Protected area systems are designed in law and policy towards achieving certain policy objectives. These systems rely on legal frameworks that determine how countries designate, declare and manage their protected areas. To date, little research has been conducted on the risks faced by protected area systems. To this end, this paper aims to identify the key risks for protected area systems achieving their objectives. This is achieved through the application of Theory of Change (ToC), which is internationally recognised as the preferred method to identify underlying assumptions and risks within policy and legal frameworks. We achieve this aim through a case study analysis of the South African protected area system as embedded in law and policy. The application of the ToC method identified 25 underlying assumptions and risks which are central to the protected area system achieving its objectives. Understanding these risks allows for a better understanding of the potential failure of the system and how to avoid it. The paper then explores and discusses the identified risks in terms of existing literature and concludes by making recommendations related to further research for the identified risks.

Here, we aimed to identify important plant areas (IPAs) in the Fergana Valley, one of the most densely human-populated regions in Central Asia with a diverse array of endemic and endangered species. The IPA programme in FV aims to identify and protect a global network of plant conservation sites. We conducted a field survey from 2018 to 2021 to re-identify specimens collected from Fergana Valley and stored at the National Herbarium of Uzbekistan (TASH). An analysis of the floristic, geobotanical and collected data allowed for the identification of the badlands in the northern foothills (Chap tract and surrounding areas) as an IPA site. We modified the interpretation of criterion A for IPAs to suit the circumstances of Mountainous Central Asia and documented the distribution of 29 species in the IPAs under these sub-criteria. To our knowledge, this is the first study to identify an IPA in Uzbekistan and provide geographic coordinates with locations for the herbarium specimens used to create the IPA set for Central Asia. Our study provides a foundation for applying future IPAs in this region, addressing specific conservation challenges, such as conserving rare and endangered species that grow outside protected areas and GIS mapping of endemic species.

With the rapid development of urbanization, the habitat quality (HQ) in urban areas has been eroded. This phenomenon is destroying the balance of ecosystems, triggering the reduction of biodiversity and the decay of ecosystem service functions. The study of the relationship between urbanization and HQ in Zhengzhou City is beneficial for the reference of sustainable urban ecological planning and management. Based on landscape classification data and socioeconomic data for three years, this study analyzes the spatial correlations between socioeconomic and landscape pattern factors and HQ, compares the dynamic changes in the explanatory power of different factors, and explores the joint effects between multiple factors. The results show that: (1) The overall value of HQ index in Zhengzhou City decreased by .10 during 2000–2020, mainly occurring in suburban areas, with a small amount of HQ improvement occurring in the core areas of ecological protection, such as mountains and river channels. (2) The spatial autocorrelation of all influencing factors with HQ increased during this period, while the negative impact from socio-economic sources was stronger than the positive impact from landscape patterns. (3) Intensive human activities lead to a single habitat type, which reduces HQ; rich landscape types and complex landscape composition can enhance HQ. Improving the connectivity of blue-green landscapes helps to attenuate the negative effects of urbanization on HQ. (4) Changes of HQ in the study area and the development of multi-factor effects on HQ are driven by the Zhengzhou Metropolitan Area Plan. Urban development policies and management can build idyllic complexes at the edge of urban development, preserving pristine blue-green patches to avoid their homogenized distribution and thus slowing the decline of HQ. The above results provide new ideas for the development of sustainable urban ecology.

The agricultural and forestry use of land does not only mark large parts of the European Union, but also a significant share of land within the European ecological network Natura 2000. Member States, therefore, try to exempt as far as possible these land uses from the protection regime of Natura 2000-sites. However, at the same time, Member States latest reports on habitats and wild species of Community importance indicate that, in particular, the intensification of agriculture and forestry in recent decades has made it more difficult to improve conservation statuses or even worsened them. Hence, the aim of this article is to examine in detail the extent to which the protection regime of Article 6(2 and 3) Habitats Directive is applicable to land-use in agriculture and forestry. In this context, of particular relevance is the question of when the use of land in agriculture and forestry or individual management measures within and near Natura 2000-sites are projects for which an appropriate assessment is necessary before implementation; and which, in the case that significant adverse effects to a site cannot be ruled out, are permitted only under the reasons for exemption given in Article 6(4) Habitats Directive. The analysis includes the case law of the European Court of Justice, as well as decisions of the German Federal Constitutional Court and the German Federal Administrative Court.

Understanding what shapes the mammal species poaching in protected areas is critical to developing targeted management strategies for reducing poaching. We collected the data for poaching incidents on the GPS coordinates from 2011 to 2017 to map poaching incidents in the Pendjari Biosphere Reserve. Poaching incidents were then related to environmental and anthropogenic variables using regression analyses. The study shows that poaching is more concentrated along the main river in the Pendjari National Park. Only nearest distance to the main river significantly predicted the location of high poaching incidents. These results could be used as the starting point by the park managers when planning the anti-poaching activities.

The notion that indigenous people and local communities can effectively prevent conservation crime rests upon the assumption that they are informal guardians of natural resources. Although informal guardianship is a concept typically applied to “traditional” crimes, urban contexts, and the global North, it has great potential to be combined with formal guardianship (such as ranger patrols) to better protect wildlife, incentivize community participation in conservation, and address the limitations of formal enforcement in the global South. Proactive crime prevention is especially important for illegal snare hunting, a practice that has led to pernicious defaunation and which has proved difficult to control due to its broad scope. This paper uses interview data with community members in protected areas in Viet Nam where illegal snare hunting is commonplace to 1) analyze the conditions for informal guardianship in the study locations; 2) explore how community members can become more effective informal guardians; and 3) examine how formal and informal guardianship mechanisms can be linked to maximize deterrence and limit displacement of illegal snaring. Results indicate that conditions for informal guardianship exist but that respondent willingness to intervene depends upon the location, offender activity, and type of offender (outsider versus community member). While respondents generated numerous strategies for wildlife crime prevention, they also listed crime displacement mechanism offenders used to avoid detection. We discuss how informal guardianship can be integrated with formal guardianship into an overall model of situational crime prevention to protect wildlife and incentivize community-led deterrence of illegal snaring.

Assessing the sustainability of the harvest of animals can be done by obtaining data from processing facilities and establishing that vital attributes of the harvested animals (e.g., size, age structure, sex ratio) do not change over time. This model works if the traders operate in a free market without any regulations on what can be harvested, processed or exported, and when harvest methods and harvest areas do not change between assessment periods. Several studies assessed the harvest effects on blood pythons (Python brongersmai) in North Sumatra, Indonesia seemingly under a free market scenario, with some concluding that trade was sustainable and the others hinting at an overharvest. Indonesia has established harvest and export quotas and, internationally, trade in blood pythons is regulated through CITES, and the blood python trade clearly does not operate in a free market. Data suggest that the three (or four) slaughterhouses included in these studies processed ~27,000 blood pythons a year against a quota of 18,000. There is a risk that data from traders alone purporting to show that harvest is sustainable will lead to an increase of quotas or an abandonment of quotas altogether. There is no conclusive data to support that the harvest of blood pythons in North Sumatra is sustainable but there is sufficient evidence to suggest that a substantial part of this trade is illegal. Likewise, at a global level there are clear indications of misdeclared, underreported and illegal trade involving 10,000 s of blood pythons. While important biological information can be obtained from harvested animals, to assess whether harvest is sustainable there is no substitute for monitoring wild populations. After decades of international trade in blood pythons from Indonesia, during which at least half a million blood pythons were exported, it is all the more urgent that systematic monitoring of wild populations commences.

In May 2021, a number of people were arrested for the illegal poaching and trade of one of the most endangered freshwater turtle species in China. The large female Pelochelys cantorii individual was poached from a strict protected area, sold, and was publicly advertised on social media despite being a Class I protected species (no trade allowed) for over 30 years and in a country with one of the strictest penalties for IWT worldwide. We discuss and call for more conservation efforts to prevent the illegal poaching and trade of this threatened species. We argue that unless China meets the urgent conservation needs of this iconic species, the impending extinction of this species cannot be reversed.

The rare species Amygdalus pedunculata Pall. (Rosaceae) in arid northern China is endangered to the point of extinction. Determined to save it, the local government of Inner Mongolia Autonomous Region encouraged the herdsmen to limit grazing activities. Here, we are testing if this species could be considered as a conspicuous flagship for restoring and conserving wind-sensitive arid lands as desert steppe in northern China. We examined statistically the growing states and environmental roles of A. pedunculata populations under the comparative conditions of free and limited grazing in winter since the year 2001. This species was observed to play a critical role in preventing wind erosion and stabilising the lands, as was indicated by the formation of micro-dunes under the shrubs. This role can be attributed mainly to the crown diameters or cover from the shrubs. Under the grazing limitation condition, accompanying species and plants around the shrubs increased significantly. Regardless of free or limited grazing conditions, the shrubs were not observed to inhibit the occurrence or growth of other plants. The grazing limitation over a period of 20 years has caused the effective revival of the rare A. pedunculata species, with statistically larger and taller A. pedunculata individuals than under the free grazing condition, as well as a slightly higher population density and total crown cover. The grazing limitation policy for saving A. pedunculata is believed to be effective and the rare A. pedunculata shrub is a conspicuous flagship for helping to conserve wind-sensitive desert steppe in terms of ecosystem integrity and authenticity.

Mammal conservation in transformed landscapes depends heavily on the role of protected areas, especially for species used by local communities both within and around these areas. We evaluated the level of representation and the magnitude of the influence of humans, via human footprint, across the range of mammals used by local communities in the Department of Cundinamarca, Colombia. We emphasised the differences of the human influence at a department scale and inside Protected Areas (PA). The definition of species used by local communities refers to using a resource for its economic, religious and/or traditional value. Specifically, we addressed whether there is a difference between the magnitude of human influence inside and outside the PAs and if the impact is greater on threatened species, species with greater or lesser representation or according to their use. We found 43 species subject to use in our analysis, with low values of representation when compared with global targets (X̄ ± CD = 10.69% ± 4.99) and with high values of vulnerability, based on the mean value of the Spatial Human Footprint Index (HSFI) (57 ± 2.74). We found a difference of 10.72 points between the average HSFI of the Department and that of the PAs (X̄ ± CD = 10.73 ± 5.98%). This shows that the status of each species’ habitats is less impacted by human activities within PAs and that the conservation areas for all species depend largely on their presence in largely transformed landscapes. Although this seems an expected outcome, the Department of Cundinamarca is one of the less represented on PAs at a national level and has suffered from severe fragmentation; thus, our results highlight the need for improving and expanding the current PA system as most species, especially those subject to use, will depend on their existence for their conservation on the long run.
