Trooping fairies,trolls, and talking tigers: the influence of traditional wilderness archetypes on current land use patterns

Broadly defined, “wilderness” encompasses all areas outside the cultural sphere, i.e., not under direct, intensive, and purposeful human control and maintenance. Because of the perceived dangers of wilderness, people are unlikely to settle deeply in wild areas, especially in their archetypical wilderness. Topographically-defined wilderness archetypes (e.g., mountains) are likely more resistant to development than the more easily obliterated land cover-defined wilderness archetypes (e.g., forests), which should lead to divergent landscape patterns. Fairytales and the names of protected areas from Ireland, Germany, and Korea were examined for evidence of wilderness archetypes. Germany and Korea (but not Ireland) exhibited archetypes (forest and mountain, respectively). The land use patterns with respect to ruggedness and relative elevation in Germany and Korea were compared with predictions based on archetype. Korea had a significantly more conservative and stricter decision rule with regards to development in rugged areas and more predictable elevational transitions from civilization to wilderness, consistent with a reluctance to develop a mountain wilderness archetype. Korean cities had similar patterns to all of Korea, while non-East Asian cities hemmed in by mountains (Germany has none) were variable but similar to Germany, implying that the observed differences are cultural not agricultural. These results indicate the important, but largely unrecognized, influence cultural details have on land use patterns and by extension conservation challenges, opportunities, and priorities. Specifically, wilderness archetypes are likely overrepresented in protected and undeveloped areas. Furthermore, wilderness archetype communities (particularly those topographically defined) likely experience less fragmentation, more restricted development, and less drastic anthropogenic disturbance.     

Wilderness and future conservation priorities in Australia

Aim Most approaches to conservation prioritization are focused on biodiversity features that are already threatened. While this is necessary in the face of accelerating anthropogenic threats, there have been calls to conserve large intact landscapes, often termed ‘wilderness’, to ensure the long‐term persistence of biodiversity. In this study, we examine the consequences of directing conservation expenditure using a threat‐based framework for wilderness conservation. Location The Australian continent. Methods We measured the degree of congruence between the extent of wilderness and the Australian protected area network in 2000 and 2006, which was established using a threat‐based systematic planning framework. We also assessed priority areas for future reserve acquisitions identified by the Australian government under the current framework. Results In 2000, 14% of Australia’s wilderness was under formal protection, while the protected area network covered only 8.5% of the continent, suggesting a historical bias towards wilderness protection. However, the expansion of the reserve system from 2000 to 2006 was biased towards non‐wilderness areas. Moreover, 90% of the wilderness that was protected over this period comprised areas not primarily designated for biodiversity conservation. We found a significant (P < 0.05) negative relationship between bioregions considered to be a priority for future reserve prioritization and the amount of wilderness they contain. Main conclusions While there is an urgent need to overcome past biases in reserve network design so as to better protect poorly represented species and habitats, prioritization approaches should not become so reactive as to ignore the role that large, intact landscapes play in conserving biodiversity, especially in a time of human‐induced climate change. This can be achieved by using current or future threats rather than past threats to prioritize areas, and by incorporating key ecological processes and costs of acquisition and management within the planning framework.     

The Wilderness Act and Fish Stocking: An Overview of Legislation, Judicial Interpretation, and Agency Implementation

Many high-elevation lakes in designated wilderness are stocked with native and nonnative fish by state fish and game agencies to provide recreational fishing opportunities. In several areas, this practice has become controversial with state wildlife managers who support historical recreational use of wilderness, federal wilderness managers who assert that stocking compromises some of the ecological and social values of wilderness, and different public groups that support one or the other position. Herein we examine this controversy from the perspective of the 1964 Wilderness Act, its judicial interpretation, the policies of the federal agencies, and formal agreements between federal and state agencies. Although some state stocking programs restore native fish populations, other programs may compromise some of the ecological and social values of wilderness areas. Further, although current federal regulations recognize state authority for fish stocking, judicial interpretation gives federal agencies the authority for direct involvement in decisions regarding fish stocking in wilderness. Where there are differences of opinion between state and federal managers, this judicial interpretation strongly points to the need for improved cooperation, communication, and coordination between state wildlife managers and federal wilderness managers to balance recreational fishing opportunities and other wildlife management activities with wilderness values.

Wilderness Restoration: The Paradox of Public Participation

Recent trends in ecological restoration complicate the job of wilderness managers. An emphasis on volunteer participation in restoration designed to foster human/nature relationships often conflicts with the mandate to leave land untrammeled. We frame this conflict as the “participation paradox.” Higgs’ (2003) Nature by Design contains a response to the paradox that includes a strong defense of participatory focal restoration and a related critique of wilderness. After identifying the limitations of Higgs’ arguments, we address the paradox by showing how an appeal to the moral virtues of humility, self‐restraint, and altruism supports a restrictive conception of wilderness and a healing metaphor for wilderness restoration. The virtue‐informed healing metaphor provides an argument for restricting volunteer participation and long‐term restoration projects in wilderness areas. It also identifies the general conditions in which damaged wilderness should be allowed to “heal itself.” The upshot of our approach to the paradox is that some standards for good restoration should be contextualized to land use designations. In particular, the emphasis on participatory restoration is appropriate in humanized landscapes but not in wilderness.     

Roadless wilderness area determines forest elephant movements in the Congo Basin

A dramatic expansion of road building is underway in the Congo Basin fuelled by private enterprise, international aid, and government aspirations. Among the great wilderness areas on earth, the Congo Basin is outstanding for its high biodiversity, particularly mobile megafauna including forest elephants (Loxodonta africana cyclotis). The abundance of many mammal species in the Basin increases with distance from roads due to hunting pressure, but the impacts of road proliferation on the movements of individuals are unknown. We investigated the ranging behaviour of forest elephants in relation to roads and roadless wilderness by fitting GPS telemetry collars onto a sample of 28 forest elephants living in six priority conservation areas. We show that the size of roadless wilderness is a strong determinant of home range size in this species. Though our study sites included the largest wilderness areas in central African forests, none of 4 home range metrics we calculated, including core area, tended toward an asymptote with increasing wilderness size, suggesting that uninhibited ranging in forest elephants no longer exists. Furthermore we show that roads outside protected areas which are not protected from hunting are a formidable barrier to movement while roads inside protected areas are not. Only 1 elephant from our sample crossed an unprotected road. During crossings her mean speed increased 14-fold compared to normal movements. Forest elephants are increasingly confined and constrained by roads across the Congo Basin which is reducing effective habitat availability and isolating populations, significantly threatening long term conservation efforts. If the current road development trajectory continues, forest wildernesses and the forest elephants they contain will collapse.     

基于人类活动视角的中国陆域荒野地评估方法

随着人类活动逐渐增加,自然生境向人工基质的转换已成为全球野生动物生存的严重威胁,准确识别荒野地的空间范围对生态治理和生物多样性保护具有重要意义。当前,利用较高精度的新型数据,考虑区域尺度上的地理特征构建指标模型,并识别国家尺度荒野地的实践还较少。从人类活动对自然影响的视角出发构建荒野地识别模型,首先考虑微观视角下人类活动对复杂地理环境的响应特征,构建多要素综合的人类非持续性活动强度计算模型;引入新型数据源,构建空间特征提取算法并建立人工环境和光污染影响指标,明确人类长期活动区;刻画可能的荒野地空间范围,并定量评价其荒野程度。对中国陆域荒野地的识别结果表明:(1)基于人类活动视角构建的荒野地识别模型可有效模拟中国陆域范围内的荒野度分布,其大致呈现"西高东低"的空间格局;(2)中国荒野地占中国陆域面积的22.47%,主要分布在大小兴安岭、青藏高原、内蒙古高原、塔里木盆地等地区;(3)结果与基于人类足迹法的荒野地数据对比,重合率超过80%,表现出良好的识别能力,且为部分区域提供了具有参考性的识别结果。     

Some of the rarest European saproxylic beetles are common in the wilderness of Northern Mongolia

Natural landscapes characterized by heavy disturbance regimes were displaced in Europe by managed cultural landscapes over the past centuries. The associated loss of biological legacies, such as dead or dying trees, has exposed numerous saproxylic species to high risks of extinction. In contrast, extensive wilderness forests in Northern Mongolia have been sustained owing to significant cultural differences. Here we used saproxylic beetle abundance data gathered during two sampling campaigns in the Mongolian taiga to address whether (1) the saproxylic beetle fauna of the Mongolian taiga is comparable to that of European boreal forests, (2) fires are a natural disturbance regime, indicated by the occurrence of many pyrophilous species, and (3) species rare in Europe are also rare in the Northern Mongolian wilderness. Of 191 saproxylic beetle species identified, 150 (79 %) were also found in Europe. The high number of pyrophilous beetle species (20) indicated that natural species communities are well adapted to this disturbance regime. The species rarity in Germany was significantly positively correlated with the species rarity in Finland, but the species rarity in these two countries was negatively correlated with that in the Mongolian wilderness. Our results indicated that wilderness areas with natural disturbances provide biological legacies important for rare species. Therefore, exploitation of the unique, remaining natural landscapes of the Palaearctic wilderness areas should be stopped. Moreover, we urge conservationists to expand controlled burning for restoration at relict sites of rare boreal species also outside Fennoscandia.     

Renewable energy development threatens many globally important biodiversity areas

Transitioning from fossil fuels to renewable energy is fundamental for halting anthropogenic climate change. However, renewable energy facilities can be land‐use intensive and impact conservation areas, and little attention has been given to whether the aggregated effect of energy transitions poses a substantial threat to global biodiversity. Here, we assess the extent of current and likely future renewable energy infrastructure associated with onshore wind, hydropower and solar photovoltaic generation, within three important conservation areas: protected areas (PAs), Key Biodiversity Areas (KBAs) and Earth's remaining wilderness. We identified 2,206 fully operational renewable energy facilities within the boundaries of these conservation areas, with another 922 facilities under development. Combined, these facilities span and are degrading 886 PAs, 749 KBAs and 40 distinct wilderness areas. Two trends are particularly concerning. First, while the majority of historical overlap occurs in Western Europe, the renewable electricity facilities under development increasingly overlap with conservation areas in Southeast Asia, a globally important region for biodiversity. Second, this next wave of renewable energy infrastructure represents a ~30% increase in the number of PAs and KBAs impacted and could increase the number of compromised wilderness areas by ~60%. If the world continues to rapidly transition towards renewable energy these areas will face increasing pressure to allow infrastructure expansion. Coordinated planning of renewable energy expansion and biodiversity conservation is essential to avoid conflicts that compromise their respective objectives.     

Vulnerability of ecosystems to climate change moderated by habitat intactness

The combined effects of climate change and habitat loss represent a major threat to species and ecosystems around the world. Here, we analyse the vulnerability of ecosystems to climate change based on current levels of habitat intactness and vulnerability to biome shifts, using multiple measures of habitat intactness at two spatial scales. We show that the global extent of refugia depends highly on the definition of habitat intactness and spatial scale of the analysis of intactness. Globally, 28% of terrestrial vegetated area can be considered refugia if all natural vegetated land cover is considered. This, however, drops to 17% if only areas that are at least 50% wilderness at a scale of 48 × 48 km are considered and to 10% if only areas that are at least 50% wilderness at a scale of 4.8 × 4.8 km are considered. Our results suggest that, in regions where relatively large, intact wilderness areas remain (e.g. Africa, Australia, boreal regions, South America), conservation of the remaining large‐scale refugia is the priority. In human‐dominated landscapes, (e.g. most of Europe, much of North America and Southeast Asia), focusing on finer scale refugia is a priority because large‐scale wilderness refugia simply no longer exist. Action to conserve such refugia is particularly urgent since only 1 to 2% of global terrestrial vegetated area is classified as refugia and at least 50% covered by the global protected area network.     

Occupancy Patterns in a Reintroduced Fisher Population during Reestablishment

Monitoring population performance in the years following species reintroductions is key to assessing population restoration success and evaluating assumptions made in planning species restoration programs. From 2008–2010 we translocated 90 fishers (Pekania pennanti) from British Columbia, Canada, to Washington's Olympic Peninsula, USA, providing the opportunity to evaluate modeling assumptions used to identify the most suitable reintroduction areas in Washington and enhance understanding of fisher habitat associations in the late-successional forest ecosystems in the coastal Pacific Northwest. From 2013–2016, we deployed 788 motion-sensing cameras and hair (DNA)-snaring devices distributed among 263 24-km² primary sampling units across the Olympic Peninsula. Our objectives were to determine whether occupancy patterns of the reestablishing population supported assumptions of the initial habitat assessment models, whether the population had expanded or shifted in distribution since the initial reintroductions, compare physical habitat attributes among land-management designations, and determine whether the founding fishers had successfully reproduced. We predicted that site occupancy by fishers would be associated with landscapes characterized by high proportional coverage of dense forest canopies and medium-sized and large trees, a diversity of stand structural classes, and area near the administrative boundary separating wilderness from more intensively managed forest lands. We detected fishers across designated wilderness, federal lands outside of wilderness, and other land designations in proportion to land availability on the Peninsula. We found negligible support for predictions that occupancy by fishers was associated with percent forest cover, tree-size class, or structural class diversity. Rather, occupancy was strongly associated with lands near the wilderness boundary on both sides. We speculate that the boundary between wilderness and more intensively managed forest lands provided fishers with the most suitable prey in proximity to contiguous expanses of low- to mid-elevation late-successional forests that provided optimal resting, denning, and security values. Occupancy patterns shifted toward the west and south along a precipitation gradient during the study, indicating that population distribution had not yet stabilized 5–8 years following translocation. Genetic results indicated that ≥2 generations of fishers have been produced on the Peninsula. Annual occupancy rates across the Peninsula (0.08–0.24) were lower than in other previously studied and established fisher populations, indicating that not all habitat was fully occupied or that initial estimates of the extent of habitat was overestimated. The strong selection fishers exhibited for wilderness edge and weak selection against extensive forested wilderness areas suggested that habitat managers should strive for maintaining a suitable interspersion of required forest structures and biotic habitat components, such as prey resource availability. © 2019 The Wildlife Society.     

Integrating multiple wilderness values into a decision-making model for Denali National Park and Preserve

Decisions about how to manage wilderness recreation in Denali National Park and Preserve require managers to integrate a diverse set of public values, a process that typically involves balancing tradeoffs among multiple and often competing values. While decisions about how to manage wilderness are often contentious, previous research suggests that if managers are able to predict public support for various management alternatives the decisions become more tractable. This study develops a decision-making model that integrates social, resource, and managerial values associated with the Denali wilderness experience. Specifically, stated choice analysis is used to evaluate the choices overnight wilderness visitors make when faced with hypothetical tradeoffs among the conditions of social, resource, and management attributes of the Denali wilderness. Study findings offer an empirical approach for predicting and evaluating the likelihood of public support for Denali wilderness management alternatives.     

Reimagining the wilderness ethic to include “people and nature”

Detecting significant change in stream benthic macroinvertebrate communities in wilderness areas

A major challenge in the biological monitoring of stream ecosystems in protected wilderness areas is discerning whether temporal changes in community structure are significantly outside of a reference condition that represents natural or acceptable annual variation in population cycles. Otherwise sites could erroneously be classified as impaired. Long-term datasets are essential for understanding these trends, to ascertain whether any changes in community structure significantly beyond the reference condition are permanent shifts or with time move back to within previous limits. To this end, we searched for long-term (>8 years) quantitative data sets of macroinvertebrate communities in wadeable rivers collected by similar methods and time of year in protected wilderness areas with minimal anthropogenic disturbance. Four geographic areas with datasets that met these criteria in the USA were identified, namely: McLaughlin Nature Reserve in California (1 stream), Great Smoky Mountains National Park in Tennesse-North Carolina (14 streams), Wind River Wilderness Areas in Wyoming (3 streams) and Denali National Park and Preserve in Alaska (6 streams).Two statistical approaches were applied: Taxonomic Distinctness (TD) to describe changes in diversity over time and non-metric multidimensional scaling (MDS) to describe changes over time in community persistence (Jaccards Index) and community stability (Bray–Curtis Index). Control charts were used to determine if years in MDS plots were significantly outside a reference condition. For Hunting Creek, TD showed three years outside natural variation which could be attributed to severe hydrological events but years outside the natural-variation funnel at sites in other geographical areas were inconsistent and could not be explained by environmental variables. TD identified simulated severe pollutant events which caused the removal of entire invertebrate assemblages but not simulated water temperature shifts.Within a region, both MDS analyses typically identified similar years as exceeding reference condition variation, illustrating the utility of the approach for identifying wider spatial scale effects that influence more than one stream. MDS responded to both simulated water temperature stress and a pollutant event, and generally outlying years on MDS plots could be explained by environmental variables, particularly higher precipitation. Multivariate control charts successfully identified whether shifts in community structure identified by MDS were significant and whether the shift represented a press disturbance (long-term change) or a pulse disturbance. We consider a combination of TD and MDS with control charts to be a potentially powerful tool for determining years significantly outside of a reference condition variation.     

Designing eco-villages for revitalizing Japanese rural areas

Reestablishing a sound environment in rural areas has become one of the most important environmental issues in Japan, not only in rural policy but also in national land policy. Physically speaking, regeneration of natural ecosystems, reestablishment of sound material flows, and the design of rural landscapes are important areas of research and practice. Another important issue in the management of rural areas, particularly in the mountainous areas that cover 61% of the country, is the preparation of the landscape for urban dwellers. This paper considers methods for improving rural environments. The modeling of ideal eco-villages with sound natural environment, low input and sustainable material flow, and maintenance of villages through urban and rural interaction is considered. Three different types of typical eco-village models are designed in urban fringe areas, in typical rural areas and in remote mountainous areas. Further, a case-study for the search of reality in adopting such models is surveyed in Chosei-gun, Chiba prefecture as a case of an eco-village in a typical rural areas.     

Ecological solidarity as a conceptual tool for rethinking ecological and social interdependence in conservation policy for protected areas and their surrounding landscape

Policy for biodiversity conservation must evolve to cope with the increasing human footprint on natural systems. A major issue here is the need for policy for protected areas, which integrates their surrounding landscape and local human populations in the construction of socially grounded measures. To illustrate current conceptual thinking in this direction we present and provide a conceptual basis for a recent initiative in national park policy in France that is based on "ecological solidarity". In the light of other policy ideas and tools that have recently emerged for the co-construction of conservation policy, we argue that this concept provides an imaginative step towards consolidating ecological and social interdependence in biodiversity policy that goes beyond statutory park boundaries.     

Nature conservation on decommissioned military training areas – German approaches and experiences

Military training areas (MTAs) host high numbers of endangered habitats and species due to their large area, generally low fertilizer and biocide exposure, and a high dynamic of disturbances caused by military training activities. Since the end of the Cold War in the 1990s, thousands of former military properties have been closed due to international disarmament agreements. Based on a literature review, we present the importance of decommissioned MTAs in Germany for nature conservation, their number, area, and status, as well as the German approaches and experiences managing these sites. More than 119,000 ha of former military areas of high conservation value were transferred by the Federal Government to German Federal States, the German Federal Environmental Foundation, and other nature conservation organizations as part of the so-called National Nature Heritage (NNH), and an additional 60,000 ha were saved in other ways. It is a big challenge in nature conservation to establish appropriate management systems to maintain the endangered habitats and species on these sites, most of which are contaminated with unexploded ordnance (UXO). Several projects have been implemented in Germany to develop strategies to deal with UXO contamination. We discuss management options, from prescribed burning on UXO contaminated sites to the establishment of wilderness, in the light of the requirements of the European Union’s Natura 2000 network of protected areas.     

Previous Fires Moderate Burn Severity of Subsequent Wildland Fires in Two Large Western US Wilderness Areas

Wildland fire is an important natural process in many ecosystems. However, fire exclusion has reduced frequency of fire and area burned in many dry forest types, which may affect vegetation structure and composition, and potential fire behavior. In forests of the western U.S., these effects pose a challenge for fire and land managers who seek to restore the ecological process of fire to ecosystems. Recent research suggests that landscapes with unaltered fire regimes are more “self-regulating” than those that have experienced fire-regime shifts; in self-regulating systems, fire size and severity are moderated by the effect of previous fire. To determine if burn severity is moderated in areas that recently burned, we analyzed 117 wildland fires in 2 wilderness areas in the western U.S. that have experienced substantial recent fire activity. Burn severity was measured using a Landsat satellite-based metric at a 30-m resolution. We evaluated (1) whether pixels that burned at least twice since 1984 experienced lower burn severity than pixels that burned once, (2) the relationship between burn severity and fire history, pre-fire vegetation, and topography, and (3) how the moderating effect of a previous fire decays with time. Results show burn severity is significantly lower in areas that have recently burned compared to areas that have not. This effect is still evident at around 22 years between wildland fire events. Results further indicate that burn severity generally increases with time since and severity of previous wildfire. These findings may assist land managers to anticipate the consequences of allowing fires to burn and provide rationale for using wildfire as a “fuel treatment”.     

Vielfältiges Leben in Sand und Heide

Excursion in Brandenburg: Species richness in sand heathlands After many decades of an intensive military use, the former military training areas of Eastern Germany play a major role as huge, unfragmented biodiversity hotspots. While intensive agriculture causes a serious threat to many species in our cultural landscape, heathlands and dry grasslands are unique habitats on the nutrient‐poor soils in the “box of sand” of the Mark Brandenburg. But these habitats need a strong conservation management with targeted nursing measures such as removal of shrubs, grazing, soil wounding and controlled burning. However, some forest sites of the military training areas are often suitable for a wilderness development. The Heinz Sielmann Foundation pursues these nature conservation objectives and makes great nature experiences possible in the conservation areas.     

conservation in the bush: game breeding centres in South Africa

Approximately 5% of the Republic of South Africa is set aside for national parks, nature reserves, private game reserves or wilderness areas. Within these areas a large variety of animals and plant species is protected. Many of these species are indigenous to the Southern African subregion. Most of the zoological gardens in South Africa are owned privately or by a municipality. The zoo in Pretoria is the only one which has national status. In addition to facilities in Pretoria, the National Zoological Gardens owns two game breeding centres covering an area of more than 7000 ha. The game breeding centres act as important gene pool reservoirs and are used for the breeding of threatened species. They thus fulfill an important role in conserving threatened species and, in some cases, supplementing dwindling populations in protected areas.
