It was 2006 and Ismail Ebrahim, a botanist with the South African National Biodiversity Institute (SANBI), was worried. While surveying one of the last remaining patches of renosterveld shrubland in South Africa’s Paarl region, near Cape Town, he and his team of citizen scientists found a small, yellow-flowered daisy species: Marasmodes undulata. It had long been thought extinct, with the last 200-strong population observed at the same location near the town of Paarl in the 1980s. Now, Ebrahim’s team had discovered an even smaller population, numbering just 27 individuals. The citizen scientists had to act quickly to stave off species oblivion. Competing vegetation was choking out the small daisies, so Ebrahim’s team took the calculated risk of setting fire to the site to level the playing field and stimulate seedling growth for the fire-adapted daisy. But no M. undulata reappeared at first, and those popping up in subsequent years disappeared. “Every time we went back to the site, we found less plants,” Ebrahim recalls. Why put so much focus on conserving a diminutive shrubland flower? Among the diverse inhabitants of the renosterveld, few species are more easily overlooked than M. undulata, which botanist Donovan Kirkwood of Stellenbosch University Botanical Garden affectionately called the “ugly duckling daisy” before his untimely in August. But just like other renosterveld plants, M. undulata belongs there, forming part of an ecosystem that becomes more sensitive to collapse with every species that is lost. Like a Jenga tower block, the little daisy helps keep the broader…This article was originally published on Mongabay
