  • Wilderness Quality, Habitat Connectivity, and the Effectiveness of Protected Areas Diminish as Human Activities Intensify
    Item type: Journal Article
    Tu, Wenna; Crowther, Tom; Du, Yunyan; et al. (2025)
    Conservation Letters
    Intact and connected wilderness areas are vital for biodiversity conservation. The Qinghai–Tibet Plateau (QTP) hosts some of the world's most unique ecosystems. Yet, increased economic development across the QTP raises concerns about the potential negative effects of increased human pressure on the stability of this unique biodiversity hotspot. In this study, we assessed the impacts of human activities on wilderness quality, habitat connectivity, and the effectiveness of protected areas across the QTP from 2000 to 2020. During this period, wilderness areas experienced a 41.08% reduction in large, intact patches, with a notable decline in quality, particularly in the eastern region of the QTP. Habitat connectivity decreased over time, and the cost of animal migration increased, with the most striking changes in areas with the highest initial wilderness quality. Economic growth and infrastructure development had strong negative impacts on the effectiveness of protected areas, with experimental protected areas declining faster than non-protected areas during periods of high infrastructure expansion. These emergent trend highlights the significant impact of increasing human pressure on animal migration and underscore the need for adaptive management and careful monitoring to ensure protected areas effectively prevent habitat fragmentation and support animal migration across global biodiversity hotspots.
  • Relative Contributions of the Logging, Fiber, Oil Palm, and Mining Industries to Forest Loss in Indonesia

    Indonesia contributes significantly to deforestation in Southeast Asia. However, much uncertainty remains over the relative contributions of various forest‐exploiting sectors to forest losses in the country. Here, we compare the magnitudes of forest and carbon loss, and forest and carbon stocks remaining within oil palm plantation, logging, fiber plantation (pulp and paper), and coal mining concessions in Indonesia. Forest loss in all industrial concessions, including logging concessions, relate to the conversion of forest to nonforest land cover. We found that the four industries accounted for ∼44.7% (∼6.6 Mha) of forest loss in Kalimantan, Sumatra, Papua, Sulawesi, and Moluccas between 2000 and 2010. Fiber plantation and logging concessions accounted for the largest forest loss (∼1.9 Mha and ∼1.8 Mha, respectively). Although the oil palm industry is often highlighted as a major driver of deforestation, it was ranked third in terms of deforestation (∼1 Mha), and second in terms of carbon dioxide emissions (∼1,300–2,350 Mt CO2). Crucially, ∼34.6% (∼26.8 Mha) of Indonesia's remaining forests is located within industrial concessions, the majority of which is found within logging concessions (∼18.8 Mha). Hence, future development plans within Indonesia's industrial sectors weigh heavily on the fate of Southeast Asia's remaining forests and carbon stocks.
  • The elephant in the room: Madagascar's rosewood stocks and stockpiles
    Item type: Journal Article
    Wilmé, Lucienne; Innes, John L.; Schuurman, Derek; et al. (2020)
    Conservation Letters
    To prevent the illegal trade in wild species, stock management is critical given stocks function as a buffer to supply chains during lean periods or as a mechanism for market speculation. The Madagascar government with backing by the World Bank recently promoted the sale of confiscated rosewood to reach a zero‐stocks situation. To better assess options, we contrast the risks and rewards of four stock management options. Stock destruction broadcasts a potent conservation message, but provides little economic benefit. National trade can be beneficial to local socioeconomic development goals, but can lead to laundering of illegal products. International trade is fraught with risks related to illegal trade and is perceived to achieve the least related to forest and socioeconomic indicators. Lastly, banking stocks act to postpone decisions. No management option ensures a sustainable solution, but critical analyses allow better insight to the strengths and weaknesses of the available approaches.
  • Public attitudes toward biodiversity‐friendly greenspace management in Europe
    Item type: Journal Article
    Fischer, Leonie K.; Neuenkamp, Lena; Lampinen, Jussi; et al. (2020)
    Conservation Letters
    Increasing urbanization worldwide calls for more sustainable urban development. Simultaneously, the global biodiversity crisis accentuates the need of fostering biodiversity within cities. Policies supporting urban nature conservation need to understand people's acceptance of biodiversity‐friendly greenspace management. We surveyed more than 2,000 people in 19 European cities about their attitudes toward near‐natural urban grassland management in public greenspaces, and related their responses to nine sociocultural parameters. Results reveal that people across Europe can support urban biodiversity, yet within the frames of a generally tidy appearance of public greenery. Younger people and those using greenspaces for a greater variety of activities were more likely to favor biodiversity‐friendly greenspace management. Additionally, people who were aware of the meaning of biodiversity and those stating responsibility for biodiversity conservation particularly supported biodiversity‐friendly greenspace management. Our results point at explicit measures like environmental education to increase public acceptance of policies that facilitate nature conservation within cities.
  • Horticultural plant use as a so-far neglected pillar of ex situ conservation
    Item type: Journal Article
    Ismail, Sascha A.; Pouteau, Robin; van Kleunen, Mark; et al. (2021)
    Conservation Letters
    We demonstrate how native and nonnative plant taxa used as ornamentals in private and public urban green spaces can significantly strengthen plant conservation in time of extinctions by expanding the capacity for ex situ living collections and raising awareness among professional and private gardeners and plant collectors. Based on global databases, we document the current representation of threatened plant taxa in horticulture compared to collections in botanical gardens. A substantial number of threatened taxa are already used in gardening, however, there is great unused potential—especially to reach high enough representation of genetic diversity and plant material for reintroduction and restoration programs. Considering urban greening as an integral part of ex situ conservation strategies can provide critically needed additional space and human resources for ex situ collections, while increasing the often low genetic, species and phylogenetic diversity of many newly established plantings that make them vulnerable to climate change and disease risks.
  • Political Will Has Been Critical for Protecting Forests in the Brazilian Amazon and Indonesia
    Item type: Other Journal Item
    Lyons-White, Joss; Spencer, Matthew; Arif, Joko; et al. (2025)
    Conservation Letters
    Deforestation remains a prominent contributor to climate change and biodiversity loss. Yet while 76 million hectares of primary tropical forest have been lost since 2000, two thirds of tropical forests remain. What factors have been most important for protecting these forests? Unlike policies, which often have clearly defined spatial and temporal boundaries, the roles played by dynamic underlying political and economic structures, and their interactions with policies and emergent factors, can be challenging to identify. Expert knowledge can bridge this gap by revealing the full range of factors needed to achieve forest protection. Here, we conducted a Delphi study with 36 experts, focusing on the Brazilian Amazon and Indonesia. Our results highlight the importance of political will, civil society advocacy, and intergovernmental diplomacy, and shifts in the importance of different factors over time. These findings illuminate the interactions between international and national structures and policies in generating the conditions for forest protection.
