“…When focusing on endemic species, the situation is critical in both Colombia and Ecuador. The 83% (36/43) of endemic palms are potentially threatened in the Chocó and Andes of Colombia (Table 2) which is much higher than the 45% of all Colombian endemic tree species assessed as threatened (Lopez‐Gallego & Morales‐Morales, 2023). This level of threat is equivalent to those reported for Madagascar where 86% of the mostly endemic species were assessed as threatened (Rakotoarinivo et al, 2014, 2020) and close to the 78% of endemic plants assessed as threatened in Ecuador in general (León‐Yánez et al, 2011).…”

Societal Impact StatementPalms provide vital plant resources and ecosystem services to people across the tropics. To improve conservation guidance, a “health check” of palms in two highly threatened biodiversity hotspots in Colombia and Ecuador was undertaken. Palms are very diverse in these regions, but over one third are threatened with extinction now, especially among endemic species. Widespread and useful palms are also under intense human pressure and need to be prioritized in terms of sustainable management practices. Given the importance of palms for humans, inclusive conservation actions should be continued in both countries in order to safeguard this resource.Summary Palms provide central plant resources to societies in the tropics, especially in the Global South. The western Pacific and Andean regions of Colombia and Ecuador host two hotspots of biodiversity. To prioritize conservation policies towards palms, we undertook a conservation assessment of species in the region. We compiled a taxonomically verified database of specimens collected in both hotspots. We inferred preliminary conservation assessments using International Union for Conservation of Nature (IUCN) Criteria B. In addition, we evaluated the level of exposure of palms to human use and population density using the anthrome concept. We documented 144 native palm species in 33 genera occurring in both hotspots of Colombia and Ecuador. Of these, 55 are endemic to this region. We recorded 133 species for Colombia, 43 endemic, and 71 species for Ecuador, 9 endemic. A third of all palm species in the region are potentially threatened with extinction (50/144) and 12 as preliminary Critically Endangered. Aiphanes and Geonoma have the highest number of threatened species. In total, 60% of palm specimens were collected in the “low human impact” anthrome type. In contrast, 41% of specimens occur in high human density areas. The two hotspots of biodiversity in Colombia and Ecuador are very diverse in palms. However, we show that this diversity is under threat and is predominantly found in areas impacted by human activities. Extinction risk is highest in endemic species in both countries. Widespread and useful palm species also face threats linked to overexploitation or habitat loss. Inclusive conservation measures should be designed to conserve, together with communities, this plant resource.

“…One possible alternative explanation for the positive relationship between number of local common names and national vulnerability status may be that most of the documented plants are regional, and so may be so widespread that the species is considered of little conservation concern or not yet in need of evaluation. Lopez-Gallego & Morales-Morales (2023) found that endemic and threatened species of trees were not uniformly distributed across the biographical regions of Colombia, and for trees in the Amazonia and Guyana shield regions, most species were labeled as Least Concern by the IUCN, because of large extant of occurrence (EOO)—the estimated minimum convex polygon that encompasses all known occurrences of a species—and lack of threats (Lopez-Gallego & Morales-Morales, 2023). The plant species included in this study may also have been assessed as Least Concern for these reasons.…”

Can’t carve air, can’t weave names: Plant species used in Colombian artisan crafts are not equally assessed for vulnerability at the international and national level

Humanity has maintained cultural connections with our environments for time immemorial. Plants and artisan crafts are a prime example, as craft purpose, skill, design, and species used can vary greatly between communities and the loss of a critical plant species can result in a loss of access to cultural craft practices. To mitigate global biodiversity loss, conservationists are faced with the challenge of assessing species vulnerability to extinction and prioritizing species for conservation funding using information instruments, like the IUCN red list. This process does not necessarily consider a species′ cultural importance. In this paper we sought to address this gap for plant species used in artisan crafts in Colombia. We aim to answer the following: (1) how represented are endemic species in artisan crafts; (2) how threatened are artisan craft species according to (a) international and (b) national vulnerability status? We used the number of species-associated common names as a proxy for cultural awareness. We found that continentally regional species were far more represented in Colombian artisan crafts than national endemics. We also found a strong positive relationship between number of common names and national vulnerability assessment status, but no statistically significant relationship for international vulnerability status. Based on our results, well-known plants used in Colombian artisan crafts are more likely to be assessed nationally than internationally. While the IUCN is thorough in their recommendations, more can be done to prioritize the inclusion of conservation assessments for species based on their contributions to cultural diversity.

“…In species rich countries, like Colombia (Lopez‐Gallego & Morales‐Morales, 2023), effective approaches are needed to provide rigorous methods to rapidly assess the threat status of trees in large diverse countries. These assessment efforts are still hampered by the substantial fraction of poorly known species, or even undiscovered species, in some of the world's most biodiverse countries.…”

The publication of the State of the World's Trees (BGCI, 2021) has reinforced the growing recognition of the importance of trees and forests to Earth's environmental sustainability. Trees perform vital functions for human society, from basic carbon sequestration to making cities more livable. Trees create rich, multi-dimensional habitats for animals, fungi, and other plants. Essentially, human societies and economies rely on the health and diversity of our planet's trees (Rivers et al., 2022, this issue). With the publication of the Global Tree Assessment, we are gaining a comprehensive understanding of the threat status of trees, allowing us to prioritize conservation efforts and create more effective strategies. In this special issue of Plants, People, Planet, a compelling representation of the complex, multi-faceted, and rapidly changing issues addressed by the Global Tree Assessment is provided.The 13 articles include investigations from a number of different viewpoints and scales, from national assessments of highly diverse but relatively poorly known floras to a single protected area, from a taxonomic focus on a single important family to carefully selected but completely known groups of species, and even specific practical issues involved in the reintroduction and restoration of an endangered species.The paper by Barstow et al. (2022) focuses on the assessment of more than 90% of tree species that are endemic to Papua New Guinea. The study provides valuable information on the risk of extinction, major threats, and the conservation and research needs of the country's tree flora. The contribution by Chua et al. (2022) sheds light on the current state of knowledge regarding extinction risk to tree species in Malaysia (one of world's top megadiverse countries for tree species). The study highlights the extent and types of extinction risk faced by several keystone tree families, namely, Dipterocarpaceae,
