Philip Dale Tanner obtained the BSc Agric (Hons) degree from the University College of Rhodesia and Nyasaland (1969), the MPhil (Soil Science) from the University of Rhodesia (1976) and PhD (Science) from the University of London (1989). Phil worked for 16 years at the Soil Productivity Research Unit in Marondera, Zimbabwe, initially as researcher, and for the last five years as Principal/Chief Research Officer in Charge. The unit investigated soil related agricultural problems (chemical, physical, microbiological) throughout Zimbabwe.
His focus was on plant nutrition, with special emphasis on soil acidity, phosphate and micronutrient availability.
In 1983, Phil joined Anglo American Coal in Emalahleni (Witbank), South Africa, initially with responsibility for developing the rehabilitation methodology for the open pit coal strip mines. In 1993 he set up and managed Anglo Coal Environmental Services, which assisted Anglo Coal mining operations with resolving the more complex issues of Land Rehabilitation, Water Management and Environmental Management Systems. A primary task during this period was the development and implementation of Risk Assessment and Risk Management approaches to ensure focus on key environmental issues. In 2001, he was transferred to Anglo’s Base Metals Division, becoming the Divisional Environmental, Health and Safety Manager, in which role he investigated mining related environmental issues in North and South America, Europe and Africa.
Phil retired from Anglo American in 2004 and continues to consult in the fields of Land Rehabilitation, Environmental Management and Risk Management. In 2005 he compiled the Guideline for the Rehabilitation of Mined Land, under the auspices of the South African Chamber of Mines and Coaltech 2020. Phil was a member of the team that developed the SHE Risk Management Process, now in use in a number of major mining companies. He is an Associate of Digby Wells Environmental, and was a Non-Executive Director of that company for 8 years.

From early in the 1980s, Gerard Hydenrych (deceased) was committed to the cause of environmental improvement and rehabilitation excellence within southern Africa. His passion for nature was strongly interlinked with a passion for improving peoples’ lives; it was this passion and an incredible ability to structure and manage on-the-ground teams that gained him great respect as a ‘master of land rehabilitation’ throughout the academic, consulting, regulatory and community fraternities over the past 40 years.
Starting off by managing projects on road cuttings, Gerard ventured into asbestos and gold tailings rehabilitation projects, and spent much of his later work years focusing on social upliftment and community projects. Whether planning, managing or mentoring, Gerard’s experience, dedication and enthusiasm to the discipline of land rehabilitation was exemplary.

Klaus Kellner’s fields of expertise include vegetation dynamics, with the emphasize on land degradation and desertification, restoration/rehabilitation ecology and range condition assessment of mainly the arid- and semi-arid lands in especially Southern Africa. Her has long-term experience working within the UNCCD, having been the CST (Committee on Science and Technology) Bureau Chair (2009-2011) and representing Africa regarding Desertification, Land Degradation and Drought (DLDD) matters.
Klaus is the Science and Technology Correspondent (STC) for South Africa in the CST of the UNCCD and have represented South Africa at the last 5 COP’s of the UNCCD (COP-Conference of Parties). He is also on the Roster of Experts for the UNCCD regarding Conservation and Rangeland Management. He was the Co-chair of the Advisory Group for the Provision of Scientific Advice on DLDD issues (AGSA) for the UNCCD (only 12 experts from the world served on AGSA) and is presently on the Science-Policy Interface (SPI) committee for the UNCCD. The SPI committee consists of only 20 experts from 20 countries.
Klaus has contributed to Chapters in reports and documents for the UNCCD (e.g. White papers for the 2nd UNCCD scientific conference in Bonn) and also contributed to the scoping report for land degradation and restoration assessment as required by IPBES through the UNCCD’s CST Bureau. All projects involve bio-physical and socio-economic assessment that influence the ecosystem services of rangelands and has led to the supervision and collaboration in many National, Regional and International research and development (R&D) projects. These projects include the evaluation of existing and development of new range condition assessment and restoration/rehabilitation technologies, incorporating local and indigenous knowledge that can be used as a DSS (Decision Support System) and consulting tools for future decision making. By using Community Based Natural Resource Management (CBNRM) and Participatory Action Research (PAR) approaches, efforts are made to bridge the gap between scientists, extension, environmental managers, land users and policy makers. The latter includes the synergies and collaboration between the three main Rio Conventions, i.e. UNFCCC, CBD and UNCCD Klaus has been involved in the education, training and capacity building of many learners, students, managers and extension officers in agriculture and conservation and has made presentations at international conferences and workshops in more than 30 countries (mainly on invitation) regarding DLDD. He is also the Principle Investigator (PI) of Internationally funded projects, and currently involved in Deliverable 3c (Scenarios and Models) of IPBES and co-author of Chapter 2.
Roy Lubke is Associate Professor Emeritus at the Department of Botany at Rhodes University. Roy is a botanist / plant ecologist with an interest in restoration ecology and coastal and dune systems. He is a founding director of Coastal & Environmental Services. He has been involved in restoration ecological projects in many parts of Africa and Madagascar. In recent years he has spent more time on his Grahamstown small holding, Waterloo Farm, and with his family, animals and outdoor wildlife events.
Mike Zingel’s basic training in genetics and first career in the seed industry, culminating in managing director of MayFord Seeds, launched him into his second career, wildlife management. He founded Zingela Consulting (Pty) Ltd in 2003. Mike is currently involved in research into veld assessment for wildlife management using satellite imagery and analysis of vegetation. Combined and using the software that he has recently developed, objective and repeatable mapping is generated of qualitative and quantitative aspects of a property. The outcomes facilitate management and monitoring of wildlife areas.
This research and its application in the veld was done simultaneously with investigations into rehabilitation of disturbed areas. This lead to his devising the Biomosome ®range of seed products, based on biome and plant succession principles. A recent development is the application of these seed products and plant succession principles to rehabilitation of mine properties and environmental civil engineering. This was introduced in a poster presentation at the LaRSSA congress in 2014. The software that he has developed for satellite image classification and for vegetation analysis is available for use under licence and is continuously updated and supported. With adaptation it is applicable to vegetation assessment generally and not specifically to wildlife.
