The Mere

A wide stretch of water, about 3 feet deep at maximum and fed by boreholes

Picture of the mere

This habitat is clear, clean, slow-flowing water. It is fed by boreholes at one end, and exits the site via a dam and tunnel system at the other; thus it is very slow to freeze, even in the coldest weather. The basin is in part exposed gravel, chalk and stone, in part sediment (deep in places). The water is open, as it has proved impossible to grow water plants such as Nuphar lutea and similar because of the depredations of the water-fowl. It is vulnerable to drought, and dried out in 1997.

The water is edged by heavy vegetation on all sides, which provides much good cover and nesting places.
