Ecological correlates of the popularity of birds and butterflies in Internet information resources

The success of conservation programs depends on using appropriate methods to demonstrate the importance of conservation to society. For example, flagship species are among the key marketing tools to motivate public support. However, they are rarely selected in a systematic, manner. In this study we addressed the issue of the colonization of human information resources by birds and butterflies in the context of wildlife conservation. We used a simple method to measure the popularity of species based on Google browsing and made an attempt to link biological characteristics of the species with their popularity in human information resources. Biological traits of species contributed significantly to explaining the occupancy (invasion) of cyberspace by the species. Commonness and body size of the species appeared to be the most informative predictors of their Google score. We believe that these results may be used by conservation organizations to assist in the selection of flagship/charismatic species, and their use in logos, for TV programs or for other public presentations. Moreover, we showed that some biological traits can affect the popularity of wildlife in society and in virtual resources.     

Effects of environmental factors on the distribution of flagship species in Bomfobiri Wildlife Sanctuary,Kumawu, Ghana: Implications for conservation and ecotourism development

Sustainable ecotourism development and conservation depend on understanding factors that affect flagship species. This study analysed environmental factors and their effects on flagship species: African buffalo (Syncerus caffer), red-river hog (Potamochoerus porcus), olive baboon (Papio anubis), duiker (Cephalophus spp.), and crocodile (Crocodylus niloticus) distribution in Bomfobiri Wildlife Sanctuary (BWS). Secondary data (camp reports 2017–2019) showed flagship species distribution across four vegetation types in 14 sites. Field observations were used to reconstruct camp report information using GPS coordinates to show animal distribution. Environmental factors were assessed based on the scope and severity of their threats to the species. PAST ver.3.06 was used to analyse animal and vegetation data. A total of 995 individual animals were recorded. Riverine forest (n = 325) had the highest, followed by semi-deciduous (n = 316), and woodland Savanna (n = 192). Bushfire was the major predictive factor on animal distribution, followed by grazing pressure, farming activities, elevation, and erosion. These findings imply that an increased scale of disturbances reduces the chance of sighting flagship animals. A higher concentration of these species in riverine and semi-deciduous forests calls for increased patrols as a conservation measure. Constructing viewing platforms and hiking trails in areas of higher animal activity would improve ecotourism development.     

The culture of bird conservation: Australian stakeholder values regarding iconic,flagship and rare birds

Iconic, flagship and rare threatened bird taxa attract disproportionate amounts of public attention, and are often used to enable broader conservation strategies. Yet, little is known about why certain taxa achieve iconic or flagship status. Also unclear is whether the perception of rarity among those acting to conserve threatened birds is sufficient to influence attitudes and behaviour that lead to effective conservation action and, if so, which characteristics of rare birds are important to their conservation. We interviewed 74 threatened bird conservation stakeholders to explore perceptions about iconic, flagship and rare threatened birds and classified their attitudes using a new typology of avifaunal attitudes. There was a relationship between societal interest and conservation effort for threatened species characterised as iconic, flagship and rare. Iconic species tended to arouse interest or emotion in people due to being appealing and readily encountered, thereby attracting conservation interest that can benefit other biodiversity. Flagships tended to have distinguishing physical or cultural characteristics and were used to convey conservation messages about associated biodiversity. Attitudes about rarity mostly related to a taxon’s threatened status and small population size. Rarity was important for threatened bird conservation but not always associated with attitudes and behaviour that lead to effective conservation action. We conclude that conservation action for individual threatened bird taxa is biased and directly influenced by the ways taxa are socially constructed by stakeholders, which is specific to prevailing culture and stakeholder knowledge.     

Selecting flagships for invertebrate conservation

Invertebrates have a low public profile and are seriously underrepresented in global conservation efforts. The promotion of flagship species is one way to generate interest in invertebrate conservation. Butterflies are frequently labeled invertebrate flagships, but clear definitions of the conservation actions they are meant to catalyze, and empirical assessments of their popularity amongst non-Western audiences are lacking. To improve the use of invertebrate flagships, we examine how butterflies compare with other taxa in terms of popularity. We then identify characteristics of individual species that are appealing and explore whether these may be used to derive a set of guidelines for selecting invertebrate flagships. We conducted questionnaire-based surveys amongst two target audiences: rural residents (n = 255) and tourists (n = 105) in northeast India. Invertebrates that were aesthetically appealing, or those that provided material benefits or ecological services were liked. Butterflies were the most popular group for both audiences, followed by dragonflies, honeybees and earthworms. A combination of large size and bright colours led to high popularity of individual species, whilst butterflies with unique features were liked by tourists but not rural residents. These results provide empirical evidence that butterflies appeal to diverse audiences and have the potential to be deployed as flagships in different contexts. However, prior to promoting invertebrate flagships, their intended uses need to be specified. Here we define an invertebrate flagship as an invertebrate species or group that resonates with a target audience and stimulates awareness, funding, research and policy support for the conservation of invertebrate diversity. In conclusion we outline a set of heuristic guidelines for selecting flagships to raise awareness of invertebrate diversity and conservation.     

Reconciling scientific and local ecological knowledge to identify priority mammals for conservation in a dry forest area in northeast Brazil

Species prioritization for conservation is primarily based on extinction risk assessments but less on sociocultural factors that influence conservation effectiveness. Here, we prioritized mammals for conservation according to their need for conservation attention, the feasibility of their conservation, and their potential to be used as flagship species in a rural community in northeast Brazil. We assessed species occurrence and ethnobiology through interviews, camera trapping, and active searches, and developed a prioritization scheme that accounts for species’ threat level (conservation status and local hunting pressure), cultural importance, and popularity. We found Tolypeutes tricinctus as the overall top-priority species because of its Endangered status and high popularity, which makes its conservation needed and feasible, and this species a potential conservation flagship. Panthera onca was the highest priority regarding the need for conservation attention due to its Critically Endangered status but the least feasible to conserve as it was the most unpopular species. Mazama gouazoubira was the most hunted and popular species. Despite not being threatened, it may also be prioritized for conservation, given its high hunting pressure and popularity, thereby constituting a possible local flagship species. Our results show that priority species for conservation can be reliably identified based on measures of need for conservation attention and expected conservation feasibility in local scales using rapid assessments. Accounting for ethnobiology in species prioritization for conservation allows a better understanding of the needs, opportunities, and obstacles for their conservation, consequently leading to better resource-allocation decisions in different socio-economic scenarios.     

Wildlife conservation planning under the United States Forest Service's 2012 planning rule

In 2012, the United States Forest Service (USFS) promulgated new planning regulations in accordance with the National Forest Management Act (NFMA). These regulations represent the most significant change in federal forest policy in decades and have sweeping implications for wildlife populations. We provide a brief overview of the history of the NFMA planning regulations and their wildlife provisions and review the current science on planning for effective wildlife conservation at the landscape scale. We then discuss the approach to wildlife conservation planning in the 2012 rule and compare it to alternatives that were not selected and previous iterations of the planning rule. The new planning rule is of concern because of its highly discretionary nature and the inconsistency between its intent on the one hand and operational requirements on the other. Therefore, we recommend that the USFS include in the Directives for implementing the rule commitments to directly monitor populations of selected species of conservation concern and focal species and to maintain the viability of both categories of species. Additional guidance must be included to ensure the effective selection of species of conservation concern and focal species, and these categories should overlap when possible. If the USFS determines that the planning unit is not inherently capable of maintaining viable populations of a species, this finding should be made available for scientific review and public comment, and in such cases the USFS should commit to doing nothing that would further impair the viability of such species. In cases where extrinsic factors decrease the viability of species, the USFS has an increased, not lessened, responsibility to protect those species. Monitoring plans must include trigger points that will initiate a review of management actions, and plans must include provisions to ensure monitoring takes place as planned. If wildlife provisions in forest plans are implemented so that they are enforceable and ensure consistency between intent and operational requirements, this will help to prevent the need for additional listings under the Endangered Species Act and facilitate delisting. Although the discretionary nature of the wildlife provisions in the planning rule gives cause for concern, forward-thinking USFS officials have the opportunity under the 2012 rule to create a robust and effective framework for wildlife conservation planning. © 2013 The Wildlife Society.     

Dimensions of the Human–Animal Bond and Evacuation Decisions among Pet Owners during Hurricane Ike

ABSTRACT

Flagship species play an important role in promoting nature conservation. However, although the significance of invertebrates in biodiversity and ecosystem services is undisputed, they are rarely used as flagship species. A focused approach to better understand the drivers of differences in attitudes toward invertebrates, and insects in particular, would be helpful for selecting and establishing insects as flagship species, especially in a local context for local conservation purposes. Using a standard questionnaire, a total of 363 children, predominantly aged 10 to 12 years, were asked about their attitudes toward 18 invertebrate species indigenous to Switzerland. The species, 14 insect species and four other invertebrates, were individually presented in a color photograph without any background information. Based on ordinal regression models, the survey revealed substantial affinity rating differences across the invertebrates selected. Gender, species knowledge, preferred leisure activities, and family membership of a nature protection organization proved to be significant predictors for children's attitudes in general, and for some specific species in particular. Additionally, existing species knowledge was analyzed and was found to neither depend on school location (urban/rural) nor on gender. The authors propose the inclusion of local invertebrates and species knowledge in the curriculum in early years at primary school while applying teaching methods that allow for real-life experience.     

Mobilizing metaphors: the popular use of keystone,flagship and umbrella species concepts

Misrepresentation of terminology is a major impediment for attempts at enhancing public conservation literacy. Despite being critically important for improving conservation practice, there have been few systematic analyses of the popular use of conservation terminology. This paper draws from science communication studies and metaphor analysis, to examine how keystone, flagship and umbrella species concepts are used and represented in non-academic contexts. 557 news articles containing these terms were systematically analyzed. Mammals featured in 60% of articles on keystones, 55% on flagships and 63% on umbrella species. Number of articles explaining the terms keystone (35%) and flagship (31%) was low, and keystones were the most misrepresented term. Keystones were metaphorically linked with balance, flagships with representation and umbrella species with protection. These metaphors influenced public interpretation of scientific terminology, oriented actions towards select species, and led to a valuation of such actions. Together, the findings highlight three important aspects of popular use of conservation terminology: (1) communication is largely biased towards mammals, (2) everyday language plays a vital role in the interpretation of concepts, and (3) metaphors influence peoples’ actions and understanding. Conservation biologists need to engage with issues of language if public conservation literacy is to be improved. Further evaluations of concepts with high public and policy relevance, systematic identification of communication shortfalls, and linguistic assessments prior to promoting new terms are potential ways of achieving this.     

Population size estimation of an Asian elephant population in eastern Cambodia through non-invasive mark-recapture sampling

The Asian elephant is a flagship species for conservation in tropical Asia, but reliable population estimates are available only from a few populations. This is because the species can be elusive and occurs at low densities in dense habitat over a large part of its range. Phnom Prich Wildlife Sanctuary in the Eastern Plains, Cambodia, which is part of one of the largest protected area complexes in South-East Asia, is one such habitat that had not been systematically censused for elephants. We, therefore, used fecal-DNA based capture-mark-recapture sampling to estimate the population size for establishing a monitoring baseline. Five sampling sessions targeted all areas in and adjacent to Phnom Prich Wildlife Sanctuary believed to be used by elephants. Fresh dung was collected as the source of DNA and genotyping was carried out based on nine microsatellite loci. The 224 samples collected yielded 78 unique genotypes. Using model averaging of closed population capture-mark-recapture models, the elephant population in Phnom Prich Wildlife Sanctuary was estimated to number 136 ± 18 (SE) individuals. Our results suggest that eastern Cambodia supports a regionally important Asian elephant population.     

Biodiversity gains from efficient use of private sponsorship for flagship species conservation

To address the global extinction crisis, both efficient use of existing conservation funding and new sources of funding are vital. Private sponsorship of charismatic ‘flagship’ species conservation represents an important source of new funding, but has been criticized as being inefficient. However, the ancillary benefits of privately sponsored flagship species conservation via actions benefiting other species have not been quantified, nor have the benefits of incorporating such sponsorship into objective prioritization protocols. Here, we use a comprehensive dataset of conservation actions for the 700 most threatened species in New Zealand to examine the potential biodiversity gains from national private flagship species sponsorship programmes. We find that private funding for flagship species can clearly result in additional species and phylogenetic diversity conserved, via conservation actions shared with other species. When private flagship species funding is incorporated into a prioritization protocol to preferentially sponsor shared actions, expected gains can be more than doubled. However, these gains are consistently smaller than expected gains in a hypothetical scenario where private funding could be optimally allocated among all threatened species. We recommend integrating private sponsorship of flagship species into objective prioritization protocols to sponsor efficient actions that maximize biodiversity gains, or wherever possible, encouraging private donations for broader biodiversity goals.     

History of weta (Orthoptera: Anostostomatidae) translocation in New Zealand: lessons learned, islands as sanctuaries and the future

Establishing new populations by transferring founder individuals from source populations has been effective for managing the recovery of many threatened species including some weta (Orthoptera: Anostostomatidae) in New Zealand. These large-bodied flightless insects are ‘flagship species’ for insect conservation in New Zealand and many are rare or threatened. The declining abundance of most weta species, particularly giant weta, can be attributed to the introduction of mammalian predators, habitat destruction, and habitat modification by introduced mammalian browsers. New populations of some weta have been established in locations, particularly on islands, where these threats have been eliminated or severely reduced in order to reduce the risk of extinction. Some populations were established to provide food for endemic vertebrates, ecosystem restoration and ready access for the general public. We illustrate how methods for both transferring weta and monitoring them have become more sophisticated by using a series of case studies. Other transfers of weta not included in the case studies are also summarised. We conclude by re-iterating the importance of documenting the transfer and post-release monitoring for all insect transfers, both for biogeographical reasons and to provide information to improve future transfers.     

The role of ecotourism in conservation: panacea or Pandora’s box?

Does ecotourism contribute towards conservation of threatened species and habitats or is it just a marketing ploy of the tourism industry? Using 251 case studies on ecotourism from the literature, I looked at the distribution of case studies over continents, habitats and flagship species types and what factors influenced whether an ecotourism regime was perceived as ecologically sustainable by authors. Over 50% of ecotourism case studies were reported from Africa and Central America. The overall distribution of ecotourism case studies did not reflect vertebrate endemism, nor overall tourism distribution in terms of tourist numbers and receipts. There were significant differences between continents and habitats with regard to the proportion of sustainable case studies: ecotourism is perceived to be less sustainable in South America and Asia, and in island and mountain habitats. The type of flagship species also influenced whether ecotourism was classified as sustainable or not: ecotourism with no flagship species was rarely classified as sustainable while charismatic bird and mammal species were associated with a higher probability of sustainability. In a multivariate analysis, flagship species type and local community involvement were important predictors of sustainability in ecotourism. Detailed a priori planning, local involvement and control measures were perceived by authors of case studies to increase the success of ecotourism in conservation. They also perceived that ecotourism can only be an effective conservation tool under certain conditions. If these are met, the evidence indicates that ecotourism can make a contribution to conservation.     

The value of flagship and umbrella species for restoration and sustainable development: Bale monkeys and bamboo forest in Ethiopia

Forest loss and degradation are the most significant threats to terrestrial biodiversity in the tropics. Promoting flagship or umbrella species is a strategy that can be used to conserve intact forests and restore degraded ecosystems, conserve biodiversity, and achieve sustainable development goals. The Bale monkey (Chlorocebus djamdjamensis) is an arboreal, forest-dwelling, threatened primate restricted to a small range in the southern Ethiopian Highlands, which relies mostly on a single species of bamboo (Arundinaria alpina) and prefers bamboo forest habitat. Most of the Bale monkey’s range lies outside protected areas and most of its historical bamboo forest habitat is degraded or destroyed. The conservation of Bale monkeys and bamboo is highly inter-dependent; however, the value of using the Bale monkey as a flagship or umbrella species for forest restoration has not been evaluated. Here we use geographic range overlap and geospatial modeling to evaluate Bale monkeys as a flagship and/or umbrella species. We also assess if conservation intervention on behalf of Bale monkeys can help restore bamboo forest, while simultaneously providing a wide range of socioeconomic and environmental benefits. We found that Bale monkeys share their range with 52 endemic and/or threatened vertebrate species and at least 9 endemic and/or threatened plant species. Our results show that Bale monkeys meet both the flagship and umbrella species criteria to restore bamboo forest and conserve threatened co-occurring species. Since bamboo is fast-growing and can be harvested every year, we suggest that a science-based sustainable harvest and management regime for bamboo would help to improve the livelihood of both the local community and Ethiopians in general without significantly affecting the long-term survival of Bale monkeys and regional biodiversity. Further, a conservation management strategy protecting and restoring bamboo forest has the potential to achieve at least six of the 17 United Nations Sustainable Development Goals.

A stakeholder perspective into wildlife policy in India

We investigated perceptions of wildlife policy and issues through questionnaires (n = 148) administered to policy makers, conservation scientists, individuals representing non-government organizations (NGOs), and field officials, who implemented government policies and enforced laws. We found significant differences among attitudes of stakeholders identifying major threats to wildlife, the use of science, the role of poaching in conservation, and the composition of species illegally traded. Policy makers and field officials differed in their views with NGOs and scientists on community response to wildlife policies and the varying threat perceptions to different species due to poaching and illegal trade. We noted ambiguity among stakeholders about sustainable use principles in India. Policies must be more effective in conservation and the process of making policy must be broad-based and participatory if wildlife conservation is to advance on the subcontinent. © 2011 The Wildlife Society.     

Conservation Genetics of the Philippine Tarsier: Cryptic Genetic Variation Restructures Conservation Priorities for an Island Archipelago Primate

Establishment of conservation priorities for primates is a particular concern in the island archipelagos of Southeast Asia, where rates of habitat destruction are among the highest in the world. Conservation programs require knowledge of taxonomic diversity to ensure success. The Philippine tarsier is a flagship species that promotes environmental awareness and a thriving ecotourism economy in the Philippines. However, assessment of its conservation status has been impeded by taxonomic uncertainty, a paucity of field studies, and a lack of vouchered specimens and genetic samples available for study in biodiversity repositories. Consequently, conservation priorities are unclear. In this study we use mitochondrial and nuclear DNA to empirically infer geographic partitioning of genetic variation and to identify evolutionarily distinct lineages for conservation action. The distribution of Philippine tarsier genetic diversity is neither congruent with expectations based on biogeographical patterns documented in other Philippine vertebrates, nor does it agree with the most recent Philippine tarsier taxonomic arrangement. We identify three principal evolutionary lineages that do not correspond to the currently recognized subspecies, highlight the discovery of a novel cryptic and range-restricted subcenter of genetic variation in an unanticipated part of the archipelago, and identify additional geographically structured genetic variation that should be the focus of future studies and conservation action. Conservation of this flagship species necessitates establishment of protected areas and targeted conservation programs within the range of each genetically distinct variant of the Philippine tarsier.     

Importance of scale in nest-site selection by Arizona gray squirrels

Nests provide a place for individuals to rest, raise young, avoid predators, and escape inclement weather; consequently, knowledge of habitat characteristics important to nest placement is critical for managing species of conservation concern. Arizona gray squirrels (Sciurus arizonensis) are endemic to mountains of southwestern United States and northwestern Mexico. We investigated factors influencing nest-site selection at 4 spatial scales (forest-type, nest-site, nest-tree, and within-canopy placement) to provide ecological information and management recommendations for this sensitive species. Nest densities were 2.6 times higher in riparian than pine-oak woodlands. Nest sites had more large trees, snags, logs, and canopy cover and had lower slope. Arizona gray squirrels selected tall trees with more interlocking trees and tended to place nests adjacent to the main trunk. Regardless of scale, Arizona gray squirrels seemed to select nesting areas for their ability to provide protection from predators and the elements as well as access to food. Consequently, maintaining large trees with closed canopies and downed logs should be considered when determining land management plans. © 2011 The Wildlife Society.     

Trait-dependent declines of species following conversion of rain forest to oil palm plantations

Conversion of natural habitats to agriculture reduces species richness, particularly in highly diverse tropical regions, but its effects on species composition are less well-studied. The conversion of rain forest to oil palm is of particular conservation concern globally, and we examined how it affects the abundance of birds, beetles, and ants according to their local population size, body size, geographical range size, and feeding guild or trophic position. We re-analysed data from six published studies representing 487 species/genera to assess the relative importance of these traits in explaining changes in abundance following forest conversion. We found consistent patterns across all three taxa, with large-bodied, abundant forest species from higher trophic levels, declining most in abundance following conversion of forest to oil palm. Best-fitting models explained 39–66 % of the variation in abundance changes for the three taxa, and included all ecological traits that we considered. Across the three taxa, those few species found in oil palm tended to be small-bodied species, from lower trophic levels, that had low local abundances in forest. These species were often hyper-abundant in oil palm plantations. These results provide empirical evidence of consistent responses to land-use change among taxonomic groups in relation to ecological traits.     

Bird Response to Prescribed Silvicultural Treatments in Bottomland Hardwood Forests

ABSTRACT Silvicultural treatments prescribed to enhance wildlife habitat by promoting structural heterogeneity via retention of large live trees, snags, and coarse woody debris has been termed wildlife-forestry. Wildlife-forestry has been advocated for management of bottomland hardwood forests on public conservation lands within the Mississippi Alluvial Valley, USA. On Tensas River National Wildlife Refuge in northeast Louisiana, we used distance sampling during 6 visits to 138 point locations to estimate avian densities within stands subjected to variable-retention harvests, within a 13-year chronosequence, and untreated control stands. Densities of 9 species, including 6 species of conservation concern, were greater in treated stands than on untreated stands. Five species responded negatively to treatments and had greater densities in untreated control stands. Based on conservation concern scores established by Partners in Flight and annual detections of each of 30 species, treated stands afforded greater community-wide bird conservation than did untreated stands. For most species, maximum treatment response was between 5 years and 8 years posttreatment with duration of treatment effect <13 years. Therefore, habitat conditions on treated stands should be reevaluated at circa 15-year intervals and, if warranted, additional silvicultural treatment prescribed to rejuvenate habitat conditions.     

The conservation physiology of seed dispersal

At a time when plant species are experiencing increasing challenges from climate change, land-use change, harvesting and invasive species, dispersal has become a very important aspect of plant conservation. Seed dispersal by animals is particularly important because some animals disperse seeds to suitable sites in a directed fashion. Our review has two aims: (i) to highlight the various ways plant dispersal by animals can be affected by current anthropogenic change and (ii) to show the important role of plant and (particularly) animal physiology in shaping seed-dispersal interactions. We argue that large-bodied seed dispersers may be particularly important for plant conservation because seed dispersal of large-seeded plants is often more specialized and because large-bodied animals are targeted by human exploitation and have smaller population sizes. We further argue that more specialized seed-dispersal systems on island ecosystems might be particularly at risk from climate change both owing to small population sizes involved but also owing to the likely thermal specialization, particularly on tropical islands. More generally, the inherent vulnerability of seed-dispersal mutualisms to disruption driven by environmental change (as well as their ubiquity) demands that we continue to improve our understanding of their conservation physiology.
