Peter Kenneth Latz (born 1941) is an Australian specialist in agrostology, botany, and ethnobotany, as well as an author originating from Central Australia. Over a span exceeding five decades, he partnered with the Eastern and Western Arrernte, Alyawarre, Anmatyerre, Pintupi/Luritja, Pitjantjatjara/Yankunytjatjara, and Warlpiri communities to record and disseminate their cultural and scientific understanding of plants native to central Australia. While much Indigenous botanical wisdom has vanished in other regions of Australia, it has been preserved in the Red Centre largely due to his efforts. Latz has contributed extensively to literature on Australian flora, with a particular emphasis on arid zone grasses, vegetation patterns, and Aboriginal applications of plants.
Early life
Latz was born in Alice Springs in 1941 and was raised within the Arrernte community at Ntaria / Hermannsburg Mission, situated approximately 120 km west of Alice Springs. As the child of Lutheran missionaries, he grew up alongside Arrernte children and acquired traditional bush survival techniques from them. This formative experience influenced his development into a foremost non-Indigenous authority on desert flora and their medicinal and culinary uses. In his early adult years, Latz held various roles including stockman, road train driver, buffalo handler, snake catcher, and stock inspector. Beginning in 1959, he worked as a ringer at Mount Riddock Station.
Botany
Latz completed a bachelor's degree in Zoology and Botany at the University of Adelaide. In 1978, he undertook a visiting fellowship at the Australian National University (ANU) to research Aboriginal land management practices. Subsequently, he pursued a Master's degree at the University of New England, concentrating on Indigenous plant uses such as bush tucker and bush medicine. By 1982, his M.Sc. thesis titled Bushfires and Bushtucker: Aborigines and Plants of Central Australia positioned him as a national leader in studying Aboriginal utilization of native flora.
Northern Territory Herbarium
In 1970, Peter was appointed botanist at the Northern Territory Herbarium, a position he retained for four decades. He oversaw botanical collection and research throughout the Northern Territory during a period when much of the region remained scientifically uncharted. Leading expeditions to identify and describe rare plant species, he expanded the Alice Springs Herbarium’s holdings to over 50,000 specimens together with colleague David Albrecht. His work included collaboration with Aboriginal botanists to document plant names across nine Indigenous languages.
Peter conducted the inaugural botanical survey of the Wessel Islands and carried out assessments of Kings Canyon to evaluate its suitability for designation as a national park. By identifying distinctive flora that bridged Tasmania and northern regions, he underscored its unique botanical significance which contributed to the creation of Watarrka National Park in 1989.
Bushfires and Bushtucker (1995)
During his tenure at the NT Herbarium, Latz authored Bushfires and Bushtucker, a seminal publication merging Western scientific approaches with Aboriginal knowledge concerning central Australian bush foods and medicines. The book has seen multiple reprints with an updated edition released in 2018. Prior to this work, many native species were insufficiently identified and detailed information about their uses was limited. To address these gaps, Latz immersed himself in living off the land while consulting numerous Aboriginal experts to record previously undocumented knowledge.
This book is highly valued for its scientific rigor as well as its cultural and historical insights; many traditional foods described are no longer widely consumed due to preparation difficulties and evolving tastes. Bushfires and Bushtucker has impacted research into Aboriginal plant use techniques, medicinal compounds found in Eremophila, land management strategies including fire regimes, descriptions of new Acacia species, and arid zone fire ecology.
The 2018 version includes updates to over one hundred species names reflecting recent botanical findings while preserving familiar common names alongside Aboriginal terminology. Latz also released an abridged edition entitled Pocket Bushtucker, which became popular among readers. Moreover, he developed the photographic exhibition Desert Abstracts, which toured six towns across the Northern Territory accompanied by guided botanical tours.
Latz chose not to accept royalties from Bushfires and Bushtucker, recognizing that its content is grounded in shared Aboriginal knowledge; all proceeds are directed to support the Institute for Aboriginal Development.
The Flaming Desert (2007)
Latz’s second significant publication explores the prehistoric and ecological aspects of central Australia, with a particular focus on how Aboriginal communities utilized fire to influence vegetation patterns. The book examines spinifex (Triodia species), plants sensitive to fire, and the effects of burning on both desert and tropical ecosystems, including their animal inhabitants.
Blind Moses: Aranda man of high degree and Christian evangelist (2014)
Shifting from botanical studies to biography, this third work narrates the story of Moses Tjalkabota Uraiakuraia, a Western Aranda individual who converted to Christianity following the arrival of Lutheran missionaries in 1877. Drawing upon his extensive knowledge of the Aranda people, Latz provides rare perspectives on this prominent historical figure.
Tough, Tantalizing or Tasty: Stories about Australian desert plants (2021)
Revisiting the flora of Central Australia, Latz offers a curated field guide enriched with personal stories from his numerous desert explorations. The publication underscores Indigenous botanical knowledge and advocates for greater scholarly attention on central Australian plant species and their environments. It highlights critical concerns such as fire management, the sustainable development of bush foods, and conservation efforts.
Volunteer Work
Latz contributes actively to the yearly fossil excavation program at Alcoota Scientific Reserve, aiding in uncovering important specimens including Dromornis stirtoni, Thylacinus potens, Wakaleo alcootaensis, Kolopsis torus, Plaisiodon centralis, and Palorchestes painei. He stresses that desert vegetation co-evolved with browsing animals like camels rather than grazing livestock such as cattle.
Within the Alice Springs area, Latz dedicates significant volunteer efforts: delivering presentations on weed threats; guiding bushwalks for the Alice Springs Field Naturalists Club; providing weed removal training for Alice Springs Landcare; advising the Olive Pink Botanic Garden on native plant maintenance; consulting with the Arid Lands Environment Centre regarding land stewardship; and mentoring emerging Aboriginal botanists. His work prioritizes controlling invasive species like buffel grass by tracking its proliferation and effects on indigenous vegetation in pastoral zones. On his own property, Latz demonstrates land rehabilitation methods and has restored a fenced riparian zone free from cattle intrusion, which now serves as a naturalist destination showcasing native flora diversity.
Awards and honours
In 2015, Latz was honored with the Northern Territory Landcare Award under the Australian Government’s Individual Landcarer category.
Australian Natural History Medallion
Latz received the Australian Natural History Medallion in 2021, awarded by the Field Naturalists Club of Victoria. His nomination was shared with "the Aboriginal botanists of Central Australia," put forward by the Alice Springs Field Naturalists Club. This prestigious medallion acknowledges exceptional achievements in Australian natural history. The nomination emphasized the vast traditional knowledge held by central Australian Aboriginal communities and highlighted Latz’s role in compiling and disseminating this distinctive scientific, cultural, linguistic, and historical material—underscoring its international importance due to the region’s largely undisturbed native landscape.

Latz is credited with the identification of numerous new plant species and has had a variety of species named to honor his contributions.
