Only three percent of all animal species on this planet have a vertebral column. All other animals are so called invertebrates, such as insects, worms and even starfish. Spiders are among the less popular invertebrates, but all play an important part in a healthy ecosystem. Honeybees, earthworms and many more play an important role at different stages of the lifecycle of plants, which we depend on for nutrition.

Some invertebrates are indicators of habitat quality and have therefore had particular attention paid to them. The white-clawed crayfish (Austropotamobius pallipes), for example, needs clean, mineral-rich water courses. Our only native crayfish is now given particular attention as an indicator species, as well as due to its decline in response to loss of good quality habitat and competition with a non-native species, the American signal crayfish. White-clawed crayfish are protected under the provisions of both the Habitat and Species Directive (as amended )and the Wildlife and Countryside Act 1981 (as amended).

Aquatic invertebrate surveys

Did you know?

Did you know that most butterfly species have a specific food plant for their larvae, and will only lay their eggs on these plants? For example, the rare marsh fritillary butterfly needs a plant called devil's bit scabious to complete its reproductive cycle.
