debate (Gopalaswamy et al., &lt;span&gt;2022&lt;/span&gt;; Tordiffe et al., &lt;span&gt;2023&lt;/span&gt;). One challenge is the need for baseline information on cheetah ecology in India due to the extinction of the species in the mid-20th century.&lt;/p&gt;&lt;p&gt;Wachter et al. (&lt;span&gt;2023&lt;/span&gt;) provide a series of carefully formulated predictions on the potential space use of cheetahs in India's Kuno National Park (KNP) based on their perspective from a detailed understanding of cheetah spatial ecology in Namibia (e.g., Melzheimer et al., &lt;span&gt;2018&lt;/span&gt;, &lt;span&gt;2020&lt;/span&gt;). While we appreciate these insights, we address some contextual challenges that could affect the space use assumption on which their predictions build, we caution on the limitations of extrapolation, and discuss some of the management strategies that address the ranging patterns of released cheetahs in India.&lt;/p&gt;&lt;p&gt;In stating that male territories are separated by 20–23 km, Wachter et al. (&lt;span&gt;2023&lt;/span&gt;) base their predictions of cheetah movements in India on data they collected primarily in the Namibian Kalahari savannah and on interpreting data from the Serengeti (Caro, &lt;span&gt;1994&lt;/span&gt;). Both ecosystems are distinct from KNP and while these two African systems have some differences, they comprise predominantly open vegetation, are relatively flat, with few and localized natural or anthropogenic barriers, and some of the world's lowest human population densities. In contrast, KNP is a more densely vegetated landscape with large watercourses some of which may be barriers to cheetah movement. Anthropogenic activity and domestic dogs in/near villages surrounding the park are likely strong deterrents through visual, audible, and physical disturbance. Differences in cheetah space use tactics are therefore foreseen and will likely affect all Wachter et al.

(&lt;span&gt;2023&lt;/span&gt;) mention in Prediction 3, individual cheetahs are expected to test the permeability of barriers and make large exploratory movements, particularly in the early stages of post-release (Walker et al., &lt;span&gt;2022&lt;/span&gt;). Such exploratory movements can connect established populations in the future but have the potential to cause conflict. To tackle such challenges, Project Cheetah has rapid response teams tasked with actively deterring cheetahs from risky areas.

Ensuring that there are sufficient rangers in protected areas, and that these rangers are equipped and provided with decent working conditions, is critical to protecting iconic species such as tiger <i>Panthera tigris</i>. Using data from a global survey of public-sector ranger numbers, we estimate the shortfall in the number of rangers required to safeguard protected areas in Tiger Conservation Landscapes (TCLs) across the 10 Asian countries with breeding tigers. We calculate the cost required to address this shortfall in ranger numbers. We also estimate the costs for meeting a subset of the welfare needs of rangers aligned to the Chitwan Declaration of the World Ranger Congress. We estimate that a minimum of 12,500 more rangers are required across ~320,000 km<sup>2</sup> of tiger-bearing protected areas. We estimate this would cost US$ 45.8 million annually. The majority (63%) of these rangers are required in three Southeast Asian countries, which have declining tiger numbers. To meet a subset of the basic welfare needs of rangers, we estimate that an additional US$ 7.8 million is required annually across the 10 countries. While the funding gap that we estimate excludes many aspects of effective protected area management, we provide further evidence that protected areas in the biodiverse tropics remain underfunded. Increasing funding for rangers is a critical component of what is required to protect the tiger and tiger landscapes. We urge tiger range country governments, and the global conservation community, to secure this funding. Increasing the numbers of rangers, and effectively supporting their welfare, will increase our ability to protect the tiger and the ecologically significant landscapes in which it occurs.</p>","PeriodicalId":51337,"journal":{"name":"Conservation Science and Practice","volume":"6 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/csp2.13157","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141583949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This study investigated whether complete or partial refugia from elephant utilization existed for baobabs, and whether protection of trees by management, using wire netting or log- or rock-packs around a tree base, had been effective. A total of 563 baobabs were sampled across northern GNP. Elephants had debarked 99% of trees to some degree, and gouged holes in the stem of 22% of trees. The probability, and severity, of debarking and gouging decreased with increasing distance to permanent water, increasing slope, and the amount of boulder cover. Slope gradient had the greatest effect on elephant impact, with trees located on steep slopes being less affected by elephants than those on flat ground. Distance to water had an effect despite the farthest tree, at 9 km from water, being within the 15 km foraging range of bull elephants. Large boulders partly protected trees even on gentle terrain. None of these factors provided a complete refuge from elephant impact within GNP, but, individually and collectively, provided a partial refuge at current elephant densities. Protection measures doubled tree survival over approximately 5 years, with fencing wire wrapped around baobab stems proving to be the most effective method. Assessment of the future security of baobabs in GNP requires knowledge of their distribution and that of the refugia provided by distance from permanent water, slope, and boulder cover.</p>","PeriodicalId":51337,"journal":{"name":"Conservation Science and Practice","volume":"6 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/csp2.13151","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141583854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

A thorough understanding of the driving forces of human decisions regarding how domestic animals are kept is therefore critical to promote the synergy of human livelihood and biodiversity conservation. Working in the Qinling Mountains of China, we conducted a multidisciplinary study using a structural equation model (SEM) to link households' demographic and economic conditions, peoples attitudes and activities with their decisions, and further investigated how such process influences the potential negative impact of free-ranging dogs on wildlife. Among 139 blood and saliva samples collected from dogs that were owned by local villagers but allowed to roam freely, 33.3% were positive for at least one of three viral infections, including canine distemper (28.2%), canine parvovirus (25.6%), and rabies virus prevalence (10.3%). SEM modeling revealed that human activity (<i>β</i> = 0.27, <i>p</i> = .012) has significantly increased dogs' potential negative impacts on wildlife by increasing the number of dogs and their direct contact with wildlife, as well as their larger movement range. Conversely, improvement in demographic and economic conditions (<i>β</i> = −0.22, <i>p</i> = .011) and human attitudes (<i>β</i> = −0.51, <i>p</i> = .013) suppresses the influence of free roaming dogs on wildlife.

To mitigate the negative impact of fragmentation in forests, conservation targets are increasingly addressing connectivity to facilitate the independent movement of species between habitat fragments to ensure genetic diversity and adaptation to climate change. In this article, we present a novel approach to identifying and prioritizing stepping stones for preserving connectivity based on national and regional biodiversity data for Austrian forest ecosystems. Our study identified forest areas where conservation measures should be taken to ensure future habitat connectivity by combining four indicator values with different requirements of a stepping stone habitat into a prioritization value. The four compounded indicators are: (i) the <i>Protect Value</i>, which includes distances to patches of protected areas with restricted management for the undisturbed development of retention areas, (ii) the <i>Connect Value</i>, which combines datasets of designated habitat corridors and connectivity areas in Austria based on landscape models and expert validation, (iii) the <i>Species Value</i> identifying species-rich areas, and (iv) the <i>Habitat Value</i> identifying biotopes of high ecological value, key biodiversity areas, and sites of favorable protection status. Nonparametric tests revealed significant differences in prioritization value among the ecoregions of Austria and therefore encourage the consideration of stepping stone prioritization at local and regional context. Building upon the insights from this case study on Austrian forest ecosystems, we developed a robust framework derived from our methodology. This framework is designed to facilitate future implementations in diverse study regions, accounting for factors beyond connectivity crucial for identifying high value stepping stone habitats. We encourage adaptation of this framework to local data availability, species requirements, and local conditions. The compiled framework provides decision support for managers and conservationists for prioritizing areas to conserve and improve connectivity of forest habitats. However, it does not substitute on-the-ground field assessments of habitat quality and measures of functional connectivity.</p>","PeriodicalId":51337,"journal":{"name":"Conservation Science and Practice","volume":"6 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/csp2.13161","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141338326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Research on how these species are impacted by forestry management decisions has advanced to provide specific conservation actions for these imperiled species. We set out to better understand the level of knowledge land managers had in relation to forestry techniques and their impact on wildlife conservation in order to more effectively strategize how we can efficiently provide educational resources. We surveyed 78 land managers in Illinois to identify their priorities for management and how familiar they were with forestry management guidelines for bat conservation. We followed up with a subset of voluntary participants with semistructured phone interviews to generate more in-depth responses. Using these tools, we reveal that a top priority for most managers in Illinois is invasive species management. Most have some familiarity with bat conservation actions, but few were confident in their knowledge of threatened and endangered species. Thirteen of the twenty phone interviews identified a preference for talking to/hearing from experts to receive information on bat conservation. These results highlighted where there are information gaps on best practices for forestry management from a conservation perspective, and identified how we can best address these through partnerships with land managers.
