A high proportion of plant species is predicted to be threatened with extinction in the near future. However, the threat status of only a small number has been evaluated compared with key animal groups, rendering the magnitude and nature of the risks plants face unclear. Here we report the results of a global species assessment for the largest plant taxon evaluated to date under the International Union for Conservation of Nature (IUCN) Red List Categories and Criteria, the iconic Cactaceae (cacti). We show that cacti are among the most threatened taxonomic groups assessed to date, with 31% of the 1,478 evaluated species threatened, demonstrating the high anthropogenic pressures on biodiversity in arid lands. The distribution of threatened species and the predominant threatening processes and drivers are different to those described for other taxa. The most significant threat processes comprise land conversion to agriculture and aquaculture, collection as biological resources, and residential and commercial development. The dominant drivers of extinction risk are the unscrupulous collection of live plants and seeds for horticultural trade and private ornamental collections, smallholder livestock ranching and smallholder annual agriculture. Our findings demonstrate that global species assessments are readily achievable for major groups of plants with relatively moderate resources, and highlight different conservation priorities and actions to those derived from species assessments of key animal groups.

Resumen en inglés

In Mexico’s western Sonoran Desert along the Gulf of California is a place made extraordinary by the desert solitude, the dynamic sea, and the people who live there—the Seris. Central to the lives of these people are the sea and its shores. Shells on a Desert Shore describes the Seri knowledge of mollusks and includes names, folklore, history, uses, and much more. Cathy Moser Marlett’s research of several decades, conducted in the Seri language, builds on work begun in 1951 by her parents, Edward and Becky Moser. The language, spoken by fewer than a thousand people today, is considered endangered. Marlett presents what she has learned from Seri consultants over recent decades and also draws from her own childhood experiences while living in a Seri village. The information from the people who had lived as hunter-gatherers provides a window into a lifestyle no longer recalled from personal experience by most Seris today—and perhaps a window into the lives of other peoples who made the Gulf’s shores their home. The book offers a wealth of information about Seri history, as well as species accounts of more than 150 mollusks from the Seri area on the central Gulf coast. Chapters describe how the people ate mollusks or used them medicinally, how the mollusks were named, and how their shells were used. The author provides several hundred detailed drawings and photographs, many of them archival. Shells on a Desert Shore is a fresh, original presentation of a significant part of the Seri way of life. Unique because it is written from the perspective of a participant in the Seri culture, the book will stand as a definitive, irreplaceable work in ethnography, a time capsule of the Seri people and their connection to the sea.
