Abstract
The IUCN (International Union for Conservation of Nature) Red List classifies species according to their risk of extinction, informing global to local conservation decisions. Unfortunately, important geospatial data do not explicitly or efficiently enter this process. Rapid growth in the availability of remotely sensed observations provides fine-scale data on elevation and increasingly sophisticated characterizations of land cover and its changes. These data readily show that species are likely not present within many areas within the overall envelopes of their distributions. Additionally, global databases on protected areas inform how extensively ranges are protected. We selected 586 endemic and threatened forest bird species from six of the world's most biodiverse and threatened places (Atlantic Forest of Brazil, Central America, Western Andes of Colombia, Madagascar, Sumatra, and Southeast Asia). The Red List deems 18% of these species to be threatened (15 critically endangered, 29 endangered, and 64 vulnerable). Inevitably, after refining ranges by elevation and forest cover, ranges shrink. Do they do so consistently? For example, refined ranges of critically endangered species might reduce by (say) 50% but so might the ranges of endangered, vulnerable, and nonthreatened species. Critically, this is not the case. We find that 43% of species fall below the range threshold where comparable species are deemed threatened. Some 210 bird species belong in a higher-threat category than the current Red List placement, including 189 species that are currently deemed nonthreatened. Incorporating readily available spatial data substantially increases the numbers of species that should be considered at risk and alters priority areas for conservation.

Binbin Li
Dr. Binbin Li is the Associate Professor of Environmental Sciences at the Environmental Research Center at Duke Kunshan University. She holds a secondary appointment with the Nicholas School of the Environment at Duke University. She focuses on the synergy between biodiversity conservation and sustainable development under climate change. She has produced more than 40 peer-reviewed publications in the last six years and published in top journals, including Science, Science Advances, PNAS, Current Biology, Lancet and Conservation Biology. Her work has been widely reported by major media including BBC, CNN, China Daily and others. She has served as PI for more than 10 projects in recent years and secured more than 8.5 million RMB in funding. Dr. Li has been awarded EC50 by Explorers Club, one of the world’s most inspiring explorers. She has received the Outstanding Young Talent by National Natural Science Foundation of China, one of the top talent awards in China to recognize her leading role in scholarship. She serves as the co-chair of the International Union for Conservation of Nature (IUCN) WCPA-protected planet specialist group, and serves on the IUCN Species Survival Commission, World Commission on Protected Areas and the Commission on Prevention of Viral Spillover convened by Lancet and PPATS. Dr. Li also serves on the advisory board of State Forestry and Grassland Administration and Giant Panda National Park. She is the editor-in-chief of Integrative Conservation and associate editor of Frontiers of Ecology and Evolution. She also serves on the editorial board of Conservation Biology, Global Ecology and Conservation, Biodiversity Science and National Parks. Dr. Li is engaged in science communication and nature education. She has been awarded nature photographer of the Year in the Chinese National Geography China Wildlife Image and Video Competition in 2022. She is the founder of the China Anti-bird Collision Action Alliance, the largest citizen science project in China. She is also the board director of SilverLining Conservation Center, which aims to increase the capacity of storytelling for conservation practitioners and to change public behaviors using media instruments.
Stuart L. Pimm
Stuart Pimm is a world leader in the study of present-day extinctions and what can be done to prevent them. His research covers the reasons why species become extinct, how fast they do so, the global patterns of habitat loss and species extinction and, importantly, the management consequences of this research. Pimm received his BSc degree from Oxford University in 1971 and his Ph.D. from New Mexico State University in 1974. Pimm is the author of over 350 scientific papers and five books. He is one of the most highly cited environmental scientists. Pimm wrote the highly acclaimed assessment of the human impact to the planet: The World According to Pimm: a Scientist Audits the Earth in 2001. His commitment to the interface between science and policy has led to his testimony to both House and Senate Committees on the re-authorization of the Endangered Species Act. He was worked and taught in Africa for nearly 30 years on elephants, most recently lions — through National Geographic’s Big Cats Initiative — but always on topics that relate to the conservation of wildlife and the ecosystems on which they depend. Other research areas include the Everglades of Florida and tropical forests in South America, especially the Atlantic Coast forest of Brazil and the northern Andes — two of the world's "hotspots" for threatened species. His international honours include the Tyler Prize for Environmental Achievement (2010), the Dr. A.H. Heineken Prize for Environmental Sciences from the Royal Netherlands Academy of Arts and Sciences (2006), the Society for Conservation Biology’s Edward T. LaRoe III Memorial Award (2006), and the Marsh Award for Conservation Biology, from the Marsh Christian Trust (awarded by the Zoological Society of London in 2004). Sigma Xi, The Scientific Research Society, awarded him the William Proctor Prize for Scientific Achievement in 2007. In 2019, he won the International Cosmos Prize, which recognised his founding and directing Saving Nature, www.savingnature.org, a non-profit that uses donations for carbon emissions offsets to fund local conservation groups in areas of exceptional tropical biodiversity to restore their degraded lands.
