Many plants and animals are dependent on free-flowing, unpolluted water. However, many water bodies have not achieved a good ecological or chemical status according to the EU’s Water Framework Directive. Water can be influenced by many sources, such as sewage works, industry and agriculture. Good quality water is not only important for biodiversity, but also for people, since we use it as a source of drinking water and fish. EnviroPlanning can provide information on the state of streams, rivers and lakes using innovative survey techniques, assessment methods and environmental monitoring with good precision. We can restore streams and rivers to benefit fish, and implement compensatory measures when aquatic habitats are encroached.
