There are repeated calls for remote sensing observations to produce accessible data products that improve our understanding and conservation of biodiversity. The Biodiversity Survey the Cape (BioSCape) addresses this need by integrating field, airborne, satellite, modeling datasets advance limits global Over six weeks, an international team ~150 scientists collected across terrestrial, marine, freshwater ecosystems in South Africa. In situ biodiversity plant animal communities, estuaries, kelp, plankton were made using traditional field methods as well novel approaches like environmental DNA acoustic surveys. accompanied unprecedented combination airborne imaging spectroscopy lidar measurements acquired 45,000 km2. Here, we review how applied BioSCape will help us measure monitor at scale role accomplishing this.

Abstract Iterative near‐term ecological forecasting has great promise to provide vital information decision‐makers while improving our understanding, yet several logistical and fundamental challenges remain. The ecoinformatics requirements are onerous develop maintain, posing a barrier entry for regions where funding expertise limited, there developing forecasts that fulfil needs spanning spatial, temporal biological scales. Using the hyperdiverse Cape Floristic Region of South Africa as case study, we propose regionally focussed sets will help resolve faced by under‐resourced world, comparison or coupling models across scales facilitate new insights. We review existing region explore how they could be developed into set linked iterative forecasts. Comparing from different within same domain much potential insights ecologists alike. They allow us quantitatively link processes in space time, potentially revealing feedbacks, interconnections emergent properties, providing powerful tools testing decision scenarios identifying trade‐offs unanticipated outcomes. While development multiple combined span is not trivial, gains made shared pipelines feed models. Even useful do exist, can value their own right, delivering frequent up‐to‐date basis forecast other scientific research. Viewed together, approaches present compelling opportunity overcome constraints integrate organisation, ultimately understanding management ecosystems.

Grootbos Nature Reserve falls within the Cape Floristic Region of South Africa and comprises fynbos forest vegetation elements, which exist as alternate stable states are naturally maintained by feedbacks between vegetation, fire, topography climate. The objective this study was to investigate changes in extent Baviaansfontein valley order understand whether current coverage greater or lesser prior colonial settlement. Incorporating paleoecology has potential define historical ranges landscape variability that can guide restoration programs aligned occurrence. Not all landscapes suited for tree planting initiatives they harbor indigenous open is conservation value. Historical palaeoecological information especially valuable reforestation becoming more popular. Here we present a combined palynological (pollen, spores, charcoal) geochemical approach (X-ray fluorescence elemental ratios, Loss-on-ignition), evaluate historic distribution past ~250 years at Reserve. start record dominated pollen typical asteraceous fynbos, with evidence elements also present, though low abundance. After 200 (c.1750 CE–1950 CE) increased input micro- macrocharcoal, subsequent decline charcoal indicates decrease fire This coincides taxa, suggesting suppression most likely triggered expansion perhaps initiated beginning biome boundary shift. continued promoted development present-day proteoid type around ~1980 CE responsible replacement previously asteraceous-dominated type. results show occurrence have driven compositional over time but contributed expense fynbos. Considering expected warmer climate fires, not recommended. proteoid-dominated might be similarly negatively affected shift an community could occur future.
