More than garden plants: extending the conversation of urban gardens as an important refuge for Australian birds

Abstract Inadequacies in public protected area networks dictates that private land will play an important role in the conservation of biodiversity in the coming decades. Household gardens are a key example of private lands that can serve as refuges for biodiversity, with birds as a popular flagship for garden biodiversity. Discussion has focused heavily on the species of plant a resident might select to attract birds to their garden. In this paper, we describe additional and important factors that should form part of this broader conversation on gardens for birds and biodiversity, with a specific aim of drawing attention to species that are at risk of localised extinctions in modern urban landscapes – urban adaptors. We present our commentary in two themes: (a) mitigating threats to birds in the urban environment and (b) enhancing the habitat value of the urban environment for a broader range of bird species. We provide a synthesis of the research of recent years that has explored the urban environment and its ability to support birds, but importantly, we extend on this by bringing together topics that have been somewhat lacking in the discussion to date. In a new approach to this conversation, this paper brings together key topics that can no longer be considered in isolation if we are to make significant conservation gains in the environments were most Australians now reside.

Conservation threats from tourism land grabs and greenwash

We report a new threat to conservation, namely land grabs by large tourism developers inside public protected areas. Locally, these tourism land grabs damage national parks through building footprints and access corridors, bringing habitat fragmentation, noise, light, roadkill, fire risk, and invasive plant and animal species and pathogens. They also create negative impacts on social equity and regional economies. The global tourism industry now perceives private development in public national parks as a mechanism to profit from land speculation, rather than merely monopoly provision of visitor services. Investment funds now use tourism, often with socialwashing components, as a political lever for land grabs. International “nature positive” marketing by tourism industry associations and multilateral tourism advocacy organisations is greenwash: it lacks substance, and aims to coopt conservation organisations.

Analysis of the Decisive Factors of Government Attracting Tourists in Public Management from the Perspective of Environmental Protection

Tourism is a critical sustainable social and economic activity that can empower local communities. The current study strived to explore decisive factors that might be used it promotes environmental protection. Governments worldwide might employ to improve conservation and the tourism sector. There is a need to sponsor more publications on tourism and the environment that provide rigor, insight, and significance. There is also a need to address critical impacts, including greenhouse gases for airlines, liquid wastes for cruise ships, water and energy conservation for urban hotels, vegetation clearance, and wildlife displacement for rural resorts, and a range of direct and indirect local impacts on plants and animals for nature-based and adventure tourism in parks and wilderness areas. Governments need to work on economic models that address; currency exchange rates; airfares and taxes; land tenure and wildlife ownership laws; transport infrastructure; police, quarantine, and border security; investment law; public protected-area systems; and a variety of social pressures and fashions. The most effective means to improve environmental management in tourism is through laws and regulations for development planning, pollution control, and protected areas. In developed nations, tourism threatens conservation as property developers push to build private facilities inside public protected areas. In developing nations, tourism is a tool to fund conservation in public parks and private or communal lands. Visitors to the public, and protected areas contribute political and financial capital to park agencies. A few private tourism operators have converted areas of private and communal land to conservation.

Tourism and Environment: Ecology, Management, Economics, Climate, Health, and Politics

We review research on tourism and the environment using a temporal framework, distinct from previous reviews. We identify six main phases, all still active, but with different histories. Initially, tourism was treated as a low-impact component of transport and urban accommodation, and the focus was on recreation, ecology and visitor management in parks. Interest then turned to environmental management and corporate social responsibility: wastes, resources, and ecolabels. The third phase analysed positive economic contributions to conservation by a small number of tourism enterprises, principally through private reserves and park funding. The fourth focussed on climate change and carbon offsets, and the fifth on mental health and human capital. The sixth and newest phase is political. Tourism developers, industry associations, and lobbyists have stepped up their longstanding efforts to gain control of parks and protected areas, in order to profit from preferential access to public resources. These efforts now include international instruments as well as policies, practices, and legislation in individual countries. Tourism has become a catspaw for a new form of land grab by private wealth portfolios for high-value nature property. We draw attention to tourism development land grabs in public protected areas as a key priority for urgent research.

Determinants and costs of strategic enrollment of landowners in a payments for ecosystem services program in a deforestation hotspot: The Argentine Chaco forest

Understanding landowners’ decisions about how much land to enroll in payments for ecosystem services (PES) programs is essential to strategically target lands for conservation, prevent forest fragmentation, and thus maintain ecosystem services. In this study, we targeted private lands surrounding and connecting public protected areas in a deforestation hotspot, the Argentine Chaco forest. We used alternatively configured PES contracts in choice experiments to understand landowners’ decisions regarding how much land to enroll in PES. We found that factors influencing decisions on how much land to enroll differ from those influencing willingness to participate in PES. The percentage of their property that landowners were willing to enroll in the program increased with higher payments and permitted land use that closely aligned with traditional land use, specifically cattle ranching under tree canopy. Contract length was important in willingness to enroll but not in amount of land enrolled. Payments required to enroll all land in our study area, and thus conserve an unfragmented landscape, exceeded the financial resources of the Argentine PES program. Designing PES to enroll private lands on smaller strategic areas, in conjunction with other conservation initiatives, would be more effective than attempting to use PES alone to conserve large landscapes.

Assessing the ecosystem services and disservices provided by migratory wildlife across the Greater Yellowstone Ecosystem

Highly mobile and migratory wildlife are ecologically, culturally, and economically important because they provide ecosystem services across heterogenous landscapes. Migratory ungulates (hoofed mammals) are particularly influential because of their large body size, seasonal movement across vast distances, and ties to human society. Ungulate migrations are widely declining in the face of habitat alteration, and initiatives across the globe seek to conserve them. However, migratory herds can generate significant costs or disservices for landowners and communities, complicating management and conservation. We demonstrate how a comprehensive assessment of the ecosystem services and disservices (ESDs) provided by mobile wildlife can enable conservation policy that facilitates co-existence across multi-use landscapes. Our mixed-methods approach applies the widely recognized Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) ESD categories as a framework to combine formal scientific knowledge spanning multiple disciplines with experiential knowledge gathered from local stakeholders through interviews. We apply this methodology in the context of the Greater Yellowstone Ecosystem (GYE), which harbors long-distance migrations of six ungulate species that move between public protected areas and private working lands. We discuss how stakeholder knowledge corroborates or contradicts scientific literature and characterize stakeholder groups and their perspectives. We suggest that formal assessments of ESDs within their ecological and socioeconomic contexts could mobilize resources for conservation, increase returns on conservation spending, and support conflict resolution amongst groups seeking to manage wildlife for different objectives.

Evaluation of the Impact of Policymakers’ Decisions in the Management Capacity of Protected Areas: Efficiency Evidence from Five Countries

Protected areas play an important role in biodiversity conservation and tourism. Significant efforts have been made to increase the amount of protected lands. A problem of increasing the amount of public protected areas is that governments and other institutions face difficulties in providing the necessary resources for effective management. Accordingly, managers must be as efficient as possible but the lack of comparative methods makes the evaluation of efficiency difficult. Using Data Envelopment Analysis, a non-stochastic and non-parametric approach, information from 29 protected areas in 5 countries was analyzed to compare management efficiency amongst them. The first result found is the level of management efficiency that each park has in comparison with the others parks. The other important result is a prediction of the changes in the outputs if there is a hypothetical budget change. These results allow the generation of information for decision making.

Lessons from COVID-19 for wildlife ranching in a changing world

The COVID-19 pandemic provided an opportunity to assess the impacts of a global disturbance on conservation land uses and learn from responses to the crisis to enable more resilient conservation systems. To understand socio-economic responses of diverse wildlife working lands to COVID-19, we surveyed owners and managers of 78 private wildlife ranches (wildlife working lands), 23 agricultural farms (conventional working lands) and six public protected areas (conventional conservation lands) in South Africa. Most protected areas lost more than 75% of their revenues during 2020, while most agricultural farms lost less than 10%. The impact on wildlife ranches was more varied. Ranches with more diverse activities, particularly mixed wildlife–agriculture systems, lost less revenue, shifting their activities from those heavily impacted (international ecotourism, trophy hunting) to those less affected (for example, wildlife meat, livestock). This adaptive capacity suggests that wildlife-based enterprises could represent key ecosystem-based adaptations, providing lessons for integrated global policies that seek to incorporate private land models in the 2030 Biodiversity Framework. Conservation efforts were impacted in varied ways by the COVID-19 pandemic. This study assessed how South African wildlife ranches, agricultural farms and protected areas weathered the pandemic, finding greater adaptive capacity among more diversified and mixed business models.

Plant, bird, and mammal diversity of the Tomogrande field station, Vichada, Colombia

The Altillanura is a unique ecosystem within the Colombian Llanos, characterized by well-drained savannas and extensive riparian forests. The Altillanura harbors a rich assemblage of species, largely understudied and currently under threat by large-scale and unplanned agribusiness. Moreover, the number of public protected areas in the Colombian Llanos, particularly in the Altillanura, is insufficient to conserve the threatened habitats and species. Therefore, conservation efforts by private reserves are crucial for the protection of the region’s biodiversity. Here we present the first species list of the Tomogrande, a private nature reserve and scientific research field station in the municipality of Santa Rosalía, Vichada, Colombia. After ten years of ongoing research, we have recorded 299 species of plants, 189 species of birds, and 47 species of mammals. Compared to other private nature reserves in Vichada and the Tuparro National Park, the largest protected area in the region, Tomogrande makes a substantial contribution to the conservation of all three taxonomic groups. We advocate that better landscape planning and sustainable practices should become mandatory in the Altillanura to protect its biodiversity and the livelihoods of all stakeholders that inhabit this region.

The Role of Government in a Partial Transition from Public to Private in the Expanding Australian Protected Area System

Since the 1980s in democratic societies, neoliberal reforms and neofeudal governance have transferred the delivery of many public goods and services from governments to non-government actors. Privatisation is a core neoliberal agenda, but little is known of the nature and extent of its application to nature conservation through reservation. We investigate the degree of privatisation of the expanding protected area system in our case study areas of Australia and Tasmania, hypothesising that governments have: disrupted public agencies managing the protected area estate by repeated reorganisation; diverted public funds from public to private protected areas; and increasingly alienated public reserves for subsidised private profit from tourism. We found frequent restructuring of agencies managing protected areas. Although Federal Government expenditure on private reserves increased markedly in the twenty-first century, so did expenditure on public conservation reserves. All States except Queensland increased public protected area funding. Direct subsidisation of private reserves by government has not had a steady upward trajectory. In contrast, subsidisation of private alienation of public conservation reserves for tourism may have accelerated in the twenty-first century. We conclude that, while Australian governments see value in protected areas as a source of economic development and electoral advantage, they are agnostic on ownership.

THE MUNICIPALITY’S STUDY AS A DIRECTIONAL PLAN FOR SPATIAL DEVELOPMENT

The municipality’s study should be a legal act of an internal nature, binding the units subordinate to the commune council and the head of the commune within the scope of the undertaken investments and protection activities in the land. The study should define, first of all, the location of public investments, protected areas and zones, as well as the type of permissible development, binding when drawing up local plans and any other legal acts, both internal and generally applicable, determining the conditions for using the land. Thus, the study would become a plan to control spatial development.

Private reserves suffer from the same location biases of public protected areas

Setting aside private land is an essential component of the biodiversity crisis response. In Brazil, landowners are required to have Legal Reserves (LR) (20%–80% of their property set aside for native vegetation) which, if degraded, need to be restored. Alternatively, landowners can compensate for an LR deficit by purchasing surplus credits. Each landowner can define the location and spatial arrangement of their LR, affecting the reserve's ability to maintain biodiversity and provide ecosystem services (ES). We used hierarchical models to determine drivers for the amount and location of those LR in 3622 farms. The likelihood of setting aside part of the farm as LR (avoiding off-farm compensation) increased with farm size and extent of native vegetation cover, particularly for riparian areas and steep slopes, where conserving vegetation is also mandated in what are called Areas of Permanent Protection (APP). Properties with APP were more likely to meet the full LR requirement within their areas if located in areas of higher transportation costs and lower agricultural suitability. Within properties, the location of LR was mostly in areas with low agricultural suitability, high transportation cost, and close to APP. Landowners' decisions intend to maximize property income and reduce restoration costs, resulting in a spatial pattern similar to public protected areas — usually located on marginal land for agriculture. These areas do not necessarily provide the greatest biodiversity and ES benefits, suggesting that government interventions may be needed to encourage landowners to set aside native vegetation in ways that maximize conservation and ES outcomes.

Success in conserving the bird diversity in tropical forests through private protected areas in Western Ecuador

Private protected areas have recently attained more importance at a worldwide level as regards nature conservation. Particularly, the specific region of Western Ecuador receives hardly any protection from the State, and private reserves could, therefore, be a suitable tool to ensure the preservation of its forests and their associated wildlife biodiversity. In this work, we compare the bird species richness between private reserves and public protected areas (managed by the State) located in this region. We also show a checklist of bird species found in the Buenaventura Reserve, a private reserve located in south-western Ecuador. Our comparison shows that smaller private reserves may harbour a similar number of bird species than larger protected areas managed by the state, and they have a higher number of bird species per area. In particular, a total of 233 different bird species were registered in Buenaventura, which were distributed in 16 orders and 42 families. Three species were classified as endangered at an international level: El Oro Parakeet (Pyrrhura orcesi), El Oro Tapaculo (Scytalopus robbinsi), and the Grey-backed Hawk (Pseudastur occidentalis), and another three at a national level: the Long-wattled Umbrellabird (Cephalopterus penduliger), the Slaty-winged Foliage-gleaner (Philydor fuscipenne), and the White-vented Plumeleteer (Chalybura buffonii). Therefore, private reserves can be appreciated as a suitable conservation tool for bird conservation, and they should not be undervalued because of their smaller size. Buenaventura Reserve is a good example of how private reserves are extremely important in fragmented landscapes, as is the case with tropical forests in Western Ecuador.

No bats, no gain: educational intervention increases farmers perception of ecosystem services

ABSTRACT Brazil’s network of public Protected Areas (PAs) occupy 28.9% of its territory, and large remnants of native vegetation are also found on private lands, therefore landowners play central roles in any conservation debate: they are required to protect native vegetation on their lands and are neighbours of PAs. In this study, we tested the hypothesis that an educational activity focused on ecosystem services (ESs) and the ecological processes underpinning them could improve landowners’ perception of public and private PAs. We designed a classic experiment by applying a pretest and posttest to control and intervention groups. The intervention was a workshop for Brazilian landowners to educate them about a public PA and to demonstrate how ESs provided by native areas positively impact rural activities. We used a questionnaire and a series of images to conduct face-to-face interviews. Our results revealed that landowners who participated in the workshop identified more activities developed in the public PA, were more aware of pollination, and recognized more ESs during the interviews. Conservation initiatives should promote educational events for landowners. In particular, practical activities and demonstrations involving emblematic species help rural people to understand the links between native biodiversity, ESs and well-being.

Understanding landowners’ intention to restore native areas: The role of ecosystem services

Understanding landowners’ intention to voluntarily engage in conservation initiatives is essential to designing more realistic projects and interventions. In this study, we used the Theory of Planned Behavior to identify the psychological constructs underlying landowners’ intention to restore areas with native vegetation on their properties over the next three years. We extended the model, investigating whether the perception of ecosystem services, age, number of springs, and size of property affect the intention studied. We interviewed 75 landowners whose properties are in the surroundings of a public protected area in Brazil and applied structural equation modeling to analyze the acquired data. The results agree with the predicted relationship between attitudes and intention. Furthermore, perception of the ecosystem services and the number of springs on a given property are two factors which directly affect attitude and indirectly affect the intention to restore. Younger landowners are more willing to restore. These results suggest that understanding the benefits of conserving biodiversity on farmland affects management practices. Investing in educational initiatives to promote more knowledge about ecosystem services will increase the involvement of more landowners in future conservation programs.

Impacts of Riparian Restoration on Vegetation and Avifauna on Private and Communal Lands in Northwest Mexico and Implications for Future Efforts

Restoring and enhancing riparian vegetation on private and communal lands in Mexico is important for biodiversity conservation given the ecological significance of these areas and the scarcity of public protected areas. To enhance riparian vegetation and wildlife habitats and train local people in restoration techniques, we implemented restoration and outreach efforts on private and communal lands in the Sky Islands region of northwest Mexico. We fenced 475 ha of riparian zones from livestock, erected erosion-control structures, planted trees, and developed management agreements for cool-season grazing with landowners on 10 ranches across 3 sites in 2012-2013, then repaired fences and renegotiated agreements in 2017-2019. To foster evaluation, we used a before-after/control-impact design to measure attributes of vegetation structure and bird communities and compared baselines from 2012 with post-treatment estimates from 2019. As predicted, understory vegetation volume generally increased in treatments relative to controls ( P = .09), especially when one treatment area with the lowest pre-treatment grazing impacts was censored ( P = .01). Although canopy cover also increased, there was little differential change in treatments relative to controls ( P ⩾ .23) due likely to longer time periods needed to realize responses. Densities of most focal bird populations varied across time periods in directions that typically matched observed changes in vegetation structure, but fewer species showed signs of differential positive change linked to treatments relative to controls. Densities of Yellow-breasted Chat, a key understory obligate and important focal species, increased in treatments relative to controls across sites, as did densities of Sinaloa Wren, which also use dense underbrush ( P ⩽ .05). Positive changes by other understory obligates (eg, Common Yellowthroat, Song Sparrow) were more local but sometimes of high magnitude (>8-fold) also suggesting positive impacts of treatments. Despite mixed results over a limited time period, these patterns suggest restoration efforts drove localized recovery of understory vegetation and associated bird populations, but benefits varied widely with environmental and social factors linked to management. Greater ecological benefits to riparian areas on private and communal lands in this region can be fostered by further incentivizing construction, maintenance, and proper use of restoration infrastructure, through education, and by building relationships based on trust and credibility with landowners.

What do outdoor recreationists think of fracking? Politics, ideology, and perceptions of shale gas energy development in Pennsylvania State Forests

This study examined the influence of political ideology and perceptions of benefits and risks upon State Forest recreationists’ support and opposition towards shale natural gas energy development (SGD) on public and private lands in Pennsylvania. Much of the ongoing and proposed Pennsylvania SGD infrastructure is either within or adjacent to public lands, waters, and protected areas, raising concerns about the potential environmental and social impacts upon recreation stakeholders. On-site face-to-face survey interviews were used to gather data from Pennsylvania State Forest recreationists from June to September of 2018 (n = 392). The predominantly local, educated, experienced, and politically moderate sample in this study demonstrated relatively low levels of support towards SGD on Pennsylvania public lands and relatively neutral stances towards support for SGD on private lands in Pennsylvania. Structural equation modeling results suggested that political ideology and perceptions of risks were significant predictors of support for SGD on both public and private lands in Pennsylvania. The relationship between political ideology and support for SGD on public and private lands was also partially mediated through the perceived risk of SGD in the model. Study findings contributed to previous research suggesting political attitudes may influence and supersede other factors when predicting support for SGD. A series of one-way analyses of variance further explored differences by political ideology in this study. In each of these analyses, a similar statistical trend prevailed. Those identifying themselves as conservative were significantly more likely than their moderate and liberal counterparts to support SGD on both public and private lands in Pennsylvania and perceive fewer risks from SGD on Pennsylvania State Forests. This research lent itself to the theory of landscape fit and construal level theory as State Forest recreationists may have perceived the ‘fit’ of SGD negatively and could have construed SGD abstractly, lending themselves to political ideology. From a policy and management standpoint, study findings highlight the importance of assessing and communicating State Forest recreationists’ perceptions and subsequent opinions when planning, developing, and managing SGD and related decisions in the United States.

Economic Valuation of Conservation of Inholdings in Protected Areas for the Institution of Payments for Ecosystem Services

Ecosystem services, as public goods, are often undersupplied because private markets do not fully take into account the social cost of production. To alleviate the concern about this imbalance situation, payments for ecosystem services (PES) have emerged as a preferable alternative. While temples in Korea have owned a considerable part of the national parks, a PES approach can be used as a viable option to alleviate the conflicts among visitors, non-visitors, and temples. The purpose of this paper is to assess the economic values of ecosystem services provided by temple forests as a compensation mechanism. Using a contingent valuation method, an online survey was conducted with 1000 respondents. Study results showed that the economic benefits of the conservation of temple forests were estimated to be substantial, ranging from ₩5980 (US $5.42) to ₩7709 ($7.08) per household per year. The results also confirmed the effects of social factors such as individuals’ trust in the government’s environmental policies and importance on the conservation of temples’ cultural and religious values on the willingness to pay. With a growing interest in securing ecosystem services through a PES approach, estimating economic benefits of the conservation of inholdings in public protected areas will be a valuable piece of information as an important policy decision-making tool.

Living on the edge: Forest cover threshold effect on endangered maned sloth occurrence in Atlantic Forest

Habitat loss and the isolation of remaining habitats are undoubtedly the two greatest threats to biodiversity conservation, especially for the maned sloth, due to its ecological restrictions. In this study, we identified a critical threshold of forest cover for maned sloth occurrence and explored the effects of other local and landscape variables. We sampled 68 sites, where we searched for the maned sloth and collected local habitat variables. We calculated the percentage of forest cover and open areas, assessing the appropriated scale through model selection. We used occupancy models and model selection methods to identify the threshold and assess occupancy and detection probabilities. The occupancy probability of the maned sloth is 0.97, but it decreases abruptly at 35% of forest cover, reaching zero in areas with less than 20% of forest cover. The two landscape variables are the most important predictors of sloth occupancy, based on the cumulative weight of evidence, were: Forest cover (78%) and Open areas cover (46%); the latter influencing negatively maned sloth occupancy. This is the first attempt to identify the habitat requirements of the threatened maned sloth in a fragmented area using landscape and local variables. Our results imply that conservation of maned sloth will benefit from an increase in the amount of native forest at the landscape scale. Given difficulties in the creation of new public protected areas, this improvement could be achieved via the recovery of areas located in private properties that are protected by the Brazilian Forest Code.
