- ItemIUCN Red List of Ecosystems(2018-06-21) Slingsby, Jasper; Altwegg, ResIn South Africa, ecosystems listed as either Critically Endangered or Endangered are prioritised for conservation efforts which are intended to reduce the rate of ecosystem collapse and species extinction. Previous assessments were based on a nationally accepted and scientifically rigorous framework, but the IUCN have recently published a new assessment framework that has subtle differences to the existing South African system. There is pressure for South Africa to comply with the international standards such that the national assessment can be comparable with other assessments across the globe. The technical methods of the IUCN and South African Red List of Ecosystems (RLE) were tested on South African terrestrial ecosystems focusing on two criteria that assess spatial aspects and one focusing on functional aspects of ecosystem decline. Comparatively, there are differences in the number of threatened ecosystems identified by both technical methods which are mostly owed to (i) the proposed IUCN RLE technical method for subcriterion B1 (extent of occurrence) and (ii) sub-criterion A2b which identifies ecosystems that are likely to be at risk in the near future. Despite these differences, there are immense benefits for complying with the international standards. These include (i) the assessment being repeatable, (ii) consistent application and comparison across all realms, (iii) contribution towards the establishment of the global list of ecosystems at risk of collapse and (iv) eligibility for international funding on biodiversity conservation and research.

- ItemA near real-time satellite tool for monitoring and mapping ecological impacts in Fynbos(2018-06-22) Slingsby, Jasper; Moncrieff, Glenn; Wilson, AdamSatellite remote-sensing time-series are increasingly being used to examine the state and evolution of vegetation in novel ways. These approaches are considered the ‘Holy Grail’ for monitoring biodiversity and global change impacts at spatial extents and scales relevant for management purposes. In South Africa, they could contribute to environmental management through providing regularly updated information on ecosystem condition and land cover transformation; monitoring compliance with environmental legislation or environmental impact assessment recommendations; providing tools and alerts to aid land managers; and collecting data to aid global change research. We present an innovative approach to monitor and predict natural land surface processes and evaluate nearreal time changes in fynbos ecosystems. The approach includes statistical models relating time-series of satellite-derived vegetation indices, climate data and fire history to predict vegetation signal and identify deviations from natural variation. The tool is easily applied to other fire-prone ecosystems such as the Mediterranean Basin, California or South Western Australia, or could be adapted to any ecosystem by substituting the time-series model with one that adequately describes temporal fluctuations in vegetation activity for that ecosystem.
