Botanical Survey of South Africa

Introduction

The Botanical Survey of South Africa functioned as a national botanical inventory and research program centered in Pretoria, tasked with documenting the vascular plants, bryophytes, lichens and fungi of South Africa, Lesotho, and Eswatini through specimen collections, mapping and taxonomic synthesis linked to institutions such as the South African National Biodiversity Institute, the Royal Botanic Gardens, Kew, the Natural History Museum, London, the Smithsonian Institution and the Missouri Botanical Garden. Initiatives were coordinated with academic partners at the University of Cape Town, the University of Pretoria, the Stellenbosch University and the University of the Witwatersrand, and projects intersected with conservation agencies including SANBI and international programs such as the Convention on Biological Diversity, the International Union for Conservation of Nature and the Global Biodiversity Information Facility.

Established during the early 20th century within the Department of Agriculture (South Africa), the Survey evolved through collaborations with colonial and postcolonial institutions like the Kew Gardens network, the Royal Society and the British Museum (Natural History), reflecting botanical priorities of the Union of South Africa and later the Republic of South Africa. Key figures associated with the Survey included curators and collectors affiliated with the Compton Herbarium, the Bolus Herbarium, the Schonland Herbarium and the National Herbarium, Pretoria (PRE) who corresponded with taxonomists such as those at the Australian National Herbarium, the New York Botanical Garden, the Institut de Recherche pour le Développement and the Muséum national d'Histoire naturelle. Expansion of mapping, specimen exchange and floristic synthesis paralleled global efforts by the International Botanical Congress, the Biodiversity Heritage Library and the Flora Europaea movement.

The Survey combined field expeditions, herbarium curation, systematic taxonomy and phytogeographic mapping linked to universities like Rhodes University and research councils such as the Council for Scientific and Industrial Research (CSIR). Methodologies integrated specimen-based taxonomy from collections at the Compton Herbarium (NBG) and Bolus Herbarium (BOL) with georeferencing, digitization and databases interoperable with GBIF and the Catalogue of Life, and used herbarium standards from the International Code of Nomenclature for algae, fungi, and plants and collections protocols developed with partners at the Royal Botanic Gardens, Kew and the Natural History Museum, London. Field surveys addressed habitats within the Cape Floristic Region, the Succulent Karoo, the Grassland Biome, the Savanna Biome and the Fynbos shrublands, and employed taxonomic monographs comparable to works by authors at the Royal Botanic Garden Edinburgh and the Missouri Botanical Garden.

The Survey documented major angiosperm families including Asteraceae, Fabaceae, Proteaceae, Iridaceae and Orchidaceae, and significant non-vascular groups such as Bryophyta and lichenized fungi catalogued alongside mycological treatments influenced by the Mycological Society of America and the International Mycological Association. It produced floristic accounts for genera like Aloe, Pelargonium, Erica, Aspalathus and Pelargonium and compiled checklists covering taxa recognized by the Angiosperm Phylogeny Group and revisions comparable to monographs from the Kew Monographs series. Collections included iconic South African taxa tied to regions cited by Alexander von Humboldt-style phytogeographers and taxonomists such as Robert Harold Compton and Harry Bolus.

Surveys mapped centers of endemism within recognized ecoregions such as the Cape Floristic Region, a UNESCO World Heritage site, the Succulent Karoo, the Maputaland-Pondoland-Albany Hotspot and Drakensberg highlands, documenting patterns comparable to work by the IUCN and the World Wide Fund for Nature. Analyses highlighted endemic-rich genera concentrated in the Fynbos and Renosterveld vegetation types and identified narrow endemics associated with specific substrates like fynbos sandstones and Karoo gypsum outcrops, informing priority lists used by entities such as the South African National Biodiversity Institute and the Botanical Society of South Africa.

The Survey’s assessments contributed to Red List evaluations under criteria of the IUCN Red List of Threatened Species and informed conservation planning by the South African National Biodiversity Institute and the Department of Environmental Affairs (South Africa), guiding protected area decisions within networks such as Kruger National Park, Table Mountain National Park, the Cape Point reserve and corridors supported by the National Protected Areas Expansion Strategy. Findings influenced restoration projects with NGOs like SANParks Trust and international funders including the Global Environment Facility and the Critical Ecosystem Partnership Fund, and underpinned policy instruments related to the Convention on International Trade in Endangered Species of Wild Fauna and Flora.

Outputs included regional floras, specimen catalogues and checklists published in collaboration with institutions such as the South African Journal of Botany, the Bothalia journal, monographs in the Annals of the Missouri Botanical Garden style, and digitized specimen images integrated into platforms like GBIF, the Biodiversity Heritage Library and national repositories managed by SANBI. The Survey’s taxonomic backbone aligned with authorities such as the International Plant Names Index, the Catalogue of Life and the Angiosperm Phylogeny Group classifications, supporting researchers at universities and herbaria including the Compton Herbarium, the Bolus Herbarium and the National Herbarium, Pretoria.
