Without Jones, the world might have lost the Mauritius kestrel, the pink pigeon, the echo parakeet and more – but the biologist’s methods are controversial

Jones challenges the classic conservation wisdom that we must first precisely understand the reasons for a species’ decline and then restore its habitat. Instead, he argues that scientists must tweak the limiting factors on a species’ population – food, nesting sites, competition, predation, disease – with practical fieldwork.
“If there’s a shortage of food, you start feeding. If there’s a shortage of nest sites, you put up nest boxes. You don’t need endless PhD students studying a species for 20 years.”
