Botanic gardens are increasingly important agents of plant research and conservation. A large number of botanic gardens have been established throughout the globe since the mid-20th century to pursue new socio-environmental missions. Others, with histories that span centuries, have also undergone a deep transformation in the context of growing attention to matters of sustainability. Bridging key aspects of the scholarly literature on the genesis of the botanical garden institution in Europe and its legacy, this article presents the re-invention of these gardens as institutions of conservation, sustainability, and social engagement as they renew their relevance in the contemporary world. This article proceeds by covering three focal points. First, it summarizes the scholarly literature on the emergence of botanical gardens in Europe and their association with the rise of modern science, the nation-state, colonialism, and empire-building. Second, it presents accounts of current scientific and biodiversity conservation endeavours as reflexive engagements with these historical legacies, decolonization initiatives, and new socio-environmental missions. Third, this article points beyond its focus on the historical transformation of the European botanical garden institution, by identifying a more widely encompassing body of scholarship that puts forth frameworks for understanding the current role of botanic gardens on a global scale.

Botanical living collections within botanical gardens are a crucial global asset for plant diversity. Special attention should be directed towards dendrological collections due to their significant contribution to biodiversity conservation, support for scientific inquiry, enhancement of educational initiatives, and engagement of the public. Introducing plants, particularly woody species, poses a significant challenge in botanical science, one that is addressed through botanical gardens and arboretums. The establishment and development of dendrological collections in botanical gardens provide a means to comprehensively represent diverse plant species from various biogeographical regions and continents. The current paper presents, for the first time, the establishment, development, status, and future perspective of dendrological collections at the Yerevan Botanical Garden, particularly in relation to the introduction of woody plants in Armenia.

Non-invasive behavioural indicators of welfare can be particularly useful for managing captive breeding populations of endangered species; these allow individual welfare to be monitored and reproductive success maximised without the need for capture and restraint methods. However, most studies focus on the behaviours whose presence or frequency can predict welfare issues; the absence of a behaviour is less frequently considered an indicator of welfare. Here, we investigate potential behavioural correlates with welfare-related health states in captive Livingstone’s fruit bats (Pteropus livingstonii), a critically endangered species that can become obese due to restricted space and reduced activity rates compared with wild populations. In this study, behavioural data were collected on males (which are particularly prone to obesity). Hurdle models were used to separately determine the factors predicting the presence or absence of behaviour and the frequency of observed behaviours. Whilst significantly lower levels of vigilance were observed in males with a larger body mass, those with diagnosed health issues were significantly more likely to show an absence of locomotion and foraging behaviour. Males with a lower body mass were also more likely to show an absence of foraging behaviour. Our study demonstrates how the absence of a behaviour can be informative as to an individual’s welfare state. This study has identified behavioural profiles that can be used to flag at-risk individuals, reducing the need for potentially stressful handling and improving our ability to safeguard the welfare of individuals within a large captive group.

Botanical gardens play a crucial role in documenting and sustaining traditional ecological knowledge (TEK) that were integral to the lives of Indigenous peoples. TEK has gained significant attention in discussions on sustainable development. Faced with threats to the maintenance and transfer of this knowledge, alternative approaches like community-based ethnobotanical gardens are emerging as effective tools for conservation. This paper details a research partnership that focused on storing and sharing the Bunun ethnic community’s TEK to conserve and promote plant and crop diversity. This collaboration further led to the co-development of an Indigenous ecological calendar detailing knowledge about crops, specifically beans. The ecological calendar emerged as an effective tool for supporting knowledge sharing, facilitating the communication of crop knowledge along with both common and scientific names. The Indigenous ecological calendar has also become a valuable tourism resource for guided tours, helping to build recognition of Indigenous knowledge, and making it accessible to future generations.

The surveillance and treatment of parasites are important features of preventative healthcare plans in zoological institutes. The parasite control strategies employed in temperate regions often involve prophylactic anthelmintic treatments during seasons where the burden of gastrointestinal parasites in fecal testing is high. These strategies are, however, not applicable in the tropics, where temperatures remain high throughout the year, allowing continuous parasitic development. A risk-based parasite management strategy was adopted by a tropical zoological institute. For parasite surveillance, routine fecal direct smears and magnesium sulfate flotations were performed to determine parasitic prevalence. The frequency of fecal checks for the year was determined by the frequency at which clinically relevant parasitism (fecal tests that resulted in the animal being treated) was detected during routine fecal checks in the previous year. A yearly anthelmintic drug-class rotation schedule was also implemented. The total number of fecal tests performed per year and the number of animals with clinically significant parasitic disease decreased by 30.0% (637/2126) and 46.9% (207/451), respectively, over the four-year period of the study. Anthelmintic class rotation also improved the efficacy of fenbendazole in treating Strongyloides spp. infecting the group of orangutans. This parasite control strategy is a targeted approach to managing preventative healthcare, reducing the work required to perform routine surveillance tests whilst maintaining the health of the collection of animals.

Many botanic gardens are flourishing, and many others can learn from those leading the way; at the same time, all can form new allegiances informed by service research. We developed this paper to plant seeds for different stakeholders interested in putting a spotlight on botanic garden tourism opportunities. It is in response to a call to action by many stakeholders across the botanic garden sector for greater public engagement, to challenge plant awareness disparity, and to ensure the vitality and viability of the sector. Our commentary considers positive, transformative service making, marketing, management, and development. We recommend holistic, integrated services via ecosystemic thinking and collaborative partnerships across the sector and with non-traditional partnerships in the design of sustainable service ecosystems. It is envisaged that service research will spur on a more responsible, ethical, moral enterprise and sustainable botanic garden tourism with opportunities to drive positive, transformative change in meeting sustainable development goals for the good of plants, people, and planet.

Cultural institutions hold a unique position of influence, serving as hubs of education and knowledge dissemination for the people they serve. Embracing sustainable energy use in buildings in zoos and botanical gardens is a commitment to environmental responsibility that reinforces these institutions as trusted sources of information and community leaders on climate change, one of the most vital issues of our time. Sustainable energy solutions can synergize operations with educational missions, allowing zoos and botanical gardens to lead by example and inspire visitors to adopt eco-friendly practices in their own lives. In this opinion paper, Phipps Conservatory and Botanical Gardens President and CEO Richard Piacentini discusses key elements in developing a sustainable building energy plan, reviews potential barriers to implementation, and makes a case for adopting regenerative thinking and new metrics for measuring success—citing example cases from Phipps’ Center for Sustainable Landscapes (CSL) project. Additionally, the paper demonstrates how green building certification systems and peer-based resource networks like The Climate Toolkit can help guide institutions in the process. Full article

Humans are biased in their preferences for animals, and this may impact the composition of zoological collections. We assessed which kinds of animals the public and zoo professionals want to preserve in zoos for the future and analyzed these lists for previously identified biases and agreement across surveyed groups. We also characterized agreement among the surveyed groups on the roles of zoos and the composition of animal collections. We surveyed people who live in the United States, members of the Association of Zoos and Aquariums (AZA), and AZA zoo and aquarium directors. There was agreement among surveyed groups on the roles of zoos, though some differences existed. Zoo professionals and the public generally agreed on the emphasis on various categories of animals for zoo collections, though some differences were noted. We found evidence of bias towards mammals, charismatic megafauna, and felids across all surveyed groups. Agreement was high between AZA members and directors and moderate between zoo professionals and the public. These results indicate that these groups are generally in agreement about the roles of zoos, how they should compose their animal collections, and what animal species, in particular, should be kept in zoos for the future, allowing zoos to compose their collections to maximize delivery on their mission goals as well as address the preferences of the public.

Water-resource challenges, encompassing both quality and quantity, pose significant threats to Florida’s ecosystems, especially in the face of climate change, rising sea levels, and rapid urbanization. This paper explores the innovative stormwater-management system implemented at Naples Botanical Garden as a model for addressing these challenges. The Garden’s approach, treating stormwater as a valuable resource, involves dry and wet retention areas, created lakes, and a unique River of Grass, mimicking natural ecosystems. This system not only mitigates flooding, but also effectively removes pollutants, recharges the aquifer, and provides a habitat for diverse wildlife. The paper emphasizes the economic, environmental, and social impacts of traditional stormwater-management practices in Florida. Naples Botanical Garden’s case serves as a guide for botanical gardens and zoos globally, showcasing the pivotal role these institutions can play in sustainable water-resource management. The collaborative design process involving landscape architects, engineers, and horticulturists ensures a holistic and aesthetically pleasing approach to stormwater management. The paper underscores the role of botanical gardens in promoting nature-based solutions, educating the public, and offering tangible steps for implementing similar systems worldwide. It can help guide regional adaptation strategies to manage stormwater as a resource. Full article

In 2015, the Arnold Arboretum of Harvard University began an ambitious plant acquisition program: The Campaign for the Living Collections. Prior to the initiative’s launch, the Arboretum underwent several years of strategic planning to assess the values, strengths, and gaps within its renowned living collection of temperate woody plants and then set goals that would profoundly shape the collection and its research and conservation potential for decades if not for centuries. Core genera, conservation value, phylogenetic breadth, biogeography, and climate change responses were among the priority themes used to generate a targeted list of 395 desiderata to acquire from wild populations. In only a few years, the Campaign’s 26 formal expeditions and other acquisition efforts have yielded 631 accessions of 263 highest-priority desiderata, representing 66.6% of the overall goal. This venture represents one of the most transformative and deliberate collection development activities at the Arnold Arboretum and among botanical gardens in the current era. These successes are due to a combination of factors that include visionary yet realistic strategic planning and goal setting, adherence to high standards of documentation and reporting, and authentic relationship building among collaborators.
