Ep 3 of 30 / Monty Don presents a special Shared Planet in front of an audience from the Hay Festival. Naturalists have always relied on and contributed to the illustrated guide book to observe and record wildlife, but is this so today? The modern naturalist has more than just books at their disposal, with field guides on mobile phones and tablet computers giving more than just words; sounds and moving pictures too. Monty Don asks whether the traditional naturalist skills are disappearing and with them the naturalist, or whether technology in an increasingly crowded world are liberating naturalists to observe and record wildlife in a different way generating a new generation of naturalists fit for the planet they share with nature.
