In a survey of 100 Herefordshire ponds, carried out by Anthea Brian & Beryl Harding between 1987 and 1991, it was found that ponds varied a lot in the numbers of plant species and animal types, with the majority of ponds having only limited numbers of each. Ponds with high numbers of plant species tended to have more animal types, showing the close dependence of animals on plants.
