In 1997 a new trail, the Adventurers' trail, will open. This trail explores Adventurers' Fen, and is ideal for birdwatchers as it includes several new hides with views of the Mere and other water bodies which could not previously be seen. In the summer the reserve is teeming with insect life. Many different dragonflies and damselflies can be seen patrolling the dyke edges and droves. Butterflies feed on the nectar-rich fen meadows, including the famous Swallowtail.
Bird life provides interest throughout the year, with many waterfowl overwintering.
In the spring the distinctive songs of the Reed and Sedge Warblers can be heard throughout the reserve. Sometimes the extraordinary whirring song of the Grasshopper Warbler fills the air, giving the place an almost jungle-like feel. The Reserve is managed intensively to protect and maintain the delicate balance of species which has built up over the years. Much of the management tries to recreate the old systems of fen working which persisted for hundreds of years, allowing species to become dependant on the practices. For example the Sedge plant, Cladium mariscus , is harvested every year and sold for thatching roofs.
