Almost a century ago, long before biodiversity expressed a scientific value for nature, Latin American countries began establishing national parks. Today, they represent over 6 percent of Latin America’s landmass. By considering national park creation across a broad regional span and six crucial decades, this article explains a mode of state formation focused on caring for nature instead of just exploiting it. It examines how national parks expanded in the region by identifying three consequent trajectories: the use of these conservation units for frontier development in Argentina and as part of a broader project seeking social justice in Mexico; the formation of more haphazard park initiatives in various countries, taking Brazil and Chile as main examples; and the development of ecologically coherent park systems through the cases of Peru and Colombia. The article also addresses the role of science (especially forestry) and international cooperation in shaping national parks. In this manner, it uncovers the paths that faded from view after the idea that parks intend to protect biodiversity took hold and illustrates a rarely acknowledged aspect of state expansion.

Protected areas worldwide are strongholds for safeguarding biodiversity, natural habitats, ecosystem services and cultural values. Yet despite their importance, the effectiveness of protected area management varies greatly. Indonesia is a biodiversity hotspot, with 554 protected areas that cover 27 million ha across the archipelago. To assess and improve the management effectiveness of these protected areas, the Government of Indonesia applied an adapted version of the Management Effectiveness Tracking Tool (METT) to assess 422 of the country's protected areas, of which 170 were repeatedly assessed in 2015, 2017 and 2019. We investigated the METT score changes across these protected areas and the factors explaining the varying scores. Over the study years, METT scores significantly improved (mean increase of 44.1%). National parks had the highest mean score, which was 13.4 points higher than other protected area types. After correcting for spatial autocorrelation using a generalized least-squares model, we found that METT score increase was positively influenced by year of assessment and having a well-resourced management authority, with no influence of protected area size or mean protected area budget allocation per ha. The assessments identified five main threats to protected areas: poaching, illegal logging, human settlements, tourism and non-timber cultivation. The widespread and repeated use of METT across the protected areas of Indonesia and the increasing METT scores indicate an overall improvement in management and professionalism. Building on the foundational work in our study, future studies should assess the association between METT scores and progress made towards achieving the conservation objectives of protected areas.

Extensive cattle ranging is an important economic activity in mountains, with diverse effects on native mammal communities. The effects of cattle Bos taurus can be negative, positive or neutral, mostly depending on the stocking rate. We examined the effect of cattle on the diversity and abundance of native mammalian species in the Austral Yungas region of Argentina, considering environmental variables, land protection status, and human influence. Using 12,512 trap-nights from 167 camera-trap stations over 11 years (2009–2019), we calculated a relative abundance index using camera events and used generalized linear models to estimate the effect of cattle on small mammals, large herbivores, species of conservation concern and felids. Cattle had different effects on each group of native mammals. We observed a lower abundance of large native herbivores and the absence of small mammals in areas with high cattle abundance. The tapir Tapirus terrestris, jaguar Panthera onca and white-lipped peccary Tayassu pecari are rare in the Yungas and therefore potentially vulnerable to extinction there. Conservation of small felids and low cattle abundance could be compatible, but felids are threatened by other anthropogenic influences. Native mammalian diversity and richness were related to land protection status. The entire ecoregion is potentially suitable for cattle, suggesting the potential for further threats, and that cattle should be excluded from strictly protected areas. To ensure extensive cattle ranging is compatible with wildlife conservation in areas where exclusion is not possible, we recommend improved management of cattle and moderate stocking rates.

This article explores the role of business in supporting and benefiting from nature protection during the second half of the nineteenth century. It begins with the support of business for protecting scenic wilderness in California and the creation of Yellowstone, as well as the role of the railroads in encouraging easterners to visit to the nation’s western national parks—all designed to create economic value by promoting tourism. It then examines the efforts of a wide range of business interests to protect the White Mountains of New Hampshire and the Adirondack forest in New York State. The later effort was led by business interests from New York City who worried that deforestation would impair freight traffic on the Erie Canal and Hudson River as well as endanger the city’s water supplies. This article compliments Hay’s research on business and conservation during the Progressive Era by demonstrating that business also played a critical role in supporting wilderness and forest protection.

Societal debates about climate change have rekindled interest in environmental history approaches. This review article considers three recent books in African environmental history, on the Kruger National Park, the East African Groundnut Scheme, and on infrastructure in postcolonial Dar es Salaam. Why is it important to study the empire–environment nexus? How do African experiences relate to discussions on the Anthropocene? Taking environmental dynamics into account enriches understandings of social, political, and cultural relationships and sheds light on imperialism and its complex legacies. This article makes the case for the importance of environmental history as a category of analysis, encouraging other scholars to think “with” the environment in broader debates concerning power, identity, and social change.

Invasive species management in natural landscapes is generally executed at the scale of independent jurisdictions, yet the ecological processes and biodiversity to be protected from invasion occur over large spatial scales and across multiple jurisdictions. Jurisdictional land boundaries can influence the flows and dynamics of ecological systems, as well as the social systems that exist in these complex landscapes. Land management entities in large, protected area–centered ecosystems may use different approaches to address cross-boundary management challenges. To understand these differing strategies and their effects on cooperative invasive plant management, we interviewed employees with federal, county, and state agencies, research organizations, nonprofits, and local stakeholder groups in two national parks and their surrounding lands in California, USA. Although all participants stressed the importance of working together, they did so along a continuum of strategies ranging from simple communication to coordination of independent efforts to active collaboration. Barriers to collaboration can be categorized as originating within or externally to the management unit, including limited resources, differing agency priorities, paperwork requirements, and lack of support by higher-level managers. Strategies to reduce barriers depend on where they originate.

Protected areas (PAs) are intended to preserve natural places, aiming to sustain ecosystem functionality and preserve biodiversity. However, PAs are spatially static, while major threats to biodiversity, such as climate and land-use change, are dynamic. The climatic conditions represented in a PA could vanish in the future and appear in other places more or less far away from the PA; these places could be considered as recipient areas potentially suited to receive propagules from the source PAs, which tend to lose the climatic conditions that motivated their protection. This study estimates the current and future climatic representativeness of mainland Iberian national parks by identifying future areas with a similar climate to those existing now in the parks and taking into account the degree of anthropogenic alteration and protection. We identify a network of ecological corridors connecting Iberian national parks with their recipient areas, as well as discriminating those most conflicting areas that impede network connectivity due to their degree of land-use transformation. Our results identify important areas for maintaining the climatic representativeness of Iberian national parks in the future, showing a substantial reduction in the climatic representativeness of the Iberian national parks. Although most of the recipient areas now have forest and semi-natural land uses and more than half of their whole area has protected status, current land uses in the Iberian Peninsula severely obstruct the corridor network connecting the parks and recipient areas.

This article examines debates about how to manage elephants in Kenya’s Tsavo National Park as a jumping off point for exploring the relationships among the local, national, and global constituencies that converged in the formulation of wildlife policy in Kenya during the 1950s and 1960s. Bridging the colonial and postcolonial years, the so-called Elephant Problem in Tsavo, while leveraging different international constituencies, pitted different administrative philosophies against one another and drew out different understandings of the application of ecological sciences in national parks. The result was a paralysis of policymaking which sparked an overhaul of the wildlife departments in the 1970s.

Nature conservation is a complex venture, with a great impact, among other things, on local and national power relationships. Nature conservation also depends on a wide set of variables to determine any one planned initiative's long-term success or failure. This article explores what made the difference between success and failure in the history of nature conservation under Mussolini's regime. Many parks were planned in those years in Italy, but only a handful were effectively instituted. This essay will address the following questions: What were the reasons behind the planning and creation of these national parks? What was the role of Fascist ideology in determining the long-term success of a park proposal? Was there anything specifically Fascist in Italian nature conservation in the 1920s and 1930s? Which other variables impacted on the involved decision-making processes?
