Abstract

It is theoretically possible to protect large fractions of species in relatively small regions. For plants, 85% of species occur entirely within just over a third of the Earth's land surface, carefully optimized to maximize the species captured. Well-known vertebrate taxa show similar patterns. Protecting half of Earth might not be necessary, but would it be sufficient given the current trends of protection? The predilection of national governments is to protect areas that are "wild," that is, typically remote, cold, or arid. Unfortunately, those areas often hold relatively few species. Wild places likely afford the easier opportunities for the future expansion of protected areas, with the expansion into human-dominated landscapes the greater challenge. We identify regions that are not currently protected, but that are wild, and consider which of them hold substantial numbers of especially small-ranged vertebrate species. We assess how successful the strategy of protecting the wilder half of Earth might be in conserving biodiversity. It is far from sufficient. (Protecting large wild places for reasons other than biodiversity protection, such as carbon sequestration and other ecosystem services, might still have importance.) Unexpectedly, we also show that, despite the bias in establishing large protected areas in wild places to date, numerous small protected areas are in biodiverse places. They at least partially protect significant fractions of especially small-ranged species. So, while a preoccupation with protecting large areas for the sake of getting half of Earth might achieve little for biodiversity, there is more progress in protecting high-biodiversity areas than currently appreciated. Continuing to prioritize the right parts of Earth, not just the total area protected, is what matters for biodiversity.

Stuart L. Pimm

Doris Duke Distinguished Professor of Conservation Ecology in the Nicholas School of the Environment and Earth Sciences

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.

Binbin Li

Assistant Professor of Environmental Science at Duke Kunshan University

Dr. Binbin Li is the Assistant Professor of Environmental Sciences of the Environmental Research Center at Duke Kunshan University. She holds a secondary appointment with Nicholas School of the Environment at Duke University. Her research focuses on loss of biodiversity, endangered and endemic species conservation such as giant pandas, priority setting and management of protected areas, and promotion of innovative technology, markets and policies to solve conservation problems and local community development. Dr. Li got her PhD in Environment from Duke University (2017), M.S in Natural Resources and Environment from University of Michigan (2012). and B.S in Life Sciences with a dual degree in Economics from Peking University (2010).

Dr. Li’s work covers the identification of conservation priorities and national parks in China, impacts of One Belt One Road on biodiversity, giant panda conservation and management via Footprint Identification Technique (FIT), impacts of oil palm and rubber plantations on biodiversity in Southeast Asia, influence of national environmental policies on human-wildlife conflicts, and behavioral study of endemic species. She is also a member of the IUCN SSC Small Mammal Specialist Group.

Dr. Li is engaged in science communication and nature education. She is a signed nature photographer at Swild in China. During 2013-2015, she served as a science advisor for Disney nature documentary “Born in China”. She is devoted in using photography, social media, drama, and other art formats to promote conservation science in the public.
