Ecosystem

An ecosystem is a dynamic complex of plant, animal, and micro-organism communities and the non-living environment interacting as a functional unit. Ecosystems vary enormously in size; a temporary pond in a tree hollow and an ocean basin can both be ecosystems.

Ecosystem services are the benefits people obtain from ecosystems.

These include:

• Provisioning services such as food and water.
• Regulating services such as regulation of floods, drought, land degradation, and disease.
• Supporting services such as soil formation and nutrient cycling.
• Economic value such as tourism.
• Cultural or social services such as health and wellbeing, recreational, spiritual, religious and other non-material benefits.

NB Culvert, screen and outfall manual, (CIRIA C786) published by CIRIA in 2019, defines ecosystem services as: ‘The many and varied benefits that humans freely gain from the natural environment and from properly-functioning ecosystems. Such ecosystems include, for example, agroecosystems, forest ecosystems, grassland ecosystems and aquatic ecosystems.’
