New developments in the funding requirements of biodiversity science as well as rapidly developing information technology warrant a sharper focus on the way in which biodiversity data are managed. We propose that an opportunity presents itself to develop a specific set of informatics skills among a new class of data analysts in the biodiversity science community. Our consideration of capacity development specifically emphasises the need for conceptual rigour, compliance with technical data standards and the culture of data publication or data sharing. There is a pressing need for data stewardship skills and positions in the South African biodiversity science community. We describe previous and current initiatives that may help to provide the context of, and develop skills and capacity for, effective management or stewardship of biodiversity research data. The overlapping competencies of data stewardship, data curation and data preservation include: processes and activities related to the organization and integration of data collected from various sources, annotation of the data, and publication and presentation of the data such that the value of the data is maintained over time, and the data remains available for reuse and preservation. 1 The role of the data steward can be distilled into the fundamental principles of findability, accessibility, interoperability and reusability (the FAIR principles). 1 From where do biodiversity data originate? During the last 5 years, a significant component of funding for South African biodiversity science has been channelled through the Foundational Biodiversity Information Programme (FBIP). 2 The FBIP is funded by the South African Department of Science and Technology (DST) and administered by the National Research Foundation and the South African National Biodiversity Institute (SANBI). The FBIP recognises the importance of biodiversity, not only in the narrower sense of a particular discipline of scientific research (e.g. taxonomy, systematics or ecology), but also in the broader context of the relevance of biodiversity to society. Four large, collaborative FBIP projects have been funded. These projects focus on marine biodiversity (the Seakeys Project), the effect of habitat fragmentation on the faunal diversity of Eastern Cape forests, filling gaps in biodiversity information to support decisions about the exploitation of shale gas in the Karoo (the Biogaps Project), and camera trapping of mammals to assess the status of species and populations inside and outside protected areas (the Snapshot Safari Project). In 2016, 20 smaller FBIP projects were undertaken to investigate a variety of subjects, including bat monitoring in the Kruger National Park, bryozoan e-taxonomy, and a number of applied projects, e.g. the use of polychaetes as bait, and a survey of earthworms and their use in vermicomposting. The FBIP explicitly requires researchers to generate and submit research data characterised as species occurrences, species attributes or population abundance records, or devel...
