Earthwatch's Jane Nijssen, one of the competition judges says, "The nature writer of the year competition is a great opportunity for budding authors to develop their writing skills and for the winners to show off their talent to a huge audience in a national magazine. When people write about a subject that they are passionate about, they often surprise themselves with how easily the words flow. Get out, get inspired by nature and have a go!"

Up for grabs is a fantastic prize of a place on one of Earthwatch's unique expeditions: on South Africa's Scavenger Species the winner will scour South Africa's North West Province for hyaenas, vultures and other scavengers to better understand their vital role in this spectacular ecosystem; on Amazon Riverboat Exploration they will join boat-based surveys of river dolphins, giant otters, caiman and macaws, and land-based surveys of peccaries, monkeys and birds; or on Mammals of Nova Scotia they will explore the rugged Nova Scotia coastline and study its wildlife to help provide valuable data about the impacts of climate change.
